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.

TinyALSA supports these build systems:

• CMake
• Make
• Meson
• Soong for Android

To build and install with Make, run the commands:

make
sudo make install
sudo ldconfig

TinyALSA is now available as a set of the following Debian packages from launchpad:

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

Once installed, the man pages are available via:

man tinyplay
man tinycap
man tinymix
man tinypcminfo
man libtinyalsa-pcm
man libtinyalsa-mixer

To test libtinyalsa, please follow the instructions,

The test program does pcm_* operations on loopback devices. You have to insert loopback devices after your system boots up.

sudo modprobe snd-aloop
sudo chmod 777 /dev/snd/*

bazel test //:tinyalsa_tests --test_output=all

The default playback device is hw:2,0 and the default capture device is hw:2,1. If your loopback devices are not hw:2,0 and hw:2,1, you can specify the loopback device.

bazel test //:tinyalsa_tests --test_output=all \
    --copt=-DTEST_LOOPBACK_CARD=[loopback card] \
    --copt=-DTEST_LOOPBACK_PLAYBACK_DEVICE=[loopback playback device] \
    --copt=-DTEST_LOOPBACK_CAPTURE_DEVICE=[loopback capture device]
