[PATCH 3.12 014/197] ALSA: hda - Fix digital mic on Acer Aspire 3830TG

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Takashi Iwai <tiwai@xxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit ff50479ad61069f3ee14863225aebe36d598e93e upstream.

Acer Aspire 3830TG with CX20588 codec has a digital built-in mic that
has the same problem like many others, the inverted signal in stereo.
Apply the same fixup to this machine, too.
