I have "Dummy Output" in my sound settings. I am fairly new to Linux, however am fairly computer literate. I LOVE Linux, so I would really prefer a solution as opposed to going back to Windows which I hate.
My sound card is a HDA-Intel "Realtek ALC3235".
Also, I have a touch screen (which I don't really use, I use the keyboard) laptop and with one of the upgrades came the problem of the mouse jumping all over randomly while typing. Anyone have a solution for that?
alsamixer
