I’m trying to get Rhasspy to use the dmix so I can also have mopidy working (mopidy doesn’t release the audio device when it finishes playing a sound). But Rhasspy refuses to work with dmix.
These are the settings.
This works from the command line.
aplay -D dmix:CARD=Device_1,DEV=0 piano2.wav -q -t wav
The speaker is a cheap usb speaker, but it seems like that’s not too important here since it works from the command line.
