HDMI audio sounds like chipmunks in PipeWire
The audio output from my HDMI TV sounds like chipmunks (high pitched stuttering, sometimes gaps). I'm using PipeWire/Wireplumber and Sway.
Setting frame rate from 60Hz to 24Hz didn't work, changing HDMI port on my TV didn't work, setting
default.clock.allowed-rates = [ 441000 ]from default `48000` in `.config/pipewire/pipewire.conf` didn't work.
I'm out of ideas.

Re: HDMI audio sounds like chipmunks in PipeWire
Is the sound ok on the internal speakers or headphones?
Do you have another HDMI device you could test (ie. whether this is specific to the particular Tv)?

Shouldn't this be
default.clock.allowed-rates = [ 44100 ]?
441000 is indeed a very high sampling rate.

But was apparently a mitigational effort anyway?
setting

Yes, both are ok (if I set output to `analog-stereo`).

Currently, no.

Sry, I indeed have set `44100`, not `441000` (typo, my bad).
