I will try that next - an entirely new adventure for me. B.T.W. Thanks for your very patient support! I had not anticipated the ALSA v PULSE v WIRE v JAVA v HDMI driver v Linux version battles ahead just to get 24bit audio out of an HDMI port on the correct channels when I embarked on this...

Adding those simpleLogger options to $REW_HOME/roomeqwizard.vmoptions did not seem to have any effect. I wonder why "$REW/roomeqwizard.vmoptions" isn't being read. That would be more convenient than the command line. Do I need to set an option to refer to it? In any case, adding...

Oh. Setting "off" in GUI is not enough then. I'll have to dig. $ ls -l /dev/snd total 0 drwxr-xr-x 2 root root 60 Jan 23 21:30 by-id drwxr-xr-x 2 root root 120 Jan 23 21:30 by-path crw-rw----+ 1 root audio 116, 3 Jan 23 21:30 controlC0 crw-rw----+ 1 root audio 116, 5 Jan 23 21:30...

By HDMI format, I mean: $ aplay -v -D hw:vc4hdmi0 /dev/zero --dump-hw-params ... FORMAT: IEC958_SUBFRAME_LE ...

Only headphones: Headphones [plughw:2,0] Is this to do with the HDMI device expecting HDMI format frames? Or should plughw deal with that?

Well I don't particularly want PCM. But so far its the only listing of HDMI at all. I don't think the javasound is offering anything? $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0] Subdevices: 1/1...

In any case, setting the LD_LIBRARY_PATH fixes the csjsound issue that is the subject of this thread. So thanks. I think we can call this issue closed.

Thanks. Setting the path has fixed the csjsound error, and re-instated the PCM devices in REWs list of outputs (as expected since you explained the role of csjsound elsewhere). There is only one "PCM:HDMI" device listed though. I wonder why only one HDMI gets through csjsound? The REW log...

Update: I spoke too soon: Speaker-test appears to work via PW (default) - but in fact the channels are swapped around w.r.t. the raw ALSA device.

Why do you think that would help? Surely REW must either be adapting to PA/PW or going direct to ALSA devices like "speaker-test -D"? "Speak-test -D" works in all cases so far - whether I turn "HDMI-A-2" off or not in the PW GUI. If REW is direct to ALSA why can it not see what speaker-test...

Both HDMIs are listed in the GUI speaker control widget, and correctly control where REW and speaker-test sends output by default (for example). So both HDMI devices are "working", but somehow hidden from REW.

Update: A workaround is to set the desktop default to "HDMI-A-2". But this is nasty unless you want system sounds on that output as well!

Update: The list of REW outputs gets even smaller with JRE 17.0.9, rather than JRE 8. Now only the following outputs show up: Default device default [default] Headphones [plughw:2,0] No HDMI at all! Is there an rPi4/REW/OS/Desktop/Java combination that is known to work (including 2 x HDMI...
