Using pipewire causes APE to malfunction

Hello Nvidia team,

I have confirmed the APE sound card works find with pulsaudio.service. However, the pipewire doesn’t.

I do these steps to disable the pulseaudio and then enable the pipewire.

systemctl --user --now disable pulseaudio.service pulseaudio.socket
systemctl --user --now stop pulseaudio.service pulseaudio.socket

systemctl --user --now enable pipewire pipewire-pulse wireplumber
systemctl --user --now start pipewire pipewire-pulse wireplumber

Working:
Video of sound works

Not working:
Video of sound doesn’t work

You can see the sound bar always freeze when using pipewire. However, I can use arecord to capture my voice.

arecord -D hw:APE,0 -c 2 -r 48000 -f S16_LE -d 5 out.wav

I’m using the Jetpack 6.2 and the codec is rt5640 on our custom board. I also got some failure message from debug port.

Do you have any idea on this problem?

Addition information…when I use the pipewire, there is no application can record my voice., such as Audacity, gnome-sound-record or guvcview. Only the arecord command works.
