Automatic switching between 44.1 and 48khz works fine, but anything higher not. For 88.2/96 khz and 176.4/192 khz the USB mode must be switched, but nothing happens. When setting the sample rate on the audio interface itself, audio output stays silent. **System**: - Fedora 43 - Pipewire - Latest firmware on the interface What do you need from me? Could this be an issue with pipewire rather than alsa or ucm? If yes, do you maybe have any resources that could give me some hints? Consulting existing issues, forums, chatgpt and perplexity did not result in any improvement. Thank you very much for anything that could help.
