I can't hear any sound playing back from my computer

- Ensure that your Saffire 6 USB is selected as the output device in your DAW or operating system sound settings (for system sounds).
- Ensure that the output channels that you are using correspond to the output numbers you are using on the back of the Saffire 6 USB.
- Ensure that the 'Monitor' volume dial has been turned up.
- If you are using headphones and are outputting audio to channels 1 and 2, check that the O/P 3/4 switch is not engaged under the headphone volume dial
- Check that your cables and speakers are working correctly. Try changing them or using them with another audio output.
