Audio stopped working on AJA io4K
on Apr 15, 2020 at 11:13:15 am

Hi folks
I've got a MacPro (2013) running OS 10.14.6 with MediaComposer and Premiere Pro.
Thunderbolt 2 to AJA io4K.
I've got picture out on SDI but the sound has suddenly stopped. Nothing from either the phono outs or the headphones socket. Same with both NLEs.
I've tried both Thunderbolt ports and swapping out the Thunderbolt lead.
Sound perfectly OK via a Blackmagic UltraStudio4K (which I generally use with Resolve), but the fan on it is quite loud so I prefer the AJA for general editing, plus the sound quality is better.
I've checked the preference settings in the NLEs which are fine.
Any thoughts anyone?

Kind regards
