I beleive it's normal dmasound doesn't work properly with it. "Tumbler" audio (whatever that is ;-))) [WWDC, Ben?] OK - could you send me the device-tree stuff? - and I'll compare it with what we've got. http://tibit.org/ppc/ has a nice (if somewhat slow) script that turns the dev-tree into html. With the BK _2_4 tree (and no other patches) i2s-a is checked and connected for output - *but* there may be a 'mixer-related' issue (because that's different too). I've fixed that up for the iBook (so that it doesn't try and do any AWACS-related stuff).... but that won't work for the new G4 necessarily. Iain ** Sent via the linuxppc-dev mail list.
