Is there a way to have output on both USB and also the HDMI? For me only one works at a time. It would be great to have both working so that I can put them on different zones. Thanks for all your help.
Currently volumio only supports one audio output at the same time
You can add multiple outputs to /etc/mpd.conf, for example I have a hifiberry and a USB iMic connected to my volumio.
type "alsa" name "Output0" device "hw:0,0" mixer_control "PCM" mixer_device "hw:0" mixer_index "0" dsd_usb "yes"
type "alsa" name "Output1" device "hw:1,0" mixer_control "PCM" mixer_device "hw:0" mixer_index "0" dsd_usb "yes"
I use the gmpc client rather than the web interface, which lets me enable and disable the outputs.
One issue is that the 2 outputs get out of sync, which is a shame, because my aim was to drive 2 sets of speakers in neighboring rooms. After a few minutes they have drifted far enough apart to sound bad. bugs.musicpd.org/print_bug_page.php?bug_id=2503
Yes, I know about this feature. But it is not implemented in Volumio since the Pi cannot simply handle it…
