[alsa-devel] [PATCH] Acer aspire 3830TG and Conexant 506c/20588

[David Henningsson]

The new Conexant 5066 auto-parser is barely finished and already we 
might need a quirk system for it...

Anyway, in this bug, the internal speaker is not working (and was not 
working before the auto-parser either). I'm attaching two patches that 
are quite simple, and at least the first one (add ID 506c) I think 
should be applied right away.

The problem: The internal speaker is at node 0x1f and you need to turn 
on EAPD on node 0x1b for the speaker to sound. Now I'm not sure how to 
fix this in the best way. An "init verb" quirk, or a "use EAPD from this 
pin" quirk? Try to copy-paste realtek's quirk system, and if so, 
refactor it into hda_codec.c, or write something new?

What are your ideas?
