Weird static/high frequency sounds while streaming Netflix.

I am experiencing weird static/high frequency sounds while streaming Netflix. At first I thought it was my headphones until I pulled them out, then thought it was the iPad itself. I am now watching on my tv (apple tv) and it's doing the same thing. So far no issues on my Mac. Any ideas?

You're using the two pin connector to the wall socket, if yes, use the three pin.

High Frequency Sound Bug on iOS 8

From time to time I turn on my bluetooth headphones, put some music and almost get deaf by a super high frequency sound coming out from them. First time it happened I thought it could be the headphones, turned them off just to hear that strange treble sound (like an old Modem) coming out from the iPad speakers too, then I rebooted the iPad and it looks fixed.
Yesterday it happened again, but after reboot sound was kind of back but still wonky, like blown heaphones, when you cannot hear bass and it has a buzz all the time playing with the songs.
Looks like this is related:

Safari crash in agcore plugin while streaming Netflix

While streaming Netflix on my iMac, Safari crashes with great regularity with a message talking about the agcore plugin. Is there an upgrade for it or something? Only in the case, never had a crash otherwise.

...and when I try to post the entire crash log (for days now) the website says it is down and come back later .... cute ... posing in parts...

High frequency sound with K8T Neo-FIS2R

Hello!
I have the MSI k8t neo-fis2r mainboard with bios v 1.6 and sometimes it makes a horrible high frequency sound and I cant figure out why.
My system are:
amd 64 3000 cpu and
Corsair Value S PC3200 DDR-DIMM 512MB Unbuffered, Non-parity, 64Megx64, CL2.5
My other components does not cause the sound (that I have found out by testing).
I wonder if the ram causes the sound? Can you please help me. The sound is so bad that I cant use my computer. It only appers during heavy system load, and not in windows. It has nothing to do with my video card (because I have tried with several different cards). My bios settings are default values + cool and quit enabled. I have the core center installed so the progam controls the cpu fan.
I really hope someone can help me.

The sound does not come from the speaker and I dont think it comes fom the cpu fan either. I think it comes from the motherboard, ram or the cpu. When I dont use my mouse it is quit but when I clik it makes this sound. Can it be that I have to set all values in bios for ram etc. manually instead of automatic?
When it comes to other electrical sources I have a TV standing 0.5 meter from the computer. Could thins cause the problem? I did not have the problem with my old motherboard which was a MSI K7T Turbo2.
The sound usually appers when I am benchamarking my system. For example 3dmark 2004. Because of this I thougt there was a problem wiht my vga card but after a changed to a new one...the situation was just the same.

How large is your hard drive and how much hard drive space do you have left?
Please describe in detail all you have attempted to do in order to resolve the issue.

Using iPod with high frequencies

Hi there - I'm having treatment for tinnitus (high-pitched sound in the ear). There is a treatment where you listen to music interlaced with high frequency sounds which is supposed to stimulate the brain & the cilia inside the ear. They have CDs available but recommend not to use iPod. My question is, if you transferred the CDs using Apple Lossless would the high frequencies come through? Bear in mind some of these frequencies are up to around 14 KHz and there are all sorts of subtleties in the signal. One question is transferring it to the PC using Apple Lossless, the other question is playing it back on the 5G iPod. I'm also thinking of getting a Nano just for this - would it play it back OK? Thanks!
MacBook Pro 15", 60 GB 5G iPod Mac OS X (10.4.4)
14 iBook, 768 RAM, 60GB Mac OS X (10.4.4)

This is only my personal opinion, which can be wrong.
First, human can only listen to 20KHz most, thats why the CD's frequency response only cover in the range of 20-20KHz.
For iPod - the apple mentioned the following
iPod is designed to provide the best-quality sound. iPod has a powerful 60 mW amplifier so it can deliver audio as loud as you want. It also has a 20 Hz to 20 kHz frequency response, which means you can hear distortion-free music at the lowest or highest pitches. Even the iPod headphones are designed to give you the best-quality sound. The earbud-style headphones rely on Neodymium transducers, a rare earth magnet that significantly enhances frequency response and overall sound quality. Most other headphones use aluminum, cobalt, or ceramic drivers; at the same size, the Neodymium driver is five times as powerful. Because the strength of the driver increases the accuracy of the sound, the iPod headphones provide a high-energy listening experience while minimizing distortion.
To ensure CD-quality sound, be sure to use a compression setting of 160 kbit/s (the default setting in iTunes) or higher when you "rip" tracks from your CD into MP3 format, or 128 kbit/s in MP4 format (AAC).
Therefore, if you rip the music from a CD, it does not matter whether it is MP3, AAC or Apple Lossless, it will no reduce the frequency response, however, there is noticeable difference of sound quality from different format, of course with Apple Lossless format being the best, but much bigger size.

I can't stream netflix with an extra apple display ...

...on a MBP11,3 i7 late 2013 with Yosemite.
I just switched from 10.9 to 10.10 and my apple display 2006 isn't supported anymore for streaming Netflix, probably due to some HDCP issues.
Netflix only works with the display unhooked, yesterday (10.9) it all worked fine ...
Sorry Apple, I don't like this.
How can we solve this issue?
Tx

Already found a solution.
Apparently it is the HTML5/DHCP in Yosemite which causes the problem.
In Netflix preferences I unchecked HTML5, so it plays now on Silverlight.
That did the trick, I can use both my MBP screen and the Apple display again while streaming Netflix.
Easy fix.

When instant streaming Netflix on my Macbook Pro, the sound is very very low even when sound controls are set at highest level.

When instant streaming Netflix on my Macbook Pro, the sound is very very low even when sound controls are set at highest level. I do not have this problem when listening to TV or watching movies streamed from DishNetwork. I contacted Netflix and they had me install a newer version of their software Silverlight... this did nothing to resolve the issue. They were not familiar with the issue.

Well if your on 10.6.2, you need to software update to 10.6.8
Perhaps you need to adjust the Silverlight (Microsoft DRM video plug-in) sound level itself too
Run a check here to see if your current on your Silverlight (works for all browsers)

Use another browser like Firefox and see if it continues.
Try another video file. They all have their own sound levels too.

IPhone 5 making weird sound while using Viber

My iphone will start making strange low tone beep sound while using viber. Only when I close the app (holding it long at multi-task and clicking the X) will it stop. And then when I open it again it will start making weird beeps again. Please help.

Hey there kben,
I'm sorry to hear that your iPhone is having the same issues. This is not a known issue on the device so lets try and take a look to see what is causing it. Did you have this issue before the 7.0.2 updated? Please try a soft reset,http://vz.to/16Qv4Id and let us know if the issues persist.
If the soft reset does not work, I would recommend performing a hard reset on the device,http://vz.to/17aDIPT.
Let us know if you need any additional assistance.

Macbook audio stuttering while streaming from Netflix, Hulu, etc...

As of late my wife's 2008 Black Macbook 2.16ghz C2D has been acting up while streaming video. It first started with kernel panics, but Iocated the problem and relieved the Macbook of it. Now though after a hard drive erase to zero, a re-install of the OS, and an uprgade to the ram it has an audio stutter present when watching Netflix. I've checked practically everything on it. Even opened it up to check the hardware. Can anyone help? I ran this diagnostic from some help here in the forums.Can anyone see anything I'm missing? The help would surely be appreciated. Thanks!

You may have tried these suggestions before, but since I do not know the history here goes:
Looks like you have many plugins in your safari.
Disable all plugins except silverlight and try Netflix.
Try Chrome.
Once you run HULU the flash plugin it eat up hundreds of megabites of ram and then KEEP them for hours. It is a FLASH problem.
If you run Netflix (silverlight) after you run Hulu, you will run out of memory pretty quickly. The solution is to quit (not just close) Safari and then go to netflix.
Look at your activity monitor while you are using Netflix. How is your RAM and CPU usage?
Also Comcast (and the like) sometimes throttles your internet connection. Make sure your internet connection speed is still just as fast as it used to be.

Can hear a weird noise, almost like something lose or a static kind of sound

I bumped my iPad onto my knees and I can now hear a weird noise, almost like something lose or a static kind of sound - does anyone know what this is please.?

Can't tell what the noise is. Make an appointment at an Apple store to have your iPad examined.

High-frequency permanent distortion while recording through Line-In

Hi Everyone!
I'm recording music from my MiniDisc Player connected with Audio Cable to Line-In port. I'm using Real Instrumen track for this. When I record or even only listen to the music I hear permanent High-frequency Tone in background. I can record with no problems but my recordings are always accopanied with this distortion. I've checked it out also on Windows (Boot Camp) and there are no such noices. Somebody knows what could help? Maybe it's something with audio drivers?

In Multitrack view, Options, there is a Monitoring option where you should be able to set Audition Mix to Always.
This doesn't appear in Edit View.

High Frequency Noise from Headphones Out Jack

I have isolated the following issue to audio that is monitored via the headphones output on the back of my iMac:
I've been encountering a very high-pitched (and at times a cycling through high frequencies) noise when working with headphones to monitor audio. It's not the headphones and the problem is not limited to any single application. The noise is sometimes barely audible, and it comes and goes - but repeatedly and often. Sometimes the frequency of the noise is so high that I can imagine that those with poor or compromised hearing wouldn't even notice it. But the highest frequencies are still detectable - kind of like a faint ringing in the ears or a ringing television set that has its volume turned all the way down.
I've done everything I can imagine to troubleshoot the problem including asking a Mac genius, but nobody seems to have encountered this before. The noise can be triggered off (not masked) by any other incoming audio, but eventually it reappears. I will be editing a file, the noise will appear, and I can literally silence it for the moment by pressing a volume key or playing back a portion of audio.
Anyone else experiencing this issue? Is there a fix? I do a lot of audio engineering and this problem is very distracting. I haven't purchased any outboard gear to monitor with yet, so I don't know if I will hear this noise through an external audio interface or not. Thankfully, this noise isn't being recorded to disk. It appears to be a little monster that is haunting only the playback.

OK, It is very easy to reproduce the problem, just follow this steps:
(1) Insert any headphones to iMac.
(2) Do NOT play any iTunes or any application with sound.
(3) Now, set volume with the volume control keys on your keyboard, set it to the MAX.
(4) You can keep pressing on the increase volume key and every time you hit the key you should hear a sound.
Just as when the sound stop, you will hear a high pitch. Keep repeat step 4 and wait a while, then occasionally you will hear a high pitch sound that will last to longer than 30 seconds. The high pitch will be even easier to reproduce if you alternate before decreasing volume and increase volume by 1 level, each time, wait and you will hear the high pitch too.
This high pitch sound can be heard on external speaker plug into the headphone jacks too.
BTW, I turned OFF WIFI, Bluetooth, removed all USB devices except keyboard and mouse, adjust monitor brightness, they have no effect on the high pitch, it is still there!
I am going to call the Apple Care tomorrow. Will keep you guys posted.
