** Summary changed: - No sound on Thinkpad X60 since last update + No way to reset ALSA state from GUI
** Description changed: - Hi, since I updated my ubuntu the last time, I have no sound on my - Thinkpad X60. Referring to lspci it is a Intel Corporation 82801G sound - card. It already worked with Herd5. + There is no way to reset the ALSA state from the mixer applet. - *edit* if i start for example gedit i get the following messages: - ALSA lib pcm_dmix.c:876:(snd_pcm_dmix_open) unable to initialize slave - ALSA lib pcm_direct.c:867:(snd_pcm_direct_initialize_slave) snd_pcm_hw_params_an + Several users have found that they lose sound, and that the problem + turns out to be an asound.state file which does not work for their + hardware. It has not been established how the file came to be corrupt or + whether the problem was caused by upgrades to newer versions which did + not handle the file as written by the previous version. It has not been + established what aspect of the asound.state files caused the problem. + But several approaches can fix the problem: - *edit2* oh and I have the beep inside gnome-terminal when using - completion etc. I'm also able to mute this sound when I turn off sound. + 1. Removing the ALSA modules, deleting the asound.state file, and + reloading the modules. This is difficult to do for non-expert users, + because applications such as the Gnome mixer and volume control can be + using the modules, preventing their unloading. + + 2. Removing the ALSA modules, and editing the asound.state to an + ultra-minimal state that reflects only the primary card, and reloading + the modules. + + 3. Invoking the alsa-utils "reset" option. On Ubuntu, typing this fixes + the problem for Intel sound cards: + + /etc/init.d/alsa-utils reset Intel + + The latter option is thought to be best, because it doesn't require + unloading and reloading modules. + + It would be very useful to be able to invoke that "reset" command from + the GUI Gnome mixer applet, which is why this bug has been filed on + that. ** Tags added: sound -- No way to reset ALSA state from GUI https://bugs.launchpad.net/bugs/95940 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
