So it looks like I have to add some capacitors to the PCI riser in my Fujitsu S300 to get a sound card to work. (Technically it works already - the driver initializes , there's just no output.) I did expect this, but was hoping it wouldn't be needed.
Problem is, I have no idea what values these caps should have & I'm not sure how to determine it. I haven't been able to find a picture of the riser with the caps populated - AFAIK it was never sold this way. (Makes me wonder why they bothered including the riser at all??)
Here's the riser in question:
Incidentally the part # on it is 736TR3230K100 Rev. 1.0, if it helps (it probably doesn't.) There are four through-hole caps and four SMD ones.
Question: do those surface mount caps absolutely need to be there? If they're all just bus filters, could it work "well enough" without them? I really suck at soldering those. 🙁
