For the users of the Google Pixel 6 series, there is some good news. The upcoming June Feature Drop for Pixel devices will bring a handful of changes that will be good for the device. Pixel 6 now has support for "Direct USB Access." a feature that will actually allow for better DAC support.

For those wondering "Direct USB Access" in Android 12 acts as a path that allows apps on smartphones to directly access an external DAC. This, in return, would open gates for more USB DACs being supported as well as better support within the apps.
