Soundcard makes constant ticking or clicking sound

I can hear a constant ticking sound in the background at roughly a frequency of 2 per second mainly when nothing it playing. I have a Creative SoundBlaster Audigy 2 card and 5.1 speakers connected -- and the latest driver I can find for it for my OS (Win XP SP3).

It didn't always do this, but I don't recall exactly when it started (for example if it was after I installed some hardware or software). Anyone have ideas on what could be causing it or how to fix it?

OK, I've apparently found the culprit and fixed the problem myself -- although the solution doesn't make a lot of sense to me.

While checking to see if it was being cause by one of the many devices clustered around the system and speakers, I happened to notice that if I moved my Internet gateway/wireless-router nearer to my NAS the sound grew louder -- not that either of them have anything obvious to do with sound generation. Anyway, I got it to go away completely by rearranging things so that now the gateway is as far as possible from the NAS enclosure (which is about 6 feet vs the roughly 8 inches they were apart previously).

Wireless interference. While your router has nothing to do with sound, it surely emits radio waves (a.k.a. WiFi signal), and your soundcard acts as an antenna, picking it up. – Piskvor left the building – 2016-01-06T13:38:52.687

@Piskvor: The mystery is why would moving my gateway/wireless-router further away from my NAS cause more WiFi signal interference? Neither of them are directly connected to my computer, and the latter doesn't use WiFi itself. – martineau – 2016-01-06T15:40:18.143

Take a look at the wiring. Those sound cards are not exactly new. I had a SB128 (and it still works) and I remember I also had that ticking sound sometimes. I managed to make it go away was by replacing all the wiring coming from the card to the speakers and lubricating the connections with WD40.

Good luck.

Yes, that was my first thought from other things I've read about the possible causes, however it turned-out to be a device --somehow -- in this case. Thanks for your thoughts. – martineau – 2012-08-05T19:03:56.093
