I think you need to check your code because there are no issues with playing audio. Perhaps you're attempting to play audio before a successful connection to an EZB that supports an audio codec.

hi dj

as you can see the ezb is connected in the picture above . it seems that ARC or Auto Position dont recognize my ezb . i use this one for many years . the previous version no problems . it started the last update .

Make sure your soundboard is on ezb index #0

it is on index #0 .when i choose in Auto Position my ezbv4/1 it doesn save .

Hmmmm - i'll have to take a look and see if I can reproduce it.

also the rgb seems to work in the window but not the rgb itself . the standard rgb lids up thats all .

i deleted all ARC and redowloaded .now its changed .it says connected.  still same errors .

could it be possible that there is no save button on the page where you choose your device ? ( unknow )

There is a fix in the latest release here: https://synthiam.com/Products/ARC/Releases/ARC-2021-10-03-00-Early-Access-Runtime-20785
