that I'd hit the red button at the bottom so as to record). This would suggest that the problem lies with Ableton, however I've selected the US 1641 as the Input and Output in the Ableton Preferences with no luck. Also, when I try recording on Garageband it both picks up the signal and records successfully. The Mac system settings are showing that the input from the interface is being received. I installed the latest possible US 1641 driver and firmware from the downloads page on the site. I dont think the problem is with the hardware itself. With the hardware, all inputs/outputs are seemingly fine, everything appropriately connected, all volumes turned up (headphones, mixer etc.).

I am not permitted to post URLs here as of yet due to site restrictions, but if you do a quick Google search you can find the product on the Tascam site along with the list of drivers/firmware that I have been struggling with. I'm using the Tascam US 1641 and Ableton Live. If anybody have any suggestions that would be fantastic, I seem to have exhausted every avenue!
