meher21 , via OnePlus 7T , Oct 10, 2019 : I just bought the 7T and to my surprise, my Wireless buds which support aptX codecs and HD audio are not getting the same audio output from my 7T that I got on my 6. The Bluetooth settings don't have a 'HD Audio' option. I'm unable to manually select the aptX or aptX HD codecs from the Developer Options as they revert back to system default as soon as I exit developer options. Anyone else facing the same?? Has Dolby Atmos got something to do with this?? P.S: The wireless buds are working absolutely fine and with HD audio on my Pixel 3XL along with my old OnePlus 6.
