Please drop this. This commit was reverted due to a regression later by the upstream commit 2078600b1f8fc68b02f6ebdda1759fb0c9f51afb ALSA: Revert "ALSA: hda/realtek - Avoid invalid COEFs for ALC271X" (which was already merged to Linus tree now). thanks, Takashi > > > >From d3c56568f43807135f2c2a09582a69f809f0d8b7 Mon Sep 17 00:00:00 2001 > From: Takashi Iwai <tiwai@xxxxxxx> > Date: Mon, 3 Feb 2014 09:56:13 +0100 > Subject: ALSA: hda/realtek - Avoid invalid COEFs for ALC271X > > From: Takashi Iwai <tiwai@xxxxxxx> > > commit d3c56568f43807135f2c2a09582a69f809f0d8b7 upstream. > > We've seen often problems after suspend/resume on Acer Aspire One > AO725 with ALC271X codec as reported in kernel bugzilla, and it turned > out that some COEFs doesn't work and triggers the codec communication > stall. > > Since these magic COEF setups are specific to ALC269VB for some PLL > configurations, the machine works even without these manual > adjustment.
