I have my phone connected via USB-C to USB-B into my dac/amp. When I try to play any sound, all I get is a crackling sound, which doesn't stop once I try to play sound. I saw another question about this, but the answer in that thread doesn't apply, as I can't find any hardware acceleration option in dev. options.
I've also tried using a Pixel 2 with the dac/amp, and get the same result.
