Audio gets cut abruptly

[VIRGIN KLM]

I have a couple of samples in SSCF format directly ripped from games and they have the common SEDBSSCF header, possibly the header could have more intresting data which could lead to fixing the issue.
Also I don't know in what way VAG audio is different from Microsoft ADPCM, is the RAW stream any different at all?
VAG audio has been used since PSOne days and nothing got changed to the format at all so technicaly you could search for documentation in any PSOne/PS2/PSP/PS3 related wiki or something or atleast check JPCSP's code about it.
