From f9759301c68a274302e434daa135926c25ca51ca Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 16 May 2011 11:45:15 +0200 Subject: [PATCH] ALSA: hda - Don't create multiple same volume/boost controls in Cxt auto-parser Check the routing more exactly for avoiding the duplicated controls for the very same effect for multiple capture routes in Conexant auto-parser.
