troubleshoot audio output

[rs232]

I have a 5.1 audio system, is there any utility (hopefully freeware) that can visualise the channel level in output?

Basically I would like to see the audio bar going up and down (reporting audio playback) for each of the channels while playing of course a 5.1 audio source.

Thanks
