Well, I am not sure if it will cheer you up, but I also pick a lot on noise on my Dell.<br>I use the headhone socket on the built-in soundcard, as I assume you do.<br>The noise is not noticeable on my old Sennheiser headphones (can't remember model name), but i get a really nasty sharp buzz when I plug the card output into my mixing desk.
<br><br>
Funnily enough, the noise greatly depends on system activity.<br><br>I am not practical enough on electronics to help you diagnose the problem. Just a few thoughts :<br>- The word 'impendance' has been used before and indeed, I would think this makes a big difference,
<br>- Re : grounding issues: the buzz stops here when the Dell is only powered by its battery. Have you tried to unplug yours ?<br><br>These PCs do have a grounding issue; I have rehearsed with a live band lately, and even my external Firebox soundcard produced the same annoying buzz if the Dell was sector-powered. So I left it on battery during the gigs, and reloaded it during the breaks ...

Just got a new pair of headphones, Sennheiser 280 Pro's, to be used<br>while working on my computer. Unfortunately, I'm picking up what I<br>think is system noise, that cheaper 'phones don't detect. My system<br>is debian on a dell box. Amarok is my favorite player, but it's also
<br>the noisiest. The noise is a low level hiss/buzz and can be detected<br>even when Amarok is totally muted. The noise intensifies when I move<br>the mouse around and over links, hot-spots, menus etc. I posted to<br>Amarok, and Xine, but they suggested the problem was in my system. I
<br>turned off unused channels in alsamixer, but that didn't help. Same<br>noise for sessions in kde or icewm. The problem is not the headphones<br>themselves, as there is no noise when used in OSX and iTunes.<br><br>I'm willing to try a few things, if anyone has any suggestions, but I
<br>don't want to mess around with major surgery on my system. If there<br>is no obvious/likely software solution, I want to exchange the<br>headphones. In that case, can anyone suggest headphones that might<br>work better. Obviously, I'll lose some of the quality that the 280's
<br>provide, but that would be better than the noise. Is there something<br>in the specs of 'phones that I should be looking for? Also, frankly I<br>don't like the closed circum-aural 280's as much as I thought I<br>would. They're a bit hot and tight. Is there a lighter open-ear
<br>headphone that still might be reasonable quality that might work<br>better for me?<br><br>Hope my question isn't too off-topic. I've subscribed on and off to<br>the list for over a year and have been greatly helped in the past.
