My spark 40 amp is plugged into my PC and my pc recognizes it as I use it as a desktop speaker and play along to jam tracks etc with it and have no issues with setting my tones etc. I downloaded cakewalk to start recording. It shows my spark 40 as an input, but when I hit record and start playing.. nothing. I'm not sure what I'm doing wrong or what settings I need to do or if theres some process to actually start recording my guitar, but cakewalk records nothing, it shows as recording, it counts the time, but when i stop the recording and go to listen, theres literally no difference to the screen, it looks exactly as it did before I hit record, and when I hit play nothing happens, theres nothing to play. Can someone help me with this?
