H A Dusb.rst2 ASoC USB support
7 In order to leverage the existing USB sound device support in ALSA, the
8 ASoC USB APIs are introduced to allow the subsystems to exchange
11 One potential use case would be to support USB audio offloading, which is
12 an implementation that allows for an alternate power-optimized path in the audio
13 subsystem to handle the transfer of audio data over the USB bus. This would
