The interface for audio playback is not always recognized

[0a00]

This is my WPCTL Status.。。。。，
I have tried various interfaces but cannot correctly recognize the interface for playing audio unless I manually select loopback as the audio playback interface. However, if I choose this computer and there is no sound, what should I do? This is my device information。。。thanks thanks

pipewire should work out of the box if you just leave cava unconfigured. (it should be default in latest cava)

your 101. Family 17h/19h HD Audio Controller Speaker + Headphones [vol: 0.40] looks like your default sink and cava should by default also visualize whatever is coming out from there.

if you have some older version of cava it might be trying to use alsa directly. what is the output of cava -v?

❯ cava -v
cava 0.9.0

The arch repository used should be the latest version, and I am not sure if it is a problem with my audio service configuration or something else. I also attempted to modify the configuration file.

As shown in the figure, when I selected the playback to Loopback Analog Stereo, CAVA worked normally, but as a result, the computer lost its sound,

hi @0a00

0.9.0 is not the latest version

there is a bug in 0.9.0 where this would happen. It is described here #518. This is fixed in 0.9.1. Please make the arch package maintainer upgrade to 0.9.1

The update to the new version is working properly. Thank you
