It really sounds like the card doesn't like the sample bitrate or something. I've heard noise like that when there's a mismatch, i.e. if one side uses F32 and the other S16_LE ...
But that still wouldn't explain why clients don't see the correct samplerate ...
]]>Did you find a combination of sample rate, frames, periods that work for your system?
Some sound cards only work with frames as a power of 2.
I just got a new laptop, a Lenovo flex 5i. Sound in general (with pulseaudio) is working fine, I installed the sof-firmware, etc.
The only problem I found is with JACK (jack2). Sound is horribly distorted with Jack, no matter whether I run Firefox, SuperCollider or my own software.
I tried with an external USB sound card and it works fine.
EDIT: Another symptom is that the samplerate is not detected correctly. I.e, when starting JACK with a samplerate of 44100, SuperCollider still detects 48000.
ANOTHER EDIT: PipeWire works as well ..
Is this a known problem ? Is there a fix ?
Here's some info:
