Hi all. I am no longer able to use Audacity to record system audio as I once was. The M-Audio card I used to have worked w/Audacity just fine for a long time, but I can not record anything with my new RME HDSPe AIO. I have tried every single option available, but nothing. Using W7 Ult 64-bit and Aud v2.
You also need to route the channels you want to record in Totalmix. Hit the X key and set the number of inputs you need. Then open Audacity and select the RME for input and output.
You M-audio is a very simple thing, compared to the RME that allows you to route anything to anything, including system audio. In Totalmix, you’ll get inputs and outputs, but also software playback. And all of that can be mixed and routed anywhere.
