From 50c62f068ee67b5a0178855f502f4ea2ee931eed Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 28 Jul 2009 18:25:29 +0200 Subject: [PATCH] ALSA: hda - Don't create analog mixer for IDT92HD71bxx The analog mixer unit on IDT 92HD71Bxx codecs is almost useless since we use only the direct connections from DAC to pin. Remove the controls to avoid unneeded confusion as default now. This can be still back via "analog_mixer = 1" hint.
