[Solved for now] Sound pops on playback

I did what the wiki said to stop the sound from popping when playback starts, but it continues to pop. Anyone having similar problems--any advice would be helpful too.

It would be nice if you told us what you did and where you got the instructions from . But from what I'm presuming it's an alsa problem so did you follow the instructions from here ?

[Solved For Now] Wireless Not Working on HP Pavillion 15-n278sa

EDIT: I seem to have fixed it for now by following this tutorial, I don't know how long it will last though: http://askubuntu.com/questions/337785/w … -c55-a5281
Hi there guys,
I have been having some problems with my Wireless under arch on my lapotop, which is a HP Pavillion 15-n278sa. I've had the wireless working twice before, but a reboot broke it both times. The Ethernet works perfectly fine. The first time I have no idea how I got it to work, it was a combination of a bunch of different threads and eventually I modprobed the wireless adapter and it worked (this no longer works).
This is the output of when I try to connect to the wireless using wifi-menu:
Job for [email protected] failed. See 'systemctl status [email protected]' and 'journalctl -xn' for details.
So I run systemctl status [email protected] and journalctl -xn and this is the output of the both respectively:
Systemctl output:

This one being the wireless controller:

If there is anything more I can provide I would happily do it, I really need the wireless to work under this laptop. I know it works, I have had it working under Arch and it works under Ubuntu no problem. I am not sure if it is a driver problem, or if it's a problem with netctl. It looks more like a problem with netctl as after netctl updated it started working, and after a reboot it broke again.
Thanks so very much everyone,

Time Capsule internet drop-out problem.... Solved (for now....?)

I am new here, but i would like to share my experiences with a problem a lot of people seem to have here aswell.
I got home last week after being abroad for work for two days, and noticed i couldn't get on the internet again. My system uses an iMac, TC and an internet modem i got from my ISP, which is a Motorola modem.
Hooked the TC up to the modem via ethernet and this has been working without a glich for about 2 years now. I first noticed the problem on my iPhone which was unable to get on the internet. Connected to the network just fine, but no internet. Very strange, as i had a solid green light on my TC.
Checked the internet on my iMac, and i found the same problem. Did a reset on the TC and the modem, and things seemed to be ok again. But.... after about 20mins. internet was not working any more again. By now i was getting rather frustrated, because in the AirPort Utility it said everything was working the way it should, including a solid green light on the TC.
Been going over everything i could think off. Soft reset, hard reset, going back to factory settings, resetting the modem. Just resetting the modem, just resetting the TC, resetting both at te same time. Nothing seemed to work, the problem kept coming back! Downgraded the software on the TC, upgraded again. Nothing.
Strange thing was, i hooked up my computer via ethernet directly to the cable-modem and internet was just fine, so no problem there, which was confirmed when i called my ISP (which is great... as long as there is no problem)
After 3 days i finally called Apple, and they were ok to help me. For free just for once (next time i will have to pay 49euros!!) and told him about my problem. He gave me all suggestions i already tried, except changing channels on the TC.
After the call i tried doing that, going from channel 1 to 6, but still... after 20 - 30 mins. internet would drop.
But.... i put it on channel 7 and for now it is working great again. (no loss of internet for about 36hours!!)
This seems to be THE solution for my problem. Apparently, one of my neighbours put up a device which was interfering with the signal of my TC, which caused all my problems!
For now i am really happy everything is back, up and running and i thought i just let you all know about my problems, and solution, because this forum has been a great help!
And... before i forget.... i am running firmware 7.3.2 now... because i read a lot of problems about 7.4.1 and things are running great for me now !!
Hope this little story can help someone else..... try change the channels TC is working on !!
Good luck to you all!

64bit Adobe Square & Hulu playback issues [SOLVED] for now

Back in mid September, I installed Adobe's flash player "Square" preview release. All was good including perfect Hulu playback.
As of this weekend, Hulu wouldn't play, and without a message as to why.
And yes, I'm aware of, and experienced the Hulu playback issue with the prior test version Adobe had available prior to Square.
Square fixed Hulu playback for me, but just temporairly.
Anyone else having this issues or is it just my system?
Version: Shockwave Flash 10.2 d161

Found this: http://forums.adobe.com/thread/738761?tstart=0
Apparently, RTMPE isn't functional yet, which Hulu now requires.
Hulu and Amazon which depends on RTMPE aren't currently functioning because there are some 64-bit libs that need to be integrated into the branch. That particular bug is set ToFix, but i can't speak to the timing.
Encrypted Real Time Messaging Protocol (RTMPE or RTMPTE) is a proprietary protocol created by Macromedia used for streaming video and DRM. It reportedly allows secure transfer of data without SSL. It is implemented in flash player 9.0.115 and some versions of Flash Media Server 3.
And this: http://forums.fedoraforum.org/showthread.php?p=1403271
Re: flash-plugin-10.2.161.23-1.x86_64.rpm
As of yesterday, Hulu is blocking the 64-bit plugin again.
This time it doesn't even give an error message, the video window just doesn't display.
I've gone back to the 32-bit plugin, which still works there.
Interesting, Hulu is blocking both 32- and 64-bit Linux versions of Square,
even though the release notes say that only 64-bit versions fail to support content protection.

SOLVED (for now) MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

For MAC OS Snow Leopard 10.6.8
I downloaded the display driver update from apple support and it didn't fix the problem. I had to download gfxcardstatus-1.7.5 and change the driver to Intel Graphics instead nVidia (wich is the one that crashes the screen)
Hey, guys from apple, please solve the nVidia trouble.

The black screen issue on mine just started in September 2014.

Not able to install BB Link - maybe solved for now

Hi Guys,
first - please excuse my english if there are maybe some mistakes, it´s not my foreign language - i´m from Germany and want to give some response for all of those, who got the problem with the install-problem for this software.
I also got the problem with different errors while trying to install the actual version of link on my computer (Win 7 64bit).. I´ve got a previous version of linked installed while trying to update - main error during the installation was the missing network source - the installer meant.
I´m working in the 2nd-Level IT-Support, so sometimes i know what to do..
After many many tries and searching for potential solutions in different forums i got the following solution:
A clean deinstallation of the previous version is highly recommended. If you are not able to deinstall it through the control panel, try to uninstall it with a different uninstaller - in my case the IObitUninstaller from PortableApps was helpful. http://portableapps.com/apps/utilities/iobit_uninstaller_portable
It used to try the normal Deinstallation, when this is not successfull he is looking for another way where you´ll get listed all of the link files on your installation folder and your registry - try to deinstall it that way (be careful, backups are usefull..). If this also doesn´t work - give the microsoft fixit install and install tool one try - http://support.microsoft.com/mats/program_install_and_uninstall - i´ve got this link from another thread here.
Somehow this wasn´t the complete solution. After the Deinstallation (i suggest that one of these should be successful) the latest version doesn´t like to install. Different errors on my machine, f.e. network source not available, another try got the respond "there´s already another installation running" .... and many more .. forced me to check the possible reasons. With the process explorer i checked the running tasks - there was the windows installer still running some kind of installation of link.... try to kill these tasks (in my case this wasn´t successful - they are restarting immediately) - maybe you´re luckier then me. If it won´t work - Reinstallation of the installer is a possible solution. The Way you could to that you´ll find here: http://www.optimize-your-pc.org/fix-windows-installer-error-1719 - please be careful if you try to use the reg-tweak as described. It is also possible that you´re not able to find the key described /HKEY_LOCAL_MACHINE\SYSTEM\CURRENT CONTROL SET\SERVICES\MSIserver\WOW64)- don´t worry ´bout that. I also needed to reinstall the installer.
at least - the source file i´ve downloaded also does not work. Tried to download it a few times and the installation still didn´t work. After that i tried to use an alternate Source for downloading.
After all these steps i was able to install it in the latest version.
maybe this helps the people with the same problem out there.
Thx for reading, over and out.

Dankeschon !

[SOLVED for now] Suspend-to-RAM broken - immediately turns on again

Hi everyone,
Susped-to-RAM was working flawlessly on my lenovo IdeaPad S12 Netbook until recently:
When I Suspend-to-RAM (via KDE) the system apparently suspends correctly but then it instantly turns back on. So the problem is not that I cannot suspend but rather that the system turns back on immediately after suspending. Usually the system could only be turned back on by pressing a button on the keyboard or the power button (not by moving the mouse or opening the laptop lid).
I unplugged all attached devices, including mouse, keyboard, power supply and network but that doesn't help.
I'm pretty clueless what could cause this and would be happy if someone could point me in some direction. This used to work until recently but I don't know what update broke it.

Update:
The system stays asleep when I unload the ehci_hcd and ohci_hcd before suspending (unloading just ehci_hcd as suggested on other sites doesn't work).
So some kind of usb device seems to trigger the wakeup. As I said before I don't have any usb devices plugged in, though.
Since unloading the usb drivers is not very convenient I would really like to find out what exactly causes the wakeup. I don't really have a clue where to start, though.
I use a script to unload ehci_hcd automatically when I suspend (my issue is slightly different, it doesn't immediately come back, it just doesn't finish suspending and gets stuck on a black screen)
I'd imagine a script someone similar to this would work:

Installation problems solved for XP SP2 systems.

I've been pulling my hair for days trying to install SC2, but had no luck.
The installation process DOES have a bug. Use the following tactic in addition to disabling any firewalls and virus programs:
Right-click on the installer file and select 'Compatibility' . Click 'Run this program in compatibility mode:'. Finally, simply select Windows NT 4.0 (Service Pack 5) mode.
Problem solved for now. Hope this helps.

This is very interesting akian ty - I will definitely try this at the weekend. I can install and run on a laptop with XP SP2 - and it had previous versions installed on it. However on the desktop PC I have not been able to install.
My problems have been with opening ports and appserver not starting. I will post back here how I get on with your tip. Thanks and also for the other suggestions that people have tried to help me with.

System Info:
Linux ArchBoxMTD 3.10.7-1-ARCH
AlsaMixeer v1.0.27.2
Pulseaudio 4.0
Audacity 2.0.3 (official package from Arch)
But, when I record with Audacity, playback (before exporting), is shoddy. I noticed my dB levels lower than normal when monitoring my audio/recording in Audacity. Before I remember I had to even LOWER the default dB level of recording in pavucontrol/sound center. I've done this many times on Arch, and I have had no new hardware. I have tried changing the output/input device on the main screen in Audacity several times to no effect. I never had to before. Now, on Arch I have always had to set the inital dB recording level via sound prefs, not via Audacity as the "Input Volume" slider on Audacity was always grayed out, but never an issue before.
If you need additional information, please let me know.
Thank you

first of all, if your pulseaudio setup is working for you there's no reason to break it really..
historically, the reason for using sound servers like pulseaudio over alsa, is that some sound cards don't support hardware mixing with alsa, which means you coudn't play audio from eg. audacious and youtube at the same time. Nowadays alsa has software mixing support (via dmix plugin if I'm not mistaken) so Its not usually an issue any more.
I have very limited experience with pulseaudio, and can't be sure of the differences. Generally I believe alsa can do most of the stuff pulseaudio can, but if you've ever looked at configuring alsa, you might know it could be a real pita especially in more advanced setups. From my limited experience with pulseaudio, I think it could be easier to set up on some cases and often just works out of the box. I could also have some audio over network capabilities that alsa might lack, but that again is just my assumption.
also I'm pretty sure pulseaudio is required for some desktop environments like gnome.
just use whatever method works for you
I remember having that EXACT issue back in ~04-06. That was the most annoying thing, and the reason why I started to use pulse back then. Oh I know the pitfalls of alsa, which is why I understand pulse co-existing on Arch's cinnamon package setup. Cool, well thanks for the advice!

Using iTunes on your computer, open Preferences (under the leftmost item in iTunes menu). Choose "Devices" on top. Find your backup listed there, highlight it, and select "Delete Backup".

I had sound on my computer last night but when turning on this morning there was no sound. It is not muted. Any suggestions. Also, when I try to run an event in IPhoto as a slide show, it shuts down.

Just to clarify, does iPhoto unexpectedly quit or does your computer shut down? For the sound problem, try here:

[Solved]Alsa funkiness (sound breaking)

(Note: I originally thought this was a steam issue, but turns out it's not only steam that can break my sound (see the update on the bottom))
I get an issue with Steam where I get a short (less than 1s) sound on repeat/loop (usually it's some part of the message notification sound, or a trailer that I was watching) sounding a bit like a broken record, randomly occurring after keeping steam open for long periods of time in the background. Only fix I've found so far is to restart steam.
I have the Enlightenmen 18 Window Manager.
Notable errors:
Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element

AL lib: pulseaudio.c:612: Context did not connect: Access denied
I don't have any reliable method to reproduce the issue, and it does not seem to output an error of it's own in the terminal output when it occurs. I have noticed that this is more likely to occur when steam has been open for prolonged periods. I am not using pulseaudio, just Alsa. I also noticed when I was running a Wine game (not through steam) that this issue occurred, and it seemed to contaminate the sound outputs for whine too (I got like a "double" sound for every sound effect the game played). If the sound was completely broken on steam and making a loop like I explained at the start of this post and then I close steam while the Wine game is running, the sound from steam will remain until I shut down the game too (i.e. seems that this isn't just breakage internally in steam, but in alsa itself)
The one thing I have tried to solve this was install lib32-libpulse, this did not seem to fix the errors nor the problem. I imagine installing pulseaudio could fix this problem, but pulseaudio downright hates my sound card, so I would rather not use it.
I also have two other issues too that are less severe.
1: Mouse cursor sometimes gets locked in steam instance (Right clicking will show the steam context menu, pressing "stop" in that context menu will solve the issue. This sometimes happens when I use "Ctrl + C"(copy) or "Ctrl + V"(paste) when I'm typing in the discussions)
2: Fullscreen videos will not go fullscreen (they will only fill the steam window)
Update:
I found a bulletproof way to make a similar issue occur.
If I open facebook in firefox, and get a message notification while I am playing a movie in Cmplayer (my media player of choice) the sound in CMplayer breaks (but firefox's sound keeps working normally)
Update2:
I was rather desperate to get this fixed so I installed pulseaudio as much as I despise it, the quality of my audio is damaged by it, but this problem was as I suspected fixed by installing it. I am guessing pulseaudio is set up partially to prevent issues like this one, but I would relaly prefer not to have it. This does not rid me of all the errors however (reference_audio_renderer errors persist) but it does create a new error for steam:

I always had to have an asound.conf in the name of upmixing 2.0 to 5.1 This is the content of my asound.conf before I made the changes. I also had a problem with a game where I had crackling noises on 48khz so I had to tell alsa to force 96khz (or 44.1khz but since my card supports 96khz that's what I went with) to avoid that.

Random Audio Crackling and Popping on playback in FCP and Pro Tools

Hello All,
In both Pro Tools LE through an original MBox (with latest firmware), via USB and Final Cut Pro using an Edirol USB audio interface, I get random cracks and pops in different places that aren't in the actual audio files. They are not in the waveforms, and they never happen in the same spot twice...just random. There's no telling when they will be heard, but they are very loud and sharp, and I'm afraid of damaging my powered monitors, not to mention my nerves as I'm in the middle of an intense sound design for a film.
I've tried looking up this topic, and I've seen some topics mentioning sync/clock....like it's a problem with sync being generated internally, as opposed to using an external word clock generator. I never had this problem before on my older dual 2.0 PowerMac (PPC), and I really can't spring for a word clock generator right now...anyone else experience this with their Intel Mac Pro? I've looked for new firmware updates et al, but everything on the computer is up to date. This is really driving me nuts right now.
PowerMac G5 Mac OS X (10.4.3) Dual 1.8
Mac Pro Mac OS X (10.4.8) Dual 3.0

Interesting point about the winter/static. The only thing is that I never had those problems before with the same setup on my older dual 1.8 PPC G5 PowerMac, through several winters.
My current setup is a dual 3.0Ghz Intel Mac Pro with 3Gb of RAM. the RAM is the right kind and it has checked out as a-okay via numerous tests. The video card is the stock NVidea 7300 GT. For Final Cut Pro and general audio playback, I use an Edirol UA-1EX usb interface http://www.roland.com/products/en/UA-1EX/index.html (w/ updated drivers and all) hooked up through one USB port. For Pro Tools LE 7.3.1, I use an original Mbox, also updated with the latest firmware and all (got rid of the distorted noise problem with firmware update v22), also hooked up to a USB port. I used this exact same setup on my previous Dual 1.8 PPC G5 PowerMac with no such issues for several years. Both interfaces are routed to a Mixer, and onto my monitors. I don't think it's the mixer that's doing it because it didn't ever crackle/pop with my older G5, and still doesn't, which I still use for other things, but routed through the same sound system. I can understand the use of an external clock generator and such, but for many years, I never had this problem with random crackle/pop on playback with other computers that did not use an external sync/clock device. I would think that a computer as new and 'advanced' as the Intel Mac Pro would offer even better results than previous models. Again, the noises aren't printed onto the actual sound files, they come up randomly, but most often after adding a fade/volume change/effect and playing back.
I have just installed a PCI-Express USB 2.0 card for use with both the Edirol and MBox, just in case it was an issue with the built-in MAC USB ports. I will see if that helps.

Suggestion for Brightness & Sound Dusplay problem.

After having upgraded to OS X 10.4.6 I started noticing I had no over my control of my brightness and sound display control. I reset my PRam but it did not solve the problem. I checked the keyboard controls.
However I did discover that by holding down the "fn" key and pressing the required keys, I can now control the brightness and sound control.
However I still have no backlight keys control.
Hope this helps.
Still loooking for a fix for the backlight keys.

When the video pops on once the Captivate .swf starts playing and the FLV within comes up, the output window opens and displays the following. Wonder if this will help.

Win 8.1 update - sound popping / glitch in MetroTube and all APPS when scrubbing video

My phone Nokia 1020 was working fine. I then downloaded the over the air update for Win 8.1 and Cyan on Thursday 7th August from O2.
Since then I have experienced a loud popping / static noise when playing video in all apps (except StoryTeller)
Using built-in speaker:
When I play video in any App with a video scrubber and I scrub the time-line and realise the scrubber it makes a loud click or static pop.
It happens in everything including:
Mytube
Metrotube
Tubepro
Photos App (i.e Microsoft one - playing a recorded video in they all now have a loud click / static pop)
Xbox Video App (i.e Microsoft's own App)
Using Headphones:
There is no load click (It plays how it used to)
The odd bit is using the speaker and playing music tracks (mp3s etc) and scrubbing there is no static popping click it plays fine.
Video In Web Browser Fine:
Playing YouTube Videos in the web brower there is no popping / static click noise.
I have just downloaded 'xVideo' App and played a HD Music video in it and used scrubber and there is NO loud click.
Sound Glitches in Audio Clips at end of recordings in all these Apps:
Babbel - Learn Spanish
Coolang - Learn Spanish
Zeemish - Learn Spanish for Beginners
its really annoying and makes trying to listen and remember pronunciation of words difficult and frustrating. Phone was ok before Microsoft Windows 8.1 update now have this issue and issue with static build-up causing popping when fast forwarding through
videos. :( I am feed up
Conclusion:
This is software bug? please can anyone help/advise me on how to fix this and if anyone else is having same glitch with 8.1 update :(
All I can think of to fix is to somehow downgrade to Windows 8 if that's possible? :( *update its not possible using Nokia Recovery as it puts back Win 8.1.
It is a Software bug introduced in Windows Phone 8.1 update. It effects everything! including
Microsofts own Video Xbox App and
Photo App. See other people frustrations on this issue, its been going on since April!!!! please can you fix this is ruining my Windows Phone experience:

Microsoft need to fix this Video Popping urgently, I have tired to want to like Windowsphone but they keep going backwards and I am loosing faith.
If is not fixed soon i.e next few months I will never buy a Windows phone again and will recommend the same to friends and family. I had so much hope and expectation for 8.1 update :( love the Notification bar and battery icon but I can't live with
all this. :(

Hello,
You should ask in the
Windows Phone forums on the Microsoft Community forums.
As the Microsoft Community is on a different platform, we cannot move the question for you.
