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 Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/920744 Title: alsa-driver: Cannot turn off internal speaker Intel HD Audio Status in “alsa-driver” package in Ubuntu: New Bug description: Hi, I use Lucid (10.04.3 LTS) on a Fujitsu Esprimo P5731 quadcore machine with Intel HD Audio with ALC633. I cannot turn off the internal speaker. There is no setting to turn it off, and it does not go off by itself when external speakers are connected, as with the Windows driver. The hardware setting is set to "Analog Stereo Output", and Output is set to "Internal Audio Analog Stereo". As a connection I can choose between headphones (then all speakers are off altogether), Analog Output and Analog Speakers. There is no difference between the latter two. Both the external speakers and the internal speaker sound at all times... Because of the poor quality of the internal speaker, that easily clips, and it being monophonic I want to turn it off, but there is seemingly no way to do this... alsa-base is 1.0.22.1+dfsg-0ubuntu3 ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: alsa-base 1.0.22.1+dfsg-0ubuntu3 ProcVersionSignature: Ubuntu 2.6.32-37.81-generic 2.6.32.49+drm33.21 Uname: Linux 2.6.32-37-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
