[Voyage-linux] mpd warnings about "config option was not recognized" when options are valid

[Mark Schlegel]

I'm using Voyage 0.8.5 fully updated to today (9/15/2012) and each time 
I boot Voyage mpd, I see a group of warnings in /var/log/mpd/mpd.log 
that don't make sense to me:

Sep 15 07:49 : config: option 'mixer_device' on line 206 was not recognized
Sep 15 07:49 : config: option 'mixer_control' on line 207 was not recognized
Sep 15 07:49 : config: option 'mixer_index' on line 208 was not recognized

When I check those lines (206-208) in /etc/mpd.conf I have:

         mixer_device    "default"       # optional
         mixer_control   "PCM"           # optional
         mixer_index     "0"             # optional

which to me looks like completely correct values for those options. So 
why is mpd complaining about those. BTW, the mpd is working so it's 
nothing fatal, I just like to have the system working correctly.

the entire stanza is for this audio_output:

audio_output {
         type            "alsa"
#       name            "My ALSA Device"
         name            "Stello DAC sw mixer"
         device          "hw:0,0"        # optional
#       format          "44100:16:2"    # optional
         mixer_device    "default"       # optional
         mixer_control   "PCM"           # optional
         mixer_index     "0"             # optional
         # allow volume to change remotely via mixer_type
         mixer_type      "software"
}

Since all three of those are the default settings I suppose I could 
remove them but I was wanting them shown explicitly. Does mpd have some 
problem with the default value being set redundantly like this?  Maybe 
"was not recognized" is kind of the programmer's dumb way of really 
meaning that the setting had no effect because it was already the default?
