Hi,

Attached are two patches against alsa-utils.git HEAD that create an intel8x0 init db file for ICH4. This is necessary from bug reports in Debian and Ubuntu that state that External Amplifier must be muted to have audible (analog) playback by default on the Sony VAIO VGN-T350P.

Thanks. But, basically it means that a quirk in the driver is needed to revert the EAPD switch. Could you check whether ac97_quirk=inv_eapd module option for snd-intel8x0 works?
