I replaced the CPU / Sound board in my RBION. Paul kindly created the ROMs for me (the board was missing from the machine). All works except I have no sound. I get a speaker "crack" on boot up but no sound whatsoever. Through the test menus not even the test tone works through the speakers. Cabling to the speakers appears fine....
I've checked all the ROMs and the appear to be seated correctly and the right way up (the other ROMs work so I assume I haven't done anything dumb here). I assume that the test tone should work even without the ROMs but not sure.
Reading through the manual (p26), it states "Voice ROMS U17, U21, U36 and/or U37 which are 8MB must have a jumper at W6 on the CPU/Sound Board to function properly. Not sure if this is related, but I assume I should get sound even if it was needed. Also, can't find W6 on the CPU/Sound board.
Any suggestions?
Thanks
