Hi, Attached please find a patch against sound-2.6 master HEAD specifying the LPIB quirk for an additional SSID to make capture work correctly in an installed distribution. This patch is applicable to 2.6.32, 2.6.33, and 2.6.34 stable trees (some with fuzz). Best, -Dan
From 8f04e364aa28b49cc9d33cb51ea9e6d53f5d02d8 Mon Sep 17 00:00:00 2001 From: Daniel T Chen <crimsun@xxxxxxxxxx> Date: Sat, 22 May 2010 12:05:41 -0400 Subject: [PATCH] ALSA: hda: Use LPIB for Acer Aspire 5110 BugLink: https://launchpad.net/bugs/583983 Symptom: on a significant number of hardware, booting from a live cd results in capture working correctly, but once the distribution is installed, booting from the install results in capture not working. Test case: boot from Ubuntu 10.04 LTS live cd; capture works correctly. Install to HD and reboot; capture does not work. Reproduced with 2.6.32 mainline build (vanilla kernel.org compile). Resolution: add SSID for Acer Aspire 5110 to the position_fix quirk table, explicitly specifying the LPIB method. I'll be sending additional patches for these SSIDs as bug reports are confirmed.
