Libretto 50CT Volume Mixer

The Toshiba Libretto 50CT originally came with Windows 95. It was not meant to be used with MS-DOS, and it does not have a hardware volume control.

The Libretto uses an OPL3 sound chip that is Sound Blaster compatible—or perhaps the other way around, since Sound Blaster uses OPL3. However, compatibility does not extend to using Creative Labs drivers or tools.

Instead, BCCVOL provides a compatible volume mixer:

bccvol ?

Output:

Master volume level = 9
Wave volume level = 9
Synthesizer volume level = 9
CD volume level = 1
Line volume level = 1

A master volume level of 9 is far too loud. A much more comfortable setting is:

bccvol m4

This command can be added to AUTOEXEC.BAT.

BCCVOL is not a TSR, so it does not consume any conventional memory. Neat!
