No Sound when run under systemctl (audio branch) #48

Open martinglass opened 3 years ago

martinglass commented 3 years ago

The audio works when the server is run from the command line (python3 -m server.server) but it doesn't work when the server is run from systemctl

I tried the workaround, but alas it didn't work for me. Sound doesn't come out using systemctl, but it does come out when the server is run from the command line.

Nothing worked. Now, I've gone back to the original and rebooted. But I can't get sound out of bluetooth, even when it's connected using sudo bluetoothctl

I get this error when I try nanotts -i "Hello World" -p error: snd_pcm_writei: Broken pipe

I'm giving up for today!
