ALSA: ControlName.txt: Add 'Analogue' as a prefix for volume controls
Currently 'Playback Volume' is the correct way to express an analogue volume control. However, this control name has initialisation defaults applied when using 'alsactl restore' and in some cases this is not appropriate. An example would be a control that has a selection of 0db and -6dB of gain that is intended to set the fullscale ouput voltage of a DAC. The TI pcm512x family of DAcs have such a control. In this case the device/driver reset defaults are preferred. Signed-off-by: Howard Mitchell <hm@hmbedded.co.uk> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
