Is it possible to make certain processes to not have access to my sound card ?
Let's say i have 2 processes running: firefox and my music player and i want to make sure only my music player can produce sound..
I imagine there must be some sort of request from the application to the sound card to "acces the sound card" (perhaps via drivers?), so i could basically redirect all requests that don't come from my music player to /dev/null (i'm in ubuntu). Perhaps this is possible with some shell script or C script ?
