This sounds like an issue similar to one I had recently:

http://lists.mythtv.org/pipermail/mythtv-users/2022-June/409756.html

I managed to get it working (not because I have any particular insight
into this - more by luck - see the email), but I came to the
conclusion that there is a bug either in MythTV or the kernel/alsa
functionality that reports audio functionality.

Cheers,
Justin.
