Package: alsa-base
Version: 1.0.19.dfsg-3
Severity: grave
Justification: renders package unusable
When freshly booted, there is no /proc/asound/dev directory present.
The symlink /dev/snd is dangling. The rest of /proc/asound/
seems to be present:
~ [502]$ file /dev/snd
/dev/snd: broken symbolic link to `/proc/asound/dev'
~ [503]$ ls -lR /proc/asound

Then most alsa programs fail, e.g.
~ [504]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
aplay: device_list:226: control open (0): No such file or directory
aplay: device_list:226: control open (1): No such file or directory
The same behavior occurs if I boot into the previous kernel,
2.6.22-3, although everything worked with that kernel while Lenny was
still testing, so it shouldn't be hardware-related. My system is
up-to-date pure testing. I suppose udev might be involved. The current
version is 0.141-1.
Please let me know if further information would be useful.
Many thanks cgm
