This could be a Windows driver problem. RMAA, even older versions, works fine for me (as far as it can be considered working fine for any purpose, with the usual bugs and limitations) on Linux with WINE at high sample rates, emulating the old Windows MME audio API. The same is true of Visual Analyser, which I find rather problematic to use on native Windows (it is surprisingly hard to make the system not resample the audio signal, sometimes even more than once, or to get 24-bit recording that is really 24-bit), but do not get the resampling problems with WINE.

Generating a sine wave (or multiple tones, for that matter) should be simple with any suitable software, as is creating an FFT plot of the recorded audio. Although having an automated test suite like RMAA is obviously more convenient. :normal_smile :

Exactly. Interestingly, REW and ARTA have less problems using the ASIO driver and run all the way to 96 kHz. 

 

I have Ubuntu Studio with another laptop and it runs great. The laptop I'm using right now however tends to overheat probably due to the video card Linux drivers. That said, music and stuff through ALSA was very nice and less problematic.

 

LOLs! There are many ways to skin a cat.
