How to set up a DAW with OBS on Windows
OBS ASIO Plugin
Set up an ASIO Source
Please note, the odd-numbered inputs (1, 3, 5, etc) default to sending to the left channel, while the even-numbered inputs (2, 4, 6, etc) default to sending to the right. If you are trying to send a mono signal out, use a stereo output to send it centered.
We do not recommend trying to monitor your feed from inside OBS or on the Volume website, as there is an inevitable latency that could make it difficult to play along with.
Another great solution to sound-forwarding is Voicemeeter Banana. One can install it here. Once installed, it's very important that the user restarts their device.
Once the setup is complete and the device has been restarted, one may go ahead and set their sound output to "VoiceMeeter Input." Here we are effectively routing desktop audio into Voicemeeter (it will show up in the VAIO section)
Once that is set, one can now open their DAW, go to the audio output settings, and set the output to "VoiceMeeter Aux Input." This sets the output of our DAW into an auxiliary track in Voicemeeter, Voicemeter AUX
In OBS, add an audio input capture, setting the device to VoiceMeeter Aux Output. In this step, we are making sure that whatever we route into Voicemeeter's AUX channel will also go to the aux output
Finally, we need to tell Voicemeeter what we want to be routed. In Voicemeeter Banana, enable B2 for Voicemeeter Aux in the Voicemeeter Virtual Input Section. This ensures that whatever is going into the AUX channel is sending the signal to its corresponding output. If we want desktop audio, we can enable B2 for the VAOI virtual inputs. Similarly, if we want some sort of hardware input (ie. a microphone) to go through to OBS, we can directly do that by enabling B2 for each hardware input we want.
