Loud hissing noise while playing

[Bassquake]

Tested Pink Floyd Dark Side of the Moon SACD on this, and get a loud persistent hissing noise throughout.

Using Windows 10 (2004) 64bit Matrix 19.0 version and the 0.1.2 SACD encoder addon to an Onkyo HT-R390 reciever.

Attached a sample of the issue.

Edit: Hiss goes away if set the Output Configuration to Fixed rather than Optimized or Best Match. And also set Limit Sampling rate to 96 or below (higher and it hisses again). Hope that helps in tracking down issue as didnt need to do this on the Leia build.
