Audio very low via bluetooth Android TV

Description

after update to 3.5 android TV audio is quiet. There is no option to select audio boost as from previous version. Previous I set volume to 35-45 via bluetooth, volume is high enough to hear. 3.5 same volume, is very feint, have to set it to 65-70 from max 100. TV audio out is ok, not as loud it should be between 6-14 from 100 max. tried different video, all same problem. No other issues with bluetooth audio from other sources (youtube, netflix other streaming) Tried Nova Media player and no issue with audio volume. bluetooth speaker Soundcore 3
