This is the strangest thing. All of a sudden while streaming from iTunes on my iMac the music is slower than it's supposed to be. I tried a couple of songs all the same thing. I connected my computer to a Bose Sound Mini through the same Bluetooth and sounds fine. I should mention that I have no syncing issues with my TV, that's all fine.
I have not found online anyone who has had this issue. I can't figure this out.
I suddenly started to have this problem as well. This is how I found your post. Everything else works fine, only the soundbar. I'm going to have to call Samsung. What OS version are you running. I'm on Catalina wondering if an upgrade to Big Sur would help or is it purely on the sound bar end, which I think it is. I should say everything works off my iMac bluetooth fine, the tv is fine. It's only the sound bar. My work around for the moment is to use my apple tv to stream sound via the tv which is not slow.
