Ubuntu Dosbox audio error

Hi to everyone,
I ve always played swos 9697 on my Ubuntu system with Dosbox.
If I try to add the upgrade to season 2012/13 (or 2011/12) from Mega Pack the audio crashes.
If I upgrade the data folder everything is ok.
If I replace also the sws.exe file works only midi audio.
When the match starts with audio fx swos crashes.
It push me back to dos with this message:

SFX/PIERCE/m158_1_.raw
A:\

With the original sws.exe file everything is ok, exept some minor error (English Premier League and Italian Serie A are inverted).
So, with the new sws.exe I have to play without ingame audio.

It s because of my italian version of SWOS 96-97?
Is there a suggested SWOS version to download?

Thanks a lot to everyone who can help me.

Alessandro
