Found out also I can set some applications to the earbuds and others to the speakers! So a video can be playing on one set of speakers and the transcribing on the ear buds! And this was all setup almost instantly! Linux is quite miraculous! (The earbuds were normally used for working out. In particular work out vids.) (For transcribing I use audacity to get the exact notes at the exact time. Then export the 'labels' and use a python script to convert it to sheet music.)
