Q: Is there a testsuite?

Q: Is there a testsuite?

[P. Christeas]

Hello all.
I was wondering if there is some ALSA testsuite, that will detect if -my- 
soundcard covers all the ALSA functionality it exports with some X kernel.
From kernel version to version, some things get fixed, some break etc. Thus, 
it would be nice to run a simple program and wait to see if ALSA works fine 
each time..

There are some programe in alsa-lib/test/, but those are for testing
the ALSA library.

Sound card capabilities are too different to be able to create a test
suite that fits all.

You could create a script specific to your sound card that calls
aplay/arecord/amidi/aplaymidi/amixer/etc.

A test suite is well within the realms of possibility and saying
its not possible only discourages people from trying.

A generalised test suite would be of great benefit to the ALSA
project.

Right, but a problem is that the audio test is not always self
consistent.

Anyway, a set of sample audio data (or wave/noise generators) in
different settings (rates, formats, channels, etc) would be useful for
playback tests.  Any volunteers?

But the capture tests are more difficult (from the generalization
perspective)...
