Audio device out - Audio driver not detected


I am trying to set up so that I can play three different mp3 files in three different audio channels to 3 speakers. I am using Focusrite Scarlett 6i6 with 3 speakers, connected to my computer via USB. In touchdesigner I have 3 Audio play CHOP, connected to 1 Merge CHOP, connected to an Audio device out CHOP.

As far as I understand, in order to get more than 2 channels I need to select ASIO as my driver in the audio device out CHOP. When selecting the default driver, the audio works but is only sent to 2 speakers. When I select ASIO as driver and Focusrite USB ASIO as the device I get the error “Warning: Audio driver not detected: ASIO1 unable to reset sample rate: No ASIO driver error” and there’s a very loud high pitch noise coming from 1, 2 or all 3 speakers.

The Focusrite control software is set up to send channel 1 to output 1, channel 2 to output 2 and channel 3 to output 3. I have tried to update the focusrite drivers and ASIO driver but no luck.

Any help is very appreciated, thank you!

I figured out why the driver wasn’t detected. There is an option to choose driver in the Audio play chop, but you can’t choose ASIO. So, I have to use Audio file in CHOPs with Audio Device out in order to do multiple channel audio.

That’s right, you can only open an ASIO device from one operator at a time so Audio File CHOP with Audio Device Out is the ticket here.


I just bumped into the same problem with touchdesigner 2022.33600.
I’ve got a MOTU Ultralite Mk5 connected, and I want it to output CV signals driven by Touchdesigner.
The .toe is really simple: Audio Device Out CHOP gets a constant signal, but I get these drops in the output signal (and in the CV too). See attached picture.

The warning says the same “Warning: Audio driver not detected: ASIO1 unable to reset sample rate:
The latest version of the MOTU Ultralite driver is installed. I tried also to use DirectSound but it does not output anything.
Anyone has an idea what’s going on?

You will probably still need to make the output match the devices expected sample rate, CV signal or not. So on the Constant CHOP’s channel page set to 44.1 or 48kHz, whatever your device is set to.

That should do the trick, thanks a lot for your help ben!
