Anyway, curious thing, when I first installed the card, I didn't have internet so Windows didn't installed it automatically, then I searched a bit and found out that Creative X-Fi Xtreme Audio it's very similar, so I downloaded it's drivers and force windows to install them. Worked perfectly, except it didn't show the jacks information. Later on windows update offered a driver update, and I'm using the "normal" driver now.

 

I'll mess with it after I mod my card, but I'm not sure how to start.

 

What opamps and capacitors should I use? I heard at another thread that film capacitors are much better, but I researched for types of capacitors and there are so many!

I'm a PC hardware distributor and have access to dead motherboards which have many kinds of capacitors. =D

 

What should I look for? Big ass values? Solid ones?

 

The big green capacitors I see replaced at the pics are all the front green jack uses?

 

Audio grade caps are your best bet. I recommend Nichicon's muse series or if you have the money Rubycon Blackgates. I would stay away from large capasitance and go for quality.

I used 220uF Nichicon Muse caps for the opamp buffers and decoupling caps.

Sorry for the delay, I was moving and I just now got internet back. smily_headphones1.gif

i'm using opamp 4560 for front & rear channel,, forgot it's JRC or LM.. but it's a cheap n nice performer opamps i think.. the center/sub opamp haven't changed,,but i have a spare AD8066...

 

for caps u can see yourself.. it's pana fc , pana hfz (the dark big blue one) , elna silmic II , oscon.. the capasitance is the same with stock caps,, only the voltage is bigger.. 

 

i'm thinking to change the panasonic hfz caps,,what caps do you recomend ? the candidate are elna silmic II , elna cerafine (i dont know this caps characteristic)

After a lot of research and testing I have fixed the dreaded creative crackling sound problem.

 

The Audigy 2 suffers badly with this as well.

 

Here is the 100% fix

The caps are too small on the power regulators causing ripple instability.

 

In the case of this board look at bottom rH corner and replace caps

post #20 of 20

Replace the small caps bottom RH corner with 100uf 50v electrolytic. Problem fixed. Be careful to insert noting polarity ie the negative stripe on the cap must be in same whole. Dont think rest of board is where problem is. Only around the power regulator devices.

 

This effects audigy 2 as well
