Frequently Asked Questions

+ +
    +

  1. How does Polypaudio compare with ESOUND/aRts/NAS?

    + +

    Polypaudio is sound daemon similar to ESOUND and NAS, but much more + powerful. aRts is a realtime-synthesizer-cum-sound-server, i.e. it + does much more than Polypaudio. However, I believe that Polypaudio + does what it does much better than any other free sound server.

    +
    2. + +

  2. What about ESOUND compatibility?

    +

    Polypaudio is a drop in replacement for ESOUND. That means: you can + load a esound compatibility module which implements an ESOUND + compatible protocol which allows you to use most of the classic ESOUND + compatible programs (including the command line programs like + esdcat).

    +
    3. + +

  3. Is Polypaudio a GNOME program?

    +

    No, Polypaudio has no dependency on GNOME/GTK/GLIB. All it requires + is a UNIX-like operating system and very few dependency + libraries. However, the accompanying GUI tools are writen with + gtkmm, i.e. require both GLIB and GTK.

    4. + +

  4. Can I integrate Polypaudio in my GLIB/GTK/GNOME application?

    +

    Yes! Polypaudio comes with a GLIB main loop adapter. You can embed + both the client library and the daemon (!) into your GLIB based + application.

    5. + +

  5. Can I integrate Polypaudio in my Qt/KDE application?

    +

    Yes! Polypaudio uses a main loop abstraction layer that allows you + to integrate Polypaudio in any program that supports main + loops. Unfortunately there is no adapter for Qt publicly available yet.

    6. + +

  6. I want to write a new driver for Polypaudio, are there any docs?

    +

    Currently, only the client API is documented with doxygen. Read + the source and base your work on a simple module like + module-pipe-sink.

    7. + +

  7. What about compatibility with NAS?

    +

    Is not available (yet?). It is doable, but noone has implemented it yet.

    8. + +

  8. What about compatibility with aRts?

    +

    Is not available. Since aRts is as synthesizer application you'd have to + reimplement very much code for Polypaudio. It should be easy to + implement limited support for libartsc based + applications. Noone has done this yet. It is probably a better idea to + run arts on top of Polypaudio (through a polypaudio driver + for aRts, which nobody has written yet). Another solution would be to + embed Polypaudio in the aRts process.

    9. + +

  9. I often hear noises when playing back with Polypaudio, what can I do?

    +

    There are to possible solutions: either make the polypaudio + binary SUID root (chmod u+s /usr/bin/polypaudio) and run it + with argument -r or increase the fragment sizes of the audio + drivers. The former will allow Polypaudio to activate + SCHED_FIFO high priority scheduling (root rights are dropped + immediately after this).
