Yes. Sound system seems unstable. Another thing are stutters induced by incoming vox traffic and by "1st time" sounds (1st cannon, explosion etc). Already in AH1 I reduced HW acceleration to 50% otherwise loosing outgoing vox (sounds turning to a kind of "slow motion").
Yet all in all you do a good job in AH2 (FM, gunnery). Condsidering you are working with DirectX you do even an excellent job.
