I would like to suggest an additional option in the audio settings tab to specifically select an audio output device. This would allow a player to output game sound to a device separately from their default device selected in the operating system settings. There are several use cases why this would be very helpful. Most importantly for myself, it would allow me to isolate game sound for recording and streaming, so that alert sounds from other applications, streams I may be watching, or external voice chat does not get recorded. I expect that it may be useful in some home theater PC setups, or for people who have multiple speakers/headphones. While there are some workarounds in this area that can sometimes work, in a case where a person wants to handle two different applications' audio separately, and both those applications do not have discrete devices options, there is no way to separate their audio. I know linux systems have better OS audio handling, perhaps macs as well, but windows is not capable of per-application audio output device settings in the OS itself. I would love for KSP to be one of the good, quality applications that don't cause issues in this area.
