No sound coming out of Ableton Live 8.27

[AntAir]

I got a new Bronco 40 Amp, and successfully plugged it into the computer to record and such. However, Ableton has no audio. The test tone doesn't make a sound, there is no waveform after recording, and there is no sound when monitoring is turned on despite it clearly displaying that sound is coming through. I'm using ASIO, Realtek Drivers, and Windows 7 64-bit, all with the latest updates. Suggestions?

I have a similar problem.

I updated ableton to version 8.2.7 and afterwards, ableton has no sound. Worked fine before the update.

Any ideas how to fix it?
