It’s a CT2230 card pulled from storage but never had any issues.
Settings are 220, 1, 5 and when starting Doom, Doom2 and Heretic the music works and sound FX too. But the latter will only work for like 5-10 seconds. Then there are no sound effects. Music will still play though.
After restarting the game there is a notice in the load screen stating: SB isn’t responding at p=0x220, i=5, d=1.
Rebooting makes the sound effects work again, but yeah - only for a few seconds.
Is this card dying?

Possible.
But the problem may also be as simple as bad contact on the jumpers - Re: Drivers/Questions about ESS488

FM synth is fixed at 0x388 = no problem.
DSP address is jumper-selectable = bad contact causes intermittent errors.

In 2003, I voted in favour of joining the European Union. However, due to recent developments - especially the restrictions on cash usage - I'm hereby withdrawing my support. DOWN WITH THE EU!

I took a closer look at the card and found some corrosion. Seems that cap is leaking, although it’s not bulged.
The corrosion looks more like rust but I soaked the area with deoxid and will clean it with isopropanol and a toothbrush.
