From b75e53f09212f12369156710e84d1cbf115113cd Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 10 May 2007 16:56:09 +0200 Subject: [PATCH] [ALSA] hda-codec - Make the mixer capability check more robust In some cases, mixer elements return -EINVAL because it couldn't obtain proper amp_cap bits. The patch improves the robustness, trying the amp_cap query again in such a case.
