![]() ![]() The WDM driver's output appears in Media Center's playing now as a library item named IPC. If your combined buffer settings are below this threshold, and you still have noticeable lipsync issues, there may be other factors contributing to your latency other than the WDM Driver, such as that native latency of your audio device or using certain DSP modules (such as Convolution). Most delays below 45ms will not create visible lipsync issues, and higher latency may or may not be noticeable to all viewers. The recommendation for lipsync in film is about 22ms the recommendations for television are about 45ms. The total added latency is close to the sum of those two buffers, so you want to try and find the combination of buffer settings that creates the lowest total latency, but doesn't cause audio drop outs as described above. If you're experiencing these issues, you can adjust the two buffers listed under Clicks, Pops, and Static above. ![]() ![]() For pure audio applications, this is irrelevant, but for streaming video (or video games), too much latency can cause lipsync issues. Different hardware configurations work best with different combinations of settings, so try different combinations large and small until you find settings that resolve your issue.īecause the WDM driver requires some buffer to function, it necessarily adds some latency to audio. It is important to note that a larger buffer will not necessarily work better. If you are experiencing clicks and pops, try different combinations of settings with these two buffers.
