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:
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:
| Package Name: | Description: |
|---|---|
| tinyalsa | Contains tinyplay, tinycap, tinymix and tinypcminfo |
| libtinyalsa | Contains the shared library |
| libtinyalsa-dev | Contains the static library and header files |
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]
