Dv7 beats audio makes a buzzing noise or some kind of speaker feed back

when i play music speakers sometimes make a buzzing noise seems to happen more on the bass side

I just installed a Mac Pro for a client. After a while I noticed this buzzing everyones talking about. It was especially bad after I installed two more internal drives. It seemed to come and go with HD activity. I pulled up the lever on the back of the machine when it was particularly loud and the buzzing went away. So like some others have noticed it's associated with the HD bays. I took the side off and adjusted the seating of the drives so they were exactly centered Now the buzzing is gone. I'll keep an eye on it. Maybe it will need some kind of silicone bumpers where the bay trays are metal to metal.
More research to come.

Maybe once every hour or 2 hours.

Rather than uploading the file, and await our responses, why not take the product back to Apple? My guess is that you accidentally changed an alert sound but, since you claim you didn't do anything untoward, who knows.

Satellite A30: HDD started to make a buzzing noise

Hello,
The hard drive has started to make a buzzing noise on my A30, I guess this is not good news, i.e. it is Kaput?
I downloaded HDDLife which tells me the hard drive is all ok, but I don't feel very confident.
I have backed up everything, and am thinking about a replacement hard drive.
So I have two Q's:
Should I get a new hard drive?
& if so, then would one of these be compatible?

Thanks

Hi
These are not great news.
3 month ago my HDD went dead. It was a simply head crash.
A day before it happened I have noticed strange sound coming from notebook inside.
But I was not sure if its a HDD sound.
So day after I wanted to start the notebook but the BIOS has not recognized the HDD.
So I have replaced a hdd and all was ok.
So take care. Maybe the same will happen to you.
I dont know if the 80GB will work but as far as I can remember some A30 was delivered with a 40GB HDD.
SO maybe you will be able to use a 60GB but Im not sure about the 80GB. You have to test it, you know
PS. The notebook should support the enhanced IDE (ATA-5) interface

I want to upgrade my 2007 Mac desktop to 10.5 Leopard. I am currently running on 10.4.11. When I put the leopard disk into the drive all it does is make a weird noise and then spits the disk right back out. It doesn't do this with any other discs, only this software. Is it still possible to update this computer?

Yes. Try Amazon.
Before you do upgrade to Snow Leopard, make sure your Mac meets the requirements.
Mac OS X v10.6 Snow Leopard - Technical Specifications
Make sure the disc you tried using doesn't have any fingerprints or smudges on it. The optical drive can't read the disk otherwise.
If your Mac won't read the disc, might be a good idea to rule out any problems with the startup disk BEFORE trying to upgrade the system.

Hp Stream Laptop makes weird buzzing noises whenever audio plays

My new HP STREAM Laptop that I have not even had for a month is making weird buzzing sound whenever I listen to things such as youtube, netflix, spotify, and pandora. It's happened since the first day I got it. Please advise.

Hi @asitzes ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue with the Video sounding weird or buzzing from your HP Stream Notebook PC. This could be the browser itself.
What browser are you using to view the Videos? This link will also check if it is up to date.
Have you tried a different browser?
Have you tried a regular DVD? Is the sound buzzing here?
Please let me know.
Thanks.

Audio makes buzzings/static noise

When audio is present, whether through the speakers or headphones, it is accompanied by static noise like a broken speaker cone makes- buzzes and static

Solved the problem myself; found there was an add'l clip causing the noise.

Why does my iMac make a buzzing noise any time my iPhone 5 is near it, even when the phone is on wifi?

It reminds me of back in the day when your computer speakers would get interference whenever your cell phone is near it, but this is just a constant buzzing coming from my iMac whenever i have my iPhone 5 near it (e.g. sitting on the table next to the iMac when it's plugged in). My iPhone 4 and my last few phones before that never did that. I thought it might have been the LTE signal causing it, but it does it when it's on wifi as well.
The sound is louder if I have messenger running for some reason. It's odd as ****! If anyone has any ideas, please let me know!

I forgot to add, it's a Verizon phone so it's CDMA. It used to be only GSM phones that did this.

Water pump makes a buzzing noise sometimes...

I have a watercooling setup, and my pump sometimes vibrates against the case inside which is really loud. Has anyone mounted their pump to a piece of rubber or other material to stop vibration?

most pumps come with rubber pads that go on the bottom of pump. If your getting vibration slap a little bit of rubber under the pump.

Beats-Audio / Sound System Enhancement dv7 / HP Envy 15

Beats-Audio - Sound system Enhancement
Test system
dv7t – 6100 Quad / Windows 7- 64bit
Beats-audio
Introduction - Cave Sound Caper
Edits 29-Nov-2011
This is a re-write of this document.
Parts One and Two have been flipped. It's a work in progress.
The purpose of this Post is to provide a method to enhance the sound coming from your onboard beats-audio speakers. The quality of the sound should improve - more importantly, MORE sound should be available. This is important if your system is suffering from lack of enough sound from the onboard speaker system.
This process does not make use of the Loudness Equalization enhancement. I tested the Loudness Equalization enhancement (for a different purpose). Setting the enhancement on my test system and then switching the enhancement off resulted in the “Low Sound” syndrome. It took some amount of work to recover from that mess. The Loudness Equalization enhancement, in this author's opinion, is to be avoided unless its use is necessary.
FLIPPED:
The original intent of this procedure has been to provide a means to increase the amount of sound available from the onboard speakers on notebooks that are equipped with beats-audio IDT sound drivers. The “Pre-work” on my original post was overwhelming the intent. If your system is healthy, and the only reason to read this document is to enhance the amount of sound from the speakers, there is no need to hash through the work to fix your IDT driver installation. I’ve moved that section to the end – IDT installation and other work has become Part Two.
You must have your IDT HD driver successfully installed into your system.   The proper IDT HD driver contains the beats-audio interface.
Where to Start?
If you have “No Sound”, the Enhancement process may not work for your system. Please take a look at Part Two and decide whether any of the steps in that section apply to you. It is not my intention that you waste your time trying things you’ve already done over and over to regain the sound on your system. There are many posts on the forum on how fix “No sound”. This post addresses only a couple of “No sound” issues.   There is one slight possibility – see the section about the controls in iTunes – make sure your sound players volume controls are not mis-matched – and make sure you didn’t turn something OFF by accident. If you turned off the sound while watching a movie and now the HDMI sound is off - Poof! You might not have any sound – anywhere. It's just something to check...
If you have “Low Sound”, you might consider reinstalling your IDT driver to see if the issue can be corrected: IDT reinstallation is described in Part Two.
SideBar: As of 24-Nov-2011
If you have a dv7t: check on your HP Software and Driver website for a new IDT HD audio driver. Depending on your model, there may be a new version of the IDT driver, BIOS, and other important updates.
Part One
Some Setup Checks and on to the Enhancement
Make sure all basic Sound settings are set to “Default” to start.
Portions of this procedure are "not of my invention". Full credit will be given later in the Post. This section explains how to increase the amount of sound coming from the onboard speakers. It also attempts to give you a bit of control over the kind of sound coming from the speakers that you may not have at the present. Beats-audio is great; frankly, though - it's made for external powered speakers or headphones... what you get from the speakers on the notebook leaves something to be desired.
A while back I found a very interesting post on the topic of increasing the sound from the onboard speakers. The post was originally written for the HP Envy15. I believe the post has merit - Part One of this procedure is based on that original post.
I tested the suggested combined actions – it does work (at least on a healthy system). The sound quality showed improvement over the standard “out-of-the-box” beats-audio setup and the quantity of volume increased. In other words, this procedure makes the sound coming from the onboard speakers louder without the use of the Loudness Equalization enhancement setting.
I would suggest trying this “Enhancement” under the following circumstances:
Sound Quality is Poor, or the amount of sound from the speakers needs improvement
Sound is quantity “LOW”*
Sound is absent AND you believe the absence is NOT due to hardware failure.** See note on iTunes.
NOTES:
* If your LOW sound issue is severe, it may ONLY respond to using the Loudness Equalization enhancement, in which case this procedure is not recommended for your use. The two are not compatible. See Part Two.
** If there is NO sound on your computer, it’s possible that completing this procedure may not result in any improvement. See Part Two.
Sound Controls – iTunes, Media Player
I would add to the emphasis on checking the volume on one’s iTunes setting. If iTunes volume is turned down, the notebook’s speakers will respond to that – turn up the volume in iTunes without adjusting the volume in the volume mixer and the sound on the notebook will not increase properly (or will suddenly jump). It’s a juggling act and one that must be taken into account when the sound is being reset.   Additionally, if you have other audio players on your computer – in addition to those mentioned in the post – be sure to check them for volume controls: it is important during a sound reset that all the sound players be in sync. If you miss this, you may not get your sound back.
Check for this mismatch in sound volume controls if you do not have sound or if you did have sound and, at some point you turned OFF your sound while watching a moving, a DVD, a something on HDMI controlled audio - and suddenly - you do not have any sound. Sound controls get tangled up. Sometimes you just have to unplug it, but you do have to check the controls.
Sample Rate and bit Depth
I do not use the suggested Sample Rate and bit depth of 24bit 96000 Hz. My system cannot tell the difference and defaults everything to 16bits – my recording equipment cannot discern the difference.   My ears lack sample rate sophistication.   I’ve left my dv7t Quad sound, Default Format (sample rate bit depth) at 16bit, 48000 Hz (DVD Quality). Sounds fine and it’s where most of my crummy recordings are set anyway. Don’t lose sleep over this one.
Where’s my Taskbar ICON?
A couple of HP forum posts have mentioned the loss of the beats audio icon from the Taskbar tray – the icon should restore itself if one can force the IDT driver to reinstall. Without the IDT driver, beats-audio is not going to work. Assuming the driver has installed and one can reach the beats-audio panel from the Control Panel, THEN it’s possible that for some weird reason the Taskbar icon didn’t reset. It might be possible to try and force a reload of the beats panel controller into the Taskbar. I think this is the file.
For a 64bit system:     C:\Program Files\IDT\WDM\sttray64.exe

It took me awhile but I now have the sound level about 3x what it was to start with. Try these tweaks:
Sound Enhancement Procedure
Control Panel > Sound > Playback > (Highlight) Speakers and Headphones > Configure
New Window ‘speaker setup’ > Test (should hear sound L/R) > Next >
           UNCHECK ‘Front left and right’ (if checked) > Next > Finish

            Enhancements > bass boost > settings > 80 Hz / boost 3db > Apply
             Tone Controls > Bass +1 Treble +3 > Apply
             Advanced > Default Format > 24 bit 96000Hz > Apply
NOTE:
After this DO NOT use the Beats control (Fn + B) or it will reset the tone controls.
HP dv7(t)
Taskbar > beats-audio panel
OR
Control Panel > Beats Audio Control Panel
        Listening Experience > Graphic Equalizer > Custom
        -1, +8, +10, +8, +9, +9, +9, +8, +9
Remember that these are suggestions – start here and re-adjust later as desired.
LEFT SIDE
Make sure Beats Audio is CHECKED
        Click the “Music” radio (round) button
        65, 65, 85, 65, 65
NOTE: The Left Side settings are somewhat arbitrary. The “Center” setting is higher – this provides the most sound and should be set higher at least initially for testing, especially if your system has sound issues.
The next section is partially excerpted from the original Post – Remember: JJ’s post was written for HP Envy15 – please adjust your results accordingly. Edits have been made for readability.
Control Panel > Beats Audio Control Panel
Playback > Speakers and headphones > Arrow above Speaker symbol and Select Small Speakers
Select Equalization> Select 'custom'>
Adjustments for this are mainly to boost the signal level in the preamp so we get higher volume while not distorting the sound from the tiny built in speakers.
My setting values are as follows: left to right;
-1, +8, +10, +8, +9, +9, +9, +8, +9, +10
MAKE SURE TO CLICK SAVE WHEN DONE!
Note: Do not crank up the Bass (31hz) control or it will overload the speakers which can't reproduce this anyway, you can even turn down more if you have distortion at high volume.
Check that the slide controls for 'master' and 'speaker symbol' are all the way up.
This should make a big difference in sound volume and quality, and there is one last way to get louder sound. Depending on what you use to play back your audio you can adjust the program’s sound settings or EQ controls also.
In iTunes the EQ has a 'preamp' slider which I boost to about +6, this increases the output level while leaving the EQ settings alone (make sure to check the turn EQ on box).
Windows media player: you have to raise all EQ levels equally (not too much) to boost without affecting sound quality.
In general it is not a good idea to use more than one EQ system in an audio signal or you get more distortion, so don't adjust the EQ curves or bass/treble on more than one device. I chose the Beats / IDT EQ to make the tonal adjustments because it is the audio driver program and preamp that outputs to the speakers, so it should have the best sound quality.
Any adjustments before the preamp that add distortion will just be amplified, so go easy on adjustments in your play back programs.
Finally, when you play your audio,
Sound > Open Volume Mixer >
Make sure to click the Sound logo in the Taskbar so the slider pops up>
Click ‘mixer’ then you should see all the sliders for your devices;
You can independently adjust the levels for the right mix.
If you open the Beats panel and minimize it then a mixer slider also shows for this and you can dial in the effect of the EQ settings.
Headphones:
One last thing; When listening to headphones you will need to increase the bass EQ setting (since headphones can reproduce the low frequencies) in the Beats panel or I just change the drop down selector to the one with a flat curve (beats studio I think) -- the volume for my headphones was not an issue so I defeat the EQ for better sound quality.
Whew. I Didn't think it was this complicated when I started typing....
Hope everyone enjoys better sound with this.

Loudness Equalization – and the LOW Sound Result
I was testing the system sound… CD playing in the background: Sting “If on a Winter’s Night” 02 Soul Cake playing through iTunes – standard speakers-headphones (beats-audio coasting along).
Sounds -> Playback Devices -> Speakers and Headphones -> Properties -> Enhancements
I have rewritten this part three times trying to get it right. Here’s the gist:
I switched on the “Loudness Equalization” enhancement. The sound jumped; it was loud and distorted. I switched the enhancement off – the sound dropped off and didn’t come back. I turned up the volume (with the slider) and down and up and down – and I was hearing Less and less sound from the speakers: “Low Sound Syndrome”: I was hearing what would be expected at setting of 7%. Well, that sucks. (Technical term.)
Based on this experience, I hypothesize that it’s possible to lose one’s sound entirely just by initially adjusting this one enhancement and then losing control over the ensuing ever diminishing returns. I didn’t continue to test this into a theory. It’s a hypothesis. If I had an extra dv7 sitting around, I might sacrifice it on such testing. I gave up right away and went into recovery mode while I still had some sound.
Recovery:
After the Loudness Equalization was turned off,
Recovery Attempts to recover normal sound levels included:
Resetting all Sound to Default settings,
Installing the driver from the webpage (standard load – download, double-click and install), reboot,
“Hard Reset”.
It was finally necessary to force load the IDT HD driver to recover the sound to its normal levels; that is, the driver was Uninstalled and allowed to reinstall at boot. (“Local” install from the Device Manager also works.)
Commentary:
I did not bother with a registry cleaning at this point - it may have made a difference, though it's unlikely since the driver needed to be completely reset by this time. I advocate registry cleaning! Bad things happen to good computers because of a dirty registry. Use your favorite or download CCleaner (free).
Try a Driver Update:
You can always check for Driver updates here – If the driver does update - you may be done with this part. Check the sound and proceed to "Enhancements".
At the Right-Click > Update Driver Software
Audio Driver “Uninstall”
Control Panel -> Device Manager -> Sound, video and game controllers
          Right-Click IDT High Definition Audio CODEC -> Uninstall
You have a choice at this point
If you do not have the means to replace your driver,
THEN do not delete your driver from the computer
OR - If you believe the driver is not working at all,
And / Or you have tried the standard Uninstall/self-install method previously without results,
AND You have the means to REINSTALL that driver from scratch*
Then you may delete the driver -
*Driver Installation From Scratch Requires the following:
You have your IDT HD driver on your computer as a sp*.exe file, for example, in Downloads
Reinstall with Boot:
Shut down the system
Reboot
The driver may install itself at login as the system scans for hardware changes
OR
Reinstall WITHOUT BOOT - Initiate the scan for hardware changes:
Right-Click on the IDT driver , > "Scan for Hardware Changes"
--> Check your sound at this point. It's possible that the driver has in reinstalled itself.
Manual Driver Installation - Comments:
There are a couple of paths used to get the IDT driver onto your system. You can download it from your HP Software and Driver website. You may have been given the path to your IDT driver at the HP ftp softpaq site. The package is downloaded as a sp*.exe file.   You may download the software as often as you need it. Make sure you have the package downloaded before you delete your driver.
Once you have downloaded that package onto your system, the original sp* file will stay intact. As long as you do not delete it, you can reuse it. Once you do install the driver onto your system, an installation directory is created in C:\SWSetup, named the same as the sp* file (without the .exe extension).
In C:\SWSetup\sp* are all the files necessary to reinstall your driver. If you install the software from the sp*.exe file in your Downloads folder, the new installation will ask you whether to overwrite the data in the SWSetup/sp* with the contents of the .exe package – do it. The reinstallation is just unwrapping and redistributing what’s in the .exe file into the same SWSetup/sp folder.
If the "Driver Store" is removed, that is, if the driver package is ever removed from C:\SWSetup, you can reinstall from the sp* file as long you you have it in your Downloads folder - it will recreate that SWSetup/sp* folder.
What about Versions?
Latest is Usually best. If you are concerned AND you think you may not be able to get another a copy of an older driver that is in C:\SWSetup\sp*, make a copy of the folder before uninstalling any driver or making any changes.
Installation from the Original sp* package
Find the sp* file on your system. It will be most likely be located in your “Downloads” folder.
Simple Driver Installation from the 'Saved' installation sp* file:
Close everything that isn’t needed, browsers, games, windows…
Right-Click on the installation package (the sp* file), Select 'Run as Administrator' and start the installation
Answer any questions…and follow the instructions
or...
Installation from the Device Manager
If the driver software is still on the system from a previous installation, it is located in C:\SWSetup
You can tell the Device Manager to access the package on the system:
Control Panel > icons > Device Manager > (Highlight) IDT High Definition Audio CODEC >
                      Right-Click > Update Driver Software > Browse my computer for driver software
                      Browse to C:\SWSetup\sp*
                      Be sure the “Include Subfolders” box is CHECKED
27-Nov-2011
Audio Services Check / Restart
This section is not strictly part of the "Enhancement" procedure. It has been included because it is necessary that these settings be correct so that the sound can function properly. If you are not having sound issues, skip this part...
Check system Services to make sure that your sound related services are running as they should.
Restart each service (except as noted): Right-Click > Restart
Control Panel -> icon -> Administrative Tools -> Services > bottom of page > Standard (optional - makes it easier to column sizes)
Sound services must be showing as
Status = Started
Startup Type = Automatic
Sound Services:
Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder
Power (check only)
RPC (check only)
That’s it.
It’s a matter of tweaking the settings to get results. Do not forget that that Left/Right Speakers setting is turned off in Speakers Configure. It’s not a big deal (assuming this works), but it’s DIFFERENT and it needs to be kept track of.
I hope this helps your sound work better!
Kudos are Earned!
Kind Regards,

Nice extensive research on reseting Beats Audio on the HP laptops.
Just bought the Envy 17t-3000 and I updated all the drivers via HP Support Manager.
BEFORE the update, the Beats Audio worked well..
1. Press the dial and the popup box comes up ~3 secs
2. Volume indicator swirl appeared to show volume level
AFTER the update, something changed the Beats Audio... had to re-install the latest driver from HP website (even after contacting HP Tech support via chat and email several times)...
1. Press the dial and the popup box comes up ~10-12 secs now!
2. Volume indicator swirl DISAPPEARED so volume level indicator is GONE
Sure the sound works but NOW I do NOT know or remember the volume level whenever I listen to music.
You can barely tell on the Windows Speaker icon on Icon bar since 2 sound waves indicate at least 50% sound level but that's it!
I have the following softwares and checked their settings and set them all at 50% and use the Beats Audio dial to control the volume whenever the programs are used:
1. WinAmp
2. VLC player
3. MPC
4. WMP
No matter what I try, it appears that the Beats Audio Volume Control Swirl Indicator is GONE! Worse, there's NO Windows volume control indicator unless leave the Volume Mixer open!
Anyone know how to fix this problem and bring Back the Audio Beats volume indicator??
Thanks!

HS-950 Buzz noise on CPU activity.

Hey there,
I just bought the HS-950 USB headphones, and I am trying to get them to work on my Windows 7 x64 system. I installed the beta Win7 drivers, yet I still get noise in the headphones on CPU / computer activity (opening directories, scrolling web pages). This sometimes stops, but comes back when I launch an application that uses the microphone (like Skype, Steam, or even the system sound preferences on the Input pane).
Is there anythign that can be done about it?
My system is clean, I have removed all previous drivers, and Device Manager shows that the headphones are running via driver version 1.0.0.640, from Creative, not the built-in Microsoft USB Audio drivers or the old .450 that came on the install CD.

I have exactly the same problem on my HS-1000 USB headphone.
Initially I had Vista 32bit, but I had bought Windows 7 for a different pc but decided I would install it on my current PC(64 bit installation).
Yet the problem still persists.
Also tried the headphones on a Windows XP system and same problem.
Now I live in an old house that doesn't have "grounded" electricity so I tried them on a laptop and same problem persists. To be even more sure I went to a friends house that's grounded and same problem again!
Why did I try this ground thingy, well my guitar amplifyer makes a buzz noise as well when I don't put a copper cable between it and my radiator ( e.g. ground it )
Anyway, to SeregB, I would suggest you contact the store as soon as you possibly can and send it on RMA and try and get a replacement because it seems Creative doesn't know (or want to know) what the problem is.

Beats Audio - Is it abnormal?

Hey guyz, i just bought a HP pavilion dv7-6020ev with beats audio sound system.
Well, in some songs the front speakers tend to do an annoying "shhh" noise(like high frequency distortion).Is that normal?Is it cause of the beats audio overdrive?Or it's a malfunction of the speakers?
Thank you!

i may be able to help you if you give me your laptops full name and product number

Beats Audio problem making audio quality terrible

I have a dv7 notebook with beats audio, and earlier today I was watching a movie and stretched for something on my desktop an must have hit a button on the keyboard or something because all of the sudden the Beats Audio logo comes up and the sound quality changes, to what seemed like mono instead of stereo. Now all the sounds on YouTube videos, movies and so on is very crappy, for the lack of a better word. It seems like it peeks and makes it all muffled very easily and it is very annoying. I found that the fn+b shortcut comes up, but it doesn't seem to do any difference. I tried restarting my computer and now Beats audio isn't even opening up, and I can't change settings in the beats audio control panel, and now when I change the volume, instead of the normal Beats Audio record icon coming up, it just shows a speaker. I guess that has something to do with beats not being on.
I really need help with this since I am unable to contact HP Costumer Support for some reason. The sound on my laptop is now awful and I need to know why Beats isn't starting up along with the computer anymore, and why, even when beats was working, it changed the audio. Please help me.
Thanks!

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp55001-55500/sp55094.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, restart the notebook and let Windows fully load. Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button.
Has this made any difference?
Regards,
