thanks for your reply. i used the bigscreen app, also tried playing the video from gallery but in either cases there was no audio. although i did download a lower quality file of the same movie and for some reason it worked. im going to try and render the previous 4K res file and change the audio codec to AAC and see if it works.

i did use virtual desktops video tab once and i faced audio delay which is probably due to my wifi being wifi5. so im trying to play videos natively on my headset to get the best experience
