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.
Building
TinyALSA uses Makefile as the primary build system.
To build and install with Make, run the commands:
make
sudo make install
sudo ldconfig
Installing
TinyALSA is now available as a set of the following debian packages from launchpad:

To install these packages, run the commands:
