It is not actually needed, as there are other test which do something similar 
and break. The problem with most of the tests is: You don't know what is 
expected, so unless knowledged you won't notice the problem -  or did I miss 
some Documentation? I think because of that the tests are kinda useless, 
unless you know the code. (OK, you can still figure out, what should happen 
if you go to the code, nevetheless this is tedious.)

Perhaps it would be best if each test would output:

You should hear: ...bla....

My test is only quite "natural". Nevertheless, it is redundant.


BTW, I found some more oddities: The vorbis extension is broken. The test 
won't show it. Set looping to false and then you'll see the source won't be 
played fully. (mp3 extension works as expected though.) I tried to figure out 
what goes wrong, but so far I didn't succeed. Well I don't know much about 
OpenAL Buffering nor vorbisfile's callback interface.... Either samples don't 
get flushed out. (OpenAL sees input is done and stops playing, but vorbisfile 
has still samples to output, but that isn't flushed - my suspicion.) Or some 
other setting is wrong. (I don't know whether this is a regression. It would 
be strange if this was broken from day 1 though...)

Furthermore the testmultinothread sounds very strange. Is that expected?

What is furthmore bad: A lot of tesst use sample.wav which is adpcm and alut 
doesn't support it...

I changed most of the tests to the new alut interface, except the multichannel 
test, as it want to check # of channels. Is there a way to find this out when 
loading the sample in alut?


BTW; I think we should move this thread into devel. ;-)
