Galaxy S8+ speaker cuts out after 1-2 seconds...?

Started about a week or two ago. I have had my phone since launch day, T-Mobile is my carrier. Randomly have sound cut from external speaker, and it fades out, not just cut out.... there is a lively conversation over at Samy's site. here is the link - https://us.community.samsung.com/t5...d-id/GeneralDiscussion/thread-id/2913/page/35

Anyone experiencing this?

I have the S8 and it's been happening more often of late. Absolutely irritating. And isn't relegated to one app, like YouTube, or consistently occurring the same way either.

Really hoping for a fix soon.
 
I experienced it last night. Changed cases everything went back to normal.

I checked that samsung forum link up thread and someone posted that Samsung acknowledges its a problem and they are issuing a software patch for it later this week. Take it for all that's worth.
 
I have noticed if you turn the screen of via the power button, and unlock the sound comes back, albeit not always permanently...
