Audio over USB-C

The USB port on the device exclusively uses “Audio Accessory Mode” for audio, which only allows audio as an analog signal⁷. This boils down to the device not supporting audio cables that have a DAC (Digital-to-Analog Converter) anywhere within them. Many USB-C to 3.5mm adapters have a DAC built into them, and will not function. Adapters of without DACs may be found online, but may not advertise this.

Inline remotes have yet to be tested.
