are there any specific configurations or recommendations for dealing with audio playback on Android 11 giada jhs 558 and ensuring low-latency performance mode is enabled?

Question

Hello, I'm facing a problem. I'm using implementation 'com.pierfrancescosoffritti.androidyoutubeplayer:core:12.1.0' and implemented in my android app project. It works so well if i ran on virtual device android 11 and physical mobile Realme 5pro while on giada DN74 android 11 device it is like continuous cutting while playing the video and i find this error in my console 15:12:18.255 10720-10822 AudioStreamBuilder com.xlab.andsign D build() MMAP not used because AAUDIO_PERFORMANCE_MODE_LOW_LATENCY not requested.I don't know why this happens.

If the video is cutting, AAUDIO_PERFORMANCE_MODE_LOW_LATENCY might be a red herring.

[mariam-wahba]

Hello @PierfrancescoSoffritti
i don't understand what do u mean.
I lately edit my code to this to the following code , the video is somehow playing smoothly but it pauses in some times for a second but still experiencing the cutting in audio... as if there is audio distortion and still i get the same message in console "AudioStreamBuilder com.xlab.andsign D build() MMAP not used because AAUDIO_PERFORMANCE_MODE_LOW_LATENCY not requested"

I see, the issue you're experiencing is probably related to webview. Maybe you can find a configuration for it that solves your problem?
