Bug Description

I just spent a couple hours assisting a user (burningphantom1 on irc) get audible audio on his machine's speakers and headphones using Maverick (2.6.35) and the latest daily build of alsa-driver (2010-11-27). It seems that his machine's pci ssid, 0x17c04071, was added to the ALC883 quirk table (alc883_cfg_tbl[] in sound/pci/hda/patch_realtek.c) in commit 272a527c04 of sound-2.6.git (Mon May 14 11:00:38 2007 +0200, [ALSA] hda-codec - Fix ALC882/861VD codec support on some laptops). During the time of that commit, bios autoparsing was suboptimal, but the current driver (at least in 2.6.35 and newer) has much improved support. We've verified that playback, capture, and jack sense work correctly without the existing quirk entry, so we should just remove the one line for his machine's pci ssid.

Use bios auto-parsing instead of existing quirk entry

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!

This patch was applied to Maverick as part of an upstream stable update, therefore it doesn't require individual verification.
