I have an Alienware m9700 w/ nVidia CK804 Ever since the move to pulseaudio my built-in mic has not been working. With many of the same issues stated above.
I was finally able to get it working by changing the V_REFOUT in alsamixer to 2.25v instead of High-Z (This almost acts like mute when set to 0v. When set to High-Z it almost as if there is so much interference that you don't hear the audio. I could turn the volume up all the way and I could here what I had recorded mixed in with the static. At 3.7v there was a little white noise in the background. At 2.25v everything was perfect) This got the mic functioning but only with the hardware configured as "Analog Stereo 5.1 output + analog stereo input" The problem with that is that everything played a bit fast and voices sounded as though the person was breathing helium. I set the hardware config in the pulseaudio settings to "Analog Stereo Duplex" And the following in alsamixer. Surround Jack Mode: Independent IEC958 Playback Source: AC-Link V_REFOUT: 2.25v For me it appears that it is a combination of settings between alsamixer and pulseaudio configurations. Everything works perfectly now. -- Sound capture (microphone) works on LiveCD, but don't work after installation https://bugs.launchpad.net/bugs/460351 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
