[Bug 44412] Volume broken on hda intel on Sony Vaio laptop

[John Leach]

Public bug reported:

This is on a i386 Dapper system updated from repositories each day.

A few weeks ago my sound stopped working on my Sony Vaio VGN-A397XP.

Programs (such as totem, mpg123, beep-media-player) would happily sit
there playing the audio, but no sound would make it out of the built-in
speakers (or from headphones).

I tried *every* volume control (and mute switch) in gnome-volume-
control, gnome-alsa-mixer, alsamixergui and alsamixer console but with
no luck.

Then, a few days later a noticed a "speaker" volume control (in all the
aforementioned volume tools iirc), which, when turned up, fixed my audio
problems.  I was pretty sure this particular control had not been there
before.

Now, a few more days later it has disappeared again and my audio is
broken in the same way.

This is rather puzzling, but due to it's dis/appearance in all alsa apps
I'm assuming it's an alsa issue.

Note: the original reporter indicated the bug was in package 'alsa';
however, that package was not published in Ubuntu.

** Affects: linux-source-2.6.15 (Ubuntu)
