On the face of it, given the values above, sound should be correct on Iyonix. Having re-read the original eMail reporting the issue, it was "some games" that don't work, in particular Burn'Out and SimCity 2000.

Assuming SimCity 2000 is the PackMan release, then the common factor with those two games is they're setting RISC OS 3.71 emulation, which attempts to set the sound system to a known state.

To rule this out, try commenting out the ADFEmulateRISCOS{/b] line in the !Run.
