Pauses in Audio and Video
JimH:
Why don't you use WASAPI?
Is this only madVR? Did you try JRVR?
htnut:
Yes the exact same dropouts occur when using JRVR.
I use DirectSound because I have a pre-movie sequence that I run before the main feature starts. WASAPI requires "exclusive mode" which locks the audio stream while the queued-up movie is waiting. Before Hendrik "fixed" DirectSound bitstreaming, I tried many different solutions but find that WASAPI won't work in my application, requiring DirectSound.
JimH:
WASAPI shouldn't require Exclusive Mode.

"power users":
I've been using the NVCleanstall utility to trim back about 135Mb of cruft, advertising, and telemetry from the standard Nvidia driver. The only things I leave in are the video driver itself, the HD Audio driver, and the Optimus driver because I have notebooks as well as the desktop systems to support. I don't game so going a minimalist route for this driver package works for me.
Depending on the revision level of the driver you're modding, there are advanced/experimental options that let you shut off/disable most of the default NVidia power saving/throttling options INCLUDING the Nvidia HD Audio device sleep timer. See attached screenshot.
Have a look at your Windows power plans, there are deep settings for USB selective suspend (power off) and PCI power management, both of which I disable.
And...... if you have Samsung NVMe storage devices, try downgrading the driver from the Samsung (current revision 3.3) NVMe driver to the factory stock Microsoft NVMe driver that is included with Windows. There are long-standing threads on reddit and other boards indicating that while the Samsung driver gives some slight increase in write speeds, there can be stability problems along with reduced read speeds.

Try it yourself, and Hendrik confirmed: Media Center will NOT bitstream (throws an error) if WASAPI selected wihtout "exclusive" mode checked. In Hendrik's own words on Doom9: WASAPI in shared mode is rather cursed. Its not that helpful. For WASAPI you should always want to use Exclusive.
