nbmix for NetBSD - interactively control audio mixing
SYNOPSIS
nbmix [−d file]
DESCRIPTION
The nbmix command interactively displays and modifies various audio system mixing variables using a curses(3) based interface.
The nbmix command uses the NetBSD audio(4) interfaces directly, rather than using ossaudio(3) emulation.
The −d flag can be used to give an alternative mixer device. The default is /dev/mixer.

BUGS
No scrolling support: mixer elements that do not fit on the screen are not displayed.
Volume controls adjust all channels simultaneously.
Volume controls sometimes refuse to adjust. The controls adjust in step sizes reported by the audio(4) interface, but sometimes this step size is insufficient and upon the next poll of the hardware, the volume will fall back to the previous level. Usually, the volume can be increased by the user several steps before the next hardware poll, and so the change in volume will be sufficient. The author does not know if the hardware misreports the step size or if the audio driver is at fault.
