(RESOLVED) RDJv2.0.0.5 > USB Sound Card Problem

[KJ6EO]

Hello All - Thank you for reading my post.  I've been running RDJ for years and I've never had any sound problems.  Normally, I use a Professional PCI/PCIe Sound Card with a Digital Coaxial Output.  I then use a digital coaxial to AES XLR adapter to drive my audio chain.  Lately, I decided to try something different out of necessity.  I've got a SuperMicro Super Server (2U/4Node) that's about 12 years old.  I installed a backup RDJ Server on one of the nodes (RDJ v2.0.0.5 on Win7).  I had to put a low profile video card in the only PCIe slot that the server has.  So, the only way to have sound is to use a USB external sound card.  I'm using the Spdif optical out of the card into a TosLink Adapter (Optical to Coaxial).  When I feed this into my audio chain, everything is running at slow speed (like playing a 45 on 33 and a third).  Am I making a mistake trying to do it this way?  If so, what do I need to do it right.  Whatever it is, it has to be USB.  Your expert advice and suggestions are always appreciated.  Regards, Bill(KZNQ FM)

Hello All.  I resolved this USB Sound Card Problem.  I thought I'd share the solution just in case anyone else runs into this problem.  For whatever reason, trying to convert S/PDIF Optical to Digital Coaxial with an adapter didn't work.  I got sound, but the audio was running at slow speed, and breaking up.  So, the way I resolved this problem was to find a USB direct digital Sound Card that had a Digital Coaxial output.  What I found was the DOUK AUDIO U2 (U2 Pro Mini XMOS USB to Coaxial/Optical Converter (DSD Compatible).  The U2 Mini is a 192Khz pure digital USB Sound Card.  The U2 worked perfectly to drive my Audio Chain.  Normally, I use M-Audio 192Khz professional sound cards (PCI).  But, I have to tell you that the sound quality coming from the U2 blew me away.  It made a big positive difference in the quality of my on-air sound.  Although I'm using it with Win7 Pro 64bit, it's compatible with Mac OS 10.6 and above, and Linux with a UAC2 compliant kernel.  The U2 has been tested on Ubuntu and Daphile systems (x86).  The U2 also has a S/PDIF optical output if you need it.
