All the sudden REW times out when generating sweep. Help

[JimJimmyJimJim]

I've been using REW on the same computer and the same stereo system for quite a while without issues. All of the sudden I'm getting an error message when I try to take a measurement or generate a sound. When I start "check levels" or generate a sound I get the following error message: Timed out waiting for space to write the fade out block to soundcard.
I've tried restarting the computer and REW but it made no difference.

Any ideas?

That could occur if the soundcard has stopped accepting data before REW has finished sending data to it. Which REW version are you using? What audio interface? How is the computer connected to the stereo system? What are your REW soundcard preferences settings?

Thanks for your reply.
I'm using ver. 5.31.3 running on my laptop with Windows 11. The soundcard is integrated into the motherboard.
For REW testing I use the laptop connected to my NAD preamp (old) via a line from the phone jack on the laptop. The preamp connects to two minidsp 2x4's (standard - not HD). The mini's connect to my emotiva amp and then to my LXmini's and two subs.
These are the soundcard preferences, except that the input would be set to the excl umik-1 with calibration card setting. I have been using this setup to make at least a dozen measurements in the past 2 weeks with no real problems until yesterday when this particular problem suddenly appeared. I have been using this basic setup for years (except for the REW ver. number) and, although I've had all sorts of other issues which I've successfully addressed, I haven't had this problem before.

Best using the Excl Realtek output device as shown in the soundcard debug rather than the default device as shown in the screenshot. Set the buffer sizes to 16k. Plug in the UMIK before starting REW.

 

[JimJimmyJimJim]

I'll give that a try and let you know. Thanks again.

 

[JimJimmyJimJim]

That got it going again. Thanks
