Playback is too fast with m-audio fast track pro

I just bought a new macbook air version 10.12 and imported everything to it from my macbook pro. When I record a track using Audacity, the audio plays back at about 1.5x the speed of the original. I did not have this problem before. I’m recording my music via m-audio fast track pro interface with the latest drivers for mac (version 10.10) as well as installed the latest version of Audacity. I tried using different sample rates but that didn’t cause anything to change speed-wise. Any help would be appreciated. :smiley:

Make sure you are using explicitly Audacity 2.1.2 from The “latest version” on other sites may not be 2.1.2.

The sample rate in Audacity project rate should be a rate supported by the device. Do not exceed the maximum sample rate specified in the M-Audio Control Panel.

Then set the exact same rate in /Applications/Utilties/Audio MIDI Setup.

If you are overdubbing, the Audacity track rate should be the same as the project rate.
