Got a problem with my system running under mdev. When I try to play CDs (with aqualung feeding into PulseAudio), no sound comes out. However, when I listen to an audio section from a newspaper page such as www.tagesschau.de (no idea what audio format) it works. Clearly this is something to do with mdev. I had a look at the devices in /dev, searching for those in group audio. Under udev, I find the following as device nodes: adsp audio dsp mixer mixer1 sequencer sequencer2. Under mdev, all of these bar one are symlinks into the real nodes in a subdirectory. The odd man out is mixer1 which is a device node, but with owner/group begin root/root (rather than root/audio). Can anybody suggest any fix, or further areas of exploration? Thanks! -- Alan Mackenzie (Nuremberg, Germany).
