[alsa-devel] Regarding Sound on Acer Aspire 6935G

[Emilio López]

Well, I finally got it to work. I had to triplicate the
"spec->autocfg.hp_pins", I don't know why, but it made it work.

Here is the patch:

From: Emilio López <buhitoescolar at gmail.com>

Fix recording from internal microphone, make jack sensing mute all the
internal speakers.
