the audio signal the green little thing at the bottom

That would be noise caused by something on your end not software related

That looks like a windoz volume/channel/mixer control with the volume set to max and input from that channel not having much gain???

Some more descriptive information about what you are doing and what you are doing it with along some context would help us help you...

I have an issue with REW on my laptop. It seems, when I try to use the inbuilt sound card with the signal generator, I get a wierd, noisy signal. However, when I try it with an USB soundcard, I get a normal one. On my desktop PC it works correctly, but not with my laptop. I have tried every single configurations to fix it, but nothing changed. The sound sounds faltering and fluctuate. This is visible on scope as well. When I'm playing a song with any kind of application, I get a perfect sound out of the sound card. I have tried different versions.

With Soundcard Scope application, I can get the expected sound waves out from the soundcard. What could be the problem? How could I fix this?

Soundcard Scope signal generator's output.

Check the sample rate and bit depth of the internal soundcard in the audio Properties, Advanced tab. Make sure the sample rate is that same as the rate you have selected in REW and the bit depth is at least 16 bit.

Obviously I started the investigation with this. But, it is very funny that it works with my desktop with any kind of configuration, works with a USB sond card. However, works badly with my laptop internal sound card and does not work at all with my NumarkParty Mix controller.

Quite strange. Maybe there is something odd with the driver for the internal card on that laptop.

Yes, it is strange indeed. But, I have the latest drivers, latest Windows 10. Soundcard Scope program produces sound perfectly. Music played perfectly. I suspect of the JAVA.

Definietely it must be something with the JAVA and with soundcard driver issue. -4dBFS and 0dBFS gave me the same level on the output. However, after a while, it's back normal.
Wierd.
Today I updated REW to REW V5,20 Beta 6 with JRE 1.8.0_192 64bit. It was required to install other Java. Now, it works normally. Thanks! I like this software.
