Same issue here. AMD gpu, two 4k monitors, one on Display Port @ 60Hz
and The other on HDMI @ 60Hz with audio playback high pitched and
increased speed. Lowering the HDMI refresh rate to 30Hz fixes the audio.

Very similar issue over here. I can logon to X11 and run 4k at 60 Hz
without issue. However, when I logon to Wayland and run 4k at 60 Hz all
audio and video plays back at 2x-3x speed (YouTube, VLC, mp3, etc). I
have an AMD GPU and am running off the DisplayPort through a DisplayPort
to HDMI

Yes the kernel graphics driver provides the path to the monitor audio
device so that might be it. Although history makes me suspect PulseAudio
more.

I just tested it on a laptop with intel graphics, and sound and playback is
perfectly normal on 60Hz when playing through the HDMI (playing on the
television). Same cable, same television - only connected to my laptop instead.
This makes me wonder whether this could be an issue in the kernel
I don't know if the speed is exactly doubled, by but changing the output
definitely changes the playback speed of any media.
I tried making a video to show it: https://youtu.be/hlqw_ijdxOE

I don't think it's quite doubling. Usually "chipmunks sound" bugs are a
mismatch between 44.1kHz and 48.0kHz somewhere in the system.
The refresh rate of the monitor should be completely irrelevant to any
audio.

However, audio going through USB on the X1 ThinkVision (called "Analog Output -
X1") is now playing correctly in Wayland with both monitors at 60Hz.
When selecting the television output "HDMI / DisplayPort - Vega 20 HDMI Audio
[Radeon VII]" on Wayland with 60Hz on both monitors, the playback
This does not fix the issue. Playback is still double and high pitched in
Wayland with both monitors at 60Hz.
In Xorg I can still only select 30Hz as the maximum on the television.

Please try editing /etc/pulse/daemon.conf and change:
; default-sample-rate=44100
to
default-sample-rate=48000
and then reboot.

Also because Wayland allows the television to be at 60Hz, whenever I
login (after boot) and have it in mirror mode, the sound is therefore
too fast by default.
I cannot change it, since the HDMI port is the first port on the GPU and
the DisplayPort port is the second. This means it by default
