When I plug in external speakers into an audio jack on a Fujitsu s72220 laptop they are very quiet.

When I plug external speakers in: "Master" 45%->100% (unexpected, but doesn't harm), "Headphone" 0% -> 100% (expected and affects nothing anyway), "Speaker" on->off (also expected), "Speaker+LO" 100%->0% (that's the problem).

Something set "Speaker+LO" to 0% when it switches to headphones/lineout.

Perhaps this is a bug in alsa.

Sound card details:

Slot:   00:1b.0

Sett "switch = mute" and "volume = merge" in [Element Speaker+LO] in /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf.

This will be overwritten by a next update, a bug needs to be filed.
