Output volume reset at start up

Hi Guys,
need your help.
i connect my iMac to my hi fi system, so i want to keep my iMac sound level to MAX and control my sound level at my hi fi system.
i use to have a Mac Pro and i didn't have any problem, now i switched to iMac i7, volume level always reset to 50% after each boot?
Thanks for any help.

Hi MGMM
It's a built in safety feature, so that people do not blast out there ear drums when using bud's or headphones connected to the Output Jack.
I'm not sure why you need to turn the main volume turned all the way up, ¼ to ½ should be plenty if your patching it into a decent sound (hi fi) system?

OUTPUT volume resets to high after reboot

I turn the OUTPUT volume down then shut the computer off but when I boot it up the OUTPUT volume is hi again. I have reset pram, repaired permissions and still the same.
Must be a pref bad somewhere.
There are no stuck keys on the keyboard

It may be a bug, but it obviously does not affect everyone. It does not happen on my older Intel iMac. And there is a +Early 2009+ Mac mini in the house, 2.0 GHz (same as and in Dah•veed's profile); it does not happen on it either.
When you did the test of setting volume low (or muted) with external speakers disconnected, and restarting with the external speakers disconnected, was the startup sound from the built-in speakers low (or muted), or was it already reset and loud. This will better determine when the volume reset takes place. If it's already loud, then it takes place during the previous logoff and actions that take place before restarting (or shutting down), or during the initial few seconds of startup (before the startup sound). If it's still low (or muted), then the sound volume reset takes place at some point after the startup sound, but before startup completes.
As another test, if you set the volume low, then log out and log back in (instead of restarting), does the volume stay low or does it get reset to the higher volume.
And as one more test, create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8235.html
Log out and log in to the new account. Go to System Preferences Accounts pane and set it for +Automatic login+ (If you don't use automatic login normally, then you don't need to set it). Now try doing the same test, except from this account instead of your normal account. Is there any difference in the volume setting being retained?

Volume resets to 50.

Every time I start up my Touchsmart the volume resets to 50.
I had the same problem have the same problem with screen brighness.
Any fixes?

If you use Utilities/Audio MIDI Setup to adjust the global levels for headphone output does it still reset itself ? (Because it certainly should not ... if so it would imply there's something in the Startup Items adjusting it)

Output Volume Stuck

Hello
I have not updated or changed any settings on my PowerBook, but the output volume seems to be stuck. I can not hear anything, not even start up chime. The volume icons when pressed on the key board show a circle with a slash through it. I have gone into system preferences and attempted to check there, but I can not move the slider bar for the out put volume, nor can I select the mute or unmute. How do I fix this? please help!
Thank you,
Rebecca

Welcome to the Apple discussions.
Sometimes the volume setting gets jumbled, and resetting the PRAM will fix it. Follow these steps:
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.

Output volume on my MacBook Pro is not working

My output volume on my MacBook Pro is not working. When I go to "Settings", then "Sounds", then "Output", I can not slide the volume bar at all, or change it in the menu bar?

See if a PRAM reset will solve the problem;

Output volume

I have to reset the output volume in my System Preference whenever I restart my computer because it reverts back to some default setting whenever I restart. How do I change this setting?

Thanks, your message did help and gave me a little bit more knowledge about the world of sound which is becoming more complex than I ever imagined.
But I want more volume.....
I have tried using the volume enhancer preset (hiFi) from the inserts of the output track and this has increased my volume, but my RMS is still only getting to around -14.
Any ideas on how to get more volume anyone?
And by the way, am I doing the right thing by using the output track to control my final volume output? I have found that the master volume fader on my TASCAM-428 will also define the final level of my mp3 bounces, and that they are basically interchangeable in terms of controlling output levels.
e.g. if i have everything all the way up and then pump my master volume fader on the Tascam to full, my file will distort.
Thanks in advance (hopefully).

Sound Output Volume Preference won't stick in newly reinstalled 10.6.8.

I recently re-installed OS 10.6.8 (from the retail Snow Leopard Install DVD, followed by the 10.6.8 Combo Updater) to my 2006 iMac (version 6.1) 24". Ever since, whenever I re-boot, the output volume of the internal speakers is set to a reduced level. When I bring it up to the level I like - that's fine, but only for as long as the session. If I re-boot, the level is once again dropped down to the reduced level.
I've reset the output level using the keyboard keys, and also in the System Preferences - nothing seems to stick. I've even plugged in a pair of headphones and set the output volume to be the same as my preferred speaker level, but still, nothing sticks.
I can't find a preference file to delete that is specifically for Sound Preferences. I've used Cocktail to search for a corrupted preference file, but that finds nothing as well.
How can I regain control of my volume setting so that it will survive a re-boot?

I should have added that resetting the P-Ram didn't help, neither did an SMC Reset.

Microphone.addEventListener(SampleDataEvent.SAMPLE_DATA) Causes output volume to decrease

I would like to record sound from the microphone in AIR.
This is working, except that while recording, AIR reduces the volume of all playing sounds.
This volume reduction is triggered by
microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, myFunction);
It should be noted that myFunction() can be completely empty. The output volume is still reduced.
How to reproduce:
// Start playing a sound
var url:String = "100Hz_44100Hz_16bit_30sec.mp3";
var urlRequest:URLRequest = new URLRequest(url);
var isound:Sound = new Sound();
isound.load(urlRequest);
isound.play();
// Set up the microphone
var microphone = Microphone.getMicrophone();
microphone.setUseEchoSuppression(false); // I have tried both ways.
microphone.setLoopBack(false); // I have tried both ways.
microphone.rate = 44;
// Start recording
microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, gotMicData);
// The volume of 'isound' will now be reduced until the microphone listener is removed.
// Once the listener is removed, the volume of 'isound' returns to normal.
I do NOT want the volume of other playing sounds to be reduced while recording. How might I do this?
Note: I am using Windows 7.

I believe reducing volume on mic record is a Windows 7 feature and nothing to do with Air.
To disable this, take the following steps:
Click Windows button
Choose Control Panel
Choose "Hardware and Sound"
Choose "Manage audio devices" under the "Sound" heading
Goto the "Communications" tab
Set "When windows detects communications activity" to "Do Nothing"
Even though that setting says it's supposed to adjust volume when placing telephone calls using you computer, I have had it reduce volume in some programs when i activate the microphone.
Let me know if that works for you.
Edit: Heh, was reading some other recent forum posts to see if there was anything else I could help with. The thread "2 flash instances & Windows 7" currently a few below this one on the front page mentions this Windows 7 Feature, although it's causing a different issue for him.

IMac audio output volume

got a 21.5 iMac late 2009 and noticed a huge difference in volume:
-from headphone output sound at minimum is almost harmful and definitely too loud at mid position( I'm using same cheap headset as before )
-from built-in iMac speakers volume looks normal (louder than with my g4 iMac, but never too loud).
Tried with sound prefs but the difference remains.
Is this normal ? I mean, in the new iMac the headphone output is (too) much better or there is a way to fix at the same level the two outputs ? or do I simply have a very Low volume from iMac speakers?(using headphones is now really fatiguing)

Mac OS X and the iMac are keeping two separate sound output volume settings. So the volume setting for the built-in speakers is saved separately from the volume setting for the headphones.
Just connect the headphones and set the volume as desired. Then, disconnect the headphones and set the volume of the built-in speakers as desired. When you connect the headphones, the volume will go back to whatever it was set at before, when you had the headphones connected. When you disconnect the headphones, the volume setting will go back to the previous setting for built-in speakers.
If the above does not work as I described, try resetting PRAM

Then, try it again.

Totally new to this. Audio problems with device and output volume.

Hi, I just purchased Logic Express and Im having trouble with the levels. Im going through an Alesis USB mixer. The problem is, right when I press the record button on a track I start getting a very high hiss and an over distorted sound with my guitar. I played around with the levels a bit and it seems that when I go to the computers audio setting and lower the output volume it goes away. I dont understand why output would effect what Im recording. I don't want to have to lower the outpt volume because then I wont be able to hear the track i just recorded when Im recording on another. If anyone knows what is actually going on and how to solve this problem, any advice would be highly appreciated. Thanks.

Hi, missiontorock.
Could this be a "through-feedback" kind of problem? I don't get any kind of distortion or hiss running through my Edirol M100-FX USB mixer.
Depending on how the Alesis is configured, you might be feeding the same signal from the mixer to the computer, getting that signal back from the computer, and then sending it on to the computer again. This is particularly likely since you report that the problem goes away when you lower the output volume from the computer.
You might look for a 'mixdown' switch on your mixer.
Cheers,
Michael

IMac volume reset upon startup

Upon startup/restart, my iMac’s volume resets from mute to just above mid-volume. I have reset the PRAM several times, and it has not made a difference. I would like my iMac to start up silent like it always has. Any suggestions?

Try resetting some of the hardware involved (PRAM~NVRAM). See this Apple KB for details, etc.:
http://support.apple.com/kb/HT1379
Can't hurt to try, and apparently this has helped others recently.
Failing that, take it to an Apple Store and ask staff there for assistance.

I recently purchased FaceTime from the Application Store. After approx. ±10 meg, the application resets and starts downloading again. I have tried to download it at different times of the day but with the same results. I have been in contact with Apple support and have tried different options with the same result. I cannot download a new Version because in my Purchased List the applicaiton (FaceTime) is still there, and because I have halted it it tells me to resume. I can’t, because the same thing is going to happen. I have tried all the various troubleshooting tips supplied by my ISP and also Apple Support with no luck. I am currently working on a IMac OS 10.6.7. Has anybody got any ideas? Any suggestion would help. Thanks

As I said, I tried everything what the manual says, but hard luck. I have taken an appointment for today, lets see what happens.
Also there is no activity on unit when I use the remote. The unit is stuck on the first page itself where we have to choose the language. The unit seems to be fine to me but the real problem is remote does'nt have activity. The IR is not responding while pressing any of the button.
Good luck with your appointment.
Not much consolation but even new products can have issues and might need a trip to a store to return/replace.
The reason i asked about the LED on the AppleTV is that occasionally it thinks it's paired with a specific remote and ignores others - the unpair keypress I described is quick and free.

Increasing Output Volume?

Hello all,
I have a 15" macbook pro that I purchased over the summer. I've noticed that my volume doesn't go nearly as high as my friend's macbook pro, and he has an 13" model that is older than mine. Is there any way I can increase my maximum output volume? I have already adjusted my sound settings in system preferences, but there is nothing to make it louder. Is there something I'm missing here?
Thanks

If it's iTunes you're listening to, make sure the volume slider in the iTunes window is turned up all the way, then use the master volume controls (the F10, F11 and F12 keys) to regulate the volume. If the iTunes slider isn't up all the way, it limits the maximum volume that you can get by turning the master volume up. At least this has been my experience.
