This will change with Asio4all installed. The greyed-out box just indicate that Sibelius is looking for an ASIO option but doesn't find it. What this means is that it (Asio4All) can help with the problem, a little, hopefully enough to make playing the keyboard less annoying. I recommend to test different settings here, playback and adjust again to find the optimal settings for your setup. However, minor tweaking is possible with it such as buffer sizes and adjustment of internal latency to get most out of your ordinary drivers which is use in the end. This is because Asio4all is more a interface 'wrapper' than an optimized driver - it fools the system into thinking there is an actual asio driver for your card there (but it works). This will give you the ASIO interface but not necessarily the low latency that comes from using a dedicated ASIO driver. I'm afraid you are stuck as the Realtek chipset doesn't have a dedicated ASIO driver.Īs tomeoftom's mention in his answer, you can use the Asio4All.
