Windows has multiple levels of volume controls. How to set properly?
My W2K carputer uses an Audigy 4 board to send audio to my I-Bus head unit and thus pretend to be a cd changer.
The thing is, there are multiple levels of volume controls on Windows to adjust the line out volume:
- WAV level (I'm playing wav files)
- Master volume control
- WinAmp volume control
What combination of setting these will result in the best output sound quality?
I will be using a 1K Hz (-3db) test tone to set the input level to the head unit so that the level out of my amp matches the original level amp input level I set using the cdchanger playing the test tone.
I will be using the head unit volume control to adjust volume in actual use, I hope to get this to be a one time setup on the carputer side. Should I max the WAV volume, and maybe the master volume and use the winamp volume to adjust the line out? Should no control ever be maxed out, but always limited to 80%? What is the best strategy?
