I have an internal soundcard, MAudio 2496, I switched to the CI2 and it has worked fine for over a year, until now. Works better for me than the 2496 (or did).
My image shows LatencyMon, it says 'Your system appears to be suitable etc." and latency in Cubase; input latency 5.578 ms, output 8.299. It has always been about that and should be fine, but I ‘hear’ at least half second of latency. ASIO-guard says 11 ms, but it makes no difference on or off.
