Yes, you can use soundcore VR P10 in PCVR by using a Link Cable, but there are two simple steps you need to follow, which is also shown in the quick-start guide:

1. Do not plug the Link Cable to the USB-C port directly, it does not support data transfer. Please plug the dongle into the USB-C or USB-A port (by using a USB-A to USB-C adapter) on your PC instead of your VR headset.

2. Connect the Link Cable from another USB-C port on your PC to your VR headset and choose the audio output as VR P10.
