From d78d7a90adf793943cc29a414b6f4364a700aad5 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 2 Mar 2009 14:26:25 +0100 Subject: [PATCH] ALSA: hda - Create "Analog Loopback" controls optionally Don't create "Analog Loopback" controls as default since these controls are usually more harmful than useful for normal users. Only created when "loopback = yes" hint is given.
