tinyalsasink

This element renders raw audio samples using the ALSA audio API via the tinyalsa library.

Example pipelines

 gst-launch-1.0 -v uridecodebin uri=file:///path/to/audio.ogg ! audioconvert ! audioresample ! tinyalsasink

Play an Ogg/Vorbis file and output audio via ALSA using the tinyalsa library.
