ok john i reset the driver to WASAPI and checked the exclusive box
Now the sweep noise sounds very strange a low kind of raspy noise nothing like before
is this normal ?

I retried to reset the sweep levels again thinking that may be the issue but no
the sweep sound is definitely distorted on all selested chanels

John Mulcahy said:
No, but it might be related to the FlexASIO buffer setting. You can set that to 4096 to see if it fixes it.

nope still very distorted

should i just go back to my previous FLEXASIO settings

John Mulcahy · Feb 23, 2023

OK, thanks for your patience. Could try unchecking the exclusive boxes to see if it works for normal WASAPI, then sure go back to what worked. Perhaps the last log you captured has some clues for Pavel.

works fine now with NO box not checked and the buffer set to 1024

OK John now that all 8 channels are working what do you think of my REW grafts
Any and all comments will be great Thanks again for all you help

Fine. But measurements 2,5,9 have negative polarity.

Unfortunately the attached log files in post https://www.avnirvana.com/threads/rew-excl-help.11756/post-88899 and https://www.avnirvana.com/threads/rew-excl-help.11756/post-88884 are the same file, from the previous non-exclusive test.

I just checked all the wiring for the amps possessor and all speakers for polarity issues
all are correct
What else can it be that your seeing in the grafts

John have you had the time to coment on my rew grafts ?

John Mulcahy · Feb 25, 2023

Yes, looks like you have a very well treated listening space, decay times from100 Hz up are very uniform. I'd be inclined to raise the level of the subs a few dB, but otherwise looks good.

The polarity changes are a bit odd, in measurement 2 RF is inverted but in measurement 11 it isn't, not sure what to say about that.

Could you have another go at a FlexASIO log to try and capture the WASAPI exclusive behaviour for Pavel? You'd need to make a fresh empty FlexASIO.log file in your users folder and go through the process of selecting WASAPI with the exclusive boxes checked then go make one measurement attempt. You can make that measurement at a low level so it isn't too unpleasant to hear, or just turn down the receiver volume.

OK john thanks for you reply and comments on my REW Grafts
I don't know why the inverted measurement shows up that way because all the wiring is correct
Yes i agree i need to boost the lower end up about 3-4 db and yes the room is treated with GIK panels
I just deleted all the old FLEXASIO files and went back to FlexASIO using the WINDOWS WASAPI driver and
checking the two Exclusive boxes AND NOW everything works fine like before (not checking the boxes)
I don't know it did not work before??
I also went back in and checked JAVA EXCL and NO GOOD no test sounds at all
Java will work aslo fine using the AVM70 "HD audio for display audio" driver
So i guess i'm all set now with the two
I wish i could test my 4 ATMOS ceiling channels the same way while using the FLEXASIO

Thanks again for all your help and for designing REW fo everone

john
How do you see the Polarity differance using REW ?How do i check for if is correct or not?
I do not see the differance between the #2 and #11 grafts propably because i
don"t know where to look or what i"m supsossed to be looking at

OK here we go again, NOW I just tried to make another couple of scans using FlexASIO with the Exective
boxes checked and when I try to scan I get a lot of static noise at the beginning of the ramp up noise
I don't get this static noise when checking levels only when I try to do a scan.
Maybe Pavel can help with this?
I'm attaching two files I hope one of them tells the story as to why this happening.
so i guess i will un check the executive boxes and leave it that way at least to a correction is found.
Let me know if i can be of further help getting this solved
if this is all you need

The flexasio log shows the wasapi exclusive playback params before the read/write methods start being called:

If you set the impulse graph axis to percent you can see the polarity. Here is measurement 2:

and here is 11:

Can it be a channel mask issue given the reported behaviour of not working with WASAPI exclusive on FlexASIO, then later working OK, then not working again?

sm52 · Feb 26, 2023

Maybe this is not a problem with the iron part of the equipment. But it could be a software issue. I wrote about a strange polarity reversal when changing the outputs of the same selected output device. https://www.avnirvana.com/threads/v5-20-14-early-access-build.11154/post-88732

Who knows what is going on there. The csjsound debug log would most likely show more.

thanks john for showing me this
I found out why they are both different Its because I was moving the RF speaker and on messurement 1 I must of switched the wires on the speaker and when I moved it back ( # 11) I hooked up the wires correctly MY BAG
I have a question though, this is a graft that to me looks funny. Its seens to show neither pos or neg? I have 4 channels that look like this and I know there wired correctly. Does this indicate that there is something wrong ?

I don't know how to get you this needed debug file
Can you or someone explain to me how ? Maybe its too tech for me IF so i will have to get someone to team
in and help.

Look at where the graph reaches 100% to get a good indication of polarity, that plot looks to be inverted.
