Subject: [25/28] ALSA: hda - Fix silent speaker output on Acer Aspire 6935
Date: Thu, 16 Feb 2012 16:55:59 -0800 [thread overview]
Message-ID: <20120217005537.359940911@linuxfoundation.org> (raw)
In-Reply-To: <20120217005609.GA17081@kroah.com>
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 02a237b24d57e2e2d5402c92549e9e792aa24359 upstream.
Since 3.2 kernel, the driver starts trying to assign the multi-io DACs
before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for
the speaker for a standard laptop setup like a HP, a speaker, a mic-in
and a line-in. However, on Acer Aspire 6935, it seems that the
speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it
results in silence by some reason, although the codec itself allows
the routing to DAC3/4.
As a workaround, the connection list of each pin is reduced to be
mapped to either only DAC1/2 or DAC3/4, so that the compatible
assignment as in kernel 3.1 is achieved.
