Toccata and noise...

[flaviosr]

Dear all,

I am trying to setup completely my "lovely" A4000T... :-)
My new wall is the Toccata!
It works but... it's noisy!
The left channel is ok while the right one is noisy! I can ear the music but there is noise on the background (and not only on the background!)... the noise is in phase with what happens on the screen... if I run a program you can ear noise and scratches accordingly to the opening of the windows and so on...
If I remember well I heard in the past about this problem and there should be some tricks to solve the problem...
Can somebody help?!?!? :-o

I have a Repulse audio card that worked great for years on my A2000 with a PP&S 2000/040 card.  Then when I updated the CPU to an 060 card suddenly I got crackly noise when recording.

I also tried this card in an A3000 and again got crackly noise only when recording (either via analogue or optical inputs).  

Very strange problem I can only guess might be noise on the Zorro bus....but I really don't know.  

Sorry, not very helpful, but it may offer some clue.  Have you tried the card in another Amiga?

mmm... my memory is not so good but I remember I tested it and it had the same problem... not so much anyway.
I think I have to make the following tests:
° changing slot (the A4000T has some slots... ;
° checking capacitors and connectors;
° I am going to change Amiga right now... too complicated!
I will let you know... but I remember I read somewhere about something to do to solve this problem with Toccatas... ARGH!!! My memory!!!

No. I am from Italy and my card is still here.
I could not make any tests.
Now I am very near to have a laboratory and I will get back again on the problem!
