I don't exactly know the implications of failing multiple stream synchronisation (is that something we commonly use?), or the implications of writing to a register that is "Reserved" in the HDA Spec (can there be crazy vendor magic in there we're unwillingly messing with?). Perhaps someone else knows more and can tell if this is something that is actually important. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic --------------050206000100040505070002 Content-Type: text/x-patch; name="0001-ALSA-HDA-Correct-address-for-SYNC-register.patch" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename*0="0001-ALSA-HDA-Correct-address-for-SYNC-register.patch" >>From d7ade361618ee99b89a82b84b035d345ef7a1bd9 Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Wed, 16 Mar 2011 11:35:11 +0100 Subject: [PATCH] ALSA: HDA: Correct address for SYNC register The SSYNC register is located at address 0x38 according to the HDA specification.
