Any chance you could try with an updated kernel? It's not clear to me if this is a real issue or just a warning that's been fixed since by commit.

bbf7d3b1c4f40 "ASoC: soc-pcm: Fix DPCM lockdep warning due to nested stream locks"

You may also want to open a bugzilla issue to attach the full dmesg log and your configuration reported by 'alsa-info'

After I removed pipewire software the error message was disappear. But the sound and media still doesn't working and alsamixer cannot change sound card to my usb audio device.
