Ok this is weird.

I have connected my gx4000 up to my cm14 monitor.

On Navy Seals I don't hear the bullet sounds but I hear the music. I am sure I heard it on the television.

The diagnostic test passes and I hear sound on all channels as I should.

Ok, the DMA sounds is silent on the diagnostic cart. WTF? I thought I heard the sounds on the television but not on the monitor.

Strange!

EDIT: Confirmed.

On television with SCART *all* sounds including DMA are audible.

On CM14, it appears some sounds are not audible. DMA sounds don't seem to be audible at all in Navy Seals. Silence, no bullet sounds, no collection sounds, no sounds in the test cart. Yet the sounds using AY in the normal way are so it doesn't appear to be a specific tone or noise. Really strange.

Scart connection is via GX4000 power brick. CM14 connection is using monitor connector and monitor power.

Perhaps it's my monitor... yet games otherwise seem fine.

That's weird because the audio goes to the SCART, CTM and stero Jack all the same. There is a stereo amplification which is driving all output.
Check your connection to the CTM or the CTM itself.

It was my error.

On the back there are 2 power connectors.

One is for power brick which gives 11v, the other for power from monitor at 5v.

You can't connect the power brick into both.

But you can connect the monitor power into either.

If you plug it into the wrong one the game works fine, but for some reason you don't get dma sounds, although ay and other sounds are fine and the game plays fine too.

I plugged the monitor power into the wrong one. Once I fixed that all the sounds came back LOL.

There is of course no point to a GX4000. Check out comedy genius Stewart Lee at 5.10 for his appraisal

Just in case you can't watch this video I thought I'd quote what Stewart Lee (The worlds 41st best stand up comedian) has to say about the GX4000 while appearing on the BBC

"If you're an impotant vesectomised, 45 year old, functioning alcoholic, father of two what is the point? Is there any point in you. You're a waste of air a waste of space. You are pointless. Like a three week old chop gradually going green in a hot room! or an Amstrad Games console! or Vernon Kaye"
