Hello. It took me a while to understand why my microphone was crackling when I was using Big Box but I finally found the culprit (thanks to the AI), the crackling is disappearing when I totally disable controller detection in Big Box. It seems like Big Box’s HID Polling/Controller Scanning is saturating my USB bus or creating DPC latency spikes that conflict with my USB microphone even when the software is in the background, any solution if I want to keep gamepads enabled ?
What I have already tested (without success):
Changed Process Priorities (Big Box to "Below Normal", OBS to "Above Normal").
Locked Big Box at 60 FPS and disabled all overlays (Nvidia/Discord).
Matched sample rates (all devices set to 48kHz/16-bit)
Changed USB ports (tried USB 2.0 and 3.0).
Set Windows Power Plan to "High Performance" (Minimum CPU state at 100%) and GPU at high performance.
Tried both Windows Media Player and FFmpeg video engines in Big Box.
My setup:
Windows 10 (22H2)
LaunchBox/Big Box (13.26-beta-2)
Samson Meteor USB Microphone
Controller: [8bitdo adapter + SNES classic controller]
Inte core i5-4460
RTX 4060
16GB DDR3
ASROCK B85 pro 4
