Resolves #182
The pop sound was caused by an error in the header size calculation. When a WAV file contained a unknown chunk, first the chunk type (4 bytes) is red, then the size (4 bytes) and after that is the chunk data. The 4 bytes indicating the size weren't added to the total header size. When seeking to the beginning of the sample data, it would seek to a position in the header before the data. The header was then parsed as sample data, which caused the pop.
Test file:
pop.zip
Can be reproduced with the speedy-player by changing the decoded file type to WAV.
