The tests in question are really for different audiences. 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, Its the initial phase and therefore will evolve with time as required.
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.

This script can serve as a unified interface to various audio tests that we
are developing.
Kurt (adding in CC) has suggested to plug-in e2eaudiotest into this as well.

Also, has it already been shown to work on all of the listed board?

It has been tested on Panda, imx6, Origen as of now, and the script works
as expected.
However, the tests obviously fail where audio recording is not supported by
underlying kernel.

Yes but that's not to say there aren't issues here and there for a

Cool, does this replace the existing e2daudiotest I guess? Also, has it

[RFC PATCH v1] AudiVal (Audio Validation Suite for Linux)

[Harsh Prateek Bora]

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.
