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:  http://www.bargaincableusa.com/virtual-7-1-channel-sound-card-mic-in-stereo-out-p/a-229.htm  I just ordered one and will let you know what I find when I receive it.
