No sound on Huawei P20

FMOD Engine
1

I’m using FMOD 2.00.05 library on Huawei P20 and no sound can be played.
I’ve tried sounds with samplerate 48000 / 41400 / 32000 and same thing, no sound.

the error is
2019-11-15 00:35:32.510 3196-3223/? W/AudioTrack: AUDIO_OUTPUT_FLAG_FAST denied by client; transfer 3, track 48000 Hz, output 48000 Hz

From what I’ve read the eror “AUDIO_OUTPUT_FLAG_FAST denied by client” appear when the phone doesn’t support “android fast audio path” . But FMOD is implemented using this type of support.

I cannot see any FMOD logging in there, do you have a log file with any/more FMOD information?

The issue was resolved after changing the initialization way

FROM

thank you for your support
