video source with 2 audio channels

[mo_jai]

Hey so i have a few video karaoke sources with 2 audio channels, the left side is the vocals and the right side is just the music. So when i play it on my computer, and i choose the right audio track for karaoke, only my right speakers will have sound. How can i play it so that i can choose the right audio track for karaoke but output it to both my speakers?

Use a player such as MPC-HC which allows you to use ffdshow to decode the audio. You can use ffdshow's volume filter to mute the left channel, then set the mixer filter's speaker configuration to mono. That should output just the right channel in both speakers.
