Pixel 2支持USB Audio Class 1/2/3，哪些USB音频设备兼容或不兼容？

Hey there, let's break down exactly which USB audio devices work (and don't work) with your Pixel 2, based on official details:

• All USB-C audio devices that comply with USB Audio Class 1.0/2.0/3.0 standards and transmit digital audio signals via USB-C. Examples include:
  • USB-C digital Bluetooth audio adapters (those that handle digital signal transmission, not just simple analog conversion)
  • USB-C digital headphones with built-in DAC chips
  • Professional USB-C external audio interfaces/sound cards that follow the USB audio class specifications

• Any device that only transmits analog audio signals via USB-C (no built-in DAC chip for digital-to-analog conversion). These will trigger an "unsupported" warning notification on your Pixel 2 and won't work properly. Examples include:
  • Cheap, basic USB-C to 3.5mm analog audio adapters (without integrated DAC)
  • Older external speakers/headphones that use USB-C for analog signal transmission (no digital processing module)

A key official note: The Pixel 2 only supports USB-C audio devices that use digital communication, not analog signal transfer, and adhere to the USB Audio Class 1/2/3 specifications.
