Totem does not respect global sound volume

[agro1986]

Binary package hint: totem

1) Open a media file (mp3, avi, etc) using totem and set the sound volume in totem to nonzero
2) Open the sound control panel (double click its icon on the top right)
3) In my system (VIA 8235 (Alsa mixer)) there are sliders for: Master, Headphone, PCM, and PC Speaker
4) Changing the "Master" slider, even muting it, won't affect totem
5) Changing the "Headphone" slider will affect Totem's volume

Expected behavior: Master volume should affect all applications.

I',m using dapper btw

Thanks for your bug report.

There is a post on the ALSA driver page for the VIA 8235 suggesting a module option to swap the "Headphone" and "Master" controls:

From http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=VIA&card=VIA+southbridge+AC97+audio.&chip=VIA82C686%2C+VIA8233%2C+VIA8233A%2C+VIA8235%2C+VIA8237&module=via82xx

"You can use the 'ac97_quirk'-option if your volume-level is very low (probably
due to some switching of the headphone and master controls). The options:
    ac97_quirk - AC'97 workaround for strange hardware (-1 = default)
                    -1 = default, don't override
                     0 = disable
                     1 = use headphone control as master
                     2 = swap headphone and master controls
                     3 = for AD1985, turn on OMS bit and use headphone"

This does not look like a Totem bug.

Does this module option fix the problem?

[agro1986 (agro1986)]

I would like to test it out. However, how do I pass the option?

After reading around, the file /etc/modprobe.d/alsa-base seems to be the one to tinker with... Here's the contents...

Which parts do I need to modify?

Thanks

Add this line to /etc/modprobe.d/options :

options snd-via82xx ac97_quirk=2

Works like a charm.

Now in the "volume control" applet there are only 3 entries in the "playback" tab: master, pcm, and pc speaker. The master slider works as expected.

This should be the default for my hardware (setting ac97_quirk=2). If there are any additional info that I should send so that making it default is possible, just drop a message here.

Thanks

(This corresponds to the 'swap_hp' name.)

Please attach the output from ``lspci -vn''.

[agro1986 (agro1986)]

This time lspci is run using sudo. Power management info is shown.
