I have managed how to manually mute internal speaker without muting headphones: I dropped down to 0 the volume of Front/Surround/LFE (not muted them, otherwise also headphones will mute) and after un-mute the HP channel and rise volume.
A strange behaviour i noticed is that if I mute the master channel with alsamixer, and after un-mute it, the sound isn't restored. I must use the gnome volume applet to un-mute the soundcard to re-hear sounds (pulse issue?) -- Headphone jack sense doesn't work on MBP 17" unibody https://bugs.launchpad.net/bugs/437034 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
