Chipping/Crackling noise on HDMI

[FWM]

Im running a HDMI cable from my GPU to my home theater system, and have set the VM to use that Audio output.

Unfortunately im getting a chipping/crackling noise. I never used to get this noise using the same setup but running windows, so i dont think its the hardware or cable.

Any suggestions?

You forgot to include required info such as hardware specs and the
versions of qubes/guests and your media software that you are running.

Sorry
Running Qubes 3.2
Debian-8 template
GPU is a HD6950

Software is VLC

What drivers are you using for the video device?

Is this a qubes-specific issue? (have your tried other linux distros)

Have you tried enabling low-latency audio mode for the affected VMs?

There is also a pulseaudio line you can edit in a config file. I've had cracklings in the past, I'll try to google it for you.

had a similar problem, also with radeon hdmi. in sound settings theres a checkbox labeled DTS. no clue what it is, but that fixed it. still had some sound sync issues when playing videos on youtube.
