I have this same problem on my Thinkpad R50e laptop, with the Intel 82801DB sound card (it uses the module snd-intel8x0) in Ubuntu 7.04. Everything looks fine with the sound, and xmms starts playing the songs fine and doesn't complain anything, but the sound is inaudible. I have tried to use OSS instead by using the OSS plugin in xmms and somehow I managed to use the /dev/dsp device instead of using alsa, and xmms played the song without errors but the sound couldn't be heard.
So I was thinking that maybe the ubuntu kernel developers had done something wrong with the 2.6.20-15-generic, and then I got the vanilla 2.6.19 kernel source, compiled it with the config I had before (which worked fine on my previous mandriva distro) and the problem continued! And this 2.6.19 kernel has everything related to my soundcard compiled in, so it is not an issue with ubuntu loading the modules with wrong options. After using the same old working kernel I had in this machine and getting the same problem with the inaudible sound, I don't know what else to do! I even loaded the mandriva 2006 live cd to check that it was not my soundcard failure, but the sound worked fine. So it looks like Ubuntu 7.04 mutes the sound somehow and fools alsamixer to think that the sound is not muted! I don't know what to do anymore. This is the first time I send a bug report and I am willing to perform any tests I am told to do. -- [Feisty] Very low volume on Toshiba satellite a100-155 https://bugs.launchpad.net/bugs/93859 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
