We usually don't see music production equipment here, so chances are very low to find another user of this hardware.
Anyway, there are some facts about USB audio and LE. Generally spoken, the higher the audio data rate, the lower the chance that an USB DAC will work. LE is no real-time kernel system, which will make USB transfer slower - too slow for some audio formats. Current user reports say that AC3 is kind of a breaking point: Audio formats below such a data rate work, AC3 and better doesn't work.
NI is a company for professional musicians, so I bet your device wants to receive USB audio data by using a pretty high data rate. If you find settings to reduce audio data quality, give it a shot.
My advice is to forget USB audio, and use an HDMI audio splitter instead. Then connect your NI device by using a cinch cable.
Thanks. The other idea I was thinking of was to get a HiFiBerry DAC that would plug into my raspberry pi.
That's an option, but the HDMI audio splitter is the more universal tool, often has optical output and might be cheaper. The only bad thing I heard about those splitters is that some of them don't pass-through CEC signals.
PS: Don't expect to get all audio formats (incl. AC3, HD audio etc.) when using a HiFiBerry DAC. The RPi's data bus will set some limits, too.
Do you have a link to the type of HDMI splitter you're thinking of? Is it something like this: eSynic 1080P HDMI Audio Extractor Splitter HDMI to HDMI + Optical TOSLINK SPDIF + Analog RCA L / R + 3.5mm Stereo Audio Splitter Adapter Converter for TV Blu-ray DVD Player SKY HD Box PS3 PS4: Amazon.ca: Cell Phones & Accessories
I don't suggest it. It's not future-proofed, because it doesn't support 4K. I found this splitter, which supports 4K and CEC: FeinTech VAX00102.
PS: If you additionally buy a 90 deg. angle adapter (Ebay) and use a 90 deg. power plug, then you can do a 180 deg. turn at the front of this splitter. So your studio desktop will look well-organized. The ability to switch off video while still having audio is another plus for a studio.
