Has anyone experienced this before? This happened to me even under CentOS 4.x. But basically what happens is that when I play MP3s, whatever the right speaker crackles at higher volume. And it's always that speaker and only that speaker. If I turn the balance to the other speaker I have no problems. So it feels like it might be a mixer issue. I use Alsa, of course, as that's what the default is. Is this a known issue or does someone know how to fix it?

Do you experience this with any other file formats? Different media player?
Personally I would say your right speaker is bad. But maybe I am misunderstanding.

Yeah, it happens with other players. Although to be empirical I suppose when I get home I should see which players.

No. That's not it. I've attached 3 pairs of speakers to it and it's always the same thing. Plus you can hear like hard drive noise coming through. i.e. When the hard drive is churning the static is in rhythm with it. So I know it's something related to either the sound card or how the OS is dealing with the sound card. I've done some Googling and it appears to be pretty common, but I can't find a solution that works for me. Unless maybe I need to put in a standalone sound card.

plug some small headphones into the line out jack of the sound card (large phones require too much juice), and see if you hear the crackling over these under the same settings. if you DONT, its not the system or the hardware, its your speakers. if you DO, you can continue to look into sound card issues.

I'll try that, but why would 3 pairs of new speakers not be able to function on the exact same side? I'm not sure I understand the technical reason why all 3 speaker sets (different brands) would be malfunctioning on the same side.

It could be as simple as a bad/dirty jack on the output. That would explain why all the speakers are noisy on the same side.

Yeah. Plugged in headphones and the same thing happened. No way it's software related? Weird. I guess maybe I'll try putting a sound card into it.

Nevermind. Figured it out. I got the tip from a Linspire messsage board, of all places.
I commented out the following in /etc/modprobe.conf
#alias snd-card-0 snd-intel8x0 #options snd-card-0 index=0 #options snd-intel8x0 index=0 #remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; # /sbin/modprobe -r --ignore-remove snd-intel8x0
And replaced it with...
# ALSA portion alias char-major-116 snd alias snd-card-0 snd-intel8x0 # module options should go here # OSS/Free portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss
Rebooted and now the sound is clear. No more crackling. No more hissing. Very weird. After 2 years of ignoring this problem and then hoping it went away with CentOS 5, this fixed it. Thank you, Linspire users. :)
