Subject: ALC268 - Driving mute led with GPIO
Date: Thu, 04 Feb 2010 18:44:48 +0200	[thread overview]
Message-ID: <4B6AF980.40207@pardus.org.tr> (raw)

Hi,

We have a laptop here (a local brand) which has a mute button with a LED. Currently the mute button works correctly but the
led is non-functional.

I've played through hda-analyzer and found out that it's enabled when you enable gpio3 and click out_dir. Clicking out_dir
again and again switches it on and off.

There's a mute led stuff in patch_sigmatel, sigmatel_spec has gpio_led and gpio_polarity information but alc_spec doesn't have.

How should we hook/patch that information into the codec?

I'll try to send the alsa-info output tomorrow.

Thanks.
Ozan
