I have a fairly general problem when watching movies or tv shows on my laptop (MS Windows for 3 more days): I have about 40% hearing loss, and more volume is not the answer, because the loss is in layering, if you understand me. That is, I can't hear dialog with theme music playing at the same time. I assume the music and the dialog are often on different channels. Is there a Linux app that would give me more configurability? And yes, I am using fairly good earphones.
