I played a sine wave .wav file via DirectSound and it sounds perfect.

When I play it via ASIO however, it sounds really bad.

So I recorded my spdif output and dumped the waveform

this is what i see:


now, i took that "bad" wav file and i played it in directsound and it sounds exactly like what i hear from my asio.

so then i played my "bad" wav file in ASIO, and it sounds perfectly fine

is FMOD/ASIO stuff somehow doing something bad to DC offset of audio or something wrong with the max value sample (0x7fff)

the bug in the code was found and submitted to support@fmod.org

hopefully they will make a new build soon

4.06.15 and earlier exhibited the bug. i do not know about 4.07 and higher as they totally break my asio code
