[Alsa-user] How to setup ALSA for SB32AWE, loopback device and extra MPU401 (090b12)

[Andreas S. <And...@gm...>]

For some reason, the loopback device (snd-seq-dummy) and the mpu401 
(snd-mpu401) do not show up in /proc/asound/sndtstat and aconnect -lio.
All I get are the OPL3, MPU401 and EMU800 of the SBAWE32.
Is there anything else to do to announce seq-dummy and mpu-401 to
the sequencer ? I don't use devfs, so there may be something missing
in /dev ? Is there something missing in the mpu-401 card driver module ?

This is what I've done so far : 
ls -w 60 /dev/snd
