Public bug reported: I'm not sure if this is in alsa-driver, I think I'm using pulseaudio.
I don't hear anything I'm actually trying to record, just a loud high- pitched whine / squeal. Same result with arecord, Skype, gnome-sound- recorder, and "ubuntu-bug audio". lspci reports "00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)" ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: alsa-base 1.0.24+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic-pae 2.6.38.2 Uname: Linux 2.6.38-8-generic-pae i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
