From 69a07304d52cc1080fa650c4ba7a82eed3cd143c Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 10 Dec 2007 12:28:52 +0100 Subject: [PATCH] [ALSA] cmipci: disable 'Modem' control on version 39 or newer chips On version 39 or newer chips, we better remove the 'Modem' control because this register bit now mutes the front channels of the multichannel stream.
