Some backbox sounds crackling in 10.8 GL x64 at any volume

[griffindodd]

Hi all,

 

I'm LOVING 10.8 GL with frame pacing, it's just so smooth and low latency. However on some tables I've noticed that the main sounds can have a harsh 'crackle' at what seems to be certain frequencies. In the past lowering the ROM volume helped but this seems to be different. Doesn't happen on all tables, just a few here and there, and only on certain sounds.

 

Anyone else come across this?

 

Software: VPX 10.8GL x64, VPinMAME 3.6, B2S 2.1.3, FlexDMD 1.9.1, Freezy 2.3.1, Pinup Popper 1.5
Screens: PF: Sony X85K 4k 100hz Portrait, BG/FullDMD: 1080p Portrait, Topper: UHD LCD
Computer: Ryzen 9 5900X, 64GB, RTX 4080 Super, NVME, Win 11

@griffindodd do you have a sample of what it sounds like? Does this also occur if you lower the resolution to 1080p?

Thanks for the reply.

 

I don't have a sample, it comes across as more of a shrill crackle/crack (for lack of a better description). Lowering resolutions isn't an option on my main display, however, just to clarify, I don't use digital outputs such as HDMI or Optical for the sound that is being effected, it is using a good-old speaker jack from my onboard audio to a pair of desktop computer speakers, nothing fancy.
