Emu 1212m just recieved-I'm having problems getting loud enough sound out of it. I've installed patchmix and emu software/drivers and left them on default settings as well as foobar2000. My problem is that I've been playing about with most of patchmix's options, but the sound isn't loud enough even at max volume on my Rs-1s. I.e. Usually my ra-1 is at 2 o clock from my cdp, here its flat out and still at a much quieter volume than that. Please someone help me out here and get it back to perfect working order. I think the problem is that I've maybe soldered a tiny cap (16v 10uF) in the wrong place, as 3 fell off in transit from Zemo to me. Would this make the op-amps power drop drastically or become unstable? I think it would so please check the following pics of the boards now, and check whether the caps are in the right places, and suggest where the final cap may go on Zemos pic. Thanks guys, here are the pics of the boards:

Here's my pic again but with Zemos circled suggestions of where the tiny cap may go:

Did you have to make 2 posts about this? Why not just ask Zemo? You'd think parts falling off your soundcard would not be good.

Yes, I need some people to answer and the other thread had a less attention grabbing title. It's really frustrating when the dam things sitting here and won't work right. Zemo I've already asked about this, thats who circled suggestions for tiny cap places on the last board pic, if you read it you'd know that. To avoid trying every one of the 4 places he suggested it might go, and see which one makes it work right, I'd like people to check the boards against their own to see if all the caps are in the right place. Also tell me which one of the four circled places the tiny cap goes in.
The caps fell off the sound card in transit, its Zemos fault for not padding out the inside only the outside of the emu box, but I forgive him we all make mistakes.

You said three fell out but are trying to figure out where one goes which could be any of the 4 red circles? What happened with the other two capacitors?

I don't know what these new values of caps are but I could take a pic of the original board if that would help you. You'd get the original values and positions. But really though Zemo should be the one to help you since he's modded these before. I assume he should know exactly the values which goes where. It shouldn't be a guess or a suggestion. If you didn't know how to solder, you would've had to return it to him anyway because the product shouldn't arrive broken.

Another thing, I think some of those other caps are hanging there and not in the holes which is not mechanically strong. It's because some blackgates's pins are too large for the holes. So be sure to be careful in the packing.

I soldered the other two back on, one was so big it was obvious where it went, opposite the only cap on the board the same size as it. The other only one leg was hanging on by a thread so that wasn't a problem. The only cap left to re-solder is a 16v 10uF as I stated earlier.
I don't want to return the emu to Zemo because he doesn't know for sure where it goes, as I said he just suggested four possible locations. Pics of the two boards (one pic a side) would be great Ian. If you could do that, I'd be really happy as I could check where all the caps are supposed to go and correct the difference/s on my emu boards. Please do a better job than I did taking pictures though!
BTW I do know how to solder as I did electronics at school. You know am radios, cmoy type amps, etc. Not much I know but I can do it. The reason I didn't mod an emu myself is that I didn't know my dad had a soldering iron in the garage. I also wasn't confident that I wouldn't muck the emu up if I messed about with it. Finally I didn't realise the board was so easy to solder on. No caps near anything that can melt easily, and the tracks are quite far apart from each other. I wish after this pain in the neck I'd bought the emu and modded it myself. Still you live and learn, next time a new FOTM sound card comes out maybe I'll be second to mod it after someone like Iron_Dreamer does the initial fault finding and testing.

Here's the pic of the board

Bottom two red circles are 16V 10uF.

The top red circle is also 16V 10uF.

The one slightly below this top one and to it's right HAS NO CAP so it shouldn't be a red circle at all.

Thanks I'll take the emu daughter board out later and see which one out of the three positions looks most likely.
