Question / Help Allen & Heath QU-16 Digital Mixer via USB - No Sound in OBS

[SHMBC]

Hey all, sorry for the repost but I changed the title and have been waiting hours for a reviewer to 'okay' it.

So, here is what's up: Been using OBS for about two years and have had a few issues with sound but have figured out either the root cause or implemented a workaround - until now.

• The QU-16 is now connected to the PC 100% via USB.
  • Previously, I had it connected through an analog cable (Old school into the LINE in jack)
• Windows sees the QU-16 as both an INPUT and OUTPUT device under SOUNDS>PLAYBACK and RECORDING
  • PLAYBACK of audio from the PC is sent to the QU-16 and is audible through the attached speakers. Check!
• On the RECORDING tab, when speaking into the mic in the QU-16, I can see input on the LEVEL indicator. This shows that the PC sees the INPUT source from the QU-16 via the USB.
  • In OBS: There is no input from that same source - the levels do not show any input whatsoever.
  • This occurs whether the setting is on MONITOR OFF, MONITOR ONLY or MONITOR and OUTPUT - Nadda.

With that, I am STUCK. I do not see any (even somewhat obvious) reason that it should not be capturing the audio from that source since Windows recognizes the USB source.

We use OBS to not only stream to our YouTube channel but mainly for our members who may not be able to attend that day, so having no audio is paramount. We can get be when we have no vid feed, but no audio is altogether different.

HELP, please!

Thanks!

OBS is a stereo program that also supports surround audio. To use a multichannel audio device with it, you may need either a DAW or something like the OBS-ASIO plugin. I'm guessing that whatever you're putting into the mixer isn't getting to channels 1/2 like OBS expects.

Oh man, you guys saved my butt after 2 days of messing with this. I found some really crappy workarounds using virtual audio adapters to circumvent the QU (Line) device not coming into OBS which added tons of latency. The ASIO plugin worked like a dream! I still get the slightest bit of latency that is perceptible when using the monitor function in OBS (but nowhere near as bad as using virtual audio cable routing in windows), but if I feed the mic input and monitor through the board, its zero latency. Only when I try to monitor mic through OBS, I get the slightest echo.
