Still have cracking with AirEthernet, more subtle, but still there, and very irritating experience. I put back my trusty USB again. Haaaa! what a relief. More I test this Air, more I'm very sensitive to those cracking noise, and now I can't just tolerate a single one, even one per hour .
@windler, I use Jriver (or itnues), with Devialet USB Audio 2.0, and don't have any problem at all that you have.I can suggest to do a fresh re-installation to resolve your issue (backup you personnal datas/setting before), you can make a fresh installation with a USB key with DiskMaker (note that I'm not affiliate to them at all, just put the link to simplify searching) http://diskmakerx.com/
