How do you calibrate your TX out audio in linux??

[grobin]

In Windows we can all download checkSR.exe program (included in the MixW install) and that works fine.  But how do you accomplish the same in Linux?  I run Ubuntu on a dual boot with Windows right now so the only way I have done it is to run checkSR.exe in WIndows and use the figures it reports.  CheckSR.exe does NOT run properly on Ubuntu via WINE (emulation) for me so that is not an option.

Does anyone know a native Linux program that does the same thing CheckSR does?
