One time I was up early in the morning and heard my computer making a bit of a noise so I thought I'd wake it up and see what was going on. I checked in the process viewer and realised straight away that it was the cron job happening and that was fine but I also saw coreaudiod in red and not responding.

This was a root process that starts at launch time so I couldn't restart it without rebooting (I think). I wondered what it was and I found a website that says this is a new thing in Tiger that helps out coreaudio. I restarted my machine and it was ok but now tonight, it's hung up again. I don't think it's affecting anything but I don't know why it's crashing as there doesn't seem to be any logs for it.

I have a suspicion about Videolan Client but I'm not sure. Anyone else getting this problem?

do you have any audio software or drivers installed?

Detour?

Does your machine still output audio when that process is hung?

VLC has been giving me problems also.... even the Tiger alpha.

I don't have any audio software or drivers installed or detour. I do have a set of usb headphones that once caused OS X to disable my usb port on my keyboard because it was drawing too much power but they normally work fine and I didn't use them when the crash happened. I used VLC to play a VOB file on both days it happened. I'll need to restart and watch the process viewer while playing the same files.

I was surprised that it did but yes it still outputs audio when coreaudiod is hung. I don't exactly know what it does.

VLC always changes my audio output (iMic) to 2channels/8bit. When I close VLC I always need to change it back to 16 or 20 bit. Very annoying.

After checking my system log, it seems that coreaudiod crashed just before the cron started at about 3:15 am. I don't think I was using my machine at that time. I tried VLC again with the same files and it seemed to be ok. Does anyone know how to restart a root process like coreaudiod without rebooting?

Ok, I've discovered that if you just quit the process, it asks to authenticate and the daemon reboots fine.
