From 47fd830acf0b6b5bc75db55d0f2cc64f59a23b5f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 10 Aug 2007 17:11:07 +0200 Subject: [ALSA] hda-codec - add snd_hda_codec_stereo() function Added snd_hda_codec_amp_stereo() function that changes both of stereo channels with the same mask and value bits. It simplifies most of amp-handling codes.
