Rpi 3 Libreelec Pulse audio stuttering playback & no audio

Hi

I hope you guys can help me.

I installed librelec 8 fresh in rpi 3.

When i switch audio to pulse audio. I have audio for like 20 seconds then the audio dies off ( Bluetooth still connected) and the Video playback goes down to 1 fps.

The System load is fine a couple of percent CPU usage and memory is shown with 21% usage.

Even after i switch back to HDMI audio it still Stutters.

After i did a Hard reset it was fine again but as soon as i activated pulse audio out again this behavior came back.

Player is mmal Hardware ( default).

Even if i use omx player it doesnt stutter but no Bluetooth audio.

Is there anything i can do?

Problem is solved. Apparently it is a Hardware limit oft rpi3 Bluetooth and its not capable of streaming high quality audio. I am using a Bluetooth USB Adapter and it works now.
