Hello all,
I don't know if anyone can help me, or if this is even the right place to track down an issue I am facing. I have tried the developer, and filed a bug in github against the c code, but not getting any responses.
I am using an audio injector octo sound board on a raspberry pi 3. this sound board has 6 inputs and 8 outputs.
The issue I am facing is the audio channels appear to be randomly assigned each time speaker-test utility is ran.
My best guess at this point is there is a missing configuration in either the C driver or in the alsa configuration. I am hoping the latter hence my reaching out here.
My research has lead me to think that the missing information is related to the channel assignments are missing from the config, but I am out of my league in understanding the right way to go about this.
here is the driver if that is relevant at all https://github.com/raspberrypi/linux/blob/rpi-4.9.y/sound/soc/bcm/audioinjec...
I have configured per the device manufacturers instructions as follow
here is the asoundrc contents pcm.!default { # type hw # card 0 type plug slave.pcm "anyChannelCount" } ctl.!default { type hw card 0 } Here is the asound.conf contents pcm.!default { # type hw # card 0 type plug slave.pcm "anyChannelCount" } ctl.!default { type hw card 0 } pcm.anyChannelCount { type route slave.pcm "hw:0" slave.channels 8; ttable { 0.0 1 1.1 1 2.2 1 3.3 1 4.4 1 5.5 1 6.6 1 7.7 1 } } ctl.anyChannelCount { type hw; card 0; }
