Hi, Attached please find a patch against current sound-2.6 master that fixes audio anomalies and PulseAudio crashing by specifying LPIB method explicitly. Please apply. This patch is applicable to all 2.6.3x stable series. Best, -Dan
From 3f88418b6d4002115dc59cfcf13b00e121319f9c Mon Sep 17 00:00:00 2001 From: Daniel T Chen <crimsun@xxxxxxxxxx> Date: Sat, 29 May 2010 11:04:11 -0400 Subject: [PATCH] ALSA: hda: Use LPIB for a Shuttle device BugLink: https://launchpad.net/bugs/551949 Symptom: On the reporter's Shuttle device, using PulseAudio in Ubuntu 10.04 LTS results in "popping clicking" audio with the PA crashing shortly thereafter. Test case: Using Ubuntu 10.04 LTS (Linux 2.6.32.12), Linux 2.6.33, or Linux 2.6.34, adjust the HDA device's volume with PulseAudio. Resolution: add SSID for this machine to the position_fix quirk table, explicitly specifying the LPIB method.
