Having a hard time getting BOTH AISO and/or EXCL working

I've spent hours trying to get this to work, so I can finally start taking measurements of my 5.2.4 setup. The only thing that I can get to work is the L/R and sub with standard Java, which does me no good.

I've read over all the posts I can find on here. Verified all my settings and nothing. I've tried 3 laptops, all with the same exact results. On my oldest laptop I got EXCL to work for a moment then it sounded like a quick pop and the sound went away. Couldn't to work again. The rest have no sound at all. When trying both AISO4all or flex I can eventually get sound, but it is very distorted. I tried all the different buffer sizes with no luck.

Can someone please help me!

Laptops: Surface Pro 9 win 11, HP Elitebook G6 win 10, Old Asus laptop win 10
AVR: Denon 3700h

If you aren't already, try using the latest V5.20.14 build. Using the Java driver, with an EXCL device, use the instructions in that post to obtain a log file, to upload here. If you aren't using a rear HDMI port on the AVR, try using a rear port. Are you using an actual HDMI port on any of the laptops, or a USB-to-HDMI adapter?

Using the latest build. I tried both straight HDMI and USB-C to HDMI. Always using a rear port (DVD) on the AVR. I will get logs when I get home.

I wonder if that was the latest csjsound build.

@djdanko1 : please use the attached csjsound dll (added version info output), and set the log level to trace in -DcsjsoundLibLogLevel=trace . The trace output log will be probably quite long.

So do I just copy this file to the REW directory? And do I add that line to the same place I did to originally enable logging?

Upon unzipping first. Just replace the existing dll file with this one.

Edit the line you added so that it reads =trace instead of =debug. It will produce more detailed logs.

Suface now seems to be working. (any errors you see about low sound is becaues I had the mic in the back room. I didn't feel like moving it to the listening area if it wasn't going to work) attached is the trace anyway. Going to try the Hp G8 now.

The G8 also worked, Very weird because I thought I had tried the new .dll from another post. Thanks for the help!! I'm excited to get started now.

Happy to hear all is working now. That really had to be some older version as the issue was fixed in June vhttps://github.com/pavhofman/csjsound-wasapi/commit/ee59abf96350fbf1bc2a6667802526942915444c . But the dll distributed with next REW build will report its latest commit to easily identify the version.

Hello. REW can use java driver for output and input devices in exclusive mode. This is a mode where the audio device cannot be used by anyone else. Right? Is this the same as wasapi? Or the same as wasapi event?

Wasapi event-driven mode is a method of using the API. The event-driven means the application thread waits for a wakeup event from the soundcard driver when complete buffer for/with new data is available, instead of periodically writing to/reading from the device the part of the buffer available at the moment of the call.

The EXCL mode in REW is wasapi exclusive event-driven.

If I select the Excl line, does that mean that no other audio device should access the audio data?

Thanks for answers. I missed this answer of yours. By selecting excl mode on my system, I can play a file in foobar at the same time as REW is running. Which shouldn't happen. Therefore there were my questions.

To the same device? And do you hear the two tracks merged?
I can play the sweep tone file that the REW generator created in foobar while REW does the measurement in 'from file' mode.
In addition, when measured through the laptop's internal sound card and java-wasapi-exclusive, the impulse is negative. And through ASIO and an external sound card it is positive.

REW does not use or access the output device when measuring in From file mode.
