Impedance for 1998 Sound Card Recap

This is not a question of '22 years ago' but does instead depend on the 
capacitors purpose.

Take a look at the originals, find their data sheet and look out for 
their properties. And if the originals are not available any more, look 
for replacements.

Please tell me: Which ESR value was common in electrolytic caps (100u, 
220u and 470u) two decades ago?

Actually the card works fine when PC is freshly booted.

The problem arises after awaking from Suspend to RAM, then it's dead 
until next reboot.

And that's a new problem which wasn't existent a while ago.

Therefore, I guessed the caps.

This obviously has nothing to do with the capacitors. Its a software 
problem.

It's an Arch Linux :(

Now I managed to reset it after wakeup.

1

sudo sh -c "echo 1 > /sys/bus/pci/devices/0000:05:01.0/remove"

2

sudo sh -c "echo 1 > /sys/bus/pci/rescan"

Then it works again.

But really?!?

Really!
