I’m contributing to librespot, which you might know as an open source client library for Spotify, and am writing you for your help to test changes to its JACK backend.
I’m no JACK user myself and trying to test for regressions in a patch that handles Spotify samples in 32-bit floats instead of 16-bit integers (for doing volume control and normalization). However, I'm not getting any sound and wondering if I am doing this right.
I’ve installed jackd2 1.9.12 on Raspian 10. I’ve got a working Alsa setup that outputs to an external DAC over I2S. I launched with “ jackd -dalsa -s -r 44100” and can hear a test tone playing when executing “jack_simple_client”. So far, so good.
However, I’m not getting any sound (or errors) when launching playing music with librespot launched with “—name test --verbose --backend jack audio --disable-audio-cache”. This is both on my branch of work  as it is on the untouched development branch .
Is there anything else I need to set up? Or better yet, could any librespot users chime in?
Thanking you in advance,
