Speakers do not mute when using headphones

[Marián Bača]

Binary package hint: pulseaudio

Hello,
I am using Ubuntu Maverick beta. Sounds works fine, but when I plug headphones, some problems appear. I open some audio file . Sound works fine, but when I plug headphones, tray icon shows, that sound is muted and also headphones and speakers are muted. When I click on Unmute, sound is streaming through headphones and speakers synchronous.

Thanks, Majo

Yeah, I can confirm that. The VIA drivers send out a control event from the driver, which mutes the "Front Playback Switch". This in turn confuses PulseAudio, who thinks you muted everything and so it tries to be helpful by muting everything else for you as well.

@David Henningsson, is this a duplicate of bug #565685 (which also covers a jack-sense problem with an Asus K50IJ mainboard)?

[David Henningsson (diwic)]

@Gary M, yes, it seems safe to mark as a duplicate - thanks for noticing!
Btw, the instructions at https://wiki.ubuntu.com/Audio/SameHardware can aid in figuring out whether a bug is a duplicate or not.
