Multimedia :: Ubuntu Crackling On Starting MP3 Playback / Sort It?
Oct 22, 2010
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 am having a really annoying problem here. Every time when I use my Computer while listening to music, or watching a video, I get some sort of crackling in my Audio. For example, playing a mp3 with Rhythmbox (or Banshee or Totem, doesn't matter really) while browsing the web is just horrible, every time I scroll down the page (Mouse wheel or keyboard) I get that noise. Just listening to the music while not touching the Computer works just fine. It does not seem to be CPU related, my reason being: I can max out my CPU, rendering a 3D graphic and still have crystal clear sound, but browsing down some big file-folder at the same time will distort my audio.
The same goes with games which are a bit on the high CPU side, like Nexuiz with high graphic settings: No sound problems at all. I am using my on-board sound, which lspci lists as VIA Technologies, Inc. VT1708/A [Azalia HDAC] (VIA High Definition Audio Controller) (rev 10), pure ALSA setup, no pulse/esd or anything of the like installed. Switched to unstable to see if a more up2date kernel or updated alsa would do the trick, it didn't! I am running Debian Unstable - 2.6.37-2-amd64 kernel, Gnome-Desktop. Here's what I did to make my sound work in the first place, since my squeeze didn't recognize my sound-setup out of the box:
To make my onboard sound system-wide default I created /etc/asound.conf:
# Modified as per [URL]
pcm.!default {
type hw
card VT82xx }
ctl.!default {
type hw
card VT82xx } .....

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.

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.

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'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.

I tried to install Ubuntu 10.10 Server 32bits and 64bits but each time the installer stopped at 45% during "Starting up the partitioner" with the message "Scanning disks".
I installed Windows 7 64bits on the disks without problem.
I installed IPCop 1.4.20 successfully.
However, I tried to install Fedora 14 32bits and 64bits but it also stopped (ie crashed the partitioner) during the "Install To Harddisk" via LiveCD.
Similarly, OpenNode 1.0 also crashed with a bug report that has alot of python error messages. All mean nothing to me.
I even tried to partition the disks first via Fedora 14 LiveCD. Still the same thing.
Has anyone encountered this sort of problems before? If so, any resolutions?
Could this be the problem with the SATA2 disks?

I am using debian squeeze and did an aptitude upgrade yesterday. Today I've found that VLC won't play any video; the files open and the audio plays, but the video is black. The aptitude log is below.
I note that VLC received a security upgrade a few days ago, but my suspicion is that the source of this problem is more likely to be the upgrade of libavcodec52 from version 4:0.5.2.6 -> 5:0.6.1+svn20101128-0.2. I believe this upgrade came from the debian-multimedia stable repo I have enabled.
Does this sound right, and what could I do to fix my VLC playback? This is new territory for me, and I'm slightly surprised that such an upgrade would come from the stable branch of debian-multimedia (although I know this is not an official source).

Yesterday I fresh installed Ubuntu 10.04 64 bit LTS on my Toshiba Laptop. This is my second time with Ubuntu so bear with me. I got everything working even the webcam but it won't play dvd movies. When I go to the DVD player icon and try to open it...its won't because it doesn't recognize the dvd format.I have searched but only end up trying stuff that didn't work for it. I guess what it needs is Codec's.

I upgraded from Ubuntu 10.04 to 10.10.
I could play a particular DVD in totem without any problems immediately before the upgrade. Immediately after the upgrade I could not play that particular DVD. I got the error message below code...

I recently upgraded my girlfriend laptop to 9.10 and now, for some odd reason, when she plays DVDs on her laptop (the most recent attempt was the latest Harry Potter movie) the movie would play back fine but the colors for everything were way off. I've re-added the medibuntu software sources to her system and applied all available updates but it didn't help.
This problem did not occur on my own computer when attempting to play the exact same DVD.

Is there any way to make Ubuntu play sound like Windows 7? I mean when i, for example, listen to music in Windows 7 the sound is much clearer and besides that i can use room correction to obtain a better surround feeling, but when i listen to music in Ubuntu the sound is not very clear and it sounds like stereo even though the sound is played back through all the speakers (the bass is also a little bit to high).
So far i've tried installing the alsa driver and modifying the output levels of each channel, but didn't quite have the same result as the room correction feature in Windows, and the sound wasn't any clearer either. Note: I have an onboard Realtek soundcard and Logitech x530 speakers

I've been running into issues with VLC crashing now and again, particularly when seeking through the current item using the bar (as opposed to Ctrl-Right Arrow/Left Arrow); it may have happened in a few other spots, but that's usually when I'm not at my keyboard. All files are stored locally on my HD, mostly .avi video. For the most part, when I'm using VLC, I've got Firefox and maybe a Nautilus window running as well. CPU use, Memory use, and System load stay pretty well down (and I've never managed to get my swap usage above 120MiB of the 1.2GiB on the Swap partition).
I've tried removing and reinstalling VLC, no dice; about screen lists Ver 1.0.2 Goldeneye. A side effect of this is that, until I restart the system, the screen is unable to be put to sleep at it's timeout; in the notification bar of the top panel, an icon appears and (if the mouse is left there) a little box will appear with text as follows:
Session active, not inhibited, screen idle.
If you can see this text, your display server is broken and you should notify your distributor.
Please see [URL] for more information.
The URL there listed doesn't have any information that seems to be useful, but, I'd presume that VLC does something to prevent the screen turning off while it's playing (a situation where most folks aren't going to be typing or mousing around), which is undone when VLC ends cleanly (and re-opening, then exiting doesn't fix it).

On almost each mp3 file I try to play, VLC will "lag" during the first seconds. There may be some screeching noise. It looks like vlc can't keep up with the bitrate, and it "skips" some bits.
This doesn't happen with totem (the default media player).

I have tried loading/playing (many different) dvds via VLC / new install of 10.04 (on a laptop through which I had been able to play / burn / rip dvds until I "upgraded")...this is what transpires:
Errors:
Code:
Playback failure:
DVDRead could not open the disc "/dev/sr0".
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///dev/sr0'. Check the log for details.
The log reveals:
Code:
dvdread error: DVDRead cannot open source: /dev/sr0
main error: no access module matched "dvd"
main error: open of `dvd:///dev/sr0' failed: no access module matched "dvd".

I have a DVD that I am trying to burn to a disc. What I have is a VIDEO_TS folder. First I burned just that to the disc and it plays fine in my standard DVD player, but when I try to play it back using Ubuntu's Movie Player, it acts like it is going to play for a split second and then goes into stop mode. So, I tried burning the disc again, but this time I added and empty AUDIO_TS folder to it. Still plays fine on the DVD player, but in Movie Player it plays the menu. Only it doesn't show any image, just a '>' symbol that you can move with the mouse.

I'm having some issues with DVD playback. Blu-ray playback is not an issue (at least no more than it is for anyone else using Linux), but when I try to play a DVD the video is garbled and choppy, same as the audio. (see attached picture).
I'm using an Asus BR-04B2T blu-ray reader and an Evgo nVidia gtx460 with nvidia-current drivers.
I removed the blu-ray drive and put a friends dvd drive into my computer to test and see if it's the graphics card or the drive, and the DVD player worked perfectly, flawless playback, so I know it's the drive.
Also the drive is not faulty. Both DVD and Blu-Ray work fine under my windows 7 partition.
I forgot to mention, VLC behaves the same as all other players, as shown in this picture. Also you can almost make out that I'm trying to watch the Simpson's box set my friend got me.

I'm sorry if this was asked before (i know it was but never worked for me) 2 days ago I installed ubuntu 10.10, my very first linux OS and I immediately fell in love with it.The only problem now, is tearing during video playback (I'm a perfectionist with a thing for fine details, so this is literally killing me)
I have nVidia 9200M GS (HP laptop)
I've set nVidia setting to sync vblank and disabled it in compiz
I've also disabled PowerMizer..
I love the system to give up some vsync issues in moving windows, but i just can't get over video tearing. I'm ready to install anything, change anything, even do a new clean install to get it working. UPDATE: Installed SMPlayer, works fine but drops couple of frames every 5 secs or so (more annoying than tearing lol) is there any specific settings that can fix that?

I am having music playback issues in lucid right now. When I try to play music through any player, the music plays at a slightly higher speed - roughly 10% faster (a 3:17 song finishes in 2:5. I tried installing 10.10 and had the same problem, and I just went back to 10.04 with a fresh install and still seeing the issue. Is this a common problem for people? My sound hardware is the following as reported by lspci
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 50)
For reference, I also have 2 other boxes in the house running 10.04 with different sound hardware with no issues. Their hardware are:
00:06.1 Audio device: nVidia Corporation MCP55 High Definition Audio (rev a2)
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
