From 485100706b4b397f8072c756839878f634e21f85 Mon Sep 17 00:00:00 2001 From: Trent Piepho <xyzzy@speakeasy.org> Date: Wed, 25 Jul 2007 18:39:59 +0200 Subject: [ALSA] ca0106: power down SPI DAC channels when not in use For cards with an SPI DAC (SB Live 24-bit / Audigy SE), power down channels 0-2 when not in use. They are powered up on PCM open and down again on PCM close. Channel 4 (== Front) is not powered down, as it is used for capture feedback. Powering it down would effectively kill line in pass-through.
