Problem with RODE Podcaster

I’ve got a macbook and RODE podcaster but can’t seem to get Audacity to operate. Keeps coming up with “error while opening sound device. Please check the recording device settings and project sample rate”. Have followed advice on settings but still getting nowhere. Anyone else experienced problems and/or know of simple fix?

Have you tried this FAQ: ? There are lots of possible causes listed there. For example:

in Finder, choose Go > Utilities > Audio MIDI In “Audio Devices”, select in turn the required Recording and Playback devices. Set “Format” to the same sample rate, bit-depth and number of recording channels as in Audacity.
