Title:
[Lenovo ThinkPad X61s] Speaker volume mutes itself in random intervals
after upgrade to 14.04
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I've upgraded from ubuntu 13.10 and sound stopped working properly. 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.
