## Implemented Interfaces

GstOss4Sink implements GstStreamVolume and GstPropertyProbe.

## Description

This element lets you output sound using the Open Sound System (OSS) version 4.

Note that you should almost always use generic audio conversion elements like audioconvert and audioresample in front of an audiosink to make sure your pipeline works under all circumstances (those conversion elements will act in passthrough-mode if no conversion is necessary).

### Example pipelines

    1
    gst-launch-1.0 -v audiotestsrc ! audioconvert ! volume volume=0.1 ! oss4sink

will output a sine wave (continuous beep sound) to your sound card (with a very low volume as precaution).

    1
    gst-launch-1.0 -v filesrc location=music.ogg ! decodebin ! audioconvert ! audioresample ! oss4sink

will play an Ogg/Vorbis audio file and output it using the Open Sound System version 4.
