Title: Picasso IV sound troubles.....Any ideas?
Post by: Sandman on December 03, 2008, 04:26:58 PM

Hi all,

PC speakers hooked up through native A4000d audio outs sound fine but when hooked to the PIV, the volume is reduced and sound is diminished.

I have tried reseating the audio hook-up cable flipping it around and even tried replacing it to no avail. Have tried moving jumper for audio groundin on the card from internal to external and that didn't help either.  :-(

I would just use the native audio ports but I like the switcher software requester with the PIV.

Thanks,
Tim

You need to connect some spare rca plugs to the a4000 sound output. Otherwise the audio signals on the VideoSlot show exactly this behaviour.

Actually, I already tried this as I just plugged in some spare rca patch cables and it didn't make any difference so I just used some plugs... no difference.

I read somewhere else that there was a mod that needed to be done to this board to fix this problem.. something about removing a capacitor or something, I'd like to find out some more info on this.

Thanks,
Tim

For older boards a capacitor needs to be removed and a resistor to be replaced against a 0Ohm bridge.

Have to look up which ones.

I have the same issue with mine, would like to know how to identify whether my board needs MataTabs' fix.

Arrghhh!  I just decided to run my audio and cd audio from the motherboard...... Had to tear everything apart though to get to my PIV to remove the cd audio cable and then hook it to the mb.  Then after I got everything back together the thing wouldn't boot - I thought that I had wrecked something! :madashell:

Turn out to be that I just jostled some of the mb ram chips and that was the whole problem... after I had removed and then replaced every component one-by-one.  Nothing better to do all day on a Saturday anyways! :lol:

Everything back and running sweet now.... Funny that my first thoughts everytime is that I hope that I didn't fry my WarpEngine or PIV!  :-P

I'd have any easier time panning for gold than finding some of this Amiga hardware.
