Ubuntu
alsa-driver package

Sound settings keep changing...

Asked by gratefulfrog

on 11.04, running on an EEE PC 1201N, The sound settings as seen in the alsa mixer keep getting reset to silenced...

I have no idea why.

There is no way to increase sound using the F12 key, which is maxed out, or any volume controls - only via the alsa-mixer.

Is there any known 100% working sound setup for this relase+machine?

I am at the point of going back to Win7 despite my long long time support for ubunut.

All ideas welcome.

Thanks
bob

Hi!

Thanks for the tip. With that I have found a work around. Here it is for all :

This solution shows how to set the alsa-mixer for a EEE PC 1201N and how tol prevent google chat from playing with the volume levels.

Once implemented, both skype and google chat work properly. All other sound apps seem to work as well!

0. Close all applications, particularly any browsers with voice chat enabled, my problem was gmail chat.
1. Skype must be set to NOT adjust volume controls.
2. using the alsa-mixer, only one capture channel must be enabled. see attached screenshot.
3. close the alsa-mixer.
4. change the permission of the pulse audio config file for device-volumes to read only:
    $ chmod a-w ~/.pulse/*-device-volumes.tdb
5. This has fixed the problem for non-root applications, like browsers,
6. for gmail chat there is still one thing to do: edit the file:
    ~/.config/google-googletalkplugin/options
so that it contains the following line:
    audio-flags=1

I posted this to the forums as well, there you can see the screenshot. http://ubuntuforums.org/showthread.php?t=1813123

Thanks to all for their help!
