You have to find if there is any setting to pull it back to stereo.
When using chromecast on youtube the audio comes thru my bluetooth speaker until i cast the video to the Sony TV. The tv has it's own sound so that is not an issue. Is there a setting i need to adjust so the bluetooth speaker will work when youtube videos are displayed. The question is for a friend who uses a soundbar with his Sony big screen and when he goes to youtube with chromecast the sound does not come thru. I was hoping the bluetooth speaker would solve his problem. This problem does not affect me in the same way as my Sony big screen does not go thru a soundbar. Got a wonderful JBL Flip 4 speaker and am blown away with the sound quality. Watching youtube vids on my Netbook which has poor speakers and sound volume is so much more enjoyable with the Flip 4 as the sound source.
