Hi again, after I saw that I also have no sound in a fresh boot of some live CDs I sent this laptop to HP for a warranty repair, and they replaced the built-in speakers, so there probably was some hardware problem. Sorry...
Now maybe as a consequence of all my tries before I still have a problem: Immediately after booting I have no sound from any application, neither from speaker nor from headphone. All channels in alsamixer are unmuted and at max level. alsa-info.sh yields: http://www.alsa-project.org/db/?f=a8efaf3ded0b5b2aed83cffc15ed1d03b2cafc76 If I do a sudo alsa force-reload now, start alsamixer and unmute all channels and set all levels to max everything works as it should, and the result of alsa-info.sh now is: http://www.alsa-project.org/db/?f=f85ade26726c10bf8469b9d948b18ccd9a35a357 The difference that may cause the problem is in section "HDA-Intel Codec information": ... Node 0x03 [Audio Output] wcaps 0x441: Stereo Converter: stream=5, channel=0 ... After the force-reload the value after stream= changes to 0 (as in the other three occurences). The other remarkable difference is the line HDA Intel 0000:00:1b.0: PCI INT A disabled in the dmesg output the moment the force-reload is done (the other lines are the same in both configurations). Nothing changes between both load processes. I set model=hp in both cases. Trying probe_mask=1 didn't change anything. Something else I noticed is that I have two different hda-intel modules, one from a backports package, the other from the generic kernel package: $ find /lib/modules/2.6.31-17-generic/ | grep hda-intel|xargs ls -l -rw-r--r-- 1 root root 43192 2009-12-10 20:35 /lib/modules/2.6.31-17-generic/kernel/sound/pci/hda/snd-hda-intel.ko -rw-r--r-- 1 root root 43792 2009-12-11 07:29 /lib/modules/2.6.31-17-generic/updates/alsa/snd-hda-intel.ko (Probably that's irrelevant, since I booted the 2.6.31-14-generic kernel, which is th last to have only one module, and nothing changed). Sorry for the confusion with the defect hardware. Probably this is now a completely different problem, the headline doesn't fit any more. Maybe someone can help me here (what option can I chang to manually set this stream= setting to 0?), so we can close the issue completely. If you want me to I'll open a new case. -- HP550: No sound from laptop speakers, only from headphone in karmic https://bugs.launchpad.net/bugs/492303 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
