First of all I want to thank Darin for releasing latest version which fixed most of the issues I was experiencing except one so my question to those who have the latest version if you have any problems right clicking and scrolling down to reduce volume inside control panel. I have logitech g700 mouse and even unloading logitech software doesn't help. I would suggest to use Foobar2000 with SoX resampler for best results but if you want to use J River MC20 make sure you use Direct Sound instead of wasapi since converting 2 channels to 7.1
Hi Oleg,
I was able to find a Windows machine that has the problem with the master control volume down problem you reported. The levels can be moved down with the right mouse button, but the levels barely move down even if you move the mouse down fast. I am working on fixing that bug.
You can use WASAPI in JRiver, but you do have to have JRiver convert all the sampling rates to 24bit/48kHz in the DSP audio settings. You do not need to up convert from 2 channels to 7.1 in the traditional sense. With WASAPI, Out Of Your Head wants to see a 7.1 audio signal, but if you have a 2 channel source, audio is only sent on two channels. You can leave the Mixing setting set to "No upmixing or down mixing". Alternately you can use the JRSS function in JRiver to have JRiver up mix a 2 channel or 5.1 channel source to 7.1 channels to give you pseudo surround.
Here's the settings I use for JRiver and WASAPI Out Of Your Head:
This is the "Device Settings" window after you select Out Of Your Head WASAPI:
This is the "Tools/Options/Audio/Settings/DSP & output format..." window:
