After reading lots and lots of bug reports on the Internet, I tried to load, remove and/or blacklist pcspkr and/or snd-pcsp, to no avail. The speaker setting in alsamixer remains tied to internal and external speakers at the same time. When I disable the internal speaker, the externals go off, too.
After many fiddlings I found that plugging an empty (e.g. nothing soldered to it) headphone plug into the frontpanel headphone jack does mute the internal speaker, and not the external ones. But even then, disabling the pc speaker in alsamixer will turn off the external speaker. So I do have a bad workaround, but not a solution... Btw, Windows (XP, Vista, 7) do not have this problem at all... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/920744 Title: alsa-driver: Cannot turn off internal speaker Intel HD Audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/920744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
