OSSPD(8) 💖

okay bestie, welcome to the osspd page — that's the OSS Proxy Daemon, and it lives in the System Manager's Manual section. 🎀 Let's get into it.

✨ NAME ✨

osspd — the OSS Proxy Daemon. that's it, that's the name, she's iconic 💅

🌸 SYNOPSIS 🌸

osspd [options]

🦋 DESCRIPTION 🦋

so basically, osspd is out here implementing the OSS devices — that's /dev/[a]dsp and /dev/mixer — in userland, using CUSE. no kernel module era, we're doing it from userspace, slay ✨

and then the sound data? it gets forwarded to a DSP slave. there are implementations for PulseAudio and ASLA, but listen — the ALSA slave should still be considered experimental. so like, cute but maybe don't build your whole personality on it 🙈

💖 OPTIONS 💖

  • --dsp=NAME — the DSP device name (default is dsp). ✨
  • --dsp-maj=MAJ — the DSP device major number (default is 14).
  • --dsp-min=MIN — the DSP device minor number (default is 3).
  • --adsp=NAME — the Aux DSP device name (default is adsp, and blank disables it).
  • --adsp-maj=MAJ — the Aux DSP device major number (default is 14).
  • --adsp-min=MIN — the Aux DSP device minor number (default is 12).
  • --mixer=NAME — the mixer device name (default is mixer, and blank disables it).
  • --mixer-maj=MAJ — the mixer device major number (default is 14).
  • --mixer-min=MIN — the mixer device minor number (default is 0).
  • --max=MAX — the maximum number of open streams (default is 256). keep it reasonable bestie 💀
  • --umax=MAX — the maximum number of open streams per UID (default is --max, so like, whatever you set above). 🫶
  • --exit-on-idle — exit if idle. she's not sticking around if nobody's talking to her, periodt ✨
  • --dsp-slave=PATH — the DSP slave (default is ossp-padsp in the same dir).
  • --log=LEVEL — log level (0..6).
  • --timestamp — timestamp the log messages. so you know when things happened 🕐
  • -v — increase verbosity. and yes, you can specify this multiple times, stack her up 🔥
  • -f — run in the foreground (i.e. don't daemonize). main character energy, stays right there with you 💅

👑 SEE ALSO 👑

if you want the more technical documentation describing some of the inner workings, it's living at /usr/share/doc/osspd/README.gz. go read her, iykyk 📖

and that's the whole page, bestie! this was osspd 1.3.2, dated September 2012 — shoutout to the System Manager's Manual for hosting her. mwah, bye! 💖✨🎀🦋🌸💅
