However, being able to adjust the relative volumes of the different channels still seems useful to me. If you have a single unified control, then you mess up trying to move the others. What do you think? Should I just slave them all together and remove the other volume controls? It's probably easier; it just seems somehow lacking. -- Daniel Jacobowitz CodeSourcery ------------------------------------------------------------------------- Take Surveys. Earn Cash.
