I'm wondering if not all Pixel 6's are affected. I'm using an Ibasso DC-05 usb-c external DAC/dongle with my Pixel 6 Pro. I'm listening to flac files through my Sony studio headphones and they sound pretty good. I'm using Poweramp as the music software player. I have the U. S. unlocked model bought from the Google store. So, maybe the bug is only affecting certain models and/or batches? Anyway, they should have it fixed for all by summer.
