Samsung Q85 One connect sound issue

[SunnyMan]

Hi, I have an intermittent issue with sound loss when switching to other hdmi sources connected to the one connect box. 

HDMI 1 - Sky Q box
HDMI 2 - Amazon Fire TV Box 
HDMI 3 - Samsung Sound-bar
HDMI 4 - PS5

When I switch over to the fire tv box or PS5 I sometimes get no sound and the only way to get sound back is to disconnect the one connect cable for a second. I have tried different HDMI cables but still have the same issue. As mentioned it doesn’t happened every time, it’s intermittent. Has anyone else with the one connect box had this issue?

I'm still on firmware 1401 on my Q85R .. does this 1409 firmware thats available to install via USB solve this sound issue in any way?
