Ubuntu Multimedia :: Crackling Sound In 11.04, Already Searched For Solutions?
May 15, 2011
I've been through what I could find in searches here, but nothing fixed the problem so far.Here's the situation: I am using Ubuntu Natty 11.04, dual booting. So I know the sound is fine on the XP system, and also works crisp and clear on my Vista laptop sitting next to me. I've tried the sound through Banshee, Amarok and Exaile all with the same crackling as if the file was ripped off a bad CD. I'll repeat that I've tested the speakers, and also the jack port (being that there are two on my PC) so I am fairly certain it is an issue with Ubuntu. Here is the ALSA information report: http://www.alsa-project.org/db/?f=ad...8b8d1ee19905a5
It's not a problem with PCM- the crackling will go away if the level on PCM is like 30~ but then the sound is very quiet even with Master and speaker volume at 100, at which point you can still make out the crackling.

I recently upgraded to Ubuntu 10.04 from 9.10 and there's now a strange high-pitched crackling distortion sound whenever I play any kind of sound with any program, which seems to stop and start at random. My sound card is an SiS SI7012, and the sound was working perfectly before I upgraded.I'm not sure whether this is a problem with Pulseaudio or ALSA or what. I tried removing all of the Pulseaudio packages, but that didn't help, and I also tried doing 'remove completely' on all of the Pulseaudio and ALSA packages and then reinstalling, but that didn't work either

I've been trying to configure my revo R3700 over the last day and I'm finally there. HDMI sound is working apart from the fact that all sound is crackling. Sound is working through analogue without issue its just HDMI that is distorted
I initially did the command
aplay -Dplughw:1,7 /usr/share/sounds/alsa/Front_Center.wav
Which produced no crackling or distortion. I then tried a mp3 which was distorted and crackling, upon trying the same command as above later on, this too started to be distorted
Searched through the forum and theres a few people that have had this issue and have resolved it simply by edited alsamixer however this isn't working.

It seems like it's mostly an issue with playing games. When I play certain 3D games, the audio may work for a little while, but will start getting scratching or full of static. Some times it's a lot, and other times it's just a little bit. Most times, the sound in the game will stop working after a short moment of static/scratchy sound. Then I am left with complete silence.I've seen on other posts that PCM volume may be turned up all the way. I wasn't sure what PCM was, but in the volume controls, I saw that you could adjust each individual application's volume. I assumed that this was PCM, as the game's volume was all the way up.I turned it down some, and I still got some static in the sound, and the sound still disappeared completely after a short time.

I have upgraded (twice) to 8.1 and I get constant crackling sound - interestingly only from my left speaker. It starts already after the GRUB boot, and when logged in it just cracks all the time.
- in Wheezy there is no this kind of problem
- I have installed Jessie (crackling), fresh install back to Wheezy (no problem), fresh install again Jessie (problem), back to Wheezy (no problem), and now Jessie (again problem).
- the volume slide is jumping like crazy together with crackling. There is no chance to manually change it.
I have managed (by some unknown chance) to set profile to off, and now it disappeared. However, it comes back ON when rebooted.

I recently installed Ubuntu Natty on my Toshiba Satellite A210-139. Everything works fine except the microphone. I can hear a crackling sound also when I record using Sound Recorder, but it's not too bad. The big issue is with skype, where, besides an annoying, loud white noise, the receiver hears me quite intermittently. I tried many things. Firstly, I played around with Alsamixer and Pulseaudio with every possible combination. Didn't work. I also tried what seemed to solve the problem to many users: replacing
Code:
load-module module-udev-detect
with
Code:
load-module module-udev-detect tsched=0
in /etc/pulse/default.pa

I have installed Skype beta 2.1 on my ubuntu 9.04, everything works except the mic. All I get is noise (SSSHHHHH) when i try to use it. moreover Looking in volume control, no matter what volume I have the mic set to initially, as soon as I initiate a call the mic volume goes all the way to zero (then initiating that crackling staticky bug) and turning it back up doesn't work as the volume slider just slides back down. and also one of the mic channels (left or right, I can't remember) comes to zero and slowly the other follows it.

I use a Creative Fata1ity USB Headset for playing games. I use a VOIP Client called Mangler for ventrilo. I play WoW via WINE.
I am not sure what is causing it, but the sound quality will be amazing and then randomly go to this crackling, static, ping, underwater sound for people in Mangler and for the WoW sound.
What I do is go system > preferences > sound and then turn the sound to off and then back to my setting and it is fixed. It will then come back randomly. It could be 5 minutes or an hour.
Anyone have any clue what this could be or how to narrow it down. Makes raiding kind of hard when I have to fix my sound randomly while healing a boss fight.
It did this on 10.04 and then on 10.10

I recently upgraded from 9.04 to 9.10 (9.04 support just ran out). Ideally, I'd upgrade further to 10.04 or 10.10, but I am somewhat bandwidth limited, and so the additional 1.5GB upgrade to 10.04 is a last resort. After upgrading, I picked up a nice crackling sound. It seems to be tied to activity. Typing up this post resulted in a few crackling sounds a minute, but scrolling up or down, resizing windows, or doing anything more intensive (such as listening to music), and the frequency picks up.
lspci lists two audio devices: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)01:00.1 Audio device: ATI Technologies Inc HD48x0 audio Though I believe the second one is for a port on my video card, and thus the first one seems to be the one actually in use. If it matters at all, I'm running 64-bit, and am currently dual booting with Arch Linux (which has its own audio issues, and I was putting off tracking down because Ubuntu worked fine).

I've tried some workarounds like adding an audio entry in the registry but it did not work. I think that the problem is related with the pulseaudio driver...

I have a Creative Labs SB X-Fi sound card and I am getting a lot of crackling & popping with it. Plus I have to kill and restart pulseaudio a lot. Does anyone know of anything that can be done to help this out? I have the latest F12 kernel and rpms installed.

I've got some sort of problem with my sound configurations (I think). There's this crackling/disturbance (with an ocational beeping sound) coming from my headset whenever I insert a headset or speaker. Turning the sound off doesn't make it stop either.I'm running Ubuntu 9.10 on a Acer Veriton 3600GT (some years old). Please note that I'm not all that familiar with Linux yet...Typing aplay -l in Terminal returned the following:

Subdevices: 1/1

So whenever I start-up and after I enter my passphrase for cryptsetup (before login manager) I hear this crackling sound from my speakers constantly throughout usage.
While watching a movies or playing Youtube videos it's less noticeable, but when I'm typing up or working it really gets frustrating.
I've tried to figure out if pulseaudio was the culprit. uninstalled and rebooted yet crackling and pops continued. I haven't yet altered or messed around with ALSA or snd_hda_intel driver. But I did notice while using Audio Mixer, muting the speakers section stopped the crackling ...
So I guess the problem lies with Alsa or snd_hda_intel or both?

When I installed fedora 11 I had bad sound which crackled and crashed. I followed this guide -http://forums.fedoraforum.org/showthread.php?t=225660 - which fixed my issues in videos playing on the web and in VLC. However; in the last few days sound has bugun crackling again in VLC while playing videos (web is fine). All updates have been applied and I am running 32 bit Fedora 11.
Also totem when playing video crashes, freezes, crackles etc while playing videos though playing sound files is fine with no issues. Any ideas how I might solve this and get my sound while playing videos back to how it used to be?

I've had a snap, crackle, pop coming from my speakers since I put this machine together, even now, with no reason for any sound to be coming from the speakers. Additionally, the crackling only becomes worse when I play ANY audio regardless of player or source, however the sound does just drop for a few seconds and then back and then off again when there is SUPPOSED to be audio. I understand not working at all, but "kinda" working is more confusing.
I'm running slack64 with the with an updated kernel from current, even though the rest of the machine is stock 13_64. The problem was the same with the original 2.6.29.6 kernel.

My microphone in skype is crackling on Debian Wheezy stable 7.5 ... It is OK on Windows so it is obviously not the hardware to blame.
I have tried already all the options I could find regarding this on the internet, by changing in /etc/pulse/daemon.conf:
Code: Select all resample-method = speex-float-10
OR
Code: Select all resample-method = speex-float-1
My output was also crackling but I solved it by changing:
in /etc/pulse/daemon.conf:
Code: Select all default-sample-rate = 48000
flat-volumes = no
in /etc/pulse/default.pa:
Code: Select allload-module module-udev-detect tsched=0
I also tried starting skype with
Code: Select all PULSE_LATENCY_MSEC=30 skype
Without any success. Now the output is perfect, but the microphone in skype (haven't tested it elsewhere) is crackling.

On Maverick, I noticed a couple of days ago when I started an MP3 of a single tone recording it had a 'crackle' for about a quarter of a second at the start of playback. I initially thought there was a problem with the recording but I have noticed it is universal and I now pick up it is happening on some songs too (particularly if they start on a single note, not all songs seem affected).
This is a problem if I double-click a sound file which I open in Totem, it's also a problem if I start playing an affected track on Rhythmbox, it also happens if I just hover the mouse to start playback, but interestingly any problematic file if I load into Audacity there is no problem at all and the file plays correctly.
I doubt anyone else will have noticed this bug as it is so small and I wouldn't have picked up on it had I not been playing a single tone recording, but now I have picked up on it I can detect it all the time which is annoying. Has anyone else noticed at all?

I'm having some issues with audio crackling/buzzing when turning up the volume, or on songs that have overclipped / overdriven parts, which doesn't happen on Windows (on it those sections are just "dampened"). Is there some certain settings in ALSA that are used to deal with this? Or is it something specific to the driver for the hardware? Speaking of which I'm using some integrated audio which goes by the name of Intel ICH7, and the chip itself is Analog Devices AD1981B.
I'm only using ALSA, without PulseAudio, and I've made sure the volumes both in the media players and under alsamixer aren't turned too high (PCM is at 47% and "Headphones" -- what is "Master" on Windows and on other soundcards under Linux -- is on 22%), so it isn't an issue with the software mixer being turned up too high. Also I'm using a pair of quality headphones (Sony MDRV55) so it's not an issue with the analog audio output either. I've also tried multiple other headphones and the result is the same.

Installed azureus vuze from the terminal. Im not thrilled with it and want to remove it.I used the comand sudo apt-get remove azureus and Code: sudo apt-get remove vuze it then listed a buch of files no longer needed so I erased them as well. The program is still there and operational. I tried the above again and it says that they dont exsist. I even looked for them in synaptic and the software center with no luck but I expected that. What am I missing?

I need to write a script that can search up to 3 parameters and find all files containing those words. then display them and the amount of hits it got.if the first parameter exists, then we can assume we are looking for the word supplied.if the second parameter exists, then we are looking for files with both keywords.if third parameter exists test the second parameter for the values ('and', 'or', '-v') and search accordingly. These are the only values accepted as the the second one when 3 parameters are present.
lastly, if there are zero or more than three parameters echo as an error and when 3 parameters have been entered we echo an error when the second parameter is not one of the following: 'and', 'or', '-v'.

I upgraded from 9.10 to 10.04 this past week. Foolishly, I tried to finish it quickly, and let grub fiddle with my Vista volume, sdb1. I realized it after I agreed. Shucks! Now, my computer won't boot unless I go to the ROM. A bit of history, my original 9.10 install was on a formerly dual boot 160 Gig IDE drive. This one was really just my main Ubuntu drive (sba1). I would have gladly gotten rid of the useless NTFS side of it, but never wanted to bother. The terabyte SATA drive is my Vista volume (and general data drive). It has no Ubuntu nothing on it. When I wanted to boot to Vista, I would boot to sda1 via GRUB2 and then select Vista. It would then come up to the Vista Bootloader, and I'd select Vista and boom, things worked fine.Then I did my ugrade. Somehow, the original grub on sda1 got messed up. I have no idea how. I get the somewhat familiar error: the symbol 'grub_puts_' not found and unceremoniously dumped to a grub rescue>_ prompt. Great! I can enter the ROM and tell it to boot from sdb1, then grub comes up exactly like before and I can select Ubuntu and 10.04 comes up!
So my MBR on sdb1 has now been ruined by GRUB2. Now I know I should never have allowed GRUB to write to sdb1, but why did it also mess up sda1?To make matters worse, I can't use the various boot-to-LiveCD solutions rather common out there. I downloaded the ubuntu-10.04.1-desktop-amd64.iso and burned it. But since I got my new 25" monitor for Christmas, I guess it's too much for the poor old LiveCD disk. I upgraded via the Update Manager, so the video wasn't an issue. Now, when I boot from the LiveCD, the screen turns black and that's it. Take the disk out, reboot, and you're back to the ROM or that beautiful grub rescue>

Small office... 20-30 computers all windows based. xp/vista/windows 7. 3 Servers running ubuntu 10.04... 1 domain controller, and two file servers with samba. We want to be able to login once in the morning, and then not have to worry about users/passwords at all throughout the day. So I was thinking that I could setup a PDC and then make the two filservers both BDC's and use ldap to authenticate everything. Would this even work out? and is there a better way to do it?

When ever I have sound coming into line in I hear a crackling noise. The noise also ends up coming in through my Mic as well so everyone in Skype gets to hear it as well! If there is no sound coming into the line in then the crackling noise goes away. I have attached a recording from my Mic with sound coming in line in. or not I can't figure out how to attach it. Have a link instead[URL]..
