Additional information:

SetVol ignores the case used in words

For example the following both set the volume level to 10 percent: 
    setvol ten
    setvol TEN

SetVol ignores the "%" symbol and the word "percent"

For example the following all set the volume level to 25 percent:
    setvol 25
    setvol 25 %
    setvol twenty-five
    setvol twenty-five percent

SetVol doesn't care if there is a hyphen between numbered words

For example the following both set the volume level to 35 percent: 
    setvol thirty-five
    setvol thirty five

You can use the balance, beep and report options together to verify individual speakers

For example on an eight channel device you can use the following commands:

setvol 50 balance 100:0:0:0:0:0:0:0 beep report

setvol 50 balance 0:100:0:0:0:0:0:0 beep report

...

setvol 50 balance 0:0:0:0:0:0:0:100 beep report

Here is an example of how to call SetVol via a .bat file and have it return the current volume:

call setvol report

echo %ERRORLEVEL%

Using SetVol with Windows PowerShell:

Unlike the Windows command line, Windows PowerShell requires that special characters be escaped.  The is done with the '`' character which is often found on the keyboard on the same key as the tilda character '~'.

So for example with the Windows command line where you might enter:

    setvol report device BenQ BL3200 (NVIDIA High Definition Audio)

with Windows PowerShell you would enter:

   .\setvol report device BenQ BL3200 `(NVIDIA High Definition Audio`)

where the open and closed brackets have been escaped.
