Hello, I am new to Arcade cabinets and I have two at the moment. Both of them have a CPS two inside with Alpha 2 on one and dark stalkers on the other. The alpha two cabinet one day after taking out the jamma and the a board and replacing of a dark stalkers, had started only playing audio out of my speaker and I’d confirm that it’s not the speaker that’s the issue. Now with more my most recent cabinet, I had gotten in it with a through a trade and only with the aboard included. The seller had Marvel versus Capcom and I was able to test and I can confirm that both speakers were working. Even after the ride home, both speakers had worked. They had forgotten the game and they had come to get it back themselves. I had done a trade and traded the Asian a bored that was inside because I wanted a US one. Now, after getting the game to load up, the left speaker on this cabinet as well it’s the only one that’s working and to top it off. I can’t raise the volume very high. It’s very very soft and quiet. Does anyone have any idea as to what can be going on? Thanks.
 
Try holding the Volume Down button while powering on... 50% of the time, that will reset the default volume levels.

Once the game has booted check the Vol Up/Down buttons are working in the Test menu.

If that doesn't work, CPS-2 sound issues are commonly related to the Supercap on the motherboard. Changing it out with a replacement should fix it.

If not, the issues will usually be deeper.
Where is it reliable place to get one of these batteries.
 
I had a volume problem with mine as well.

Went into the test menu, found sound, set it to JAMMA and max and it worked fine after. Might be worth checking that.

Also, if it's set to JAMMA, it's mono by default. You need to use the audio out on the back of the A board for stereo.

I’m trying to find where you found that I went to sound and voice. I can’t find anything else.In the test menu. Anyway, you can show me a picture of where you find that at?
