Playing ULAW sample correctly?

Using the MCI, I've successfully played an ADPCM sample from Wikipedia, except
at the very end of IMA ADPCM play:
fixme:wavemap:wodWrite Not all src buffer has been written, expect bogus sound
After play status length increased from 13813 to 13826! How comes?

However, playing an ULAW sample, the same message occurs constantly (apparently
once for each wavehdr played) and the sound is awfully chopped. The error could
be anywhere (MCI, WAVE_MAPPER, gsm711 ACM, waveaudio ...).

Are there audio tests in Wine beside winmm/wave.c?
How is ulaw / how are the msacm/gsm711/gsm722/gsm602 tested?

Does anybody know whether ULAW works in Wine? (Any app that uses it outside of MCI?)
