In April of 2015 I purchased 5 USB sound dongles from an eBay seller with
the name bargain cable usa. All 5 that I ordered had the CM108 chip and
they worked fine on Allstar. eBay listed there website as
www.bargaincableuse.com Sometime
in the last year they stopped selling on eBay. Today I when to there
website and they do have what appears to be the same (looks the same from the
outside anyway) USB sound dongle listed on there website here:

I just ordered one and will let you know what I find when I receive it.
