no audio drivers are available

[AlexINSERM]

Hello and thank you for your package. In love in my youth with the English band 808State, I immediately wanted to try it but I have the following error message: Erreur dans play.default(x, rate, ...) : no audio drivers are available Can you help me please ?

This seems like an issue with the audio package, not tr808r.

I assume that you have an audio device on your system, and can hear other sounds on your computer.

Can you see if this code works for you?

audio::play(sin(1:10000/20))

If that code fails, then it means that you have a problem with the audio package detecing your system. This may be a known problem for your system or you may have to report the issue to the audio developers.

Could you post the output of sessionInfo() and Sys.info() on your system?

I get the same issue on Ubuntu 20.04 with R 4.2.0

Hopefully this helps:

> tr808()
BPM: 96  FPS: 25.6
SPACE to play/pause
'c' to clear current pattern
's' to save tr808 state (load with 'state = ...' argument)
't' to copy tweetable text to clipboard/print to console
'1'-'8' to toggle pattern for playback
SHIFT + '1'-'8' to jump immediately to this pattern (usually best when PAUSED)
+/- Up/Down to adjust BPM
Starting Event Loop. Press ESC in window to quit. Waiting for input
