So after reading a bunch of different alsa-related solutions I tried to set my audio codec explicitly. For this I followed this manual: https://help.ubuntu.com/community/HdaIntelSoundHowto
Basically I added to the end of /etc/modprobe.d/alsa-base.conf this line: #======== options snd-hda-intel model=targa-2ch-dig #======== At the moment it seems like my problem was solved. Without plugged-in jack sound comes from built-in speakers, while with plugged jack sound comes to external amplifier. Here's a list with most of available model names: ======= http://www.mjmwired.net/kernel/Documentation/sound/alsa/HD-Audio-Models.txt ======= I picked mine for "Targa/MSI with 2-channel" based on my netbook name. So please try to find a proper model for your audio codec and hopefully your problem will be solved. But anyway I'm still disappointed why I didn't have this issue before 11.10 (10.04 - 11.04 worked perfectly regarding audio things). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874880 Title: Ubuntu 11.10 Headphone-To-Speaker Switching for Intel HDA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/874880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
