sizzling/crackling sound on aarch64 #30

Hi,

Thanks for maintaining this great project!

I'm experiencing bad sound quality issue in this configuration:

- Server side- OS: ubuntu 24.04 Machine: nano pi t6 - rk3588 SOC Arch: arm64 Sound system: Alsa and pulse Roc-recv: v0.4.0 fec: disabled

- Client side- OS: ubuntu 24.04 Roc-send: v0.4.0 Integration with pipewire Machine: intel x86

I tried to swap the machines and it passes: roc-send on arm64 and roc-recv on x86. So i guess it comes for the receiver. It also happens with sender and receiver on the same host. The sound is not choppy. It s feels like it has high frequency continuous radio-like noise added to the normal sound. This is very stable, and and latency / frame size settings don't make any difference.

Thanks for detailed report. Others reported a very similar problem too, however I was never able to reproduce it. I'll try to setup environment similar to yours when I'll do testing roc-toolkit release next time (0.5).
