I have an issue with persistent static while playing audio from the DisplayPorts and HDMI port on my RX Vega 64. I do not have static issues while playing audio with headphones plugged into the motherboard audio port or front panel headphone port. The static plays on all sounds (system, video playback, music, application sounds, and etc...)
I've tried the following and haven't had any luck resolving the issue.
1 - Disabled "Give exclusive mode applications priority" in Sound->Properties->Advanced menu
2 - Tried all the different audio formats in Sound->Properties->Advanced
3 - Disabled all enhancements in Sound->Properties->Enhancements
4 - Uninstalled and reinstalled the AMD Crimson Relive software package (my assumption is that this includes all installed drivers including audio. let me know if I'm wrong)
5 - tried multiple display port and HDMI cables
6 - tried 2 different monitors. One of which was the monitor that was bundled with the graphics card
Radeon software version: 17.11.1
AMD High Definition Audio Device: 10.0.1.4
Windows 10 Pro 64bit: Version 10.0.16299 Build 16299
Any suggestions or tips on what to try next would be greatly appreciated. From what I can tell the card performs as expected outside of the audio issue. I can't detect any visual issues with the output coming from any port.
