REW supports hdmi audio multichannel, however it doesn't seem to support spdif multichannel, only stereo. am i wrong?

I use SPDIF actually to connect to my AVR, a Logitech Z906. And with REW I'm only able to output sound to its L and R channels and naturally the subwoofer.

My computer, the Fatal1ty FM2A88X+ Killer motherboard does support HDMI audio via its AMD A10-7850K Radeon R7 4C+8G (4) @ 3.700GHz CPU. Theoratically.

I don't use the HDMI output at all at this moment. My monitor is using DVI-D and my TV is using VGA video inputs.

My question is assuming I purchase an inexpensive HDMI to SPDIF converter like https://www.amazon.ca/LinkS-SPDIF-Extractor-Converter-Chromecast/dp/B00XJITK7E for example - there are dozens of models - would REW easily recognize my 6 audio channels that it doesn't see using SPDIF, for I can measure each one individually and align them in time and frequency domain? That is without having to reconfigure every audio client/server in the computer.

Or as an alternative, could we expect REW to see all the 6 SPDIF channels natively in a future update? For that to happen I understand they would have to be demultiplexed, processed, and remultiplexed, correct?

Goal is to address, measure, and correct each and every 6 speakers connected to my Z906, which I cannot do using SPDIF. Analog audio is not an option. It's broken anyways, I purchased this board 2nd hand and no analog audio working.

Last but important, system is Fedora Linux 40, with pipewire. The Z906 has a SPDIF input + analog inputs but no HDMI.

So far REW did an excellent job for the R and L channels, but the other 4 are left unoptimized i.e. the subwoofer isn't probably in proper phase with the front speakers and the rear speakers were left unprocessed. The Z906 can be manually switched with the effects button, between 2.1 (stereo), 4.0 where front speakers are duplicated on rear speakers, 5.1 upmixing, and automatically decode multichannel 5.1 mode when compatible format is detected. Therefore it's actually optimized for stereo using convolver impulse files produced by REW. In 4.0 mode the result is terrible and in 5.1 multichannel mode, the convolver is deactivated because easyeffects supports only stereo.

I'm perfectly satisfied with my hardware for music (stereo), movies (stereo or multichannels) and my Z906. It's not hifi (with the meaning it has originally in the 70s), but it's OK. My hifi system is another project once this Fedora/Asrock is advanced enough to my satisfaction. I'm making progresss, but its step by step. My knowledge with psychoacoustics dates from the alalog era where we used compression/expansion with NE572 ICs, delay lines using TDA1022 or SAD1024 and active LPF, BPF and HPF using op amps, graphic LRC equalizers and preamps where the bass/treble were not centered at say 1kHz, but variable throughout all the audio spectrum, separately. I was a very active electronic hobbyist. I'm totally new to digital audio and there is a lot of reading to grok the entire panorama and the possibilities.

I hope I'm clear anough, it's getting late.

REW (or Java, more accurately) only supports uncompressed audio formats. HDMI can carry up to 8 channels of uncompressed linear PCM data, S/PDIF multi-channel formats are compressed bitstreams which REW cannot generate or decode.

@linuxonly: There is an alsa plugin dcaenc which converts 6ch PCM input to a DTS-encoded bitstream for transfer over SPDIF https://github.com/jesusdf/spdif-alsa-plugins/blob/master/dts/dcaenc-2/README . I have not tested it but some info is available online, IMO it will work OK.

Similarly you can use a52 alsa plugin which converts to AC3 e.g. https://git.alsa-project.org/?p=alsa-plugins.git;a=blob;f=doc/a52.txt;hb=HEAD (but DTS has a better quality).

Then just use your custom 6ch alsa PCM device in linux REW.

Thanks John, that's a concise explanation.

It took me months to get this audio setup working as it should using first alsa and pulseaudio with Fedora 38, then changing and reconfiguring everything for pipewire and wireplumber under Fedora 40 given the fact that there is no documentation. Windows is almost plug and play as far as audio is concerned; linux is far far away from that: you'll get some audio but in no way optimal. My audio clients are firefox, chromium based browsers, vlc, mpv, kodi, totem.

Is it possible to test whether or not REW could see all my HDMI channels if I selected HDMI as audio output, possibly using channel mapping, even though I do not have anything plugged to the hdmi output? I would not want to take the risk ruining my audio configuration for tests that would not even be possible. Zero configuration done yet on the hdmi, as I don't use it, never did: no hardware supporting it.

REW is a standard alsa or pulseaudio client. You can use any other player/client to check. E.g. aplay or sox for alsa, mplayer or vlc or anything for pulseaudio.

HDMI alsa devices with no connected HDMI device are often disabled as they need to receive capabilities of the remote receiver first (channels, formats https://en.wikipedia.org/wiki/Extended_Display_Identification_Data#Audio_Data_Blocks). Depends on the actual HDMI transmitter model/its driver.

Hi, thanks for your reply.

I reckon getting alsa properly setup would be the first step, but I failed miserably at that.

I already have a52 working (I think) but dca looks like a dead project. Nevertheless, despite several weeks of testing, I never was able to get any 5.1 sound working under ALSA and that was tested and retested. Lack of competences here.

Some tests I made so far, just a few, only stereo output:

@linuxonly : IMO the steps should be gradual. First make your chain work with standard PCM. Then test DD/DTS passthrough, using some DD/DTS tracks with e.g. mplayer. That will yield alsa device config which will work with DD/DTS. Then you can play with a52/dca to convert multichannel PCM and output to this tested 2ch passthrough device. Doing all of this in one step the first time right is basically impossible.

Hi, and thanks for your reply.

I already play DD/DTS (I think) using flatpak mpv and flatpak vlc through passtrough.

AAC material decodable only by Kodi flatpak using pipewire, not pulseaudio, not alsa, and only some particular flatpak commits where pipewire has not been disabled.

All other clients see the DD/DTS/AAC files as stereo and play then as stereo e.g. mplayer. I'm afraid I will need assistance. What would be the next step?

All other clients see the DD/DTS/AAC files as stereo and play then as stereo e.g. mplayer. I'm afraid I will need assistance. What would be the next step?
Click to expand...

If you have a DD/DTS source, the player needs to use passthrough, to avoid the internal decoding to PCM. Some players may do it by default (vlc, mpv??), mplayer needs to be told to do so https://mplayerhq.hu/DOCS/HTML/en/advaudio-surround.html#advaudio-surround-passthrough chapter 3.9.3

But you keep outputting to pulseaudio/pipewire, while trying to configure a PCM alsa device. You need to tell your player to use alsa directly, and disable the given device in PA/PW to keep it available for direct alsa access.

Oh that's getting interesting, we're getting closer. Thanks you so much for the mplayer page. I learn by example, not by reading thousands of pages so I appreciate the link very much.

Unfortunately, no success yet mith mplayer and my last tentative to simplify my /etc/asound.conf resulted in no audio at all on reboot and a required restore from backup because I don't know how to wipe all existing audio configuration hoping the Fedora system will reconfigure itself automatically like debian does.

I'd prefer to use pipewire directly and avoid alsa altogether whenever possible.

Tentative to simplify /etc/asound.conf
Code: 
$ cat /etc/asound.conf
#
# Place your global alsa-lib configuration here...
#

{
type hw
card Generic
}

When no alsa device is specified (you only enabled alsa audio output module) , mplayer uses device "default" which in your config is aimed at some not existing device CARD=0, DEV=1. First you should find where your default device is configured and fix that. Then still it's much safer to specify the device with e.g. https://ubuntuforums.org/showthread.php?t=1111396&p=7052441#post7052441

If your goal is to convert REW multichannel PCM to AC3/DTS spdif, then alsa path is the safest and cleanest for you. PW introduces another major layer of complexity on top of alsa - possibly resampling, format conversion etc. Also pulseaudio java connector is quite old.

Wow, this is major! 10 months I've been trying to figure that out!
Thank you so much!

Mplayer still has some error messages, but the passthrough is working.

This is not consistent with my 'aplay -L' output though, posted earlier. But looking at my 'aplay -l', it is.

Any idea how to generate a proper /etc/asound.conf so the default device is defined once and for all? And I would love for Kodi to be able to use ALSA as passthrough instead of pipewire. Never been able to get it working (the passthrough options are not showing in Kodi Audio Config page when ALSA is selected as output device.

BTW I'm waiting for an HDMI to SPDIF converter. Will try to get REW to use HDMI, might be easiest.

Created a '~/.mplayer/config' file. We'll see What happens with different formats...

Code: 
afm=hwac3
ao=alsa:device=hw=1.1

So the device hw:1,1 seems to be correct SPDIF output. Then you may try using device "iec958:CARD=Generic,DEV=1" instead of "hw:1,1" (equivalent to hw:CARD=Generic,DEV=1"). Instead of direct output to the driver, this device configuration will process the AES parameters passed by mplayer https://github.com/philipl/mplayer/...ff66e18544154f7483e3182/libao2/ao_alsa.c#L297 -> (https://github.com/alsa-project/alsa-lib/blob/master/src/conf/pcm/iec958.conf#L56-L74 + https://github.com/alsa-project/alsa-lib/blob/master/src/conf/cards/HDA-Intel.conf#L112-L142 ) - set non-audio SPDIF preamble via associated alsa controls provided by the soundcard driver. But it may not be necessary as your AVR seems to recognize the DTS stream correctly regardless the SPDIF preamble bit. But DTS may be handled differently than AC3 by your AVR, therefore setting correct AESx params is recommended.

Now once you find your device working OK for AC3/DTS stream, you can try to use it as slave for your a52 config - see e.g. https://forums.raspberrypi.com/viewtopic.php?t=172536#p1671540

Code: 
pcm.a52 {

    type a52

    slavepcm "iec958:{ AES0 0x06 AES1 0x82 AES2 0x00 AES3 0x00 CARD Generic DEV 1 }"

}

Note that the config above sets the AES0 0x06 (i.e. non-audio AC3) fixed as output from the a52 encoder is always ac3/nonaudio.

Then you can test your new multichannel PCM device "a52" e.g. with sox https://www.audiosciencereview.com/...to-sox-audio-tool-as-a-signal-generator.4242/ or aplay with some 6ch wav

While looking at your mplayer output - alsa-lib complains about "Unknown PCM hw:1,1,AES0=6". The reason for the complaint is that your hw device did not "consume" the AES0 parameter. If you use the iec958:... device, your alsa-lib configs will use the parameter (see the github.com/alsa-project/alsa-lib links in my previous post) and hw:XXX device used by the alsa iec958 plugin (it's all chained) will not receive any parameter - no complaints then.

You want to check which device is actually used by mplayer when the above command in your post is playing. It may not be hw:1,1. Check with command 'lsof /dev/snd/*', in my case (only pulseaudio active):

Code: 
pavel@precision:~$ lsof /dev/snd/*
lsof: WARNING: can't stat() tracefs file system /sys/kernel/debug/tracing
      Output information may be incomplete.
COMMAND    PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
pulseaudi 2928 pavel  mem    CHR 116,42           750 /dev/snd/pcmC2D0p
pulseaudi 2928 pavel   21u   CHR 116,44      0t0  752 /dev/snd/controlC2
pulseaudi 2928 pavel   27u   CHR 116,44      0t0  752 /dev/snd/controlC2
pulseaudi 2928 pavel   30u   CHR 116,35      0t0  680 /dev/snd/controlC0
pulseaudi 2928 pavel   36u   CHR 116,41      0t0  721 /dev/snd/controlC1
pulseaudi 2928 pavel   52u   CHR 116,42      0t0  750 /dev/snd/pcmC2D0p
pulseaudi 2928 pavel   68u   CHR 116,35      0t0  680 /dev/snd/controlC0

You want to see the command mplayer in your list, and some pcmCXDYp device will be open (lsof = list open files).

Hi,

This is what mpv does:
`[ao/alsa] opening device 'iec958:CARD=Generic,DEV=0' => 'iec958:CARD=Generic,DEV=0,AES0=6,AES1=130,AES2=0,AES3=2'`

However no luck getting mplayer to respect that neither 'iec958:CARD=Generic,DEV=1'. That what I meant when I said my 'aplay -l' output is inconsistent with my 'aplay -L' in regards to SPDIF. Ant this has been tested one million times with mplayer over the months with all possible syntax variations to no avail. It's one error message after another.

Will backup everything and try 'pcm.!default iec958' in my asound conf file.

Well then don't use DEV=1 but DEV=0 if that's what works. I do not know where DEV=1 (or hw:1,1) arose in your tests.

I would suggest not complicating the setup with redefining the "default" device, but consistently giving the alsa device you want.

Also, this mplayer usage is just for testing the DTS/AC3 device functionality. If mpv works better for you in this testing, use it instead.

No problem. I don't care about mplayer, particularly for 5.1 material where I rely on Kodi, mpv or vlc and so far the passthrough is working perfectly when pipewire is in control e.g. from Kodi config

Code: 
 <setting id="audiooutput.passthroughdevice">PIPEWIRE:alsa_output.pci-0000_00_14.2.iec958-stereo|Audio interne Stéréo numérique (IEC958)</setting>

I can imagine it get its config from wireplumber?

Code: 
$ cat .config/wireplumber/wireplumber.conf.d/51-alsa.conf

monitor.alsa.rules = [
 {
   matches = [
     {
       node.name = "~alsa_output.*"
     }
   ]
   actions = {
     update-props = {
       iec958.codecs = [ "PCM", "DTS", "AC3", "AAC" ]
     }
   }
 }
]

mpv config:

Code: 
audio-device=alsa/iec958:CARD=Generic,DEV=0
audio-spdif=ac3,dts,pcm
audio-channels=5.1

Mplayer has always be problematic either with DEV=1 or DEV=0 and when it fails, I'm not able to execute any other audio client for a few minutes, i.e. no sound.

My original understanding was that you were looking for a PCM-multichannel REW output through non-audio SPDIF. Now it looks like you are solving a general non-audio passthrough from your video players, a different goal.

For the REW goal no reason to involve PW/PA, IMO.

No. The conversation somehow deviated on this subject I presume while trying to setup alsa properly. Passthrough is already working well for all the players I currently use.
I still want REW to output to something else like alsa or hdmi audio.
As a matter of fact, I'm waiting for this HDMI to SPDIF converter today or tomorrow.

I agree, then it's either alsa or hdmi.

No luck with the hdmi to spdif converter. First, the audio interface isn't recognized on boot. One has to unplug it and replug it for pavucontrol to identify it. Then I can enable it.

So far on this hdmi device, system sounds work, passthrouh works, stereo works, mpv works using alsa, kodi works using pipewire, easyeffects works as well

REW OTOH can't make use of the 6 channels. It doesn't see them individually. Only stereo.

Returned the device, I bought it exclusively for REW to address each channel individually and was unable to manage that.

Well, spdif is a two-channel interface, why should the HDMI alsa card offer 6 channels? IIUC the SPDIF converter reports EDID with two channels (which is correct) and the HDMI driver correctly configures its alsa playback device to be 2ch.

The software DTS/AC3 encoder (i.e. 6ch PCM -> 2ch non-audio) plugin must be inserted into the alsa chain to create the 6ch PCM device for REW to see/use.

I don't know but it did. In pavucontrol 6 channels were visible and testable under the device HDMI/DP Surround 5.1. Was not working but the potential was there. I had to try it after I asked the question 3 times to no avail.

I read what you say, it's clear. But how to do it? And how to verify it's done afterwards?

I've read all the alsa manual but that was over 20 years ago. All my computers auto-configured but this very one.

Those surroundX.Y PCM devices are just hints, offered for HDMI config by the alsa config layer https://github.com/alsa-project/als...f1beae6/src/conf/cards/HDA-Intel.conf#L74-L79 . Potentially they may work, provided the underlying device supports the given number of channels. IMO the spdif converter will send a 2ch EDID, and the multichannel configs will not work.

You can check the EDID including audio params of the receiver with e.g. https://www.adamsdesk.com/posts/learn-to-read-edid-displayid-metadata-using-linux/

speaker-test -d -b 2000000 -c 6 -D"plug:{SLAVE=\"a52:1,'hw:1,1'\"}" -l 2
Click to expand...

That's a very unusual form of alsa device configuration, basically writing the config code into the device string. I would prefer to create .asoundrc with a52 device, as was linked in the discussions above. The best way is checking your PCM device params with aplay --dump-hw-params

Code: 
aplay --dump-hw-params -D your_device_name /dev/zero

In the end you want to avoid the plug plugin, so that no extra conversions are performed at the background.

Just a note - did I understand correctly that you had a native SPDIF output available? If so, then the HDMI->SPDIF converter would be superfluous.
