--- Comment #29 from Bruno Jesus 00cpxxx@gmail.com --- I think I found the issue, while playing the Excellent! wav file wine keeps reading data and gets to the next wav file header. The bytes it is trying to parse are exactly the RIFF text bytes from a wav header, since R (0x52) is > 0x06 the assert is triggered.
