Sudden loss of sound

I was using my macbook (white 13") the other night to do a presentation with video. I had a hard time getting sound to play, but finally did. Now I have no sound at all. The sound indicator is light gray in color as opposed to black and if I using the sounds volume keys F10, F11, F12 it shows the little circle with a line through it.
HELP PLEASE!

Try a reset of the device (hold the power and home keys down until the Apple logo appears).

MuVo TX Sudden loss in sound quality -irrecoverab

My MuVo Tx simply stopped working as usual. I was listening to it, put it away on the shelf i keep it decided to go out for a walk later on picked it up turned it on and nowit sounds as though it's only playing higher pitched notes and background vocals - almost like a recording error - for example like i was recording one channel on a 2 channel program, so only hearing half the original.
Yet using the same program Creative Media Source and even Windows Media Player 0 and on different computers incase it was my USB ports acting up.
Change of batteries doesn't resolve anything, a format via Windows in the FAT format resolves nothing. I even flashed the players bios to see if i could just everything.
No dice.
Has anyone else had this problem at all? I guess my last resort is to RMA it (if i can find my purchase receipt - why o why do i not keep better track of them).
I'm at a total loss to explain it. Oh btw the headphones work fine on my cd walkman, tape walkman and other headphones give me the same result. No physical damge noticeable, i can't recall even ever knocking it about other than to slide it in and out of a USB slot.
Any ideas appreciated.
Thanks

Problem fixed... I downloaded iTunes and reinstalled it... Alls well again

Loss of Sound HP Pavillion Entertainment Laptop DV6820ea

Hi,
Operating System:  Windows Vista
Sound Driver :         Conextant High Definition Smart Audio 221 (SPDIF INTERFACE)
Other Programmes: I Tunes
Problem :     Sudden loss of sound, I have tried the obvious such as is the touch sensitive mute switched off and the volumes switched on . I did briefly have my i-touch connected via USB but don't remember doing anything other than connecting and disconnecting the USB cable. Then there was no sound. I have also tried via control panel testing the devices and the speaker test works correctly but other than this I am unable to get any sound from the laptop. I did find, although I can't remember where, next to a I-tunes file name yellow triangles but was unabe to delete. This will probably be a very obvious and simple solution! but I would greatly appreciate any help!    many thanks

This often occurs when you plug in an HDMI device, on my machine. Try manually setting the playback device:
Right-click the speaker icon in the taskbar.
Select Playback Devices.
Right-click the audio device you want (i.e. Speakers)
Select Set as default device.
If this does not work, try logging in with an account that has administrative access. I discovered the wireless network can not be enabled by a non-administrative account, when it is disabled while logged in as an administrator. You have to go back to the admin account, enable wireless, and then log back to the other account.
Avoid updating your driver, unless the device no longer functions.

Loss of sound on imac

I have a sudden loss of sound coming from my external speakers. I can only get it back if I re boot. This usually happens every day with no rhyme or reason.
The internal speakers are ok. I use the Bose companion 5 series speakers. It cannot be the Bose because if I re boot everything is ok for a while. any Ideas?

I have been there and done that.....makes no difference. Why do you think that the all of a sudden it would change the output in the first place? Things don't change by themselves for no apparent reason. It was still on the bose speakers when I went into sys pref. Amazing that you think that it would change itself everyday....did you really read my post or were you distracted?

Loss Of Sound Sync - FC7

Hi Gang
Working with FC7 in Snow Leopard 10.6.8 and an older Mac Pro.
Exported a 70 minute clip and noticed loss of Sound Sync, (about mid way thru in a QT File). The clip is a mixture of assorted clips.
Divided the 70 minute clip into 3 separate exported clips which produced proper 'Synced Sound' in each clip.
This problem used to occasionally happen in FC6 - Does anyone know a fix or work-around?
Thank You
Mike

Loss of sound and video playback on ENVY X2

Every so often, more often than I would like, my HP Envy X2 loses sound and video playback capabilities; any ideas anybody? The concept of this machine is great and have had it for the past 9 months but this loss of sound and vision is so unpredictable and frustating...

Hi Brumage,
I saw your post regarding the sound and video issues and I will be happy to help. Do you get any error messages when this happens? Have noticed if it is a particular site like YouTube or program that you are using when the issue occurs or does it occur on all programs? When you restarted the Envy X2 does the issue go away?
I would start by suggesting that you make sure all updates have been installed through HP Support Assistant and Windows Update.
What operating system are you running? What is your product number?

Loss of sound (Hard-reset and restore does not work)

Hi,
I loss all sounds on my iPad 2 (currently on iOS 7.04). This is the 2nd time I have had this issue (had it with an earlier iPad) and had to replace the previous one (out of warranty period). Very frustrating as it is about the same time period after purchase. Last time, it seemed like a repeated fault with the iPad and I cannot believe I have the same issue again on a different product. It is an expensive way of having to re-buy every couple of years for no other reason.
It did not happen immediately after an update i.e. it does not appear to be "update" or iOS version-related.
Anyone got any advice please? The facts are as follows (and what I have tried).
When it happened?
I was in iMovie editing a movie when all sound went from the speaker. It continued to work with earphones plugged in, but this is now intermittent. I have no sound on the speaker at all except for when I click sounds on the menu and change the level of ringer alert (which works on the speakers). This seems to tell me that it is a software problem. I have no sound on any applications or internet video or music from iTunes. I cannot survive on the earphones as they only work for a period of time and then they fail (until I take the jack out again when it works again for a period of time before the headphones fail again).
What have I tried?
a) Numerous hard resets
b) changing the side switch's position
c) changing in general settings the side switch settings from lock rotation to mute and back again (repeatedly and in reverse to see if it makes any difference)
d) resetting all settings - this made no difference
e) erase all content and settings - interestingly at the stage when it asked me if I wanted to restore from an iCloud account, it was making sounds (the keyboard clicks - which don't make a sound irrespective of the click setting currently) i.e. appeared to have resolved the issue and as soon as I restored my iCloud back-up, the sound went again.
I would be grateful for any suggestions. This post also includes a recommendation to Apple on improving its product (relating to iCloud backups) as the ultimate solution should not be paying for a replacement for a software issue (to avoid losing all my data permanently).
My musings are that:
a) it is definitively a software issue (on account that the speakers work in certain situations only)
b) it appears to be that the software is corrupted in my iCloud back up
c) it is an issue that happens regularly and is an avoidable issue/cost to Apple's customers that needs to receive higher priority in being addressed as it is built in redundancy for a significant proportion of customers. At the very least, iCloud backups should be capable of being restored in part - is there any way this could be done so we don't lose all of our notes, media etc if the final advice is to "start again". How can it be right to lose all content because of an Apple system software issue? I am pre-guessing this will be the final advice (if I don't want to pay for a replacement iPad)?
Please help me and all those others with the same avoidable software problem.
Thank you,
Peter

This is an iPad user to user forum, so you are not addressing Apple.
Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

Why is it that my iPhone 4 suddenly lost the sound bar in music and YouTube? I am able to make phone calls, but otherwise my iPhone is silent. It says that it is playing music, but no sound is emmitted, nor am I able to change this.

Why is it that my iPhone 4 suddenly lost the sound bar in music and YouTube? I am able to make phone calls and hear everything just fine. but otherwise my iPhone is silent. It says that it is playing music, but no sound is emmitted, nor am I able to change this.

Not knowing what steps were included in "all the troubleshooting possible with Apple people," I'll suggest you give the phone a chance to reprovision your cellular account.
First turn off Wi-Fi. Then power off your phone. Hold the Sleep/Wake button until you see the power off slider. Then slide to power off. Turn the phone back on. After the phone starts watch to see if No Serive is displayed. Hopefully after 15-30 seconds that will change to the name of your cellular service provider and finally indicate LTE or 4G as well as include some dots indicating signal strength. You can then turn Wi-Fi back on.

Loss of sounds

Apparently like many Mt. Lion users I am experiencing loss of sounds, like mail arrival and send swoosh and trash emptying, when my computer awakes from sleep. Apple suggested the following fix - library/caches folder - delete folder, then hd/system/library/caches - delete folder contents only, which worked when i did it but problem returned after next reboot/sleep.
Anyone found a solution for this issue?
Thank u

Open /Applications/Utilities/Audio MIDI Setup
Select the Output device
In the bottom right set the Format at 44.1Hz 16bit and adjust the volume sliders then close.
In iTunes you can raise the Gain using the Equalizer (sadly the button has now gone from the bottom bar and is a /View item with no Keystroke)

Loss of sound during calls following updating iphone 4 with IOS5

I've recently updated my Iphone 4 with the IOS5 update. Since then I've had terrible problems with loss of sound on phonecalls. I can hear others but they cant hear me - loss of sound is patchy during a call. I've cleaned mic with a soft brush and rebooted but problem still exists. Any ideas before I restore factory settings/ and or take back to the shop?

I have a Iphone 4 and when i try to make calls, i cannot hear anything unless i put it on speaker, and sometimes if i try to turn the call volume up during a call without the speaker it almost sounds like the speaker is blown out. I just bought this phone online 2 days ago so i don't understand how that could happen.
Is anyone having this problem? I'm am totally lost with what to do other than return the phone in and see if i can get another one?
Please help!!!!!

Loss of sound in Windows XP in - requiring drivers to be re-loaded

This is a consistent problem under randem circumstances.
I suffer a complete loss of sound in Windows XP and the only resolution is to re-install the whole set of Bootcamp drivers or just the REALTEK audio drivers.
Sometimes after re-installing this still does not work.
Any experience of this and solutions?

Hello Ian and welcome to forums.
You might want to run the application 'Audio MIDI Setup' (/Applications/Utilities) and see if anything there is perhaps a mismatch with your particular audio configuration expectations...

Vist Basic & XFI, random loss of sound and World of Warcraft Hardware enabling iss

Hello.. First off want to say that prior to reinstalling Vista last week, I had no had any issues with my XFI and Vista.. Since the re-install, while running World of Warcraft and Ventrillo, I get random loss of sound. And by that, specifically I mean, the sound shuts off, and I get a constant loud hiss noise that does not stop until a reboot is performed. If I just run WoW and no Ventrillo, I dont get the random problem and the sound runs fine. It is however a highly annoying issue that requires too many reboots in evening. Getting to the point of just trying the onboard sound, which I'd certainly rather not do.
Additionally there is an option in WoW that allows for Hardware enabling, which is supposed to improve performance. When I check this box and restart the game, the box is still not checked. Not sure if this is a CL problem, but something is wrong for sure! I'm using the latest drivers that are on creativelabs.com for my Vista 32 bit system. And again, didnt have these issues prior to the fresh re-install of Vista. Before that I had stepped up the drivers all the way from Vista. Thanks for any feedback on this.

Not sure why your sound is cutting out... but as for WoW, it needs ALchemy installed to run with hardware audio enabled under Vista. I dont believe its in the list of titles included with ALchemy just yet, but adding it manually with the default options works just fine. Without doing this I believe the new sound core used in WoW will automatically detect that it cannot do hardware audio and simply uncheck the box whenever you try, where-as before it would work but still give you Software rendered sound (only instead of WoWs audio engine doing it, it was Vistas - not exactly an improvement). Incidentally, this not only improves performance but vastly improves the sound quality - especially when excessive numbers of sounds are being played. (eg Mass AoE effects on larger numbers of mobs, such as two Warlocks Hellfiring along with a Hurricane and Consecration while pulling the Ballroom - 9 mobs per group - near Moroes in Karazhan) Its possible doing this may also correct your cut-out issue, but its possible it wont. Ive been running WoW alongside Vent for months now under Vista w/ALchemy and an X-Fi and never had such a problem, but then I do also run Vent off the onboard audio so I can use a small earpiece and have voices clearly audible through game sound.

Crackling & loss of sound

2 weeks ago (just as my ipod went out of warranty) it developed crackling distortion and loss of sound. Initially thinking this was a headphone problem I tried different headphones but to no avail. Although I have had the ipod mini for 12 months I have only been regularly using it in the last 3 months. I calculate that I have had about 100 listening hours (a poor return on investment!) As I see that other people have also experienced this problem it suggests a design fault! What do I do now?

I have the same problem! It is intermittent, but extremely annoying. I first noticed it while using a Belkin adapter in my car... was convinced it was the adapter, tried another and got the same results. It now does the cracking when using the clickwheel as well as when connecting anything to the bottom of the unit. I can only use the iPod now if I hold it very carefully.. even then it sometimes does this and drops the signal. My unit is older, almost a year... but I am very disappointed, after blathering on to everyone about how great my iPod mini was for so long. Of course I am long out of warranty. Anyone have any suggestions?
