Hello,
I have been using Audirvana from 2019 the last year I have been subscribing to Audirvana Studio (AS).
I just updated to AS2.1 and after that on the same setup and same arrangement of drivers and hardware there is a noise present when playing back SACD.ISOs I did not try DSD files as I needed to use the software. This little “uppdate” sent me off for some hours to find a backup of the 1.9 version that still works when I uninstalled 2.1 and reverted back to 1.9
This picture shows the frequency response of the head of the first track of an ISO image that hold minimal audio data but the track has anyway started.
This picture shows the frequency response from approximately the same position on the same ISO… This is somewhat more of what I would expect to see.
What is broken?
I am soon to extend my license but frankly I will not do it unless this is working OR that there is any way to download older versions. Now I was lucky that I could revert to version 1.9 (10900) but most are not that lucky. I experienced identical problems in v2.0.4.0 that I also had laying around.
On a side note also related to SACD it seems to be a brick wall low pass filter @ app 22.1kHz. Why is that?.. it is easy to see in the noise of AS2.1 but when I playback in AS1.9 it is not much happening over 22.1k. Foobar for one even give a slight overshoot of noise up over 30-40k which would be nice to choose to have at least. Some of the tonal qualities that AS1.9 show is not there in Foobar but if I analyze my SACD player I can make the high end in this area to be just as unfiltered as Foobar is playing. Audirvana did play nicely ALSO up in this region in the past before possibly 3.1 of the old version. So, question is why is it not matching what a high end player does in terms of filtering?
Note, I do not believe hear the actual 20k + frequencies but I hear the limitation that it implies in the time domain. 
) I also limit the playback to 96k hence I only see up to 48k This is in order to be able to playback in a professional environment with external word clock. I have found that a stable clock is to prefer any day of the week beyond what the higher FS are doing when using internal clocks that leaves quite a bit to wish for. The SRCs are quite decent these days in these software’s.
This is unrelated to my problem as it is the same settings and the same system that produces these different results. The brick wall filter is however seen here quite clearly in the non functional 2.1
I enclose my debug data below of both 1.9 that works and of 2.1 that does NOT work.
Cheers,
