Can't hear audio via Audacity...

I a running Yosemite 10.10.4 (14E46) (dmg) and have reinstalled Audacity 2.1.1 today as well as Soundflower 1.6.6 as I had these working before but not used for some time.

However, despite doing everything I believe I need to do to get the thing going to record a short thing off the internet, I cannot hear, or get Audacity to register, any audio.

About to ditch the lot and go the long way round with a recorder, but this used to work before. Any ideas?

Make sure you are following Recording Computer Playback on Mac OS X to the letter. Turn the Soundflower input and output up in Mac’s Sound Preferences.
