Source-Connect 4 Troubleshooting
The following page contains information that will help you troubleshoot Source-Connect 4 issues, including:
- A list of possible connection issues and links to the articles with troubleshooting steps.
- A list of the most common sound issues and links to articles with troubleshooting steps.
- A comprehensive list of error messages, notices and warnings for Source-Connect 4 Talent, Studio and Facility, and the Restore/Replace module of the application.
If you run into any issues not listed on this website, including error messages, please contact the support team.
Connection Troubleshooting
Disconnection issues are usually caused by severe network congestions occurring, or an unstable or insufficient WiFi connection. This can happen if you are inside a LAN where many other users are downloading and uploading large files. Reduce your bitrate, increase the buffer size and reconnect.
Read through the Source-Connect 4 network configuration and bandwidth article to review any requirements you might be missing.
Sound Troubleshooting
| Issue | Reference Article |
| Beeps in the audio | If you hear beeps in your audio, the problem might be related to clocking issues (see below "Clocking issues" section). Clocking issues are caused by sample rate conflicts. Make sure that your hardware devices have the same sample rate (this applies to any devices, including webcams, that you have connected while you are using Source-Connect). If you are a Mac user, check the Audio MIDI Setup to make sure all devices are set to the same sample rate your session has. If you are on Windows, go to Sounds > Recording/Playback > Device > Advanced instead. Beeping can also be caused by Wi-Fi dropouts, issues with your Source-Connect I/O plugin, or your hardware's buffer. Check the linked articles for more information and recommendations for any of these issues. |
| Buffering audio | Here is a link to an article on audio buffering in Source-Connect and how to improve your network connection to stop rebuffering. |
| Clocking issues | This is a link to a tips and tricks for Mac for Source-Connect and other Source Elements products. This is the same article, but for Windows instead. Specifically, tip 2 expands on understanding digital clocking problems. |
| Crackling audio | Crackling issues might be caused by incompatible devices either on the send or on the receive side. First, try connecting to the echo contacts. If you hear crackles, the problem is on your side. In essence, try disconnecting all devices other than your audio devices, and then plug them in one at a time to discover the culprit. Make sure your system meets the recommended network requirements listed on this page as well. Lastly, make sure you are using the correct audio driver for your audio device. If you need help with your audio environment, please contact our support team, which includes audio engineers. Focusrite ASIO USB Driver and Windows 11: the driver is known to have issues when used for Source-Connect in Windows 11. If you hear any crackling/distortion, download FlexASIO instead. |
| Echoes in the audio | Echoes in the audio are often caused by the other side of the connection. Make sure that you are using your headphones as outputs and not open speakers because your microphone will pick up everything coming out of the speakers and transmit that back. If you do need to use open speakers, then a talkback/push to talk switch must be used. Also, if you are using Source-Connect I/O or Source-Nexus I/O, make sure the routing is correct. If you are using a Yamaha Steinberg interface and you hear echoes, make sure to turn off the built-in loopback feature. |
| Fuzzy or distorted audio | These issues are usually caused by sample-rate conflicts or an incorrect audio driver on your device. First, make sure that your hardware devices support higher sample rates (this applies to any devices, including webcams, that you have connected while you are using Source-Connect). In addition, Mac users can also check the Audio MIDI Setup to make sure all devices are set to the same sample rate your session has. If you are on Windows, go to Sounds > Recording/Playback > Device > Advanced instead. |
| Interface drivers and compatibility | An issue between Source-Connect and your interface drivers might cause one of three issues (are two of them, in the worst case scenario): 1. You will have fuzzy or distorted audio. In that case, check "Fuzzy or distorted audio" in this table. 2. You might only be able to use your audio driver in one program at a time. In this case, contact our support team. |
| Intermittent audio | Most intermittency issues are caused by network bandwidth and configuration problems. Here is a link to an article including the minimum requirements and the recommended network requirements. Other causes might include an incorrect buffer (check the buffer size article here), or problems at the source of the audio (in this case, you will need to check with your connection partner to make sure there are no issues on their end). |
| Restore/Replace not displaying the recording | When the Restore/Replace tab does not display the recording in there, it is one of three: the watch folder has been set incorrectly, you have no more cached audio space, or there is a routing problem on your DAW. Check out one of our detailed how-to tutorials depending on your DAW - Cubase/Nuendo, Logic Pro, Pro Tools or Reaper. If you don't see your DAW in the list above, send us an email to support@source-elements.com with the name of your DAW, so we can create a detailed tutorial for you! |
| The Source-Connect I/O plugin | Here are some basic articles for Source-Connect I/O in the Talent version and the Studio/Facility versions. If Source-Connect I/O does not show on your DAW, check the following articles: Ableton Live, Adobe Audition, Cubase and Nuendo, Logic Pro X, Pro Tools, Reaper, Studio One, Cakewalk Sonar for Windows. If your DAW is not in the list, let us know, and we will add troubleshooting instructions. If the Source-Connect I/O plugin does not show up as an input or output in Source-Connect 4 and you are on macOS, make sure you have granted Source-Connect permission to your local network ("Privacy & Security" > “Local Network”). Additionally, please review the following two articles if you are having instability issues with Logic: the audio-unit is causing Logic to become unstable, or the Source-Connect I/O application shows a never-ending loading icon. |
| The Source-Nexus I/O plugin | Here is an article on the most common Source-Nexus I/O issues and how to solve them. |
