MTK HIFI output disappeard in the newest version


Recommended Posts

I also experienced the same thing, I used the realm 6 MTK android 10, before updating v3 build 870 can use the HiFi output mode but after updating to build 870 can only use the Open ES ES-SL output mode.

There are 0 changes in this regard, but I guess you updated to Android 10? It works OK on my device, but it's on Android 9 and no Android 10 OTA on sight.

@maxmp Maybe my text layout is confusing, I am embarrassed, but I did post the logs of versions 860 and 871. The logs of version 871 are just behind the logs of version 860.

But this is not a problem, I just send it again

 

here are the log of 871 version
