Flash sound suddenly distorted

The sound for my Flash player is suddenly mega-distorted (to
the point that I can't understand anything and my speakers sound
blown out). But the sound for all other functions (media player,
dvd player, etc.) is completely fine, so it's not the speakers.
It's not any particular website, either--I've tried Flash on
multiple websites and the sound is messed up across the board. The
playback might be slow as well, but it's hard to tell what's going
on without the sound...
Any ideas? Thanks!

UPDATE III:
OK, I figured this out. Hopefully this will help others. I
found a post on the Apple website talking about sample rate
settings in a utility called "Audio MIDI Setup" in OS X. This is
really just a more detailed sound preferences panel (so I don't
know why the h*ll they didn't just make an "advanced" mode for the
prefs panel, instead of making you seek out this special utility
that changes system settings). In it you can change the sample rate
and bit depth for sound input and output into the system. When I
opened this utility the first thing that I noticed was the system
was set up to output sound to the FW unit at 48k sample rate.
So I reasoned correctly that Flash can't output audio output
at 48k. It outputs at 44.1 k or less apparently. As soon as I set
the FW device's output sample rate to 44.1k, audio out of Flash
immediately sounded crystal clear again. The distortion was, I
suppose, system software trying to interpolate the 44.1k sound to
48k before output.
So the lesson is: pay attention to sample rate settings in
the "Audio MIDI Setup" utility. I just can't believe it took me
this long to find out that the utility exists and that the people
at PreSonus didn't know about it, or this potential issue. But
either way I'm glad I've got the Focusrite unit now and it works
swimmingly well.

MuVo V100 suddenly distorts sound output, hates vocalists

9MuVo V00 suddenly distorts sound output, hates vocalists Greetings. I have a MuVo V00, which until quite recently has worked according to specifications as desired. After a period of nonuse, upon reinstatement it showed a global distortion in sound output, resulting in--impressi'vely--vocal frequency-range portions of files to be suppressed. Never mind that some music was improved in this way--it is an error that needs rectification, and unfortunately MuVo V00 models are past the End of Service Life.
I have downloaded the firmware patcher, and reapplied the latest firmware (which I had already had on the device, but consensus in various problem threads here leads one to believe that refreshing the firmware is a borderline panacea). No good. Swapped batteries on a hunch, no good. Swapped headphones, no good. Checked the files that are actually on the disk, they sound like they ought when played through the computer's means. I'm low on ideas, and the last person who asked this question here did not receive a reply. Anything spring to mind?

Imac DV G3 (PPC) speakers suddenly distorted sound output

HI everyone, I just bought an old iMac DV running OS9, and it worked just fine for a few days then - for no reason whatsoever, the stereo speakers suddenly produce very distorted sound, even at low volume. At higher volumes you can even see the speaker cones vibrating.
When it happened, I was just installing a few things with the volume set low, and the alerts suddenly sounded very distorted and remain that way. I didn't blow the speakers by playing loud music or anything like that.
I had nothing to lose, so I reformatted/installed new system but the problem remains.
My guess is that this is an electrical/hardware problem just down to plain old age, perhaps a bad solder joint or something. It's not the end of the world but it just seems strange that it happened so abruptly I did not move or thump the computer in any way.
It's an iMac DV from 1999, given it's age I'm not expecting miracles, but just wondering if anyone else ever had a similar problem and managed to fix it without pulling the computer apart and replacing a hardware component which is way too much hassle!
Were these models' speakers ever known to suddenly crap out with no warning?? Some older macs had design flaws they became notorious for (I'm thinking of my Ti Powerbook G4 hinges, I had that once!)
Is that extra button on the side booting into open firmware of any use? Just a stab in the dark!!!!
Any ideas/insight anyone?
Thanks!!!

At higher volumes you can even see the speaker cones vibrating.
That is normal. If they don't move, they don't work.
However, it could be that someone else overloaded the speakers and caused them to fail. I think the first step is to see if the speakers have been damaged. Use a pair of external speakers or headphones and test the sound.
Failed speakers in G3 iMacs are not a wide probelm like the one you mentioned, or bad capacitors in eMacs. Generally, the failure mode is the passive cooling (read, "no cooling") system baking the PAV board until some part of it fails.

In desperate need of help! Final Cut Pro suddenly distorts audio!??

Hi
I have filmed much with my 7d using a juicedlink mixer and imported it into final cut pro.
Suddenly when I am editing the sound gets distorted and really high even though the sound waves look fine. It happens mostly in transitions on all my timelines. Here is a video clip of the phenomenon: http://enelesfilm.se/ovrigt/audiofail-desktop.m4v
Look at the audio meters Why is it like this and how do I fix it?!
Thank you so much for any help!

If you open these files with Quicktime and hit command+I QT inspector will show the info you need, however, glitches like the one you are having can often be caused either by unusual/unsuitable clip settings or corrupted preferences.
If audio is indeed AIFF 48kHz 16 bit and a re-start of the programme does not fix the issue you may want to try [trashing the preferences|http://www.digitalrebellion.com/pref_man.htm].

Sound becomes distorted after some time

I use a Creative Fatal1ty HS-1000 USB headset and after playing some time (usually after about 1 to 2 hours) the sound suddenly becomes distorted. It's hard to describe but the sound becomes metallic ,digital, sort of robotic...This is very annoying as it forces me to restart the game and I only play long MP missions online and after restart I'm forced to sit the mission out.! More often then not I continue playing 'deaf', not a solution either! It is solved when I unplug the headset and plug it back in, but then the sound in my game is completely gone!
I have searched a bit and found a post on another forum wich suggested a firmware update, tried that but got the message that newer software was already installed.
I am looking for one of two solutions;
-A complete fix, whatever this might be...
-A way to get the sound back ingame after unplugging and plugging the headset back in.
My hardware is;
Creative Fatal1ty HS-1000 USB headset
Xtreme Gamer soundcard
Windows 7 64b Ultimate

Had the same thing, its firmware related issue. Might be also drivers. Update them.
Also, i had this problem when i was at Win7 beta (the very first one). Same drivers and firmware in Vista, worked fine (still works). Make sure u got the right OS drivers.
Thisis really confusing, wich are the correct drivers and firmware? I only found these:

Sound suddenly starts and stops working?

My iPhone 4S isn't making sound. My settings have not changed and I have turned my phone on and off several times. When I click the buttons on the side to adjust, the icon shows on the screen, but the dots for volume are not there. In my music, it plays, but the sound bar is grayed out, and it won't adjust at all when I click it. In some apps, like YouTube, the sound bar is gray as well, but again, I didn't make any adjustments to my phone. I haven't dropped it. It had stopped and started working multiple times. It went in and out while I was getting ready for work this morning. I got a text alert and then the next text it vibrated but made no noise. I don't get the sound when it sends a text or the noise when it locks my phone. It's like the phone suddenly mutes itself but I didn't tell I too. My music has started and stopped as I wrote this message but again, I have done nothing to the phone itself. I assumed this was a hardware glitch because all the advise I have found for this issue is to clean out the sound docks on my phone. I did that already but the issue has persisted. Turning it on and off has not made a difference. I also can't hear calls. My phone is pretty useless without sound.

Sound suddenly stops working (Youtube)

Hi!
Since I installed a Flash Player update 1-2 months ago, the sound in almost half of the videos I watch on Youtube suddenly stops working (usually only in videos that are longer than 10 minutes). First there's a short crackling sound (not all the time, though) and then the sound simply stops, even though the video is still playing. Reloading the page or jumping ahead a few minutes, then going back to the original spot usually only fixes it for less than 5 minutes and if I do that 2 or 3 times, the sound won't even be there for more than a few seconds. Restarting Firefox doesn't help, either. If I want to try again with the same video a few days later, the problem occurs again.
I'm using headphones (Sennheiser HD 201) that are plugged into speakers (Logitech X-140) but I'm 100% sure that those aren't the culprits since I can listen to mp3s, watch videos (avi, mp4, doesn't matter) or play games just fine and the problem has never ever occured while doing that. So it definately has something to do with the update 1-2 months ago and the latest update (maybe a week ago) didn't fix it. I also already saw a few comments on videos I'm experiencing the problem with about the sound suddenly stopping.
OS: Windows 7 (64 bit)
Browser: Firefox (36.0.4) - also tried loading the video in IE11 but all the buttons (quaility settings,...) were missing, so I closed it again.
Flash Player: 17.0.0.134
Any idea how I can fix the problem and if there's already a fix in the works?

Most of the videos on YouTube these days are HTML5. If you right-click on the problem video, are you getting About Flash Player, or About HTML5?
If it *is* Flash, do you have the same problem if you disable Hardware Acceleration? See the section on it in the troubleshooting guide below:
Video playback issues

I can hear both a clean sound and distortion at the same time.

I can hear both a clean sound and distortion through my monitors and headphones. I am playing into a Presonus USB and directly into a MacBook Pro. Any idea how I can get rid of the clean sound?

You probably have a mix knob on your interface that switches between dry and wet signal. The knob should mix the signals.

No Flash Sound on YouTube

HP Pavilion Entertainment PC dv9700
Service Tag dv9910us
Window 7 Ultimate 32-bit.
Get no Flash sound on YouTube or CNN. Get good sound from YouTube videos saved to hard drive by Realplayer. Then the saved YouTube video plays everywhere: Windows Media Player, VLC and Realplayer. I recall the YouTube sound disappeared in the last weekend of Nov 2011 when Flash was automatically updated. At first it was intermittent and then silent forever.
So far. No luck. I deleted and reinstalled Adobe Flash. Even tried the Flash Uninstall Utility. Actually I deleted everything with Adobe listed on it vias Control Panel Uninstall. I deleted the sound driver for the Conexant High Definition SmartAudio 221 and reinstalled. I even unpdated it. I consecutively deleted and downloaded the latest versions of IE, FireFox & Chrome. I tried Microsoft Fix-It.
In Device Manager, there are two yellow warnings. NVIDIA nForce Networking Controller (Code 10) and USB Host Controller (Code 43). I don't know if one of these can be the issue.
One weirdo. Sound worked for 30 seconds one night the first week of March when my wife innocently started to watch YouTube. When I realized it and called it to her attention, the sound disappeared. Go figure!
I'm thinking of restoring Windows 7, but that will create a lot of work for me.
Any new information on a fix?
With so many complaints -- it seems -- everywhere, I'm surprised someone like Adobe has fixed the problem?
Naive question: Are we locked into Adobe Flash Player for YouTube or CNN?
Thanks.

Extract audio from .fls (Flash Sound Bundle File)

Greetings!
I would like to ask if it's possible to unbundle a Flash
Sound Bundle file? I've downloaded FlashLiteBundler.exe to check if
it can also unbundle, but it could not. A client wants to reuse
their audio files from a previous project, but alas, they could
only give us files of .fls format.
Any ideas on how I can go about this?
Peace!

Hi kglad!
Thanks for the reply. :)
1) The sad part is that Flash Lite 1.1 Sound Bundler only
appears as a flat square with the words "Drop Sound Files Here." A
few audio files are supported, such as .mid and you just drag the
audio onto the square, until a window appears which says, "MIDI
file __.mid added, size ___ KB" There are no other controls there
except the Delete, Clear All and Save Bundle buttons.
2) When I try dragging an existing .fls file (the one from
the client), it says "Unknown sound format, file not added."
3) When I try dragging an .fls file which I made myself using
Flash Lite 1.1 Sound Bundler (FlashLiteBunder.exe), an "OK" message
box appears, which says "1 device sound found. MIDI (___KB)". Other
than that, I can't get the Sound Bundler to do anything else.
I was wondering whether there's another way to unbundle using
another Flash tool, or maybe the bundled file is in a known format
which I can unbundle with something else? When opened in a text
editor, the .fls files from the client begin with "FWS".
Thanks.

I have the same issue. If I open up the Equalizer and select any setting (including the one that is already checkmarked), the sound corrects itself. However, it goes right back to crappy when a new song comes on.
