It works in general. But mutes itself for small period of time in random intervals. I've looked at alsamixer and it shown what once in a while some of the parameters got to the lowest level and then returning to normal after some time. It is reproing on Speaker. But also Internal Mic Boost jumps from 100% to 0% and then back to 100%. BTW, when sound mutes on speaker, headphones are still working. So looks like alsamixer reports volumes correctly. I've also tried to purge pulseaudio and alsa-base packages and re-installing them again. But I was able to find workaround. Audio works just fine with old kernels. I've tried with 3.5.0-15 and 3.5.0-27. It works with both kernels. I've also tried newest kernel from next ubuntu version. 3.15.0-031500rc5 - audio is not working in new kernel. $ amixer -c 0 scontents > normal.txt SEE Attachment. $ amixer -c 0 scontents > muted.txt SEE Attachment. $ amixer -c 0 scontents > normalagain.txt SEE Attachment.
