Hi all,
Wondering if anyone can offer any suggestions for a problem I'm having with a newly installed 2nd hand Prelude A1200.
I've installed the Prelude onto the Clockport of an expanded A1200 (BlizzPPC 240/060, BVision, 256Mb RAM, OS3.9) and installed the s/w from
http://prelude.act-net.com/softindexe.html.
The machine boots up fine and I can even use the mixer to control the volume of native Amiga sound and direct CD audio connected onto the AUX1 and AUX2 connectors respectively.
However the Prlcheck program returs the following output:
PrlCheck V3.9
This program will perform some lowlevel checks on the Prelude soundcard.
ATTENTION! Any playback or record currently in progress will be interrupted!
Attempting to find the board.
Prelude 1200 soundcard detected.
Address: 0xD80000
Revision: #1
Resetting card.
Autocalibration cycle complete.
Checking register status.
Register 0 contains 0x01 instead of 0x40
The Prlcheck result after resetting the card using PreludeReset is the same.
What could be wrong?
The other question I have is that the board came with a little patch - a little yellow wire soldered directly onto the 5th pin (I think) on the leftmost side of the left AM7202A-35JC 9834EBA chip to a track directly underneath on the board.
This little wire fell off before I installed the board so not sure if this is the culprit.
I soldered a replacement back on. The only slight issue is that the 4th pin (from bottom) also had a bit of solder on it but as the 5th pin had more solder on it, I assumed that's where it was originally. Also I made an educated guesstimate as to which point to solder it back onto underneath the board from the flux stain on the board.

Can anyone shed any light on this? Does it sound like a patch to fix bug or a patch to repair a broken track on the board? None of the original tracks seem to be routed to where the patch is installed. I'm wondering if I've got it in the right place.
The Prlcheck program has been returning the same errors with and without my replacement patch. And the board behaves the same way with and without this patch. The play a test sound in AHI plays silence through the Prelude. Native Paula audio is fine.
Any help much appreciated.
