It seems like you are encountering issues with your audio interface and its compatibility with Ableton Live 10. Here are a few steps you can try to troubleshoot and possibly resolve this problem: 1. Update Audio Interface Drivers: - Ensure that you have the latest drivers and firmware for your Behringer U-Phoria UM2 audio interface. Visit Behringer's official website to download and install any available updates. 2. Select Audio Interface in Ableton Live: - Open Ableton Live and navigate to the preferences/settings section. - Select the Behringer U-Phoria UM2 as the audio input and output device within the audio preferences. 3. Check Audio Settings in Windows: - Go to Windows Sound settings and verify that the Behringer U-Phoria UM2 is set as the default playback and recording device. - Ensure that the sample rates and bit depths are configured correctly to match the settings in Ableton Live. 4. ASIO Audio Driver: - If possible, use ASIO drivers with Ableton Live for low-latency audio performance. Check if Behringer provides ASIO drivers for your audio interface and configure them in Ableton Live. 5. Restart Audio Services: - Sometimes, restarting audio services can resolve issues with audio playback. Open the Run dialog (Win + R), type "services.msc," and press Enter. Restart the Windows Audio service. 6. Buffer Size Settings: - Adjust the buffer sizes in both Windows sound settings and Ableton Live. Lower buffer sizes can reduce latency but may require more processing power. 7. Check Ableton Live Preferences: - In Ableton Live, ensure that the audio settings match the capabilities of your audio interface, like sample rate, buffer size, and input/output settings. 8. Test Different USB Ports: - Connect your Behringer U-Phoria UM2 to different USB ports on your computer to rule out any port-related issues. If these steps do not resolve the issue, you may want to consider contacting Behringer support or Ableton Live support for additional assistance and troubleshooting tailored to your specific setup.
