Sorry, i find out that it's not a bug later. It's a configuration problem. I ask people in alsa project maillist and then check the configure file "/usr/share/alsa/alsa.conf" in ubuntu. The line "/usr/share/alsa/pulse.conf" makes the default config to be PulseAudio.
If this line removed, the alsamixer would act as normal. -- alsamixer can't recognize multi-channel audio card properly in ubuntu intrepid beta using default para https://bugs.launchpad.net/bugs/286805 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
