TTS - External bluetooth speaker

[sffranke]

Hi all, I am able to play audio on an external BT speaker from node red and from the console using aplay. I see no error message and the log just says its played.

[DEBUG:3846168] PicoTTSSentenceSpeaker: speaking -> ready
[DEBUG:3843747] APlayAudioPlayer: ['aplay', '-q']
[DEBUG:3843746] PicoTTSSentenceSpeaker: ready -> speaking
[DEBUG:3843621] PicoTTSSentenceSpeaker: ['pico2wave', '-w', '/tmp/tmpdmvsiyvo.wav', '-l', 'de-DE', 'wie lautet die Antwort auf die letzte aller Fragen?']
[INFO:3726233] quart.serving: 172.17.0.1:54346 POST /api/text-to-speech 1.1 200 31 2695711

Initiated through rhasspy audio is send to the audio jack. I have no idea what I can do.
Using the console
pico2wave --lang=de-DE --wave=/tmp/test.wav "Guten Morgen"; aplay -D default /tmp/test.wav
just works fine.
Anybody has a hint for me how to tell Rhasspy to use the external bluetooth speaker?

I see you use -D default when using aplay.
Try it without and see if it work, most probably it will not.
When using -D, you force a device. But you default device might actually not be the system default
