I need my Windows 7 64 bit machine to output mono downmixed sound. Downmixed, not just single channel (I'm deaf in one ear). Is there any possibility to force such behavior. I'm looking for a software solution to mix two channels into one. I know that some media players have this functionality, but I'd like the whole system (ie games, flash applications, etc) to produce downmixed audio. (If none exist then just one for Spotify and Windows Media Player would be handy). Cheers.
