After a routine upgrade it seems I don't have any sound devices any more.
More in detail:
* The driver for my card (RME HDSP MADI, snd_hdpsm) is loaded. * aplay -L tells me there is only the 'null' device. * (re)starting /etc/rc.d/alsa doesn't change things. * There is *no* /dev/pcm at all. * /sys/class/sound only has a link to a timer device. * No traces in dmesg or /var/log/messages of anything going wrong.
I suspect udev fails to do the right things.
* /etc/udev/rules.d is empty * /etc/udev/udev.conf contains only the line udev_log="err"
This is a professional studio and I'm expecting clients tomorrow at 09:00.
You could try udev from testing (I agree that probably udev is the culprit, though it has not been updated in core for some time). -t
