[Pulseaudio] Pop sound when the first stream starts, auto-suspend?

Hi,
I've been having a popping sound issues whenever a Pulseaudio sink was opened. At first I thought it had a link with the power saving settings of snd_hda_intel, so I changed those two settings:
power_save setting = 0
power_save_controller = N
Sadly, it doesn't change anything.
I also tried to disable auto-mute in alsamixer. It didn't work.
Then, I tried to investigate on pulseaudio's side, and figured the sinks are disabled when they are idle, so I commented out this statement in /etc/pulse/default.pa:
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
However, if I do that, the device will still be suspended when the last stream ends, but won't come back to life except if I select the device again in pavucontrol while a sound stream is running (super weird).
Any leads? I'm a bit desperate...
EDIT: I'm experiencing what's been described here: Red Hat - Bug #520403 - but the solution they proposed does not work for me. I also followed the guide for ALSA Setup on the wiki, and read the section talking about Popping Noises, but nothing works for me, I un-muted the Line-In too. FYI, my audio codec is a Realtek ALC892.
EDIT 2: Noticed it does the same thing when I mute the volume.
Thanks!

Right, an array of unsigned integers to be exact. You would have to look at the code, either in your sources or here and here. They may have changed somewhat, but I doubt any drastic changes. First link is to linux 3.14 version. At least I assume it gets passed on directly, if that really is the case, I do not know. Just try it, hardware damage risk is minimal.
Looking at the mask, I think it takes up to 31 samples. So try with 1, 2, 4, 8, 16, 24. I may be very well wrong about this.
Since I already have 0 and 1 in the 'trial matrix' I'll add 24 only. Adding the combinations with 2, 4, 8, 16, 24 is too much for me

On most keyboard layouts (also on the Polish programmer one) hyphen is one key one keystroke, where underscore is two key one keystroke, therefore more error prone and less efficient.
Wow, I didn't know that! What do you know! Linux being bitchy even about capital letters made me think it would be even more bitchy about '_' vs '-'.

Anyone else getting a random "pop" sound when the screen comes on?

It's random and doesn't seem to affect anything else, but every so often when I raise my wrist to view, a small pop sound emits from the speaker. It doesn't happen every time, and the speaker itself works fine. The only water that has come into contact so far has been from washing my hands.
Anyone else experiencing this?

I have this happen too! 42mm Stainless Steel.
I thought at first it was just the strap or strap connectors clicking when raising my wrist to view the screen, but today I isolated it to the speaker on the device. It doesn't happen every time, but enough that it's a mildly annoying quirk.
Also, if I take my watch into a very quiet room, hold the speaker slits to my ear, I can hear extremely faint white noise coming from it when the screen is lit. So for some reason when the screen turns on on the Apple Watch, the speaker wakes up too, and when the speaker wakes up, it sometimes emits an clearly audible popping noise.
Also of note, the speaker functions perfectly fine when on. Notification sounds and calls sound crisp and clear, just for some reason it pops when turning on the circuitry that controls the speaker.
My device has never touched water.

Ipod makes weird sounds when the hard drive runs

my ipod video is making weird click clak sound when the hard drive starts running. Is this normal?? HAs this happen to anyone before?

HEY!!!!!! I wasnt alone. Amazing. I had the same experience with my new Black 30 Gig iPod 5 Gen. It had a 3 second delay, made lots of HD clicking noises. And worse after a few hours of usage, forgot 240 of my 270 songs that had been transferred onto it. This was all happening on the first day! Wow.
Im sure glad to hear I was not alone. The sad thing is, Amazon is going to take 4 weeks to return my money to me. I will never again by a hardware product from Amazon.com. It simply takes too long. As far as Apple iPods are concerned, I believe they need alot of design renovation to put it frankly. Here are my complaints about the 5 Gen:
1. No Screen Brightness Controls. A major no no.
2. 3 Second Gaps between songs. What?
3. The trackpad on the iPod is far out of alignment. Not sure who supplied these, but the Mini was far superior to the 5 Gen trackpad. The traction was severly off kilter.
4. 284$ for an iPod that forgets 240 songs in a blink of an eye? I don't think so Apple. Get a grip. Woz was correct when he stated you all use crapy supplies for your parts.
I thought he was kidding?!
This was my first and by my choice, last iPod experience to be had with Apple. They are cute, but software/user level wise, they need alot of work.

My iPhone 5 have the glass popping sound when I press on the top left corner of my phone but I don't know why, I don't see any visibility of the glass coming out. My friends all told me to not exchange because after all the software is perfectly fine.

My phone just turned 2 months old. But in Singapore as long your phone is under one year warranty I can still go for an exchange at the respective telco, but my friends all suggest me to not change now cause after changing it'll be a refurbished set instead of a brand new one.

Clicking/popping sound at the beginning of tracks when going to next track

some of my songs have clicking/popping sound at the beginning of the track only when I hit the next track button
if I let the track end the pop/click won't happen
any idea what this is?

Re-import one of the of the problem CDs in a lossless format, such as AIFF or Apple Lossless. Play a little to verify that the tracks are good. Then use iTunes to convert them to AAC.
Verify that those new tracks are good, and if so, you can then discard the lossless versions and keep the AACs.

The Pop Up when I first turn on the computer telling me there is a Flash Player update - Is this actually from Adobe? Is it probably malware?

The pop up when I first turn on the computer that tells me that an update for Flash Player is available. Is this actually from Adobe or is this some prospective malware to be avoided? It pops up even before I log on to my ISP.

Hi Tom,
If you have a Windows machine, this could be a valid dialog. If you have your Flash Player configured to notify you when an update is available, when Flash finds an update is available it creates a registry entry to display the notification upon log in. If you'd like to verify if this is valid, please take a screenshot of the dialog window and post it here. Also, when the dialog displays, open Task Manager and look for a FlashUtil_VersionNumber.exe process. Get the exact file name and post it here as well.
Alternatively, you can update Flash Player on your own by going to get.adobe.com/flashplayer. Once Flash Player is updated you should not receive any more updates (unless you elect to receive notifications at which point, the notification will display when an update is available). If you use multiple browsers, you'll want to visit this page with each browser, as it's configured to detect the OS/browser and offer the appropriate player type depending on the browser.

Audigy 2 Value randomly pops/clicks when the computer is just idling.

EAudigy 2 Value randomly pops/clicks when the computer is just idling.; I can't figure out why the I hear random popping and clicking when I'm doing absolutely nothing to the computer. Typing this right now doesn't seem to cause any popping. It usually happens when I'm not really doing anything to my computer. This was happening with Creative's drivers and software so I switched to kX drivers, but that didn't help. When I first got my computer (Asus A7N8X-E Deluxe) and got the Audigy 2, I had no problem with Creative's software/drivers at the time, no popping had occur until I installed an SATA HD. PCI latency tool helped at the time. Then I had to go through a reformat and after the reinstallation of Windows XP, the popping started occuring randomly. After my motherboard supposely didn't want to POST anymore, I bought another one which was the Epox. And same problem occured even though I reformat and reinstalled windows.
Right now, the only thing I could think of that the SATA HD and Sound Blaster cards don't mix well together. But none of these are sharing resources. I did not want to try decrease any hardware acceleration at the moment, will there be any difference in sound or performance if I lower the acceleration?
Here are my current specs,
Windows XP Pro SP3
Amd AthlonXP 2600+ @ 2.2ghz
GB DDR Ram
ATI x800 xt AIW
Epox 8RDA3+ Pro
Running Sata HD and IDE, SATA is the master dri've.
Some other info,
The sound card is not shared by any IRQ
PCI Latency Tool didn't help when I tried to set the latency from 32 to 64
Bios is updated
Nforce2 drivers are updated
Klite codec pack 4.5.3 installed
kX drivers used instead of Creatives?
Onboard sound is disabled
Dxdiag did not find any problems
Keyboard is connected to PS/2 to USB adapter

I have a imac g3 dv se, snow and after about 10minutes of it booting it makes a popping sound and the turns off, then it wont turn back on for another 5-10 minutes

i have a imac g3 dv se,500mhz, snow and after about 10minutes of it booting it makes a popping sound and the turns off, then it wont turn back on for another 5-10 minutes any suggestions?

Actually sounds like classic symptoms of a failing PAV (power-analog-video) on that model. Historically that's the weak spot in the G3 iMacs.
The lack of active cooling in the G3 iMac puts a lot of heat stress on this board and they eventually fail from overheating. Right now the board is still working as long as it's cool--it only fails when temps inside the computer rise.
About the only way to preserve the computer's life is to mount a 120mm fan directly on the case where the handle is--that's the exhaust port. The fan has to be positioned to PULL air out through that vent. It's an ugly solution to the eye but it has been done around here more than you would think.
Also make certain the bottom of the computer is not blocked. It the computer is sitting on a tablecloth or placemat, or there are loose papers on the desk under the case, it cannot get enough air into the bottom-mounted air intakes. Make/find some blocks to set the iMac a minimum of one inch (2.5CM) from the desk and move anything that can be "inhaled" from under the computer.
Even with such measures, the PAV board will eventually fail and be unrecoverable. It's a good time to start saving for a newer computer.

Popping sounds in the multitrack in Adobe Audition CC

I've been using Adobe Audition CC for a week now and have been having some problems with it. Sometimes there would be random pop sounds during the multi-track. The random pop sounds would sometimes come at certain sections of the multitrack, but I wouldn't hear them later. I would play the individual audio files and sometimes they weren't there. Does anyone know what could be wrong? Do I have to change some settings? I ran Adobe Audition 3 a few weeks ago on my Windows 8.1 system and never had any problems with popping sounds . With CC I get pops for some reason. I have a custom made computer that is supposed to have high performance. Is there anything I should change in bios mode? The multitrack that I'm using is around 40 minutes, and is on 11 tracks. I don't know if that has anything to do with that.
The computer I have is a custom made computer desktop that I custom made for working with music. It's an i7 and the most powerful computer I have ever owned. I have serious doubt that it's my computer. My computer is new and runs fast. As I said before, I'm running Windows 8.1 and it didn't have any problems with popping sounds when running on Adobe Audition 3 previously. I think it probably has something to do with bugs in the program itself. Has anyone experienced these problems? If so, did you fix them? Or does Adobe plan to fix them? I have contacted Adobe once through email and sent a complaint through Adobe Audition's support system and heard from nobody. So far, Adobe Audition has not sent me any patches or anything. Adobe Audition CC is insanely expensive. I'm paying around $220 or $240 a year for a program that already has serious flaws.

Hi there,
(My first post! I signed up/logged in specifically to ask about this problem, which I am also having.)
I am using an old Mackie mixer -> MBox 2 -> iMac. I have used this same basic setup for last few years, and this problem is sudden and new.
It sound like digital clipping/distortion, but is clearly not happening during the peaks of waveform. The input to Mbox is clear thru headphone monitor, I can't hear anything - but when played back, intermittent and audible pops/hits are happening.
My suspicion is that it is from the USB to the Mac; there are three USB inputs on the iMac and since the Mbox is powered via USB, I think the noise is being introduced there. I tried two outta the three ports (guess I should try the third - why did I stop there? Oh right - coffee!) So far I seem to have best luck when no other programs are running, restart the computer before every session, but otherwise I am just crossing my fingers!
I'll check back on this thread, as I need this ghost OUT of my machine! ~ Jim

Crackling and popping sound when playing music and watching youtube videos

there is a crackling and popping sound when i watch videos on youtube or play music/videos using vlc media player and windows media player. recently it has gotten to a point where it happens when windows is starting up or even when the laptop is required to play a sound for example when i plug in a removeable hardware such as thumbdrives

Hi @donnabail ,
Thank you for visiting the HP Support Forums and Welcome. I have read about your HP 2000 Notebook and getting a buzzing or popping sound while playing music and watching Youtube videos. Try performing a hard reset.
When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook that might have caused this.
You can try this
1. Right click the Speaker icon in the bottom right corner.
2. Click Playback Devices.
3. Click Speakers.
4. Click properties.
5. Click the advanced tab on the Properties window.
6. Change the Default Format drop-down to the highest quality.
7. Apply the properties.
8. Click OK to close the properties window.
What happens if you right click on the video while playing a video and take the check out of hardware acceleration. Shut the browser down and restart the notebook.
Have you checked for an update on the Active X.
Please let me know how this goes.
Thanks.
Please click “Accept as Solution ” if you feel my post solved your issue, it will help others find the solution.

My Mac got hacked. I was working on a word document when the computer suddenly started typing meaningful sentences on its own that describes how the hacker is skillful. At the that time I was on a password protected wifi and file sharing was off.

This is the first time I get hacked this bad. I was working on a microsoft word document when the computer suddenly started typing meaningful sentences on its own that describes how skillfull the hacker is. At the that time I was on a friends wifi network that is password protected (not sure about the encyrption), the Os X Firewall was on. I was using the admin profile, however, file sharing was off. I'm very careful not to install any suspecious 3rd party software.
So far I have verified permissions and fixed some errors there, and changed passwords.
Do I have to erase/format my computer and reinstall the Os? If so is it adequte to use the internet recovery tool or will it use old and possibly infected EFI/Root files?
Would appreciate the advice of all the Mac experts out there. Thanks

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo launchctl getenv DYLD_INSERT_LIBRARIES; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; launchctl getenv DYLD_INSERT_LIBRARIES; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

I have two hard drives on my mac 10.5.8 power pc and hear the clickking sounds of the first hard drive and think that it may be dying, can I install everything on the other hard drive also and wait for the first drive to die before i use the other drives? Or, what is the best way to handle this?

I do not know what you are waiting for.
I'd make a backup of your important stuff before cloning the entire disk.
Carbon Copy Cloner will copy your startup drive to an external firewire drive. You can boot from the external drive to verify that you have a good clone. When you upgrade your existing startup drive, you can at any time boot from your external drive and go back to your existing system.

SuperDuper is the wildly acclaimed program that makes recovery painless, because it makes creating a fully bootable backup painless. Its incredibly clear, friendly interface is understandable, easy to use, and SuperDuper's built-in scheduler makes it trivial to back up automatically. And it runs beautifully on both Intel and Power PC Macs!
