Kodi 21 – Fire Stick – No Sound After Sleep or Screen Saver

Hi. I have a Fire Stick 4k Max. If I pause a video and the device goes to sleep or the screensaver comes on, Kodi 21 will lose all sound when I return. The only way to get sound back is to close Kodi and reopen it.  This never happened with Kodi 20.  Anyone else having this issue?  I saw someone else mention this issue in the hardware thread @ https://forum.kodi.tv/showthread.php?tid=364384&page=13.
