Good day! First post here, even if I've been following this place for a while and found a wealth of information that saved my bacon.
I'm one of the lucky few with a marvellous LAPC-i and a pretty decent retro rig. (350mhz P-II with windows 98SE)
I tried to make sure the rig was stable before testing the few sound cards I still have, including the LAPC-i.
The card worked wonderfully for about a week before it would intermittently not output any sound. Sometimes a reboot would solve it, sometimes not. Windows detects the MPU-401 out and would show a Midi file playing if I start one.
At first I thought it would be a conflict with the present sounblaster card, (AWE64 gold, but having had a Roland SCC-1 installed beforehand, I knew not to have the SB's general midi at address 330).
I gave a shot with a SB16 value as well as a SBpro (in case manually having the IRQ and DMA set manually would help).
It sadly didn't work. However when the LAPC-i is the only sound card in the system, I can hear the mouse pointer move as static (coil wind?) in Win98 SE. Again, it's still detected, it just gradually stopped outputting sound it seems.
The jumpers are also at the default positions (irq-2, 330-331h)
Based on the topics here, caps might be a good start as well as, maybe, the opamp. Not sure what would cause this to happen or how sensitive the card is to possible PSU issues, as I had to replace it due to it not turning on reliably.
Any help is appreciated, I would really like to save this wonderful piece of technology!
Thanks 😀
