[Bug 245062] Re: No sound in rhythmbox or any other application except through headphone jack

[Roland Meier]

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.
