Hola. I never had issues with the software, until the newer updates. The V 3.2.3 was very unstable. The newer 3.2.4 still the SoX internal chip, does not support the DSD upsampling at all, even setting it at DSD64. Using IZOTOPE upsampling at DSD256 I can play sometimes one or two tracks only the I get a crash. If I go to a previous version without SoX, the software works OK.
With the newer version 3.2.5 everything is fixed. Thanks!
