For various definitions of "working". I plugged my speakers in to the headphone and speaker sockets down the side and do get some sound, but I need to turn my speakers to about 75% to hear anything at all (and yes, the volume sliders on the MVS are both on max ). Also, the sound I do get is very static-y and generally not very clear. I think I've read about this problem before, so will take a look around to see if I can find more information on a solution. Actually, I just got two of the 15-pin D-sub connectors from Maplin (I was ordering stuff from there anyway). Cutting off some of the housing looks like it'll be more trouble than it's worth, so I'll just take the sensible route and buy an extension lead to modify. I can't believe I didn't think of that before...
Sounds like it could be a blown amp. Let me know if you can't get it working and need it looked at ;-)
Good news, everyone. It turns out that my lack of sound was due to me being incompetant. Hands up if you saw that one coming... As I had read elsewhere on the interwebs, the 3.5mm jacks down the side are not in fact for heaphones or speakers. Not sure why I got sound from them in they're line-in ports, though. Nor why it needs them at all, but nevermind. Instead of taking the simple route of hooking up the four-pin sound connector (which is next to the 3.5mm jacks) to some phono leads, I decided to wire up a 3.5mm jack (one which I had ripped from a dead CD-RW drive only the week before) to the MVS to JAMMA adapter I built. Now I have sound and all is well. Quite an amplifier it has, though. When I first tested it, the "Speaker" control (the one which controls the volume going through the edge connector) was on full - I plugged in some cheap in-ear style earphones (think those terrible iPod things, but much better)... The sound was heard throughout the house, I kid you not. This is from tiny earphones, I remind you. Thankfully they were not in my ears at the time (I've learnt from previous mistakes...). I had to push the slider all the way to a position very near "off" to get a usable level out of it. The only remaining "problem" is the joysticks - or lack thereof. I've got myself some nice extension leads and attempted to hard-wire an old PSX controller to a 15-pin D-sub connector (saves me from butchering perfectly good cables). I got the direction pad sorted, but accidentally removed a little much of the strange black conductive stuff from some of the other buttons. One PSX controller gets to visit the bin. No great loss there, but it cost me a few hours. Still, I know to be more careful next time. Also; that fibreglass pen is great for stuff like this - really glad I bought one.
Nice results. I too am getting nothing from the 3.5mm socket (which is a line out as it's on the Vogatek) but the PCB isn't passing audio through the Jamma which it's supposed to. Looks like I'm gonna have to make a plug for the header on the PCB.
Fibreglass pencils are great, but be VERY careful with the 'dust' and how you dispose of it. It is an irritant. Twimfy, what board? If its a Neo Geo / Ultra64, some don't pass sound through the JAMMA connector.
The Hyper has two dips on the bottom. One allows you to switch the whole board between MVS and JAMMA the other allows you to choose MVS stereo or JAMMA Mono. I have plugged a speaker into the 3.5mm jack on the vogatek and no matter which setting I choose I can just hear white noise, the volume of which can be turned up and down using the volume pot. I tried connecting an old PC speaker to the connector I made for the audio header on the board but no sound from that either.
Nah, SOME hypers do, but not all. You don't want to be one of the lucky ones with an old, non-JAMMA board! heh. In which case, you'd just have to make a header, unfortunately.
Take a look at the picture. On the left there is a beige small four pin connector. On the wiring diagrams it is -L -R +L+R audio. I have no idea what the black clip socket on the right is for.
Are you sure that's sound? I seem to remember on the early ones, it was the square 4 pin molex on the end. The manual says the sound header is 8 pin, the others being +5V and ground.
Thankfully, the Maplin page for the fibreglass pencils explains this, so I've not had anything bad happen thus far. There's still time, of course. I keep a damp tissue available for collecting the dust, dabbing the board when it starts to pile up. Blowing the dust away seems like a really bad move (not tried it yet - don't intend to). Thanks for the warning, though.
No worries - don't want anyone doing themselves/family/pets any damage! The damp tissue is a good idea. Blowing it away would be awful - it'd probably come back in your face, plus it'll distribute and could be picked up by others easily!
eh? my vogatek gets sound through the jack. All my jamma games give sound through it and even my mvs gives mono sound through it. Stereo sound I take out of board pins weird your pins are negatives on the left side. My mvs has the negative lines as the two pins on the middle
