I have unpluged my USB webcam witch has a mic in it and sound now works. I have been able to plug it back and reboot, sound still working.
But it has a little whistling distortion on some frequencies. (Analog Stereo Output) If I enable "Analog Surround 5.1 Output", that my soundcard and my speaker set support, the distortion get worst has I slide down the bass level. I mean really worst. Also, the bass level slider does not seems to "really" change the bass level. I have verified that my speaker set is correctly connected, it is. This message in dmesg make me think there is really a bug: [ 6.910015] hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... -- [karmic beta] no sound (HDA NVidia ALC883) https://bugs.launchpad.net/bugs/445012 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
