During gameplay and in attract mode, any sound involving voice not working (not there at all)

In test mode, sounds 1-10 come out barely audible, while 1-14 are perfect, and 15 is barely audible again.

Mystified. Any ideas or suggestions?

Example - when a ball drains down the outlane, it plays the appropriate little Russian number, but the "Hey!" that should be there at the end of the song is missing.

Just a shot in the dark but have you reseated both of the roms? I am unsure but does one control music and one control speech? Not 100% on that but reseating might be a first step.

Reseating the ROMS is good (be careful). Also see what kind of responses you get in test mode. The ribbon cable from the CPU to the soundboard is notorious for causing many sound problems, so you might try reseating it as well. Note that some sounds are generated by the CPU and mixed with other sounds and background music on the sound board. Per the repair docs "All speech is generated from the 55536 CVSD chip." http://level42.ca/files/PinRepair/System%209-11/Part2/index2.htm

When I lost all my speech sounds (the "HEY!" you mentioned) I found an open capacitor in the sound mixer circuit on the MPU.

Nice to see, my F-14 has been doing the exact same thing. Noticed the voice sounds were missing but some worked in test mode.

Should've read 10-14. I'll try that with the roms and the ribbon cable and report back, thanks!

Just a quick question. In sound test I have no sound for 00, 01, 05. All other sounds work fine. I don't want to hijack this thread. Just wondered if there missing sounds or not used test spots
