I think it might be something with updated ALSA kernel driver modules.
There have been a couple of others with mysterious "new" audio related
issues after kernel or alsa updates.
see
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1658
here is more on that ALSA report

Here are some MythTV reports

I think we should raise this over at ALSA.
