After 4 years being wireless, I'm going wired again. I dusted off my old AKG K550 headphones and bought a new #DAC. The #HiBy FC4 sounds great with MQA from #Tidal. It also works fine with Linux.

An interesting finding is that #PipeWire resamples everything to 48 kHz by default. If you want higher sample rates, you have to tweak the config.

@sesivany So when I take my 44.1 kHz audio source, remix it in my DAW and then export it as 44.1 kHz audio CD, it gets resampled at least twice (44.1 > 48 > 44.1) when I run it through PipeWire?

@fuxoft @sesivany The DAW should tell you what rate it's working at (Ardour does at least). You can use PW setting 'clock.allowed-rates' to allow other rates than 48K at system level, and PIPEWIRE_QUANTUM env variable to tell individual apps at what rate & buffer size they should run. That at least works when going upwards to 96K. I now tried 44.1K and Ardour still reported 48K, i'm not sure why. I had to set PW setting 'clock.force-rate' and now Ardour reports running at 44.1K.

@jistr @fuxoft@kompost.cz I think there is an API the app can use to negotiate with PW what sample rate to use if you allow more rates. But if the app don't use it, the default one is used.

Interestingly @trilobyte found out that if he runs Audacity on PA backend, it negotiates the sample rate, if he runs it directly on PW, the default one is used. Seems like Audacity supports it for the PA API and hasn't implemented it for the PW API.
