Last weekend, I've tried to use another audio wire (on the raspberryjamma) to make sure the problem was not coming from a faulty one. However there was still missing all the sound and music (except the announcer and the action beep).

Can you tell if the audio cable is fully going into the jack? The cable being out very slightly can cause a channel to drop due to the design of the connector.

If the audio cable is fine perhaps the DAC is the issue. I wouldn't think it's the RaspberryJAMMA side as it combines the stereo into mono straight away (except for the input jack nothing on the JAMMA board could cause a dropped channel).

I'll investigate further this week end.

By any chance, do you know if any game has a test menu with a stereo test?

Not offhand, I should find one though or just add a sound test to the service menu. I've been using Dragons Lair since discovering the bad audio cables in a previous batch of DACs.

I know it's old and I searched/read the other post but I still have an issues with Dragons Lair sound. Just one channel announcer with beeps - no sound effects. I've purchased 2 new DACs from Amazon and swapped out the audio cables with no results? I have tried multiple ROMS (original and the SE) with same results. I've tried with a speaker wired to jamma and via amp with same results. So - I pulled an Arpicade from my other cabinet and tired it an it WORKS fine. No issues. Could I have a bad Apricade??

It's not likely the issue is the RaspberryJAMMA (unless the 3.5mm jack is loose). Almost certainly the issue is either the DAC or the audio cable that came with the DAC.

To test this I'd try moving your good systems DAC over to the other and vice versa.

I stopped using generic DACs over a year ago now because every generic DAC i tried for 2 months had dual mono (left channel twice) instead of stereo. More than 100 DACs in a row with the same issue that I couldn't use... this is why I now only use Vention branded DACs. If you purchased generic DACs on Amazon this may be the issue, in which case you should return the DAC as defective (although it's a design fault).

I will order a new Vention branded DAC and update on results.

Appreciate the response.

Vention DACs is the fix!!!

Worked right out of the box. Hard to believe that all the other's are faulty.

Thanks dee2eR.

Yeah I had some interesting arguments with suppliers trying to return bulk purchased DACs with dual mono audio...

Hello, I purchased my RaspberryJAMMA between late 2017 and early 2018 (don't remember exactly) and I have the same problem with Dragon's Lair (no announcer vocal track).

Which device should I buy to fix the problem?

Maybe this one?

Thank you in advance
