i've had the same problemish i think?i'm trying to run any music programs to them becoming distorted. i've done everything possible. i've tried other pc aswell they work on them(intel). so maybe the problem is with the cpu?? here what my latecymon said. maybe it'll help get our problems fixed. Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. LatencyMon has been analyzing your system for 0:18:12 (h:mms) on processors 0,1,2,3,4 and 5. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: NONYA OS version: Windows 11, 10.0, version 2009, build: 22000 (x64) Hardware: B450M Steel Legend, To Be Filled By O.E.M.

11-26-2021, 01:49 AM #2I think I solved it! I used the SDIO link from the source forge project to update the driver. The one that previously worked is the AMD PSP 11.0 version. I'm still checking it later to confirm this fix, as I've been dealing with the issue for more than two years without a clear solution. Hope this helps someone else!
