Description Max 2012-07-19 22:19:32 UTC

Pulseaudio keeps my headphone volume to 100% (no headphones are plugged in, just speakers are used). When master volume is raised the speaker sound starts to clip/distort. I found out that this doesn't happen if headphone output is muted or set to a low volume.
I don't know if this behavior of pulseaudio is correct or it is caused by the ALSA driver (snd-hda-intel).

As a workaround I changed the "[Element Headphone]" section in /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf to:
switch = off
volume = off

I don't use headphones, so I don't care if they are not working anymore.
