PulseAudio Over Bluetooth Delay

I've been noticing a significant audio delay over my Bluetooth headphones using PulseAudio. Does anyone know of any steps or modules I can enable to resolve this?

I experience the same with my Bluetooth headphones. I haven't had the time to look into it yet, but you could try changing the latency in the Pulseaudio Volume Control ('Output Devices' tab; click on 'Advanced' and change the 'Latency offset'). Other things to try are given on the following Ask Ubuntu page: Get rid of 0.5s latency when playing audio over Bluetooth with A2DP.

I have Avantree Leaf USB dongle. It does not use Linux bluetooth, for Linux it is USB audio device. And the audio is delayed about 200 ms.

perdomwx,
I have just tried what I suggested earlier, viz. changing the Latency offset in PulseAudio Volume Control. Works a treat with my Bluetooth cans. In my case (AKG Y50BT) I adjusted the offset to +200.00 ms. I just played around with the offset until I arrived at one that was in sync with the video.
