well, i had intermittent sound on my Alien Star, would not always be one, especially background sound. Seems to go on and off when jiggling the Driver board to Control board connector (new repro one) so i cleaned and reflow the connected of the Control board but now...
no sound at all, not a peep even when jiggling every connector so i assume i shorted something somehow on the board related to the sound?
Quoted from LTG:Any help here ?

LTG : )
Yeah I spent a lot of time on that page to get everything else refreshed, got new connectors all around, ground mod, etc...
The audio section is pretty general, it gives the path of the sounds with the MPU to driver board to sound but i am not sure how to test it end to end... I guess testing continuity across all chips maybe the best way?
