Success using a Type-C Sound Card (HiFi Magic Voice 7.1CH). Cost was only $7 and works perfectly with the Beelink U59. No latency issues either and good volume.

Great! Congrats on getting this to work. The adaptor you bought doesn't seem to be available her in the states but there are many other inexpensive adaptors available here that seem to be just like the one you have. I'm going to get one or two to try out.

Because my Beelink U59 mini computer is mounted on my robot and connected through USB this gives me a good alternative other then running my robot's voice through the EZB. I'll have to migrate all my EZB soundboards over to PC soundboards in ARC though.
