Last week I received bug report from iBasso DX90 user that player sometimes stop playing next song. It didn’t happen during the tests because it often happened after 10 songs played, sometimes after second loop of the album.

I spent the whole week investigating why this happened and I found that removing Equalizer and Gapless on Advanced Purist ROM will trigger this bug. To resolve the case, I brought back those features in Advanced Purist but kept audio effect engine removed.

iBasso DX50/80/90 will contain the following features as below:

-Based on most recent version from official iBasso website
-System font was replaced with lighter version of Nimbus font
-build.prop tweaks for better video and storage performance and improve battery life
-audio engine optimized for only audio playback (EQ/Gaplass features work)
-bundled audio effects removed but keep main engine
