While I appreciate you offering a possible solution, it just feels WRONG for me to have try to re-config my perfectly fast reliable router to run, what seems like a VERY SIMPLE app.
If my 11 year old IPAD can run the program perfectly fine without ever having schizophrenic seizures with the volume control...why would I even remotely entertain the thoughts of possibly blowing up my EAR DRUMS up with an untested tablet. Sorry I don't agree with your answer.
I think you need to put everything down and just walk away. You are not ready for anything requiring any effort or trial.
