Public bug reported:
Sound through speakers of my Lenovo Edge 11 laptop doesn't work in
Ubuntu 14.04 nor 12.04 nor 15.10 (LiveCD); I think it last worked in
10.04 or maybe even only in 8.04.
This was tested on a clean installation of 14.04 (64bit) onto a USB
stick, with all upgrades; but it neither works in my normal installation
(14.04 32bit) which was upgraded over the years. I also tried it on a
LiveCD boot of 15.10 (64bit), and speakers don't work there either.
The hardware appears to be fine though, because after booting, I
sometimes hear the short "drum roll" when the login screen comes up, but
no sound afterwards.
Headphones work fine; microphone appears to work fine as well (at least
the input level in Gnome mixer shows that it gets input).
I had already started to debug the speaker problem some months ago and
it looked like a problem with power saving mode for the sound chip. If
you have any hints how to debug this for real, I'm open for suggestions.
Also, is there any more info I can provide?
