Micro en laptop

Listeros todos, alguien por ahí a podido configurar el micro en debian etch kernel 2.6.24-etchnhalf.1-486 en un ACER 4520? algo de info, cabe señalar que para que me funcione el audio he modificado /etc/modprobe.d/alsa-base y he agregado la siguiente linea: options snd-hda-intel model=acer position_fix=1

lspci | grep Audio
