The controller is a HID-compliant game controller, it's supported out-of-the-box on Linux and applications accessing it through raw HID. I've bought Tegra hardware (nVidia Shield tablet and Jetson) and used to applaud their open source efforts, but screwing their game controller buyers like this makes me regret my decision. Excluding AMD and Intel graphics card owners has made a lot of people extremely displeased. NVIDIA previously released a driver that was bundled with GeForce Experience and only usable by NVIDIA graphics card users, and also suffered from a variety of issues according to forum discussions. It also emulates a force feedback device for rumble support in both DirectInput and Xinput games, tweaks the input data of the trackpad to make it usable, and adds support for the volume increment/decrement buttons. This small USB filter driver intercepts and tweaks the HID Report Descriptor to make DirectInput detect it as a gamepad. Support is planned but until then, the new model is already partially supported out-of-the-box by the generic Windows driver. This is a hardware limitation of the Shield.IMPORTANT: this driver doesn't support the 2017 Shield Controller yet.This is a known bug in the JRiver Android app that will be fixed at some point.I have a setting set incorrectly in the Shield or in the JRiver PC server.If I plug my PC directly into the same surround processor and play the same SACD rip the surround processor goes into 5.1 PCM mode and works exactly as expected. However, if I stream a 5.1 surround SACD rip, my surround processor stays in 2 channel PCM mode instead of going into multi channel PCM and sound only comes out of the LR speakers. If I stream a 2 channel SACD rip it plays perfectly. If I play a ripped blu-ray through the Shield that has Dolby TruHD or DTS HD-MA everything works perfectly.

The Shield is connected to my Emotiva RMC-1 surround processor. In the living room I have an nVidia Shield Pro with the JRiver app installed and connected to my PC as a library client. I have my JRiver library on my PC in my office.
