From dd203fa97bd5df18dbb0af5acf3e9a8beea33f74 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 10 Jan 2011 16:05:38 +0100 Subject: [PATCH] ALSA: virtuoso: remove non-working controls on Essence ST Deluxe On the Xonar Essence ST Deluxe, remove all mixer controls that would require I2C communication with the third DAC, which does not work because of an addressing conflict with the CS2000 chip.
