[LAU] hdsp, mpd and lyrcing

[Andrew Gaydenko]

Hi!

For "lirc-ized" playing back I use mpd CLI client. As far as hdsp driver 
hasn't common "Master Volume" (or such) alsa control, I use mpd's "software" 
volume leveling, so lirc commands are directed to CLI mpd client.

To have some reserve in volume I set amplifier's volume regulator higher than, 
say, is needed at current moment. As a result I have software level noticeably 
below 100%. I suppose such software volume regulating eats samples resolution 
(and, at least theoretically, sometimes I have, say, 12-13 bits rather 16). 

Am I right?

If "yes" - are there ways to use lirc to set a volume level more directly 
communicating with hdsp driver via CLI? Will such way keep sample accuracy?
