[2545A25, Conexant CX20582 (Pebble), Speaker, Internal] No sound at all through speakers on Lenovo Edge 11

[Oliver Gerlich]

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?

you have to file upstream report if it is a regression
