Sound Output Keeps Resetting

Hi,
I have speakers that are connected to my Mac Pro via line out, but the output device keeps automatically resetting to the internal speaker for some reason. Resetting the PRAM didn't work. For the record, I'm running 10.7.5. Anybody know what the problem is here? Thanks.

Sound output: keeps changing from internal speakers to Apple TV

My iMac keeps changing the soudn output from internal speakers to Apple TV. Why. This makes it a pain. Eveytime I use the iMAc, I have to go into preferences>sound>output and switch to internal speakers. Any ideas how to stop this form happeneing?
Thanks!

If you use LogMeIn, it is their sound driver. I'm having identical problem and it started after using LogMeIn.

System Sound Output Level Reset After Reboot ?

Whenever my iMac Core Duo is rebooted, system sound output level always get reset to value 0.56 (-24dB) as shown in utility "/Applications/Utilities/Audio Midi Setup". I have to increase the system sound output level to desired value of 0.75(-12.75dB) to match with built-in amplifier of Altec Lansing FX6021 speaker system. The desired setting lasts until next reboot. Is there any way I can fix the system sound output level at desired level between reboots ? Why I have to be involved in such constant struggle with the iMac for such simple audio configuration ?
Audio Hijack Pro 2.6.7 wihtout Soundflower 1.1 virtual audio device has been installed. Audio hijack function of this utility has not been used at all. Thank you for any pointer.

Thanks for the confirmation that my iMac is not an isolated case. In case you are not willing to use Audio Hijack Pro, just use Automator to create an Automator script to set system volume (In Automator's Library plane: Applications>System>Set System Volume) and save it as application. Set this application as Login Items for your account through following menu path:
System Preferences>Accounts>Login Items. Whenever you login with this account, the script will be invoked automatically by Mac OS X and sound levels for output, input and alert will be set to user preferred levels. For older versions of Mac OS X (10.3.9 and earlier) without Automator, same effect can be achieved with Apple Script, use Apple Script Editor instead of Automator to create Apple Script and set it as Login Items. This workaround has been working consistently on my iMac Intel Core Duo.

Audio Output Keeps Resetting

Fro some reason my audio setting keep resetting every time I shut my computer down. Not sure what is going on but I have to go back into System Preferences to rest them. Any thoughts?

It is a known issue. Switch is not flipping.
I would take it to an Apple Retail Store or an Apple Authorized Service Provider (AASP) for evaluation, or call your nearest Apple Contact Center. Visit the Genius Bar at the Apple Retail Store, make a reservation.

Why do my sound output settings keep resetting after restart?

Just bought a MBPro with OS 10.6.4.
After restarting my sound output settings keep resetting to Soundflower (2ch) from Internal speakers.
It doesn't take too much to change it, but it is pretty annoying and I'm assuming there's some obscure setting that can fix this.
Anyone able to help?

This fixed it on my Mac Pro. It might work on a MacBook Pro.
Delete these three files:
/Library/Preferences/com.apple.soundpref.plist
/Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist
/Library/Preferences/Audio/com.apple.audio.SystemSettings.plist
Reselect whatever sound device you want as your default in the Sound Preference Pane.
Restart the computer.

Sound output channel keeps switching by itself every few seconds

Hey guys, I have this sound output issue with my Macbook pro 2010 September version that every once in a while, the audio output would keep swapping between headphone, digital output and the speakers when NO headphone or digital output or what so ever is actually plugged in. During this time i am unable to adjust sounds, and my menu bar would become very slow to respond (the sound icon and Soundsource application would stop responding during this time). After a while (could be less than 10 minutes or last to about an hour, it varies), it returns back to normal by itself.
I've read many posts on Apple forum about this issue, but i haven't found a suitable solution. Also, I read that for most, when the audio output doesn't work it would usually be a output socket issue that there is a RED light in the socket. But for me, at times it has a RED light, at times, it doesn't, and sometimes the RED light would switch on and off by itself for a couple of times, depending on how long this issue lasts until it returns to its normal state by itself.
I have tried:
1. plugging the headphone into the socket and take it out quickly
2. Downloading Soundsource: i heard that Soundsource has an option of manually adjusting the sound output channel instead of letting the computer switch automatically, but unfortunately I downloaded the latest (2.5) version of the software and it doesn't have that option on my macbook pro.
3. I also tried Cmd + Opt + P + R
The result however is that none of this worked.
Does anyone have any suggestions?

I have both and haven't experienced this at all. Very strange. I do get a lot of random channel changes however when I put my iPad on the remote, the cat walks over it or the dog sits on it.
That being said, I don't use the Samsung remote at all for the TV and never have done. I dislike it and find it unresponsive. I use a different remote to change through the available outputs and the Vision remote for Vision and for switching the TV on and off.

My iMac sound keeps resetting to come out of left or right speaker only. Why?

I have a new iMac 5k Retina. With this purchase I also started using some speakers through the headphone jack. I've noticed this annoying pattern that quite often the sound from the iMac keeps resetting to come out of the left speaker only or the right speaker. I keep having to reset it to balance them.
Is there a way to stop this?
Thanks.

I can see my Airplay device in iTunes, but I cannot see it in Sound Output list. How to fix it?

I have Bang&Olufsen Beoplay A9 and using it with my mac air OS X 10.7.5
my problem is I can see my Airplay device in iTunes, but I cannot see it when I go to System Preferences > Sound > Output and because of that when I play a song from youtube, sound comes from my laptop. How can I fix it? thanks in advance

Hello there sjbrosjbro,
It sounds like you are not able to print to your printer because it keeps timing out when you try. I would use the troubleshooting steps from the following article to help you get that printer going again. It may be something as simple as re adding the printer if you've already restarted both the printer and the computer already:
Troubleshooting printer issues in OS X
http://support.apple.com/kb/TS3147
USB printers and Bonjour-enabled network printers
Follow these steps until the issue is addressed:
Make sure that the printer is powered on, has ink / toner, and that there are no alerts on the printer’s control panel. Note: If you cannot clear an alert on the printer's control panel, stop here and check the printer's documentation or contact the manufacturer for support.
Ensure the printer is properly connected to a USB port on the Mac or AirPort base station / Time Capsule. If the printer is a network-capable printer, make sure that it is properly connected to your home network.
Use Software Update to find and install the latest available updates. If an update is installed, see if the issue persists.
Open the Print & Scan pane or Print & Fax (Snow Leopard) pane in System Preferences.
Delete the affected printer, then add the printer again.
If the issue persists, try these additional steps:
Reset the printing system, then add the printer again.
If the issue still persists, reset the printing system again. Download and install your printer's drivers. Then, add the printer again.
Contact the printer vendor or visit their website for further assistance.
Thank you for using Apple Support Communities.
Take care,
Sterling

No sound output in Messages

I'm running 10.8.2 on a MBP 2.66 ghz Intel Core 2 Duo.
When I go into the Messages preferences, the Sound output option is greyed out, similar to the Camera.
Microphone is working fine but I can't hear anything from the other side.
If I plug in some headphones, Sound output option changes to Headphones but remains greyed out and sound still doesn't work.
I've already tried resetting the PRAM with the Option-P-R trick but that hasn't helped.
Thanks in advance for helping to fix this.

HI,
Sound in Messages needs the Output device set in System Preference > Sound > Output in the first place.
This should then show up in the Messages Menu > Preference > Video Section in the output drop down (If there is only one choice in System Preferences then it will not be a drop down but just the greyed out name of the Output.
PRAM is OPT+CMD+P+R not just Option and the letters.
If you have sound in other apps like iTunes and the volume is actually set high enough then open the Connection Doctor in Messages > Video menu.
If you do this during a Chat then the incoming Video and Audio feeds are represented by two green bars.
Having a green bar fro audio doe snot actually mean anything is being sent from the other end.
But a lack of a green bar does mean they are not sending anything.
Get them to Check:-
They has set the mic and Volume in System Preferences > Sound > Input.
The volume needs to move the blue response bar at least halfway but not bang into the right hand end.
The Same mic or input device needs to be selected in Messages > Preferences> Video Section > Microphone Drop down.
It also needs to be "On" and ticked in Messages > Video menu > "Audio chat Enabled".
(IF they are using iChat then same Menu > "Microphone Enabled")

Suddenly NO SOUND OUTPUT

Out of nowhere suddenly my relatively new iPad Air gets no sound output.
It happened without any preceding fall, trauma, new installation, or prolonged usage or signs for concern.
Troubleshooting clues so far:
-did not receive sound even when I routed through Bluetooth headphones (thus NOT a hardware issue)
-messed around with sidesswitch settings, accessibility, reset, as advised by some prior Related posts. No change.
-once or thrice when I keep trying to adjust volume and Play various test media, I am getting a LOUD horn about 500 msec approx middle-c pitch. It sounds like a noise you'd expect to come from a 1997 Windows desktop PC.
IPAD air is 16GB wifi only, running iOS 8.0 software auto updated 3 days after I took it out of the box
Has 6.1 GB free space currently.
NOt it sure what else is relevant to include.
NEED SOUND! Useless to me without that

Try a reset - hold the power and home keys down until the Apple logo appears. If that does not help, take it in for testing/diagnosis.

Can not change sound output. Help Please

Well, i've been digging all the forums lately in web. my problem is, i can't change my 'system' sound output to my sound card which is Native Instruments Audio8 Dj.
Let me explain my problem decently. I do the usual procedure, system preferences > sound > n then select the output. but nothing happens. it is always set on internal speakers or headphone or whatever plugged in to the *Built-in Output*. I try switching from audio-midi setup n that doesn't work as well. The system perfectly recognizes the sound card, i can get output from sound card with applications which have their own output settings. But i cant change the system output. I have the latest version of soundflower loaded(this might be causing the problem who knows), i used many soundcards before(or maybe even ex-drivers?) n they used to work until i updated to snow leopard. I also tried trashing the files in macintosh hd > library > preferences > audio >>
and those files *did not regenerate* after restart(like 10 times), so i had to copy them from my imac.(hehe). i tried resetting pram or nvram.(didn't do any good too)And also i tried trashing soundpref.plist which didn't do me any good neither. Now i need that sound card to give me my system output. I don't need drivers of any other ex-sound cards or whatever. My drivers are up to date. And im pretty sure this ain't an hardware fail.
So, any ideas? Thx.

I am having the exact same problem. I have spoken with Apple Care and they are having my case reviewed by "Engineers," apparently. Its very frustrating as I cannot listen to iTunes or any of my video games through my really nice monitor speakers. FYI, I had this problem without installing Sound Flower, since then I have installed it in the hopes that having something different to select it might work but no changes. If I hear any good news from Apple I will be back to let you know. This seems to be a very rare problem as I have only found one other post about this issue.

The sound output does not work on my ipod

Hi There,
I have an Ipod 4 th generation and the sound output no longer works on any device. I've reset and reinstalled the software but nothing appears to work?
Any ideas please?
Serial number: 9C6463XJV9R
Thanks Chris

If none of the 5 R's helped address the issue, it's likely hardware related.
http://www.apple.com/support/ipod/five_rs/
As to what exactly is damaged/faulty, no there is no certain way to tell. It could be the iPod's audio chip or something else on the logic board.
Either way you'll need to have your iPod serviced/replaced either by Apple or a third party company.

Help with sound output via HDMI

My sound output via HDMI suddenly stopped worked to my TV set. I've reset the PRAM and the SMC. When I go to sound control panel for sound output, the setting is on Headphones. When I try to change it to SV420XVT1A (the tv) it immediately jumps back to headphone. I also tried a different HDMI cable to a different HDMI port on the tv. This just started after the Mac Mini had been turned off for a week. I'm using Lion and it's an 8GB Intel Core 2 Duo. Any suggestions?

I actually discovered this answer about 5 minutes after I posted the question. Thanks a lot for your help!! Funny thing is that it had worked all along with something plugged in the headphone jack but suddenly stopped working. Again, thanks!

Iphone now it says it needs to be activated and plugged into itunes. It wont let me do anything because it keeps resetting. Help please.

I cant coonect it to the computer because the iphone keeps resetting itself and the restore or activation cannot be completed. Do I just need to get a new iphone? I have a 3gs and dont want to get a new iphone. Also the iphones sim card wont work and I have tried to do a hard reset mutiple times.

Sounds like your phone was jailbroken. If it was, you will need to get another phone. That phone is permanently disabled.

Assigning an application to different sound outputs

Question: Is there a way to assign an application to use a sound output options in the mixer or another Win7 application?
I have installed Win7 RC 32bit. I have headphones and speaker outputs on my system. Both are detected and both can be assigned to a working default sound choice. I am unable to assign an applications sound output to a certain outputs or change them.
The only way I can make a sound application work through the speakers if the headset is assigned the default role is to go into sound management, then assign the speakers to default and then restart my application.
Desired: I would like an application profile to default to the assigned role from the mixer. The settings could be permanent or temporary. If the 1st choice is not available, use the alternate working or (default). The sound should dynamically change or at the very least keep that profile with that application until changed.
In the mixer, I should be able to rt click on the application in the mixer and manually assign it to a sound device. This option should be assigned to a default target to play ONLY if the desired is not available. Possible options can be, just one time, or have this device handle sound if available.
Hardware: Asus Rampage 2: Gene motherboard, 6GB Ram, GTX 275 graphics, Seagate 1.5TB. Drivers auto discovered on install and appear to be functional.

Hi TKCDAC,
As you may noticed, great improvements have been made in Windows 7. Applications can realize Stream Routing via the new Core Audio APIs. Windows 7 has the ability to distinguish between communication devices and all other audio devices. It is now possible to have both a Default Communications Device that is separate from the Default Audio Device. The Default Communication Devices will be used for PC based communication like web chat or VOIP, and the Default Audio Device will be used for everything else. Stream switching enabled dynamic stream switching based on the default device. If the default audio device is disabled or unplugged, Windows automatically tries to determine the next default audio device and will dynamically redirect the audio to that new device.
For instance, if you would like to play the audio via headphone when using communication applications such as Windows Live Messenger, we can simply right click the volume icon in the system tray, click Playback Devices, right click the headphone listed and then choose Set as default Communications Device.
For more information, please refer to the following articles:
http://msdn.microsoft.com/en-us/library/dd756612(VS.85).aspx
http://louisgale.blogspot.com/2009/08/live-messenger-and-default.html
Also, based on my test, certain application such as Windows Media Player has a sound output option. To change the settings, please open Windows Media Player, click Tools, Options, click Devices tab, double click Speakers in the Devices list, pull down the Select the audio device and then choose the device you would like to play the music from Windows Media Player, click OK. We may play another song in the play list to take effect.
In the meantime, I will forward your suggestions to our Product Group. Please be assured that any improvements in the product are based on users' requirements.
Thanks,
Linda
