This could lead to playing out unwanted data which is placed at the end of file. authored-by: Patrick Lai <plai@codeaurora.org> Change-Id: I17bd3f6ebca4813f8987585472208c1f52696cae
TinyALSA
TinyALSA is a small library to interface with ALSA in the Linux kernel.
The aims are:
- Provide a basic pcm and mixer API.
- If it's not absolutely needed, don't add it to the API.
- Avoid supporting complex and unnecessary operations, that could be dealt with at a higher level.
- Provide comprehensive documentation.
