This causes the issues described in <https://wiki.ubuntu.com/DebuggingSoundProblems/KarmicCaveats#Volume_range_anomalies> - The suggested workaround mitigates the problem after adding both lines (load-module module-udev-detect ignore_dB=1 and load-module module-alsa-sink control=PCM) but does not fix it completely. After the workaround the first 10% (guessed) of the volume control in the upper right corner keeps the PCM channel volume at the minimum, so there is no sound. Obviously only the lowest setting should set the PCM volume to 0. But this might be an Pulseaudio problem. * Lowering volume on the PCM channel to the minimum (which works) results in crackling noise. Probably notable observations: Detected codec differs from displayed codec in C-Media control panel in Windows XP and labeling on the codec chip on the mainboard (both say CMI9739A) >$ cat /proc/asound/cards > 0 [SI7012 ]: ICH - SiS SI7012 > SiS SI7012 with CMI9761A+ at irq 18 Using the generic driver for SIS 7012 on Windows XP available from <http://www.sis.com/download/> shows the same problem in Windows XP. Using the driver supplied by ASRock fixes the problem on Windows XP. I had reported this problem earlier against Ubuntu 8.10 in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/351042 - There might be some additional information, I have accidentially left out in this report.
