A600 Strange Audio Stutter on DH0 IO

[brownb2]

I don't know whether this has started happening since I upgraded to the ACA620 but I'm noticing games like Cannon Fodder 1/2 audio stutters / cuts out completely whenever the DH0 access light goes on and resumes when the light goes out.

Now admittedly I've not used the Amiga 600 in a while but I remember it could do parallel IO - anybody any ideas what could cause this problem?

For what it's worth Turrican 2 now crashes out right and Turrican 3 also has the same music problems and crashes intermittently.

After checking the max transfer settings I can only think that it's a problem with the old CF card I'm using for DH0 so I'm currently reinstalling it to a new internal CF card.
