Panicked at 'Can't set rate.' when using jack/alsa with a sample rate other than 44100

[wasolili]

I'm running on Linux using Jack for audio and using the default ALSA -> JACK plugin for the bridge (no Pulseaudio, no Pipewire) at a sample rate of 48000. This causes a thread '<unnamed>' panicked at 'Can't set rate.', src/alsa_snd.rs:57:9 error when I run the example code.

A workaround is changing my jack configuration to use a sample rate of 44100.

The full stacktrace is below:

Same error for me too, I'm using pipewire:

$ cargo run --release --example simple
thread '<unnamed>' panicked at 'Can't set rate.', src/alsa_snd.rs:57:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Same for me too, I'm using pulseaudio on Manjaro.

I'm having the same issue. Is there any hope of a more permanent solution?
