Configuring Applications for OSSv4

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:
  • Ubuntu: do not install libflashsupport from apt-get. That version only supports Pulseaudio. Remove this package if you have it.
  • flashsupport.c is found at /usr/lib/oss/lib
  • compile it with

 cc -fPIC -m32 -shared -O2 -lssl flashsupport.c -o libflashsupport.so

• • 64 bit users will require gcc multilib support.
  • If there's a compilation error, try removing the #define SSL line, and compiling again without -lssl.
  • Once libflashsupport.so is compiled, move it to /usr/lib
  • Run ldconfig
  • Restart browser

• libao
  • write default_driver=oss to ~/.libao

• mpg123
  • Debian: install mpg123 instead of mpg123-alsa

• MPlayer
  • write "ao=oss" to ~/.mplayer/config

• scummvm - MIDI music
  • scummvm 0.11.0 supports midi output via timidity.
  • 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
  • Arch: install skype-oss
  • install static OSS version from skype [1] (Direct link to 1.4 static OSS version: [2])

• sox
  • Debian: install libsox-fmt-oss

• wine
  • Debian: install libwine-oss

• xine
  • write audio.driver:oss to ~/.xine/config
