Mono sound from Volumio

Hi Guys,

I wanted to change the audio to mono so I could use Volumio for one speaker. I found a thread on here detailing how to do it but I am a noob and I am not sure how to fully implement it. Anyone know the basic steps on what to do? Thanks!

Thread is here:

The method for doing it:
Don’t know if you found a solution but I found this :
Downmix stereo to mono

From … nux/155601

pcm.!default makemono

pcm.makemono {
type route
slave.pcm “hw:0”
ttable {
0.0 1 # in-channel 0, out-channel 0, 100% volume
1.0 1 # in-channel 1, out-channel 0, 100% volume


I don’t think changing mpd.conf is a good solution… because

  • Volumio will overwrite it
  • only mpd using service will be affected. No Spotify or other future streaming service.
    So creating a asound.conf file using ladspa plugin is better. But if you use software mixer the file is overwrite when saving this setting. Add your conf after that

Thanks for the response
Any chance you could dumb down your response a bit? I am new to the Raspberry Pi world and have limited experience with it. Sorry!

Change the setting in alsa using asound or alsaconf. there’s a comment thread here about doing a mono speaker with crossover from a hifiberry dac … rossover-/
