BTW, there is a newer version (which was actually applied) of this patchset in alsa-devel@, seems you were missing from CC on that one.
I didn't try that updated version yet, but I'm afraid I discovered some problem. I've switched from my Denon 1912 to the older Onkyo TX-SR605 and there is problem with multichannel playback. I've tried:
speaker-test -D hdmi:CARD=Generic,DEV=0 -c6 -r192000 -F S16_LE
speaker-test 1.0.25
Playback device is hdmi:CARD=Generic,DEV=0 Stream parameters are 192000Hz, S16_LE, 6 channels Using 16 octaves of pink noise Rate set to 192000Hz (requested 192000Hz) Buffer size range from 64 to 87360 Period size range from 32 to 43680 Using max buffer size 87360 Periods = 4 was set period_size = 17472 was set buffer_size = 87360 0 - Front Left 4 - Center 1 - Front Right 3 - Rear Right 2 - Rear Left 5 - LFE Time per period = 17.027360
But I can hear sound for rear right and rear left only :(
Is there anything more I can provide to help resolve this? Do you have any idea how we can resolve this?
According to the below the receiver has separate PCM SADs for 2-channel and multichannel playback. However, due to a radeon driver bug (see "[PATCH] drm/radeon/audio: fix missing multichannel PCM SAD in some cases", you were CCd) the multichannel SAD is lost and not shown below.
However, that is not (or at least should not be) the reason you are not getting audio. I suspect that the receiver does not support 192kHz multichannel audio (which would be indicated in the missing multichannel PCM SAD). Does it work with 48kHz or 96kHz? (TODO: refuse PCM playback in such cases)
If it does not work with 48kHz or 96kHz either, then we have a bug to solve :)
