Tengo instalado Woody 3.0r1 en una PC con motherboard M825 de 
PC-Chips que trae una placa de sonido VIA:

# lspci -v (truncado)
00:11.5 Multimedia audio controller: VIA Technologies, Inc. AC97 
Audio Controller (rev 50)
        Subsystem: VIA Technologies, Inc.: Unknown device 4161
        Flags: medium devsel, IRQ 5
        I/O ports at dc00 [size=256]
        Capabilities: [c0] Power Management version 2

No podia hacer que me funcione, entonces... siguiendo los 
consejos de gente de la lista me instale las ALSA, acabo de 
configurarlas y me encuentro con una sorpresa: Funciona desde el 
microfono hasta la lectora de CD, pero cuando quiero escuchar un 
mp3 (con mpg321 o mp3blaster por ejemplo) NO SE ESCUCHA NADA!
Ya subi el volumen con alsamixer.... y le saque el mute :)... y 
nada!
Esta es la salida de lsmod: 
# lsmod (truncado)
