i use my phone for listening to music, some times for internet and some old apps therefore android 7 and 6 are not much different for me.
but difference between Exp output and the other one is explicit,as i said i don't had problem with build 703 and android 6.
therefore i will downgrade to marshmallow and i should backup and then download android 6 rom and flash it ,. . . that may take half of a day from my time so i don't want to bother you and developers or fuss, I have a question will this problem be solved for HTC A9 in next beta for android 7? UI ,final release and other things does not matter to me i want have Exp output and listen to lucid music from my earphones.
sorry for bad english.
