[linux-audio-user] Gentoo: Alsa/Snd-usb-audio not working anymore

Hello!

I've already posted this topic to the official Gentoo forums, but nobody
was able to help me.

I've successfully run my Maya 44 USB together with the snd-usb-audio
module for more than a year. But after the last update of ALSA some
strange things are going on. "Alsaconf" doesn't find the USB soundcard
although snd-usb-audio is loaded. mpg123 gives the following error:

=== Could not load default driver and no driver specified in config
file. Exiting.

jackd prints the following errors:

Code:
JACK compiled with System V SHM support.
loading driver ..
apparent rate = 48000
creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|hwmon|hwmeter|-|32bit
control device hw:0
ALSA: Cannot open PCM device alsa_pcm for playback. Falling back to
capture-only mode
cannot load driver module alsa

Mplayer is able to play media through SDL (I've no idea what this
means), but complains about missing ALSA:

[AO OSS] audio_setup: Kann Audiogerät /dev/dsp nicht öffnen: No such
file or directory
alsa-init: using device default
alsa-init: playback open error: No such file or directory
[AO ESD] esd_open_sound fehlgeschlagen: Connection refused
[JACK] cannot open server
[AO SDL] Samplerate: 44100Hz Kanäle: Stereo Format s16le
AO: [sdl] 44100Hz 2ch s16le (2 bytes per sample)
Video: kein Video
Starte Wiedergabe...

That means that ALSA is obviously not usable. Some more infos:
