[alsa-devel] Firmware problem

Tue Dec 18 21:51:17 CET 2007

My user - yes there is one - of the aica sound driver on the Dreamcast
is having a problem with formware loading.

This is what he has sent me - anyone know what is wrong?

When loading snd-aica it gives:
[   55.119676] ALSA sound/sh/aica.c:641: ALSA Driver for Yamaha AICA Super Inter

then after like 15 or 20 seconds it will give:
FATAL: Error inserting snd_aica
(/lib/modules/2.6.24-rc4/kernel/sound/sh/snd-aica.ko): Unknown symbol
in module, or unknown parameter (see dmesg)

and dmesg gives this:
