Subject: No more Intel HDA soundcard
Date: Sat, 28 Feb 2009 21:44:12 +0300 [thread overview]
Message-ID: <20090228184412.GA2333@x200.localdomain> (raw)
The following commit results in soundcard detection failing with -EBUSY
commit 34c25350acfc792747e861d1e36874abf7e73255
Author: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Remove old codec-probe limitation
Removed the old workaround to avoid the non-existing codec slot.
The current code should work without that workaround. If any,
we can add a quirk table.

I fixed up this (and got sound back) but suspect the following is not right.
