Digital distortion in REW

[Bergarth]

So I recently upgraded my CPU and mother board- still using my GPU I got months ago. When I try to Sweep for my subs i get a nasty digital distortion. After hours I solved the "sub" sweep 0-250HZ by cranking the sample rate inside preferences and using 1M as "length". And this is after swapping to every sample rate in windows etc.

But the noise is still there when sweeping full-range audio. Again ive tried every audio setting in windows 11- made sure no added stuff/enhancements was there.

Chain of devices-
HTPC- USB to MIniDSP-2X4HD
MIniDSP-2X4HD INPUT is from AVR- which i run with ALL enhancements anything off just straight audio. ( been perfectly fine for 5+Years)
I upgraded CPU to a i5 13400 and a decent mobo
Been using a 2060KO for months before changing CPU NO ISSUES

What drivers in REW? If ASIO try increasing the ASIO buffer size, or try the WASAPI exclusive drivers (device names starting EXCL).

@John Mulcahy The 5.20.13 release- I increased sample to 192- I dont see a "buffer" setting but ill have a look around.,

 

[John Mulcahy]

Are you using ASIO? If so the buffer setting is in the ASIO driver's control panel. Increasing the sample rate would usually make things worse.

@John Mulcahy Yes I am, Thanks Ill check that out!
