Teppo units CTD

[Hanti]

Did somebody try using these units in battle? Everytime I try (campaign or custom battle) when they try to shoot it crashes. Any solutions?
Tried:
Shimazu Teppo Ashigaru, Teppo Ronin, Hojo Teppo Ashigaru, etc.

My version of mod: 2.8.

Test: crashing occurs when audio is on. Playing without sounds generate no crash.

The teppo units work fine, have you edited any f the sound files?

[Hanti]

No. I did not try messing with sound files. After some tests I found out that problem is with that files:
Gunner_Group_Fire_medium_03.wav, Gunner_Group_Fire_Large_01.wav, Gunner_Group_Fire_Large_02.wav.
If I remove them from bi\Shogun2\data\sounds\weapons\ that problem is solved.
