JSI Tip 6477. When you attempt to adjust the volume control slider in Windows 2000, the slider moves to the lowest level?

If you experience the subject condition, your sound driver may have improperly set the Enable HW Volume Control Value Name to a data value of zero at HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass\{4D36E96C-E325-11CE-BFC1-08002BE10318}000.

If your data value is zero, run the following HWVOL.BAT file to set it to one:

@echo offsetlocalset key=HKLMSYSTEMCurrentControlSetControlClass\{4D36E96C-E325-11CE-BFC1-08002BE10318}000@echo Retrieve "Enable HW Volume Control"for /f "Skip=3 Tokens=5" %%i in ('reg QUERY %key% /v "Enable HW Volume Control"') do set type=%%iIf "%type%" EQU "REG_BINARY" goto HWVOL1BIf "%type%" EQU "REG_DWORD" goto HWVOL1D@echo Not found or bad data type.goto :FINISH:HWVOL1D@echo Set REG_DWORDreg ADD %key% /v "Enable HW Volume Control" /t REG_DWORD /d 1 /fgoto :FINISH:HWVOL1B@echo Set REG_BINARYreg ADD %key% /v "Enable HW Volume Control" /t REG_BINARY /d 01 /f:FINISHendlocal

NOTE: You must restart your computer for the changes to take effect.
