From f87498b65197f951899d8bbd99e5553227c41ec9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 21 Jan 2013 14:24:31 +0100 Subject: [PATCH] ALSA: hda - Check aamix-output paths from other DACs, too Many codecs provide routes to multiple output pins through an aamix widget, but most of them do it only from a single DAC. However, the current generic parser checks only the aamix paths from the original (directly bound) DACs through aamix NID, and miss the path: primary DAC -> aamix -> target out pin This patch adds a more check for the routes like the above.
