From 4902abcca2242127bf27606d6b55b1848e694da0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 23 May 2007 16:44:36 -0400 Subject: [PATCH] [PATCH] ALSA: hda-intel - Fix detection of audio codec on Toshiba A100 Some boards have the audio codec on slot #3 while the modem codec on slot #0. The driver should continue to probe the slots when no audio codec is found. This fixes the problem of no device on Toshiba A100 (and some other ATI SB450 devices).
