New controls could appear during runtime, for example if a new firmware is downloaded to a DSP. Since ALSA drivers are not supposed to delete or renumber existing controls we can assume that any new controls will be after any controls we already know about. We can use this to enable extending our current list of controls, which is more efficient than closing the mixer session and recreating it.

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

To install these packages, run the commands:
sudo apt-add-repository ppa:taylorcholberton/tinyalsa
sudo apt-get update
sudo apt-get install tinyalsa
sudo apt-get install libtinyalsa-dev
