Most applications should work with OSSv4 out of the box. However, some distributions separate the OSS output plugins, or patch the software to use another sound API. This page will show how to tell some common applications to use the OSS API. There's no need to use any of these tips unless there's a problem.

  • Flash V9:
    • Note for Ubuntu users: do not install libflashsupport from apt-get. That version only supports Pulseaudio. Remove this package if you have it.
    • flashsupport.c is found in /usr/lib/oss/lib
      • 32-bit/x86 users should install SSL support libraries
        • In Debian/Ubuntu - sudo apt-get install libssl0.9.8 libssl-dev;
      • To compile: sudo cc -shared -O2 -Wall -Werror -lssl flashsupport.c -o
      • Then: sudo cp /usr/lib/mozilla/plugins
      • 64-bit/amd64 users should comment out "define OPENSSL" by placing a '#' in front of that line
        • To compile for 64-bit browser: sudo cc -shared -O2 -Wall -Werror -fPIC flashsupport.c -o
        • To compile for 32-bit browser, user needs gcc-multilib support
          • In Debian/Ubuntu - sudo apt-get install gcc-4.1-multilib
        • sudo cc -shared -O2 -Wall -Werror -m32 flashsupport.c -o
      • sudo cp /usr/lib/mozilla/plugins/
  • Gnome Volume Applet
    • Requires updated 32 bit version available from [1]

  • scummvm - MIDI music

    • Start timidity -Od -ir 7777 and then run scummvm. Select "TiMidity" as a music driver.
  • SDL
    • Debian: install libsdl1.2-debian-oss or libsdl1.2-debian-all
    • set SDL_AUDIODRIVER=dsp in the environment
  • skype
