thread 'cpal_alsa_out' panicked at 'capacity overflow'

[Sondeluz]

I am playing small tracks of audio (.mp3 and .wav files), with this code inside a thread, using the Rodio library:

let (_stream, stream_handle) = OutputStream::try_default().unwrap();
let sink = Sink::try_new(&stream_handle).unwrap();
let file = BufReader::new(File::open(path).unwrap());

let source = Decoder::new(file).unwrap();

sink.append(source);
  
sink.sleep_until_end();

While on my PC (x86_64) it works perfectly, attempting to run the same code in my raspberry pi zero (armv6) results in the following panic no matter what I do:

The pi zero is running raspbian/debian with alsa and libasound2-plugins working correctly.

I'm not really sure whether this should go to Rodio or here.

Please let me know if I can do anything to help!

I'm having the same issue on a pi zero. Any solution?

I'm having the same issue . Any solution?

Since cpal v0.17, the poll_descriptors_and_prepare_buffer function no longer operates on a Vec. Feel free to re-open if your issue remains.
