osspd (8)

osspd [options]

osspd implements the OSS devices (/dev/[a]dsp and /dev/mixer) in userland using CUSE. Sound data is forwarded to a DSP slave: Implementaions for PulseAudio and ASLA exist, but the ALSA slave should still be considered experimental.

DSP device name (default dsp)

--dsp-maj=MAJ

DSP device major number (default 14)

--dsp-min=MIN

DSP device minor number (default 3)

--adsp=NAME

Aux DSP device name (default adsp, blank to disable)

--adsp-maj=MAJ

Aux DSP device major number (default 14)

--adsp-min=MIN

Aux DSP device minor number (default 12)

--mixer=NAME

mixer device name (default mixer, blank to disable)

--mixer-maj=MAJ

--umax=MAX

maximum number of open streams per UID (default --max)

--exit-on-idle

exit if idle

--dsp-slave=PATH
