ITunes 11.1.3 no sound output

However, VLC and Quick Time Player both produce sound. I have reinstalled iTunes and the problem persists. Any suggestions?

Fixed. Solution, iTunes Airplay was selected for Apple TV and not Computer. While the ATV is in a different room, I noticed that it was awake -- it should not have been awake -- that is when I realized that my MBP's iTunes was connecting to ATV and not playing via my local system...
Ha, So happy for a simple solution.

CPU load / sound output

today i noticed that the cpu load goes up to 15% from 2% (in itunes) when i switch the sound output from line out to the integrated speakers! can anyone confirm this? this seems to be a systemwide issue because it happens with QT and VLC (mp3 playback only) too!

I've tried it, nothing. Everything stays @2-3% while switching back and forth. So it doesn't seem like it makes a difference. I have noticed though, the CPU sitting around 40% for a few minutes without having applications open, especially after I wake the computer from sleep.
Also, I'm assuming you're using OS X, and this is where I tried this.

Sound output to Airport Express horrible except through iTunes Airplay

I've had an Airport Express for 2 or so months now, and I use it for both wifi routing as well as its Airplay functionality, wired into my stereo. I've used it with Airplay directly from iTunes as well as setting the system sound output on my Mac to go over to the Airport Express.
As of today, only the Airplay over iTunes works without issue. When I go to the system sound preferences and select the Airport Express, I hear a very loud pop, and all output is muffled and highly distorted. If iTunes is playing, that sounds bad too. However, with the system sound prefs set to internal speakers and ONLY iTunes set to Airplay, it sounds fine. This is not good at all for me, as I often send audio from Youtube and other streaming sites to Airport Express to play on my stereo.
How can I get sound output to Airport Express from the sound preferences to play nice again?
PS, I have the identical issue with Apple TV, though I don't use it regularly for Airplay. System output to Apple TV is terrible, iTunes Airplay to it is fine, and the audio from content on Apple TV is fine.

Is there any way to output any sound from a computer to Airport Express, not just iTunes?
Yes, check out Rogue Amoeba's AirFoil.

Sound output turning off in iTunes

When using iTunes on my macbook pro and connecting to AV amplifier with miniDVI-HDMI cable, the sound output turns off after some minutes. apron touching the trackpad, the sound turns on again.this does not happen with VLC. any help?

Since asking the question, I have established the following:
The sound output stops when the display goes to sleep. Note that only the display sleep mode affects this, not the computer sleep mode. Also the screen saver does not have any affect.
So, does anyone know how to stop this from happening? It does not make sense to me that iTunes ouput should stop when the display (not the computer) goes to sleep ...

Sound output plugin for iTunes?

My three year old Airport Express with Airtunes is broke. It' smells burned when I smell by the ethernet port. So, no more iTunes output to my HiFi system with the Airport Express
Now my HiFi system is connected via the Line-out sound output. The system sounds and for example Youtube movies now also playing into HiFi.
I want to know if there is an plugin for iTunes to redirect sound to an different sound port on my Mac Pro. System sounds to headphones or internal speakers and iTunes to Line-out (HiFi). Is this possible? With system prefs (10.5.1) you only can choose one output for all sound.
Is there an plugin for iTunes to redirect sound output?

I have tried Rogue Amoeba's Airfoil but this program is meant to redirect all kind off sounds to one or more AirPort Express.
I don't have an AirPort Express anymore so I want to redirect sounds from iTunes to line-out and I want system sounds to internal speakers or headphones.

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

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.

Freezing with iTunes 7.6.1, thumping sound,especially during video playback

Hi,
Has anyone noticed a decrease in system reliability after upgrading to iTunes 7.6.1, especially during video/videopodcast playback in iTunes on their MacBook Pro's?
Specifically, the entire system locks up. Reminds me of the days of OS 7.5.5 when the mouse cursor freezes, keyboard stops responding. The only way to proceed is by holding down the power button.
This has occurred about 4 times now. The trackpad will become unresponsive, keyboard buttons such as caplocks and nu lock will be unresponsive too. Most interesting is that the sound output will loop, usually a short bit of the last audio played back over iTunes.
Videos which have triggered this:
- Podcast: Diggnation
- Podcast: ABC World News Now
- YouTube video's converted by Tooble
Here's a video I recorded showing the thumping noise. It sounds like the last audio dump before the crash looped. It's not coming from the hard drive. Definitely from the speakers.
http://www.youtube.com/watch?v=wzOCcINoClg
In the video you see I had World of Warcraft up, but I don't think it is the problem, because this kind of crash has occurred while using other programs.
Details:
iTunes 7.6.1
QuickTime 7.4.1
Mac OS X 10.4.11
2.2 Ghz (MacBookPro3,1)
4GB RAM
External second monitor attached: eMachines 15" LCD
Prefrence panes additions: Application Enhancer, Divx, FinderPop, Flip4Mac WMV, Perian, Teleport, WindowShade X.
Have NOT installed Security Update 2008-001 OR AirPort Utility 5.3.1 pending user problem reports.
I never had such a complete system freeze until about the time I updated to iTunes 7.6.1. Repaired disk, permissions, cleaned up virtual memory, cache's using AppleJack.
Thanks, just want to see if this is an isolated problem.

First, create a new user account and see if you can replicate the problem on that account.
If so, start by killing all the running daemons that aren't OS X-native apps. In other words, Window Shade X, Application Enhancer, divx, etc. Quit all that junk and use Activity Monitor to make sure those apps aren't running background tasks. I'd be willing to bet that Application Enhancer is the culprit.
See if that solves the problem. If so, you can add the applications back one by one until you find the one that's causing problems.

How to change sound output?

Howdy
I recently bought a high-end toslink cable which I connected from the optical/digital out from my iMac to my receiver. The sound quality is excellent, however I noticed that all sounds now gets passed to my Hifi system all the time. The only way (I could find) to route sound to the internal speakers is by physically unplug the cable. This is really not workable in the long run as it wears down the plug and, not to mention, my patience...
So, anyone know any way to switch output to internal speakers w/o having to unplug the cable? Or is there another approach (I'm thinking Airport Express)?
/Cheers

Unfortunately, you cannot select +Internal speakers+ in System Preferences Sound pane Output tab, if you have something plugged into the audio output port.
If you got an AirPort Express, its AirTunes feature would certainly work for iTunes output. However, I believe AirTunes would only play the output of iTunes. So it would work great as long as you were only playing songs and videos using iTunes, because all other sounds will come from your computer speakers. No need to change any setting manually, after you are done listening over the stereo system. However, it would not work so great, if you wanted the audio output of some other programs to be played from the stereo system; but there seems to be a third-party solution for that issue
http://www.rogueamoeba.com/airfoil/mac/
If you have separate powered computer speakers that connect using a standard mini-jack, one alternative is to get a USB (or possibly FireWire) sound output device (if you want to be able to change the sound output setting manually). The least expensive one may be the Griffin iMic.
http://www.griffintechnology.com/products/imic/
It provides a second sound output port over USB, so it should show up as a separate choice in System Preferences Sound pane Output tab. Therefore, you should be able to use the Sound preference pane to manually switch the sound output from you stereo system to the computer speakers connected over the USB iMic.

Sound output from other user accounts

It used to be that I would hear sounds from other logged-in user accounts; I'd hear my wife's new mail arrival sound, I'd hear her Skype ringing when calls were coming in, etc. I also used to be able to play iTunes in one account, fast-user-switch to another, and the music would still play.
This has all gone away recently. I'm not exactly sure but I think it coincided with the 10.4.4 update.
This is a big concern because my wife was used to hearing her incoming Skype calls ringing when I was using the Mac, but now she misses all her calls if someone else is logged in!
I haven't found any other mention of this in any forum. Is this just me having this problem? Any way I can fix it?

Okay, I just got off the phone with Apple support and they say that sound outputting from other user accounts was a "bug" that has now been "fixed." They said that this was patched sometime between the 10.4.3 and 10.4.4 updates. I'm surprised to hear that you are having this problem in 10.4.2 because I'm sure it worked for me under 10.4.3 at some point. None of the security updates released under either 10.4.3 or 10.4.4 make any mention of this patch.
Apple support says that there's no preference for this setting and we've just got to live with it now.
This is so irritating! I've got my Skype ring tone, she's got hers, and we'd hear it ringing and know who it was for no matter who was logged in. Now that functionality is busted, and when one of us is logged in the other misses all the calls, and if one of my kids is logged in then both of us miss our calls! I can't believe Apple considers this "bug" to be "fixed".
There's got to be a way around this; maybe by using the "defaults write" command or something? That command sets a lot of preferences that Apple claims are not user-settable.

Mini Sound Output

I have a Mac Mini and I have hooked up the sound output to my JVC Home Theatre systems so I can play iTunes through it. The problem is that the sound level is very low even with all the outputs turned up to max. I need to have the JVC up to near max volume to get a reasonable sound output.
Do I need a preamp or something between the two. Any suggestions ?
Thanks

Steve,
You are correct that a phono output requires an pre-amp. However, in this case it probably is the type of connector used, a.k.a RCA plug. The mini output should be around line level (depending on the various settings for the output level) and indeed plugged into an AUX input. If a phono input was used, the sound would be very loud and distorted because phono signal levels are significant lower than line levels. I wonder if the audio input (with the mini) is selected when the original poster plays his iTunes.

How to use Airport Express as a sound output device

Guys,
Is there a way that I can use Airport Express as a sound output device? So, I can play all the sound on my HIFI.
thanks in advance

In order to listen to the non-iTunes audio streams through your Airport Express you will need to use the third party software Airfoil.

System sound output switchery

Hi everybody,
I'm having a very strange problem that I haven't figured out how to reproduce just yet but thought I'd give it a try on the forums anyway...
The problem is that the system sound output in the audio prefernce pane seems to be randomly* switching from "Digital Out" to the next one in line, my bluetooth headset. So, if my headset is turned off I get all kinds of "error connecting to bluetooth device" messages and if it's on, the battery drains quickly from connecting and disconnecting all the time. I should mention that Digital out is working beautifully; it's just that I'm getting these bluetooth errors all the time as something is switching the audio out from "Digital Out" to my headset.
*I'm sure there's a cause, but I haven't been able to put my finger on it just yet.
Sorry I can't be more specific at this time...
Cheers,
Ryan

OK, I've found that the problem only occurs when watching a movie in dolby digital (VLC or DVD Player) and a sound is played in iTunes or an event happens such as receiving an IM. This is beginning to make sense to me as the receiver after all is receiving a dolby digital signal, and wouldn't be able to play a stereo stream while it has its hands full with the dolby digital. (I guess? Correct me if I'm wrong... anyway the receiver LED can only display stereo or digital, not both at once!)
So my question becomes, how to stop OS X from directing these sounds to my bluetooth headset. There must be a way just to turn off all other sounds while I'm watching a movie in 5.1 or send them to /dev/null or something, anything other than repeatedly connecting/disconnecting with my headset or displaying annoying warning messages.

Simultaneous digital & analogue sound output

Until recently I used to have a Powermac G5. I was able to have simultaneous sound output to the line out and digital sockets, but I find in my new Mac Pro (early 2008) this does not seem possible - you have to choose between internal speaker, line out or digital.
Although not a big deal, this is really irritating, as I have my main output as digital, where I play my music from iTunes on my HiFi via a 20m Toslink cable to a high End DAC connected to my amplifier, but when I want to use iChat etc, I just use my JBL Creature speakers. With the G5 I would just switch on the HiFi only when listening to music, but now I have to remember to go to the sound preferences to change the output from line out to digital when listening to music and vice versa when I want to do an iChat.
I'm just struggling to understand why this basic functionality was removed in the Mac Pro.

With an MIO card, this is not something that you will be able to do with a 10 KHz output rate. The way to accomplish this is to generate your analog output using your MIO card, and the digital signal with a PCI-6533 connected to the MIO card via the RTSI bus. The RTSI bus allows the cards to trigger together, and generate synchronous digital and analog output
