It appears that recent changes on ALSA resulted on Bay Trail and Cherry Trail devices sound to stop working:
The most recent release of alsa-lib was released on November, 28, this year. Mentions of the patch was on December 3, so I doubt that the patch is present now, excluding the fact that I receive a similar error (running on a Cherry Trail CPU). I was wondering what kind of action is necessary for instances like these? Do we just wait till the upstream patches reach our end?
Thanks, and a Happy New Year!~
