Jason Petho - sound error in Matrix

[Glint]

Hi Jason,
I'm playing a game in West Front with Matrix and moved a SPW S303 PzJg, armed with a 75mm Pak40 to fire at a Cromwell tank. The sound was that of a mg, not an AT Gun? The result was the Cromwell was disrupted so, I think the weapon is correct, just the wrong sound?
regards
Peter
