The other day I went to turn on the CPS2 multi and I found it to have no sound.

PROBLEMS:
1. No Sound
2. Sometimes after I flash a game, when it boots it gets stuck on the CPS OK, RAM OK, Q Sound OK screen (actually it hangs when it gets to Q-Sound and does not post OK)

TRIED:
1. Reseating A+B boards.
2. Reseating Darksoft Multi
3. resetting sound with volume buttons
4. Changed to another A-board still same problems.
5. USING both diagnostic ROMS which both PASS

I do not have another b-board to try the multi on.
every now and then when u boot it will have haunting weird sounds. or a loud SCREECH as it boots.
Voltage is at 4.82 / 12.0 which is normal when I used it before.

Any suggestions? Thanks everyone! <3

Bump your 5v up to 5v. 4.82 is well low and known to have caused issues before.

Also try another reputable SD card.

Try to reseat the interconnect board and also try using a decrypted set to rule that out.

My money is on the voltage being too low (also test it with a multimeter and don’t rely on a voltmeter).
 
-Voltage did not change the situation

-Decrypted set loads but no sound

- When loading Street Fighter Alpha 3, the DEMO will not go past the screen " BORN TO FIGHT" :: I can load and play the game but no sound.

- USED SanDisk 8gb and Kingston 8gb
 
Are you routing sound out of the CPS-2 over JAMMA or RCA. Whatever it is, try the other. Also make sure your sound settings are correct in the menu.

I’m assuming other games work on your setup?

What revision of the multi is it and where and when did you purchase?
 
Did you find the cause?
This is exactly the same as my multi kits issue, and I feel it's the sn74lvc4245 chips failing to blame.
 
i bought another CPS2 system A+B
i tried each arrangement
my old CPS2 works with sound
the new cps2 works with sound
but the multi provides no sound.
i bought the new CPS2 multi when i get it i will update the situation
 
I just fixed this exact issue by replacing the octal buffers for qsound. I have a heap of sn74lvc4245 chips spare if anyone else needs there kit fixed
 
@syntax_X i saw your new post. i think that could be it. check out my pics and tell me what you think
THANK YOU

i might need some of those chips!
