Static / Hiss Audio Issue

Lately , I have been facing an issue with my audio , ever since i moved to 10.8.1 , i have been getting static on all audio - Youtube , Itunes extra , i tried everything from formatting , downgrading to 10.7.4 to changing my headphones , Please help ?
I am a DJ/Producer so audio is like sacred to me . I have a Mac Book Pro 15 Inch I7 , upgraded to 16GB RAM , the Version before the Retina Display Version of MBP. I have also used an external audio interface , i am having the same issue but on a smaller scale.
Thank You all for your Support.

Are you using the old usb 1.1 multimix or the new 2.0?
Are you still using 10.5.2?

7925g phones static/hissing and roaming issues

Hello,
We've been having an issue for several months now with our over 200 7925g phones. Nurses are complaining that the phones have static and will drop the voice of the other caller and several times need to repeat the conversation. We have confirmed several scenario's. It occurs when both callers are on 7925g inside the coverage areas in the hospital; between 7925g and 7940 desk phone; 7925g and Nortel desk phone. We've tested on 802.11a and 802.11b/g. I do see a difference when on 802.11b/g however still get a hissing when connecting to a different AP.
4 - 4400 controllers, 6.0.202 firmware
1 - 5508 controller, 6.0.202 firmware
234 - LAP1131AG AP's
6 - AP1131AG AP's
7 - LAP1142N AP's
3 - LAP1310G AP's
AP's are on 6.0.202.0 firmware
7925g's all are on 1.3.3 firmware but we have a select few that we are testing at both hospitals with the newest firmware 1.4.1 and still same results.
235 - 7925g phones.
We have followed the 7925g setup & deployment guide, WLC Config Analyzer and made sure all checks were made. The only setting we plan on testing this week is changing the CCKM authentication change which was recommended. Currently we are WPA TKIP
We have disabled the higher rates (36-54) on the 802.11a.
We also have AirMagnet VoFi analyzer which is showing issues when roaming from AP. The alarms indicate a one-way audio issue and points to the AP's and phones power not matching. We have our Tx power level on the controller to automatic, Max Power Level at 30 dBm, Min. at -10 dBm, power Threshold at -70 (WLC Config Analyzer recommendation). The phone TX Power is set at 8 dBm. Call Power Save Mode has been tested with both None and U-APDS/PS-Poll.
We have a case open with Cisco TAC and she has requested debugs from our controllers. I have sent over 7 and she is not coming back with anything solid and not much help so far.
Our tests between 802.11a and 802.11b/g (RSSI setting on phone Auto-a and Auto-bg) have shown better with the bg mode but still static and/or hissing.
Any help would be greatly appreciated! Thanks.

Thanks!
We finally had an awesome Cisco Engineer on our SR. We straightened out the code and now have the correct 1.4.1.1.1.7 ES image and also configured CCKM.
We are currently testing with about 20 phones before we deploy it to over 200 phones.
Below are the steps we took and so far the tests have resolved the issue.
1. Downloaded & installed the 1.4.1.1.1.7 code on the 7925g's.
2. Changed the Scan Mode on the device in Call Manager to 'continuous'
3. On the Controllers, configured & implemented CCKM on the voice WLAN only.
4. Set the Radio Policy for the Voice WLAN to 802.11a only.
5. Only using channels 36, 40, 44, 48, 149, 153, 157, 161 on 802.11a
6. Disabled the 6,9,36,48 & 54 Mbps rates for 802.11a only
7. Configured the phone with the new voice SSID with CCKM, Security Mode as EAP-Fast, & 802.11 Mode = Auto-a.
We are following up with these test users next week so I will post if this fixes our issue.
Thanks for all the assistance everyone!

Intermittent Static Hiss w/ Slow-mo Distorted sounds (SB Audigy

Hello all!? Having a bit of an issue with an old SB Audigy 4 [C000] of mine. Bought it about two years ago, took it from the old desktop and put it into the new one. Had no issues with it until yesterday.
It seems that it's liking to suddenly emit a static hissing noise at random intervals, and when this hissing is going on, any audio coming from the computer is slowed down. I've never had this issue before, and I'm wondering if someone on here has had similar issues. These symptoms eventually end, but it's quite annoying because I have to wait for it to stop until it decides to go away. It also seems that it is somewhat affected by whatever I'm doing at the moment - minimizing windows or hovering the mouse over something that displays a text box sometimes makes it stop for a short second, before it picks up again.
Thank you in advance.

...except that I'm using Windows XP 32-bit with SP2.
The only thing I can think of that would be causing this is that the WiFi USB adapter I installed yesterday was causing some sort of IRQ conflict or frequency disturbance. I've since plugged it into a different set of USB ports than where it originally was - maybe that'll fix it (I hope).

Audio Issues with MacBook Pro (Late 2008)

I am seeing an occasional issue with my MacBook Pro (Late 2008). The Audio will go out... and instead you will just hear static-like clicking sounds when and audio even happens. For example... when you have the up/down volume notification on... and you change the audio volume.. you hear clicks. Or... when you open up a file that has audio.. you will hear the static-like click when the audio starts to try to play.
The work around per-se is to completely shutdown and turn the notebook back on. A simple restart does not seem to fix it... it looks like the system needs to have a bit of energy drain first. Which... worries me that this is a hardware issue and not a driver issue.
Wondering how many others are seeing this???

I went to and Apple Support Center last week and I asked some questions about audio because my MBP was having troubles too. The tech told me audio issues are very frequent on these machines and sometimes you have to change a part of the soundcard. He also added you have to bring the MBP to a support center if you're having the problem several times - in my case I'm waiting the next "crash" since I had only 2 issues so far... If you're under warranty go for a check up and see if it really needs assistance. Goodbye

Static/Cracking Audio When Using Chrome

Lately I've been having an audio problem with Chrome. I'm getting static/cracking audio whenever I watch any type of video with audio in Chrome. It seems that I only have this problem with Chrome and not any of my other browsers. Any idea on how to fix this?

There are a couple of solutions offered in this thread for Google Chrome audio issues.
Good luck.

New P67A-C45 (B3) - Static/hissing noise almost in sync with HDD sound

I just bought a new New P67A-C45 (B3), fixed everything up, installed the realtek sound driver then i start to hear the static/hissing noise from my speakers.
The noise seems to be in sync with the HDD activity.
I research online and it seems that not only I have this problem, quite a few people having the same sound chipset on a Gigabyte board are also facing the same problem.
But all solutions is in the direction of mac, stating that a v262 driver have solved the problem.
Anyone got any idea about this? I am rally very irritated with the static/hissing noises coming from the audio..

Have a look in your manual of the included accessories with your mainboard. Note the 'Back I/O Plate'.
For this I think you all are talking about the back panel right? One of the tabs is touching the exterior of the ethernet port. I assume it should be correct?
Quote from: sjay on 11-April-11, 07:48:46
What they mean is you need to remove the graphics card and unplug the cables from the motherboard and remove the motherboard itself, check the grounding screws (The screws that the mobo sits on and in to which you screw the mobo screws into to hold it down) and make sure that all of them match the holes on the mobo, if there are any that don't match Remove the standoff because it is causing the improper grounding you are experiencing. If you are missing any ("only using two"?) and have standoffs laying around, add the standoffs to the holes that fit.
I did this just last night and it fixed my reboot problem after I had done everything via bios and OS to try and solve it.
Done as well. The base plate in my casing for the motherboard was just fitting for it. I do not need any stand-offs, there were six bumps that align with screw holes nicely.

MDR-1RBT static hiss on the right side

My MDR-1RBT makes a low but noticeable static hiss on the right side. It comes and goes, but is audible most of the time. Is this normal behaviour of the MDR-1RBT? I love the headphones, but the hiss is a bit irritating when listening to audio books etc.

Please follow the troubleshooting steps here if the sound is cutting in and out on one or both sides of the headphones or is experiencing static hiss.
However, if none of the steps will work, please reach out to Sony Germany who has a separate community which can be found here for best assistance.

Sound / Audio issues with Google Chrome

Hi guys,
I have this audio issue with a new Macbook Air (2013 base model).
When I stream audio / video (eg podcast, YouTube, NBATV) via Google Chrome, there is the static or clicking sound which you could hear both through the built in speakers and through the headset.
Brought it in to the Apple Store yesterday and they acknowledged the sound on Chrome. HOWEVER when using Safari, this clicking / static sound is no longer audible. I can probably record an audio clip to demo this further. The genius concoluded that this is probably an issues with Chrome or codecs that its using rather than the actual laptop. No replacements at this stage.
I have an old MBA 11” where this issue does NOT occur.
The hesitation in using Safari is Flash. Some video streams such as NBATV, which I watch quite frequently use Flash. Chrome handles this quite well, with no separate installs required.
Has anyone else encountered this? Not sure if I can pursue this issue further with Apple.

Chrome shockwave flash plugin issue causing sound problems on the macbook:
Shockwave Flash 11.5 r31 (old version)
Shockwave Flash 11.5 r502
disabling r31 solved it.
Many people have checked their chrome plugins and found they had two plugins enabled. They disabled the older one and audio is perfect.
-Go to chrome://plugins
-Click and expand +Details in the Upper Right
-Check over the flash files.
-One is version 11.3.31.222
-Disable the odd version and reload the flash content
For some reason, CHROME has allowed two flash plugins to be enabled at the same time, and clearly the older version is the one causing the problems.
go to "Chrome://plugins" tab. Click “Details” at the upper-right corner of the page.
Find “Shockwave Flash” listing for the integrated plug-in on the page and click the corresponding “Disable” button. To identify the integrated plug-in, see the table of plug-in filenames above.
Find the “Flash” (or “Shockwave Flash”) listing for the system plug-in on the page and click the corresponding “Enable” button. To identify the system plug-in, see the table of plug-in filenames above.
disabling Shockwave Flash 11.4 r31 resolved the problem for most people.
When people double checked: if they re-enable Shockwave Flash 11.4 r31, ....the distorted / broken audio happens again.
Hope that solves it for you

Bootcamp 3.1 and imac windows 7 64bit update not installing. Audio issues!

After many days of work getting the windows 7 working in bootcamp in my imac 27 (still with audio issues) I eagerly awaited the bootcamp update and imac updates.
Neither will install.
Then I find that according to tech support as of now I have to reinstall Windows 7 again for the updates to work!
It took me 5 full 8 hours days to get all my scientific programs installed and working, now I find I can't even simply update the drivers I need. I don't want to reinstall.
My only issues are audio.
Here they are:
1) The headset jack works fine on the Mac side, but in Windows 7, it causes the i7 intel CPU to go crazy. There is no CPU spike on the mac side.
2) The headset jack in the imac is a trrs jack. The same as in the iphone, a tri-band jack that has three bands, two audio out channels and one mic in channel. A trrs headset works fine on the mac side with using the headset mic (as in iphone) rather than the built in mic. (this provides much better quality for sound recording). I don't want to use a usb mike.
In Windows 7 the mic part of the trrs headset does not work.
3) In Windows 7 when going into audio devices recording, no audio mixer shows up, so when I do video or audio screen capture the only way to capture the sound is through the speakers and then back through the imac built in mic, rather than directly through the unit. (terrible sound quality) On the mac side the mixer element works fine.
Now I find from other imac users that even the new updates for the imac on windows 7 don't address and fix the audio issues. I am sure not going to go through 5 more days work only to find the audio issues still don't work.
I need these audio aspects to work properly though!
I have tried to get drivers for the cirrus logic audio card, but guess what there are none available and cirrus logic doesn't even recognize the board or offer drivers.
I have many windows programs I must have for my scientific research!I bought the top of the line Imac with all the bells and whistles because Apple promised that the machine could run Windows 7 in bootcamp natively!
It doesn't. This has been a nightmare of problems.
Is Apple going to step up to the plate and make good on their promises?
Does any one have a fix for any of the audio issues, or know how to install the new drivers without a complete reinstall of Windows?
Installing a few sound drivers and software should not require a complete reinstall. Getting the proper drivers for the headset jack audio in and audio out jack should be the most basic of fixes. Making the audio mixer work should be elementary.
If you are an Apple tech person or an Apple user that can help on these issues, please do!
Thanks, Dr. Duke
An American profesor in Europe.
PS I will post this under Imac windows 7 updates without a reinstall and under
imac Sound issues.

On another thread a few people have responded saying that their imac has the same situation, the cpu is going crazy and the imac gets hot with headphones or speakers plugged in. But this doesn't happen in the mac side.
If you have an late 2009 imac and don't have these audio issues, let us hear from you. If you don't, lay out the problem here.
Here is my last two cents in to the inquiry.
Not only does the cpu run crazy but the imac 27 gets very, very hot. Since I unplugged the headphones, it runs much, much cooler.
Certainly, some Mac engineers should take care of this problem, it seems it is universal on all the imac 27's and from what I gather, the smaller screened cousins too.
Also, we certainly want a stereo mix option for audio in or out, or what is called "what you hear" or wave out. Imac is supposed to be much geared to multimedia apps.
Finally, the mic jack part of the trrs set up MUST be fixed! A lot of manufacturers are going to headset combo jacks as they call them, mic in and stereo out on the same tribanded plug. But, the old single jack for mic in and single jack for stereo out are two tiny parts of the hardware and super inexpensive for the manufacturer. Why in the **** to go to the "advanced" triplug if the **** thing doesn't work.
Mac has a great reputation. I hope they remedy these problems right away.
Anyone whose imac 27 or 24 whose headset plug is working correctly. Let us know! I don't think anyone's is, but I think that few people understand that their cpu is running so much faster with the plug in, plus few even understand the combo jack and the triband, or trrs audio jack! Out of 4 audio technicians I talked to, not one of them knew what a trrs jack was or that you even have a mic in jack as part of the headset jack!
When I told one senior that it worked on the Mac side, he didn't believe for a while, thought my sound might be recorded from the onboard mic, but I proved it to him by tapping iaudibly on my iphone mic headset and and it showing up in garage band clearly and listening to big difference in audio.
As for a usb audio adapter, I am in a neon light environment and find that those adapters are more sensitive to electrical interference. Besides I want to use the headset jack as it was meant to be used!
Thats it.
Again, if anyone using an imac 27 and windows 7 64 or 32 doesnt have these problems, let us know! We are all anxious for a fix!
Best to all!

SoftPhone over VPN audio issue

Having a "one-way" audio issue when IPC connects over VPN to any Main Office IP Phones (7960). Remote IPC (softphone) shows "0 Received" Packets, but the IP Phone shows them as being sent.
This does NOT happen if IPC contacts another IPC on a PC at Main Site, or any kind of phone at the other branch offices.
Have looked at all of the audio settings on the VPN IPC unit, they are correct.
Any ideas?

Try to sniff the Ethernet traffic during call setup at the CallManager. When Callmanager sends Call Control messages to remote party, it could send wrong IP address or UDP port as an RTP parameters.
Another components could block the traffic are firewalls. How do you have your VPN tunnel built? Do you use Cisco VPN Client? What terminates your VPN traffic at the central location? PIX, VPN3000 or Router? Traffic may go one way without a change, and some protocol FixUp may be triggered for this traffic on the way back. If you have access to firewall logs, check if you have any traffic dropped.
Good luck,
Mike

Logic 9.1.8 & Mainstage 2 - crashing frequently/audio issues

I have just uprgraded to this set up (though using the same sound card as I did on my Mac Book with Logic 8 & Snow Leopard prevously) - in order to avoid overloading which was happening on my previousl set up.. only to find that this new system seems very buggy - crashes frequently on Logic (Sudden Motion Sensor error - have disabled that now) and Main Stage freezes. Then a wierd echoey sound can happen - whereby any audio is echoed back from DAW, in Logic AND Mainstage.
I have down loaded two plug-ins/VST's since starting to use this new set up - an XILS Lab L.E. verision and a Crystal synth. I've downloaded the up to date Duet drivers from Apogee. (I have an Duet 1.5 that I used with my old set).
Have looked at the Console system log to try and understand what might be happening - it is FULL of text on occasions when Logic crashes - I am not tech savvy enough to unpick it though.
If anyone has any suggestions to help I would be grateful, thanks.
I do wonder if it is a Core audio issue though - given the echoiing that seems to occur...

My Ipad 2 external speakers does not work and headphones has popping sound. This all occured at the same time as my Iphone and Ipod headphones only played mono (no, the "mono" option is not on). How can there be audio issue for all these devices?

My IPad 2 external speaker does not work and the original headphones have popping sound when used. This all occurred at the same time as my IPhone and IPod headphones only plays mono (and no, the "mono" option is not on) with the original headphones, as well as, other headphones tested. How can there be audio issue for all these devices at the same time?
As you may have noted from the list of Apple devices I own, I believed in the Apple and the products it was producing; but it is hard to believe from my experience and the other voices within the Apple Community that we are all experiencing the same hardware issues. Especially since I recently, I upgraded to an IPhone 4g (no, my faith in IPhone 5 series is very little) and is experiencing the same audio problem as described above. So now, I am off to the Apple store again to be told that it’s a hardware problem on new IPhone. Really? Apple, what happen to the pride in the product you were producing?

Everyone does things a little differently. I love to "jam " along with iTunes ( or old Lp's) . Always have. That's where/how I've learned to play .
I'm sure leonieDF is giving a proper way to jam along on a keyboard with an iTune. He blows my mind all the time with what he knows. Nuff respects to him !
What I do is make a GB project I call "Jam With". I'll make several new tracks that are blank. Just has a few instruments named in the blank tracks. You can change those per song ...
Because I'm not concerned about changing the pitch / key.... of the iTune or the tempo ... I can simply play along with it.
Peace,
P. Dreadie

I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

I have a fix - or rather, a workaround.
WARNING: It is lengthy, but still far better than starting a new project from scratch.
I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
This will require:
A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too, as they will be extremely helpful later.
4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
6.) Once you are done with this, export your newly pieced together audio track.
7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
YOU'RE FINALLY DONE!!!
I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
DON'T USE IMOVIE EVER AGAIN.
I hope this helped!

My iPhone 5 is suddenly having audio issues through the headphone jack.

So this is a strange situation, and I'll try to explain in depth so that someone might be able to suggest a solution. As reference, I have an iPhone 5 that I purchased in late-February. I've had every other model of iPhone except for the first iPhone, so I am pretty familiar with the device. I used to be on AT&T, and switched to Verizon when I upgraded to the iPhone 5.
Two days ago, I was on a six hour road-trip, and I'd been playing my music like normal through my car's auxillary cable. After stopping for lunch, I went to plug my music again, but once the music started to play, I realized that only the drums were playing at normal levels while the vocals were very, very soft. I switched through a few different songs, and realized that all the songs were being played at different levels; sometimes the backup vocals were normal levels while the instrumentation and lead vocals were quiet, or vice versa. I decided to plug my iPhone in to charge, and when I did this, the audio levels were all normal. However, the iPhone was NOT charging. I removed the charger, and the audio went back to being weak and distorted. I went back and forth at this for a bit, trying to figure out what was going on.
Since then and after some testing, I realize that my iPhone will now only charge anywhere EXCEPT in the car charger (I simply use my USB cable that came with my iPhone and plug it into the power adapter I have in the car). This morning, I tested the audio in my home speaker system, and I had the same audio issues. Only half the song's tracks would be at normal audio levels, while the other half would be at a very quiet, almost nonexistent level. I tried plugging my charger into the phone to see if that'd make a difference, but instead of the audio going back to normal like it does in the car, the music stopped and there was just crackling and very noisy distortion sounds.
I'm super confused and not sure what to do. This has never happened to me with any of my iPhones. I am updating my software right now, and am hoping that that may help somehow. Otherwise, I'm at a loss. Any suggestions as to what I should do would be greatly appreciated!

Do the new iMacs have digital audio out through the headphone jack?
Yes.
