IMac Sound Issues.

Right this has happened a couple of times now, its completely baffling me.
I'm mid way through using my mac as usual and randomly (most of the time while using skype) my sound will just stop.
Everything is playing etc on my itunes & tic'ing over fine.
I have no input for mic or speakers in.
The setting via system preferences are all normal and volume levels are fine aswell as balance.
I press the volume keys on keyboard -- all working fine.. just nothing comes out..
When i restart it works again..?
Why does it do this & can i fix it?
Thanks, Max.

Try both of these actions and reboot. Usually fixes it!

IMac Sound Issue

Hi All,
I hope someone can help me with this somewhat annoying problem. Whenever I used Ventrilo, Mumble or Teamspeak my outbound (microphone) sound goes fuzzy / whitenoise like every sort of 30 mins or so (times not exact). This is confirmed by all members on the voice comms servers at the time.
After a minute or so the sound will go back perfect again.
I have the 27" IMac running the latest update of Snow Leopard with the Intel i7.
What could this be? Is there a way to uninstall / reinstall drivers on a Mac?
Hope someone can help my otherwise perfect Mac soon
Gav

Does anyone have any suggestions
I am using a Trust headset which was designed for Mac BTW.

Having sound issues with Mid 2011 iMac 27"

Having sound issues with Mid 2011 iMac 27". It has 10.10.2 OS X. Could this the issue and if so how do I revert to 10.7.3

It is almost impossible to diagnose sounds over the internet, however here is a link to some failing HD sounds. If one of yours be happy, at any rate take it in for service. If you got AppleCare or it's less than a year old it's covered.

Imac sound problem

Approx 6 months ago started having sound issues with imac which is set up as a media center. The imac output is connected to an AV receiver via optic cable. The problem is no sound on imac programs safari, itunes etc when starting from sleep if a program is left open prior to going to sleep. Movies have picture but no sound, itunes has no sound and does not start playing the song. Quit open programs and restart computer or put to sleep and wake the sound is restored. Eye tv sound is not affected. If programs except eye tv are quit prior to going to sleep there are no issues on start up. Disconnect the AV receiver and the problem still exists?????????????

Thanks for the info, below are the results.
Started computer from sleep no sound on system. Checked Audio Midi System as suggested Audio Default and System set to Unknown Device. Reset both to Built in Output and checked sound still no go. Force quit itunes and put to sleep and reactivate sound all good Audio Default and System remained in Built in Output. Watched recording through Eye TV for about an hour then checked sound through itunes, no go. The Audio Default and System had both reverted to Unknown Device yet the Eye TV sound was not affected???????
Quit all programs last night except Eye TV and let mac go to sleep. Checked this morning sound is fine. It appears that when itunes, safari etc is open and not use for a period the Audio Default and System reverts Built in Output to Unknown Device.
BDAqua it looks like your longshot has identified where the issue is occuring and thank you. The next stage is determining why and how to fix the issue................appreciate you comments.
Cheers

My iMac sounds terrible! There's like a loud fan or motor running?

Hello,
My iMac sounds like a plane taking off! I will have to confirm what version of OS I am running but does anyone else have this issue? Is it the fan or is it a hardware issue? It has become a little slower over the last couple of months and it's only 8 months old!
Please help!

Problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset:
Resetting the System Management Controller (SMC)
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

Pair of sound issues

I have two very weird and frustrating problems regarding sound on my iMac G5.
First, certain Flash content will not generate sound at all. The computer has no problem playing sound from movies embedded in websites or mp3s, etc but for some reason embedded Flash content will not play sound. This problem has cropped up before and then went away and seems to have returned. Several uninstalls and reinstalls of both Flash and Shockwave have proven fruitless. No sound is produced whether speakers are plugged in or not. So it seems to be a software issue. My PowerBook with 10.4.2 handles the content without issue.
Second, the optical portion of my audio-out port seems to be shot. For a while I was successfully using a miniTOSLink adapter to connect some Klipsch ProMedia speakers to my iMac. One day they decided to emit nothing but a loud and annoying static when connected via optical. Connection via analog headphone jack yields normal operation (barring the above problem with Flash).
And of course my 90 days was up in June.

I too have had sound issues. I haven't tried the flash and shockwave things you have. I basically don't use them. I have had sound problems with the headphone jack/optical audio out port. I have had my G5 iMac 20" about 1 week and right from the start the sound would jump from external speakers to internal speakers. Most of the time the sound comes from the internal speakers. I opened System Preferences/Sound and I can watch the output jump back and forth between internal and line out. I called Apple Support and they got me to zap the PRAM and reset the Open Firmware. It didn't help. They told me it looks like a short in the port and to take it in to a authorized dealer for repair. Before I do that I have ordered a Xpress Digital Optical Cable from Griffin Technologies hoping this can solve the problem because you and others here have said Digital Optical cables help. There is another thread here about external speakers not recognized and one person says what worked was a combination of digital optical cable and certain adapters. I do have sound from my externals though because I happen to have a iMic. It is an external sound card that connects from USB. That is working fine. I would like to have the digital optical output though.

HP Envy 4-1215dx Sound Issues

Hi, I own an HP Envy 4-1215dx. It's a great unit overall, but I am having problems with the audio on it. From the day I took it out of the box it will randomly spew out quick bursts of buzzing/crackling/digital noise whenever I try and play some sort of media, it will appear to have stopped for a while but then start doing it again, it is quite intermitten. It does it with sound from the internet such as youtube, playing MP3's, and even in Games. It is extremely irritating and I need to find a solution. I have already uninstalled and reinstalled the audio drivers and have had no luck. Doing a quick google search, I found out that there are several other people with the same problem, yet the only answer they get back is to reinstall the drivers. I have done this already and it does not fix the problem. Any help would be appreciated.
Thanks!

Hello Livingedge,
I understand that the driver is an older version. This is the version that is available for your specific product on the HP Driver & Software page. I have been able to locate a driver that is also IDT, but the release date is 2013-09-30. I have included that driver here for you 'IDT High-Definition (HD) Audio Driver'.
If this driver fails to resolve the sound issue, I would keep an eye on the 'HP Driver & Software' page. This is where if and any updates are available, will be provided here.
Thank you.

Strange sound issue on iPad2

my mom is having odd sound issues on her iPad 2 that i was able to somewhat fix. and it goes from fixed back to broken o.O
i thought it was interesting and worth mentioning, in case this happens to anyone else.
her iPad 2 is up to date on the latest iOS (5.0.1) and the issue occured while she was watching a video in YouTube. sound is totally off in all apps. in Settings>General under 'use side switch to' it is set to 'mute'. when going to Settings>General>Sounds the volume control for ringers will work and cause the ringtone to play, so it seems the speaker itself is fine. however it will only work there and for that short time. afterward sound will continue to remain off. the volume control on the side of the unit will bring up the on screen speaker icon, except it doesnt show the bar that usually goes up and down with the volume. and sometimes at the top of the grey box it will say 'sound effects'. ive also tried switching the mute on and off which changes nothing.
the one thing ive found that changes anything is the multi tasking bar volume control (double clicking the home button and then sliding all the way to the left, where it shows a screen orientation lock, brightness slider and a volume control bar). now the volume control bar is unfilled and doesnt show the dot that you can slide up and down to change the volume. however when i plug the iPad 2 into a computer (any computer seems to cause this) the volume control bar will suddenly fill and the dot will appear. now suddenly sound works in all apps and will change with the side control again as normal.
now heres where it gets even weirder!!!
sometimes when unplugging the iPad 2, after a short while volume will slowly fade out and be unresponsive again. the side buttons stop working and the volume control in the multi tasking bar will be unfilled and unresponsive. repeatedly plugging it in, going back to the multi tasking bar volume control and unplugging will eventually bring volume back. a couple times ive gotten volume to stay on and the volume bar to stay responsive by unplugging it while im in the multi tasking bar. but sometimes this is not the case.
for the record, ive tried 'turning it off and on again' and resetting all settings and erasing all content and settings (both with starting up from a back up on iCloud and PC, and starting up as a new iPad). ive used two different laptops, one with Windows Vista and one with Windows 7. the iPad is synced with one laptop but aside from using iTunes to back it up and for charging, ive not made any changes to the iPad using these devices. during the entire duration of my attempts to fix it, the iPad has been on no lower than 80% power. ive also called Apple and discussed this with an Apple Care representative. who suggested all the same things id already done, and walked me through all the fixes to make sure i didnt skip anything.
hopefully and most probable is that its just an issue with iOS 5.0.1. i also have an iPad 2 thats up to date with 5.0.1 and ive not had this issue, YET.
i just thought it would be beneficial to the community to share this issue and get word out that this is happening. i would like to hear everyones thoughts on this issue and if this has happened to anyone else. the Apple Representative that i spoke to had not heard of or had to deal with this issue so it sounds like its rather new or rare. though she did mention that this is not normal behavior for the device and might be a software issue.
id like to conclude with my love for Apple, and how user friendly iDevices are in general. ive had iPods from the very first generation and all of them still work (though the older ones cant be updated past a certain iOS). the few issues ive ever had were easily fixed with a visit to the Apple Store or searching on the Apple Support Communities. so as with before, i will remain positive and look forward to a bug fix in the next update.
-thanks in advanced for reading, and any comments

Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Sound issue on iphone 4 - 7.1.1

My mom has an iphone 4 that was handed down to her from my sister. After one of the ios updates...can't remember which one...the phone stopped giving audible notifications for text messages. As I have tried to troubleshoot this issue I have discovered the other following problems:
The phone will not play music on any speaker. I was trying to connect the phone via bluetooth to a speaker bar and when I tried to play pandora, I got nothing. I then disconnected the bluetooth to see if I would get sound out of the phone's speaker and got nothing. I attempted to play a downloaded song and got nothing.
I then tried to see if I could find other issues and I did. When I go into settings>sounds>ringtones I can switch ringtones and hear the ringtone sample. When I go into settings>sounds>text tone, I can select any tone in the list and all I get is a vibration, no sound at all from any of them.
I also found that when pressing the volume up and down buttons on the side of the phone do not produce the pop up box that shows volume going up and down
I believe these three problems to be related as some kind of systematic software bug. Can anyone confirm this or offer a possible solution. Keep in mind the phone does make sounds when someone calls also from the speaker phone. The only non-sound issues are text notifications and playing music. I find this to be a rather important problem because the phone can really no longer be used as a phone since my mom continually misses text messages because she does not get an audible notification.

Windows Vista major sound issues

On my 2 month old Unibody Macbook, I'm experiencing severe sound issues with bootcamp 2.1 in windows vista. While playing games such as Halo 2 or Fallout 3, which the macbook graphically handles exceptionally well for a laptop, the sound crackles and often disappears! To get the sound back I have to reboot my macbook. Help, this is extremely annoying, and apple won't do a thing about it!!! Please help!

Sound issues with MacBook Pro

I am experiencing sound issues with my MacBook Pro. I am using a headset and when I am on a skype calsl I have a hard time hearing the other person, the sound is coming in and out and sounds digitized. This issue only started recently, the sound had been working fine for years before this issue.

I do not use Skype, but may be information from the below linked article helpful.

Sound issues in iOS6

I'm having random sound issues since upgrading iPhone to iOS6. For instance, after using iMessage I will sleep the phone without exiting iMessage. 5 mins later I will have messages sent to me but there were no sound notifications indicating such. Only if I exit iMessage prior to sleeping the phone will I hear notifications of new texts or iMessages. Also, random sounds like the swoosh when sending an email will mute randomly. I have to shut the phone off and restart before it works again. Why is this happening?

If you have a iMessage open and into a message, normally it will not sound. I think it is because you already have it open and in it. That is what I have noticed.

What is a packet problem? I'm having sound issues.

I'm at my wit's end. I am having sound issues. I've run diagnostic tests and everything comes back as OK, but it's not OK! Something somewhere is messed up and I can't figure it out.
I have been to the help rooms on paltlak and opened up support tickets and everything they told me to try has not helped. They suggested I change the sound tuning on my chat program, change exceptions on my firewall, uninstall and reinstall chat program, uninstall and install earlier version, download drivers for sound card, and etc. Nothing is helping this problem.
Someone mentioned that it may be router problems or packet problems. I'm not sure what that means, and that is why I'm on this forum asking for help. I have no other sound problems on my computer. My music and videos play fine. It's just when I'm in a voice enabled chat, do I experience these problems, or if I'm on a website that has videos, the video will not load all the way, so I only get 30 seconds of a video. Does anyone know what could be causing this?
I have used this chat service for over 5 years and up until a week or so ago, it worked fine. I did a complete reformat of my computer in hopes that it would help, but I'm still having the same problems. I lose sound within 5 seconds of entering the chat room. Then it takes between 3-5 minutes before I hear sound again, but then I only hear it for a few seconds. Then it goes away for another few minutes. Repeat. Over and over again.
I'm running Windows Vista on an Acer Aspire 380 with wireless cable modem. I keep losing sound in any voice/sound enabled chat and on any site that has videos. I have 1gig of ram, 300 gb hard drive, 32 bit operating system, 2 processor cores, directx version 9, realtek sound card. Everything is up to date, and firmware is up to date. My speed test is: download: 6.162 mbps and upload: 926 kbps.
When I do the ipconfig/all, it shows
Tunnel adapter local aera connection* 6: Media State: Media disconnected
description: teredo tunneling pseudo-interface
dhcp enabled: no
autoconfiguration enabled: yes
I don't know if this has anything to do with my sound issues on the chat program or not. ??
Also shows:
node type: hybrid
dhcp enabled: yes
autoconfiguration enabled: yes
default gateway: 192.168.1.1
dhcp server: 192.168.1.1
netbios over tcpip: enabled
If by chance it is a packet problem, how do I fix that?

Hi. Thanks for the quick reply. Yes, it just started recently and after not being able to fix the problem, I completely reformatted my computer and started with a fresh slate, but still having the same problems. The videos will not continue to load. They get less than half way and then just totally stop loading, therefore I only get to view the video up to the point where it stops loading. I just took your advice and I disconnected the router and connected my computer directly to the modem and my sound issues were fixed. I went into the voice chat and had sound for over 10 minutes (and then I disconnected) instead of the usual 5 seconds that it'd been. So is it the linksys that is causing this? If so, how can I fix it? Thank-you. Message Edited by nightrider7000 on 01-22-2008 11:34 AM

I am having sound issues with Pottermore while using Safari 6.1. I once muted the sound and now can't unmute it even though the icon tells me it's unmated. I can hear samples of audio books in the store section. Any ideas?
