John Baldwin d0d4e34743 Add a new API for soundcards that have hardware volume control: ... - The mixer_hwmute() function can be called when a soundcard receives a mute request. - The mixer_hwstep() function can be used to adjust the volume of one or both channels. - The 'hw.snd.hwvol_step' sysctl determines the amount that mixer_hwstep() adjusts the volume by on each call. - The 'hw.snd.hwvol_mixer' sysctl specifies the mixer device to adjust the volume on for both functions. The values used correspond to the SOUNDCARD_MIXER_* constants.		2001-01-03 01:29:47 +00:00
