From 3de5ff88773d9f106b668937da2f36c97801b332 Mon Sep 17 00:00:00 2001 From: Annie Liu Date: Fri, 8 Jun 2012 19:18:42 +0800 Subject: [PATCH] ALSA: hda - add support for HD-Audio CODECes of VIA HDMI GFX Cards This is patch supporting the CODECes of HD-Audio function of VIA GFX cards which support HDMI. For CODECes 0x9f80/0x9f81, which belong to VX900, since the hardware is not fully compliant to HD-Audio 1.3, simple_i*() is adopted temporarily.
