We used this sound card to connect to the phone, and only saw the following information in the log, without specific sound card model information:

usb 1-1: New USB device found, idVendor=0d8c, idProduct=0014, bcdDevice= 1.00
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: USB Audio Device
usb 1-1: Manufacturer: C-Media Electronics Inc.
usb 1-1: usb_probe_device

We currently do not have an effective way to obtain the detailed model of this sound card. We are very sorry.

Thanks
