Ok, thanks for testing.  Please send a summary of this regression to
alsa-devel@alsa-project.org, cc-ing Takashi Iwai <tiwai@suse.de> and
either me or this bug log so we can track it.

Be sure to mention:

 - steps to reproduce, what you expect versus what actually happens,
   and how that indicates a bug

 - which kernel versions you tried, and what happens with each

 - alsa-info.sh output, as an attachment

 - if you can make a recording of the strange sound available
   somewhere online, that would be ideal

 - whether you are able to bisect or test patches if needed

[1] may have more hints.

Thanks and good luck,
Jonathan
