Yes, and it works perfectly well. The issue appears to be that the codebase is 64-bit and the interface piece is 32; this made for some trouble that hasn't been resolved in trying to get a driver to "play nice" with the hardware. But a USB sound adapter works fine; I've been running one now for a nice long time.=C2=A0 It has another advantage as well; the built-in sound, wh= ile it works on the Pi2 and similar, has (IMHO) a crap noise margin and thus even a $5 USB adapter sounds better! --=20 Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/
