[Voyage-linux] Voyage MPD & alsaequal

[Navas Abubacker]

Hi,

I am trying to get the equalizer with Voyage MPD on a alix3 box. But for
some reason the sound is breaking up,

I can see "alsamixer -D equal" working and when I debug the mpd I am getting
the output like this

alsa: Underrun on ALSA device "plug:plugequal"
alsa: Underrun on ALSA device "plug:plugequal"
alsa: Underrun on ALSA device "plug:plugequal"


for every alsa: Underrun on ALSA device "plug:plugequal" it is breaking up.

here are my configurations
