Terrible sound coming out of my Auzentech X-Fi Forte

post #1 of 3
Thread Starter 
Since today, I'm having an issue I can't explain with my sound card.

It bears mentioning that I installed a brand new Dell U2312HM monitor on my computer today. I also have an LG M2380D TV/monitor connected to the video card, but that's not new.
The sound I'm talking about can be heard in this video: http://www.youtube.com/watch?v=-m9p7KQFzTA
What's interesting to me is that the monitor shown in the video looks to me like a Dell U2311H. I know that's not the same as my U2312HM, but the coincidence is interesting. Just thought I'd point it out in case it's relevant.

http://www.youtube.com/watch?v=D5EEAUe8wfk also portrays the same issue, although in this guy's case it appears to be constant, whereas it's very random for me (and never lasts very long); there's no pattern I can see. It's only started happening tonight, and all I've been doing tonight is sit idle at the desktop, or watch a movie, or browse the Internet, or a combination of #2 and #3. Setting the volume to zero does nothing.

I also found http://community.auzentech.com/node/535 which seems to talk about the same problem.

My U2312HM is connected over DVI; my LG is also connected via DVI but there's a DVI-to-HDMI converter because the monitor does not have a DVI input.

Based on that last link, I checked if there had been an update to the sound card's drivers, and there was (Sep 2011), so I installed that. I also uninstalled AMD Catalyst and reinstalled it, making sure to do a custom install and not to install the digital audio driver. Still I got the noise for a few seconds minutes before I started this post. It also happened earlier while I was rebooting, shortly after POST ended but before Windows started booting.

I messed around in the back of my computer, disconnecting both the speakers and the mic, leaving the headphones, but still got the problem. Owners of the Forte will know that connections on the back are done through what looks like a serial port splitting into a small bundle of cables with 3.5mm jacks. I removed that dongle as well just in case it was messing with something, but no difference. At some point I was able to do and undo those connections while the noise was "playing" and it was not affected.

If it's a coincidence that this started on the same day I installed my U2312HM, that's alright, but if it's related, I really, really wonder how that works (and as much as I like my Forte, between it and the U2312HM, I'll keep the monitor).

Anyway, reading comments on the YouTube videos, it appears that contacting Auzentech may result in a solution, but before I go and do that, I wanted to consult you guys. So if you have any input, I'll be very eager to hear about it.
Thanks!

Some caps need replacing. The Forte is a great card but is notorious for annoying problems, one of which is caps that can have problems in the first year from heat. My Forte lasted 9 months. When it started making the machine gun noise at full volume I had enough of the problems and gave it away.

Ugh, not cool. At least I'm glad you're saying my problem and the new U2312HM are unrelated.
I opened a support ticket with Auzentech earlier, so maybe they'll offer a solution. Otherwise, can I replace those caps myself, maybe with higher quality ones (e.g. Rubycon/Panasonic/NCC rated at 105C) ? I don't own a soldering iron but I figure it can't be too hard if I get one? Anyway, my Forte does sit right above my 5870, and while that's not too hot a card, I'm guessing the heat could have hurt the caps... jeez.
