5. Troubleshooting

• Videos on YouTube refer to an Asio tab in Tools Menu. But I don't see anything in OBS !
  • There aren't any more on v2 and v3 of the plugin !
• I'm trying to capture the output mixes of my DAW (Ableton, Reaper, etc). But I don't see anything in OBS mixer !
  • This is an INPUT capture plugin; not an OUTPUT capture plugin. The ASIO sdk does not support it. For a workaround relying on virtual audio drivers, see this entry in the wiki.
• I'm unable to install the plugin
  • Check that you're using a version of the plugin which is compatible with your version of OBS-Studio.
  • Check in Program Files/obs-studio/obs-plugins/64bit that you can find win-asio.dll (v2.0.2+) or obs-asio.dll (earlier versions).
• The plugin installed, but when I launch OBS it doesn't show up in the list of sources. Also, there is an error message in the OBS logs that says 'LoadLibrary failed for '../../obs-plugins/64bit/win-asio.dll': The specified module could not be found.'
  • You may be missing a required C++ Redistributable. Try downloading and installing the latest one here: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
• Can I use asio4all on my non asio device ?
  • It's up to you. But people have reported stability issues and in terms of latency, it'd be better to use directly the WDM driver (wasapi). You won't have any gains in wrapping it in ASIO.
• My device is not recognized.
  • Make sure your device has asio drivers provided by its manufacturer, some lazy ones just provide asio4all !
  • If you use a USB interface, try to change the port and preferably don't share a usb hub for your audio device.
  • If nothing works, add it to the list of unsupported devices (which means that the asio driver is crappy; you'd be surprised by the number of audio devices with poorly written asio drivers).
• SUPPORTED AND UNSUPPORTED DEVICES (feel free to add yours)
  • See here
• My audio's crackly / disconnects / reconnects randomly
  • Check that your device's buffer settings aren't very low, some devices aren't stable at low buffer sizes. OBS has at bare minimum an internal buffer size of 1024 samples, don't worry about latency over stability pretty much any ASIO buffer size will already be significantly lower latency than any other type of driver.
• My audio sounds a bit weird
  • Check your devices sample rate matches that of the one in your output settings, obs resamples the audio for you otherwise.
  • Make sure to pick a format in the properties window which makes sense for the input you'd like to use/create, mono mics should be in mono format, obs will resample and mix the audio to your output. This may increase or decrease the output db. If you'd like to avoid resampling, match obs's output format.
