All audio on streaming video out of sync

[Gaijin]

All of the audio for videos played on my AppVMs, regardless of what
template it's based on (Fedora 24/Debian 8), or what browser I try
(Firefox/Chrome/Vivaldi), is completely out of sync. It's not just
YouTube, but Vimeo, self-hosted, etc.

I tried uncommenting audio_low_latency in /etc/qubes/quid.conf in dom0
That didn't fix things.
I tried playing with the realtime-priority in /etc/pulse/daemon.conf
That didn't seem to make any difference.

Are there any other places where I could try to fix this latency issue?
I assume it's dom0 as everything is affected.

whats your pc specs/ what soundcard?

[Gaijin]

I'm running Qubes R3.2
Sound is going through an nVidia GeForce GTX 560 Ti card. I don't have
nVidia drivers installed.
This machine has an Intel Core i7 2600 @ 3.40GHz CPU and 16.0GB
Dual-Channel DDR3 @ 665MHz RAM.

How are you plugging it in? HDMI? if so you got further then I did. I dont' get sound from hdmi only video. Why not just use the onboard sound card?

[Gaijin]

Oops I was going off an old hardware report from when this machine ran
Windows. Got under the desk to check, and sound is going through the
motherboard: ASRock H67DE

It operates fine usually, and never showed this sort of issue from Qubes
1.x-3.1. When I upgraded to Qubes 3.2 I started noticing this lag. I
don't watch a lot of video so it took me a while to notice.

lag only with video? dunno, maybe you can downgrade the dom0 kernel?

to throw some other ideas out there, check bios settings, maybe disable the other card. have u turned off hardware accel in the browsers? html, flash.
