I have also had the same problem. I have two soundcards. In feisty, the sound worked, in gutsy not.
aplay returned following: ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'defaults.pcm.dmix.device' ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:3982:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default So I decided to delete my configuration files: rm .asoundrc .asoundrc.asoundconf The sound immediatelly started working! But I would prefer if the files were deleted by the upgrade script rather than struggling myself to find the reason. Just to give you more information, here is the diff between my correctly working gutsy (left) and the original feisty configuration file. In the older alsa version, the definitions like "defaults.pcm.device" were probably not yet mandatory: 15,21c15,17 < defaults.pcm.dmix.max_periods 0 < defaults.pcm.dmix.rate 48000 < defaults.pcm.dmix.format S16_LE < defaults.pcm.dmix.card defaults.pcm.card < defaults.pcm.dmix.device defaults.pcm.device < defaults.pcm.dsnoop.card defaults.pcm.card < defaults.pcm.dsnoop.device defaults.pcm.device --- > defaults.pcm.dmix_max_periods 0 > defaults.pcm.dmix_rate 48000 > defaults.pcm.dmix_format S16 54,56d49 < defaults.namehint.showall off < defaults.namehint.basic on < defaults.namehint.extended off -- no sound since upgrade to gutsy with pci id 10b9:5461 https://bugs.launchpad.net/bugs/139892 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
