A1200 sound issues

I've tested it with a few games I know well. But I'm going to test it with a tracker too, but I'm sure it'll confirm the symptoms I've found.

Two channels are missing. Both left and right output on the amiga works, only in games I can only hear two channels, one in each (left+right). So I only get half of the music, or no sound effects. It's really anoying and a little scary...

What should I look for in the patient? What might be wrong here?
This machine works all fine except this thing. It's accellerator works (sound is still a problem with it removed), and floppy + joystick + mouse all else is fine. But still only "half" the sounds it should have... :-/

As strange as it sounds, I recommend trying another PSU. On the PSU that came with my 1200 I had all sorts of strange problems with the sound. All was fine when I plugged the 500 one in.

If you get sound from both outputs, but two channels are missing.... then the problem is definitely internal. It sucks, but you may have a faulty chipset. But a new 1200 is maybe 30 euro or so, so just buy a few as replacers.

I might say leaky caps ? btw, if you need a 1200 mobo, you can have mine (which was yours) for the postage. I don't really need it.

CountZero?

Well, if I "buy" it back. Can I buy it with sets of 3.1, 3.5 and 3.9 roms?

And a genuine japanese sticker which proves that it has travelled the world?? hehe

How much would it be? And would paypal do?

But lets not rush it. I'm going to test a few more things before I keel over and give up

you don't have to 'buy' it back. just pay for return shipping, and the roms I originally traded to you or you can send me the broken 1200mobo. I like broken mobos

I dunno ... probably around 20$. 35-40$ish if you want EMS (tracked, secure)

That's ok, take your time and give your board a good try

If I pay for shipping for it back to Oslo, I also want to pay for: The roms I received, and a new set if you have more roms :-)

And if we do this deal, you can have my A1200 board with dodgy sound.

Cool! Maybe I'll have to do some "nippon" stying on the case then...

Just want it fast Secure, insured and tracked is nice... But most important is fast I'm not as patient as you! You probably study "the way of the Samurai"... ;-)

Cool. Lets see what falls out of this. Want a AmiTech sound sampler btw?

It's collecting dust at this end, together with two sets of 3.0 ROMS for A1200. And a Blizzard 4030 with no CPU or FPU, A4000D daughter card... Several A4000 RAM chips, etc. I have bits and pieces, but no clear overview atm
