Windows 7 Crackling Noise

Hello.
I recently upgraded my Bootcamp partition from Windows XP to Windows 7 Professional on my 2008 24-inch iMac OS X 10.5.8. Before I upgraded, I used the Realtek sound software provided when I installed Windows XP. When I upgraded, I had very little sound. Installed the newest Windows Vista & 7 Realtek software, version R2.70, and it worked fine — except for one, incredibly annoying thing. Every couple seconds, I hear a crackling noise. I've tried re-installing the Realtek software and using different headphones, but no dice.
Has anyone else had this problem? Is there any known way of fixing this? If not, what would you recommend I do?

Static crackling noise, Right speaker when audio is being played

I recently purchased this Satellite C50D-A Windows 8 Laptop. I have had it for less than 3 months. Recently the right speaker has started acting up with some sort of high pitched static crackling noise whenever audio is played regardless of it being in a web browser or any other media. Even computer sounds are distorted from this. I typically use this computer for school and play music to study. How the hell can I fix this so I can actually listen to audio without this rather irritating issue?

I tried that and it didnt seem to do much of anything.
I played part of a song on spotify and recorded it to perhaps give you an example of what it sounds like?
I covered the left speaker so most of what you hear is the right speaker alone. The distortion is pretty clear when audio comes out of that speaker.

Crackling noise after OS X update

hi,
I have external speakers plugged into my MBP, and after the update, after a sound had been played, like a system alert or something, after a few seconds there was a crackling noise. It is as though the soundcard is turning off to save power, as it also happens when i am running on battery mode (i know this because i ran from battery power while i was running 10.4.9).
Does anybody else have the same problem or know what the problem may be?
Thanks

Does anybody else have the same problem or know what the problem may be?
I do have the same problem. It's good to know that I'm not alone. My MBP's sound card was defective from origin and it was replaced under the warranty. Ever-since I'm a bit paranoiac that something similar could happen, you know, that the sound card getting damaged could be only the result of another internal device damaging it.
Anyway, I hear all those noises and I don't really like them but I could live with them if necessary till an additional update is released fixing this bug.
I have to say though, that I have always believed that the audio doesn't really increase properly. We all know that the sound, from none to full, increments 16 times... Well, according to me, when you are turning the audio up, it goes up very poorly till it reaches the 10 or 11 little square, then it really cranks up. Put it in a chart, the increment doesn't draw a straight diagonal line, but a curve, a parabolic line. And also, the sounds performs very differently in Windows. Much better I believe.
Is that not true?

Severe sound crackling noise with SB X-Fi ExtremGamer and 680i m

My computer suddenly (~3 weeks+ after my new build) started making extremely loud crackling noises anytime I have sound on. I remember hearing some crackling noise before on one occasion, but not nearly at this level and it seemed to "magically" disappeared so I forgot about it.
I swapped the speakers to another computer and verified that they are not the source. Unfortunately, I do not have another sound card to swap and check. I updated all of my mobo and sound card drivers, and tried my sound card on both PCI slots on the 680i, all to no avail. EDIT:Happens even with no applications and speakers on, just having Windows running has a slight crackle.No overclocking on my system.
On-board sound is disabled on BIOS.
It still makes ths sound with speaker wires touching absolutely nothing (and also stretched out as to not be wound up).
No microphone on my system.
() Is anyone aware of any issues similar to this?
(2) Should I just RMA my sound card?

Please help - horrid crackling noise ruins mp3s - more info

I have just realised that infact all the music that I imported from my friend's computer, that played fine in the old i-tunes, is covered in this horrible crackling noise in i-tunes 7.
My friend's computer is a windows pc and i imported the files via our ethernet. The crackling sounds seems to happen when the pitch of the music gets too high.
If anyone can tell me what i can do about this I would be very very grateful.

Check your import settings. If the bit rate is set too low, the music will sound like crap. If it is less than 64kbps, reimport it at a higher bit rate (I suggest 128 if you have enough space for it). Remember to reimport the original files (the non-crappy sounding version) or else it won't improve.
Cheers,

Crackling noise while record

I just got a new X-Fi sound card and when I try to record with it I get a crackling noise while recording BUT plays great, when its recording I get the nose and as soon I stop the recording the crackling noise stops, I did have a sound blaster li've 5. and I never had this prob with it's? dose anyone have a clue to what would cause this?
Now I did just do a major computer up grade:
AMD 64 3500 2.2 Ghz
ATI 52MB video
Gig of ram
300 Gig HD
ECS K8T890-A Mother board
Soundblaster X-FI Xtreme

I just found out, that the crackles only occur when I record something using the windows audio driver while/after an application is/was opened that uses the ASIO driver. The crackles do not occur if I record something inside the ASIO application.
I hope you understand what I mean.

Music Playing Twice as Fast and a Crackling Noise

When I first play music on itunes, there weren't any problems at all. Once my CPU usage goes up (like when i play a game) the music plays twice as fast and theres a crackling every second (1 second music then 1 second crackling noise ). Once I lower my cpu usage, the music returns back to normal.
I didnt have this problem with the previous version of itunes though.
dell 8400 Windows 2000 Media Center Edition

I am having precisely the same problem and also did not experience this with the last version of iTunes. As opposed to Jagged_Link, however, I am always getting this problem. I have a very fast dual core computer Athlon 64 x2 4400 with 4 GBs of Ram so I don't think that a performace issue is the source of this problem, but I do have many other applications running at the same time (azureus, firefox, beyondTV). This was never an issue with the old version and I think that the problem might have to do with the gapless playback analytics (a problem with the process, perhaps). I will try eliminating all apps other than iTunes to see if there is a change.
By the way, a repair of iTunes, using the original installation file, did not change my situation. I only use MP3s (no AAC) and it be helpful if the other posters can provide this info as well, so that the problem can be identified better.
I hope we can find the problem and get it fixed!

ALSA USB Headset Crackling Noise

Hi, I'm having some problems with my USB Headset that I'm using for my sounds, which when I play anything with sounds in it, it gives me crackling noises. I'm using ALSA and my headset is the Razer Megalodon, however, the headset works perfectly fine on Windows, just not on linux. I tried all of the usb ports on my computer and all of the solutions in the wiki for ALSA, such as using and installing asoundconf from AUR and adding "options snd-usb-audio nrpacks=1" to my /etc/modprobe.d/modprobe.conf with no luck.
I even tried using PulseAudio, hoping that I'd get some better results, but sadly, I still get crackling noises. I even tried adding "tsched=0" in my /etc/pulse/default.pa with no luck.
Here's my lsmod: https://gist.github.com/anonymous/5333572 or if you prefer: http://ix.io/54h
I'd really appreciate it if someone could help me fix this problem, thanks.

This blog seems to suggest:

Doesn't help me either, I tried adding that to /etc/modprobe.d/modprobe.conf and still doesn't work. I tried changing from snd-hda-intel to snd-usb-audio and that doesn't work either. I even tried typing in: "modprobe snd-hda-intel power_save=0 power_save_controller=N" and that didn't work. Also tried changing the snd-hda-intel of the modprobe command to snd-usb-audio, still doesn't work.
Anyone else have any ideas? This crackling noise is really obnoxious and makes watching things unbearable.
EDIT: I didn't fix the problem, but what I did was remove ~/.asoundrc and ~/.asoundrc.asoundconf. I edited /etc/modprobe.d/modprobe.conf and removed everything and added "blacklist snd_hda_intel" so I didn't have to deal with any onboard soundcards. I removed asoundconf from my computer and removed pulseaudio (just in case). All I have installed that's related to sound is: alsa-lib, alsa-plugins, alsa-utils, and lib32-alsa-lib. I'm going to be working with a completely clean configuration of ALSA, so if anyone has any suggestions please go ahead and let me test it out. Obviously if anything relates to snd-hda-intel, it won't work on mine because I blacklisted it, thanks. Also, what was funny enough was that when I completely uninstalled everything and had a clean configuration, my sound was working completely fine with no crackles for the first time! But when I restarted my computer, it went back to crackling for some reason.

So I have a 1.5 year old Macbook Pro (Early 2011) and since last week, it has been making a crackling noise that has escalated to a grinding noise. I went to Genius - they told me my HD was fine, but they could do nothing about the noise. I'm super upset

I have a Macbook Pro that I bought new in August of 2011. It's been wonderful up until now. Last week, I was watching a lot of Netflix for a day, but then it began making a tiny crackling noise when I started my computer. It wasn't really bothersome, but then it's escalated into a grinding noise. A loud grinding noise. I haven't been watching Netflix and barely use any of my applications. My RPMs vary when I'm idle and can go up to 5000. Sometimes, it falls to as low as 1600.
I went to the Genius Bar today and the technician did two diagnostics to test the HD and the parts as a whole. Everything was fine. I was like, ***. Anyways, I asked if there could be anything done for the fans because I was willing to pay (I'm out of warranty). But he said they couldn't DO ANYTHING. That I would have to deal with the annoying noise. I called up Apple and told them what happened and she said that there was nothing else that could be done.
I am so ****** because I did pay good money for this product and I expect to have the option to repair, ESPECIALLY since I'm willing to pay for the repair. Can anyone tell me what to do? Did anyone ever have this problem?

I would guess the fan is the cause of the noise. Suggest you take a look at it.
This site has a wealth of information about getting inside a Macbook or Macbook Pro.

Crackling noise while viewing Sky TV in bedroom using RF cable

Hi, We currently have a sky box in the livingroom. As we seem to have a really bad signal in our bedroom we cannot use freeview in there. We also cannot get Sky multiroom as we live in a flat. We now stream Sky from the livingroom to the bedroom TV using a RF cable from Sky box to output in livingroom and RF cable from output in bedroom into that TV. This generally works well and the picture is ok however we get a loud crackling noise every so often that we cant seem to stop, lately this noise has gotten more frequent and louder. Can anyone advise why this is happening and how to fix it? Thanks.

Hopefully that will make it easier to fix!
Try changing the RF Output Channel your Sky box is using. By default it's set to channel 68. Try a channel at the other end of the range - say 25.
To do this. key Services,0,0,1,Select on your remote to get to the Installer Menu. Don't pause between key presses, don't wait for the screen to change and don't forget the Select at the end! At the Installer Menu, you'll see the RF Output tab where you'll find the Output Channel setting. Change to 25 and press Green to save the change.
Onceyou've done this, you'll need to re-scan for channels on your bedroom tv, using its setup menu.
You may need to try several RF Output Channels before you find one that works reliably.

MacBook Pro 13" makes crackling noise

My MB Pro that I got this year just began making a crackling noise last night when I touch the plastic port on the hinges and when I adjust the screen back and forth it makes that noise aswell. I just wanted to know do I need to be worried that it's a major problem or can I look past it? Any damage on my MB Pro in the long run due to the plastic part of the hinge?
Thank you.

Take advantage of your warranty and have Apple check it.
Ciao.

Crackle noise with plug-ins at the beginning of a region

I've experienced problems with some TC plug-ins and logic. Mostly with the Brickwall Limiter and TC Helicon Voice Modeler.
When I insert one of those plug-ins in a track, the crackle noise occures when the SPL is almost before the start of the region. So, when this region starts at measure 5 I hear this crackle noise somewhere in measure 4 (also in the bounce). And here is the most stupid workaround!! I have to place a dummy region before measure one of the song. Now, I can bounce the song (from measure -1). I still have this crackle at the beginning of my bounce (before the music starts) but now I can cut it because its at the beginning of the song. The crackle doesn't occure a second time, only when the first region on this track is passed.
I had some consultation with TC and they asked me to send them a file although they didn't know about this phenomenon.
They also recommended to experiment with "automatic delay compensation" and buffer size but it didn't help. Any ideas??

Samsung TV-HDMI Cable Crackling noise during video play

I have a Samsung Plasma 50inch. Just connected the HDMI cable and audio/video works great except when they're working at the same time. If I watch any movies/videos, there is a crackling noise coming from the speakers. (If I mute the TV, the crackling noise disappears.) Any suggestions on what I should do? New cable? TV issue? I'm currently using a Belkin HDMI cable.
Thanks!

It could be a problem with the cable box. Connect your cable directly to the TV and see if you still have this problem, if you do call Samsung, if it goes away call your cable company.

Nokia 5610 with crackle noise when use headphone

but when i play the same song by mp3player with the same headphone i can find the crackle sound

Go to Solution.

ders a few reasons y that may occur, there could be something wrong with the 3.5mm av in port, it could be dirty or damaged, or it could be a software thing where the music isn't being sent through as complete data through the connection. der r other reasons, either way, i would advise you to see a nokia care centre, especially if your warranty hasn't yet reached its void.
