If you try them all and it still doesn't work, it may mean you have a half duplex sound card which means that it can't record and play at the same time. Sometimes a full duplex sound card may be shipped with a half duplex driver in which case one just needs to update the driver - that may be worth checking up on. With most Pcs, it is possible to install more than one sound card - so this is another possible solution if you need to get a full duplex one for recording.
Or get an external USB soundcard for a laptop. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
