Does application playing sound at volume to 0% or mute make any difference to the performance ? or does it depend on the program. In my scenario, I always have application/games running then I leave the computer for few hours. If I set 0% volume / mute, does it save any power? or will the actual sound file still be processed in the application but I just can't hear it.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
If the application itself is muted, it most likely won't generate the sound in the first place, but set to 0% it might generate silence, sending data through the audio subsystem.
On the other hand, if the system is muted but the application is not, then sound data will still be sent from the application to the audio subsystem, but it will then be dropped. Setting the system volume to 0% likely has a similar outcome.
In all cases where data flows from the application to the system there will be a marginal performance overhead, however it will be so small that nothing but the CPU scheduler itself will notice.
