Subject: [PATCH] ALSA: HDA: Fix front mic on Dell Precision M6500
Date: Mon, 23 Aug 2010 21:03:11 +0200	[thread overview]
Message-ID: <4C72C5EF.6090600@canonical.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 381 bytes --]

The BIOS of Dell Precision M6500 lists both 0x0e and 0x11 as
front mics, and the driver only supports one front mic. This
commit adds a quirk for preferring node 0x11 (internal mic) to
node 0x0e (possibly docking station mic).
