alsactl init: Mute CD Playback volume by default
PATCH 1/1 alsactl init: Mute CD Playback volume by default
The CD analog playback line is seldom used these days, as all modern players rip the CD and use the DAC on the sound card. In addition, it causes background hum on some machines. Therefore keep it muted by default.
