Pauses in Audio and Video

htnut:
The BIOS tweaks did improve the DPC latency.

But sadly, the dropouts occur just the same.

All of the Ch 4 Glitch Free suggestions were already set properly from my original install.

Attached is the LatencyMon output after the movie ended.

Things I haven’t tried are a virgin W10 install with noting but MC31; and using a different Amp.

Theres still a few things we can try;

Make sure you are running in 'Ultimate Performance Mode':

'Unhide' the following and set them in the Power Plan.
Core Parking - off
Processor idle promote/demote treshold - 100%
Processor performance core parking min cores - 100%

Turn off Core Isolation:

Disable the Dynamic Tick using this CMD:
bcdedit /set disabledynamictick yes

Let us know how it goes... and post that LatencyMon benchmark!  ;)

Hi all,

Sorry I've only found this thread now.

I've reported since that the long video+audio freeze was back, so the Windows update "improvement" was just a coincidence.

I've also tried both older (532.03) and latest drivers, the issue is the same.

I've also recently started using a DP 1.4 to HDMI 2.1 adapter to resolve the black screen issue in 4K24 10/12 bits with recent drivers when using an HDMI 2.0 input on an AVR with a HDMI 2.1 GPU (3090 in my case) and the long freeze/drop is still there.

I always disable widgets, so not the cause.

I'll try to go through a few of the tips in this thread and I'll report back if anything helps.

I should stress that as far as I'm concerned (and unlike @HTNUT) I have similar issues with MPC-BE, so it's likely a system/driver issue rather than a JRiver issue per se.

Most excellent, I had no idea there were so many "hidden" power options.  I implemented all of your tips except "Core Isolation", my system says this feature isn't implemented.

Sadly, I still encounter the same dropouts.  Attached is the new LatencyMon screenshot shortly after the dropout.

SimplySound:
Well, your latency is looking better, but that doesn't appear to be the issue. 

I think Manni may have it right that it could be a driver issue.  What are you using for your Video processing?  Is it integrated or a dedicated GPU?  If you are using NVidia, have you tried working with the video driver? 

I have used NVSlimmer to slim down my video driver, but again, I use Kodi and I use WASAPI as my HDMI interface protocol.  So what you are experiencing is not something I've seen.
