Message-ID: <20090420184024.GA10155@dose.home.local> Date: Mon, 20 Apr 2009 20:40:24 +0200 From: Tino Keitel <tino.keitel@...ei.de> To: linux-kernel@...r.kernel.org, alsa-devel@...a-project.org, tiwai@...e.de Subject: 2.6.29 regression: left audio channel broken after resume from suspend with Intel HDA Hi, since 2.6.29 and also with 2.6.29.1 the left audio channel of the digital output of my Mac mini Core 2 Duo is noisy. This didn't happen with 2.6.28. Unloading snd-hda-intel and reloading it does fix the noisy sound. This happened with some older versions of the Linux kernel (with an older Mac mini Core Duo, I don't remeber which kernel version), but got fixed at some point. Now it happens again with 2.6.29. Here is the dmesg output for the sound hardware: HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 HDA Intel 0000:00:1b.0: setting latency timer to 64 hda_codec: STAC922x, Apple subsys_id=100 input: HDA Intel Line In at Ext Left Jack as /class/input/input18 input: HDA Intel Mic at Ext Left Jack as /class/input/input19 input: HDA Intel HP Out at Ext Left Jack as /class/input/input20 Any hints what I could try to fix this, maybe some commit that I should try to revert?
