Hi Marco
maybe this topic is a bit outdated, but still, when using the current hg code of the kernel module together with 2.6.24 (stable), I can't get any sound :(
Interesting. I've had another user report getting sound out of the latest hg tree with an ALC268 both with test mode and the "auto" mode. Our continued failure to get anything out of your laptop over the last few months makes me suspect that there's some other non-standard thing (external to the ALC268 codec) linked to the sound system in your laptop which prevents audio unless activated. Takashi, what's your take on this?
Hard to say... I still think it's either GPIO or EAPD except for very stupid things like the hardware-volume control via laptop keys (e.g. Thinkpad has independent volume controls and you have to unmute it via a button properly). Marco, did you test all combinations of GPIO and EAPD?
On other earlier ALC codecs, some device require COEF setups. This might be worth to try for ALC268 if the above is all checked.
