Hi, I have the same problem, after upgrading to karmic (or after one of its normal updates - sorry) I had no sound output from the speakers from any application on my HP 550 laptop. Sound output via headphone works, and speakers were no problem before in jaunty either. I installed linux-backports-modules-alsa-karmic-generic with no effect. After installing the updates from https://launchpad.net/~ubuntu-audio-dev the headphones also stopped working with the default configuration (no model= parameter for the snd-hda-intel module). They now work again with "options snd-hda-intel model=basic" or "model=hp" in /etc/modprobe.d/alsa-base.conf . Most information should be in http://www.alsa-project.org/db/?f=1fad068e798f0fdc7563ba137172b7e4e9db9503 There are lots of similar bug messages here, none of which helped, so I picked the most similar one and added my current information. Please tell me how to help any further.
