[alsa-devel] [PATCH] alsa-lib: Conf: Fix channels of ICE1712 to 10/12
I know this issue has been brought up before, without resolution. Basically PulseAudio cannot open cards such as M-Audio 2496 and M-Audio Delta 1010LT because it does not try to open "front" with 10 channels, only with 2.
I think it is reasonable to assume that a front:x stream should be able to open with 2 channels only, therefore I'm proposing this fix, and I'm applying it to Ubuntu as well, unless you have a better idea.

I applied your change to our git repo . Perhaps we find a better solution in future.

But front device cannot be used for capture
I have used David 's alsamixertest to verify that using "front" device of HDA intel for playback/capture , the softvol plugin "PCM Playback Volume affect the dB scale
