AC3 audio dropouts on live TV playback

[sgilani]

I'm seeing a new issue after installing 5.0.8. I'm capturing HDMI with AC3 audio with an HDPVR2. When watching live TV on the Windows client, I get audio dropouts every few seconds. However, if I make a recording, that recording plays back fine. Live TV also works fine via Kodi, the web app, and VLC--so this seems to be an issue solely with the Windows client and only while watching live. I tried different decoders and fiddled with the audio renderer settings to no avail.

Hitting pause for a second or two (so that there's a small buffer ahead of playback) seems to help clear it up.

Logs attached.

Few updates: so this affected more than just AC3, it also affected channels with AAC, and the video decoders kept trying to deinterlace progressive material, resulting in horrible bob artifacts and lower framerate. Updating drivers didn't help.

Turns out, recently my Windows 10 had been updated to build 2004 even though I've disabled automatic updates. I rolled back to the previous build (1903) and now everything is fine. I've now hopefully prevented any updates from happening again and I'll stay on this build.
