We may want to plug-in e2eaudiotest and others if already available. As of now, it frees the user from finding out the card, device info for each audio playback/recording device on supported hardware and can help in identify issues where audio is almost ok, but not truly perfect (like choppy audio). Un-attended tests may treat imperfect audio as bad as no audio. I hope I am able to convey what I intend to do so. thanks, Harsh

The e2eaudiotest tool was designed to be in a fully automated environment as a build sniff test that does not require a human to see if the entire audio stack on a particular board/build works "good enough" using a default path. The test script is to provide an interactive umbrella tool for the developer to exhaustively test the stack before upstreaming. This can include the former tool, but doesn't need to. > Yes, we can add more as well ! > > regards, > Harsh > > >> >> Thanks, >> Paul Larson >> > >

AudiVal (Audio Validation Suite for Linux) This is an attempt to automate and integrate various audio related tests which can help validate audio on various boards supported by Linaro. Motivation for this project comes from various audio tests listed at: https://wiki.linaro.org/TomGall/LinaroAudioFeatureIndex The git repo for this project can be cloned from: git://git.linaro.org/people/harshbora/audival.git Various files required by this script are available in the git repo. Requesting all to test this script on various boards that you may have access to and share feedback to make it better. TODO: Add tests for Audio over USB, Bluetooth.
