# openalsink

This element plays raw audio samples through OpenAL.

Unfortunately the capture API doesn't have a format enumeration/check. all you can do is try opening it and see if it works.

## Example pipelines

     gst-launch-1.0 audiotestsrc ! audioconvert ! volume volume=0.5 ! openalsink

will play a sine wave (continuous beep sound) through OpenAL.

     gst-launch-1.0 filesrc location=stream.wav ! decodebin ! audioconvert ! openalsink

will play a wav audio file through OpenAL.

     gst-launch-1.0 openalsrc ! "audio/x-raw,format=S16LE,rate=44100" ! audioconvert ! volume volume=0.25 ! openalsink

will capture and play audio through OpenAL.
