Does it persist past reboot?

Check different cables, speakers, headphones. A number of things can fail, not just the card itself.

I have rebooted many times, reinstalled dos / windows, tried many different cables.

The only output that works fine is the spdif out..

Have you tried midi (EMU chip) and digital audio?

Yeah, none of the features are audible via the standard line out.

However I I used a wire and connected it to the spdif/digital out on the sound card to another soundcard’s digital in and I can hear everything fine.

It’s really weird

Well maybe (if you did try the card on other machine, and other speakers/headphones on your current system) you card is buggy or it have some problem..
Try other audio card, if you have no matter what it is...

I don't know if electrolytics, or any kind of caps, can just kind of burn out like that. What were you connecting to it? It's a little odd if both RCA outs are low. I'd guess you're right about something going wrong on the board.

Do you have a detailed picture of the card for us?

Something I'd consider is giving it a golly good wash in warm soapy water, then obviously make sure it's 100% dry (compressed air for the components and then leave it somewhere ventilated for a few days). If it's not working anyway you have nothing to lose.

Did you try truing up your speakers to 11?

Hello all,

I have recently taken my old awe 64 gold out of the cupboard and started tinkering with it.
All was running fine for about 1 hour, then the audio volume level dropped dramatically.

Then I tested the output of the card via SPIDIF and works ok, but on the analog line out I need to crank it up to the last just to hear a faint signal!

Would any of you guys have any ideas?, could it be capacitors?

Thanks in advance,

Aaron

PS I checked all the mixer settings and all seems to be normal

You said it used to work then became lower after 1hr, but did BOTH channels drop at the same time? and to the same level?
If so, I doubt it could be caps, since both channels most likely do not share caps, and the odds of both failing at exactly the same time is quite remote.

I cannot recall, but in mixerset for the AEW64gold is there a GAIN setting on the output? Maybe that changed and you had it set initially to something beyond 1X.
