I wonder whether it might be something related to sound power saving... I noticed there has been a change in the latest updates adding a "powersave_controller=N" into /etc/modprobe.d/alsa-base.conf. So first thing would be to see whether the bug is still reproducible with the latest updates (with that controller line in). If it is still there, try changing the powersave value in that file from 10 to 0 (disable powersaving). Then reboot and check the sound again. If it is gone then, we know at least it is related to that.
