Mac Pro :: Line Out / In Options In System Sound Preferences Are Missing
Sep 5, 2014
My 2008 Mac Pro recently stopped producing any sound.
The startup chime is silent. No sound comes from the speakers at all and the line out/in options in system sound preferences are missing, although it still lists my Logitech webcam microphone and the volume meter for it responds to sound changes.
Could the sound chip on the logic board have stopped working?
Could it be a virus or a software conflict? I haven't updated the system recently or installed new software, but Skype has been acting erratically and has crashed a few times.
The missing line in/out devices in the sound preferences seems like it might be a hardware problem.
I have tried all of the normal things like checking cables and resetting pram but no change.
I have the same condition whether I boot into my primary drive or into the clone (made before the sound stopped working) on a separate drive or into Windows through Bootcamp.
If the logic board integrated sound is broken, can I add a sound card to take over the audio for everything (startup chime, audio from software and audiovisual sources, Skype, etc.)?
2009 iMac, external speakers connected to analog audio out. No longer work. System Preferences - Sound - Sound Output only shows built-in speakers. Tried zapping PRAM, tried deleting com.apple.sound.plist from /Library/Preferences. Doesn't show in Audio MIDI Setup either.
4. The same machine when booted in Windows (via Bootcamp/CSM-BIOS) plays perfectly and shows Cirrus Logic devices and the HDA devices. This should eliminate hardware issues.
5. I have checked for the Optical Audio microswitch being stuck, but that does not seem to be the case.
6. This was used with Apple Headphones which also have the microphone built-in [URL] ....

Comparing it to another 13" Mid 2012 MBP which has working sound.
When logging onto the mac the other day, a questions mark appeared, upon logon all of my system preferences had disapeared, including Itunes, mail etc along with a number of icons. The machine did do several updates and the icons re appeared, but the Itunes and mail are still missing.
I have seen a few videos about mastering and gave it a try myself. It can be done by clicking the master tab, then going to the Input 1-2 column setting and then clicking setting - mastering, etc.When I first did this a few weeks ago, there were many options such as hip hop mastering, electronic mastering, etc.Now, when I do so, I have different - much less enticing options and have no idea where the good ones went.
Using 10.5.1, no problem up until now (new 2.8 iMac). Working all day with Adobe Lightroom 1.3.1, again, no prior problems.The computer froze, which I noted when the screensaver when I left to go eat dinner stayed static without fading out to a new picture. After force quitting and restarting, I went to the System Prefs and when I went to the Desktop/Screensaver section, I got a blank window. I confirmed all the other System Prefs icons work fine. It's as if the Desktop/Screensaver settings are erased/gone/whatever.
Just upgraded to Lion on my desktop machine (iMac) and laptop (MacBook Pro). iCloud is working fine between my laptop and mobile devices (iPhone and iPad), but not with my desktop iMac. This is most obvious with iCal, which still tries to sync with MobileMe (even though the account info says its been upgraded to iCloud.
This weird, but today's software update deleted all but 2 of my screen resolution options in the display section of system preferences. The 2 remaining options are not ideal for my iMac. how I might restore the options that were lost?
My account setting icon is missing in system preferences. Can anyone provide me with advice on how to fix this problem. Also, whenever I start the computer it makes me log on now.
My macbook pro is an OSX 10.5.8, purchased in January 2009.
I noticed that System Preferences, App Store no longer shows a padlock at the lower left hand corner, yet other System Preference windows show the padlock. Why is that? Is there a way to restore the padlock? I have already tried "repairing" my install and the padlock did not come back.
I've cleared the preference file and system prefs/spotlight caches with no luck. Repaired permissions. It seems the Music icon is holding up the others. If I re-arrange them they break only after "Music." This is in the console after opening the preference pane:
3/8/12 1:18:15.593 PM System Preferences: Missing icon for Music 3/8/12 1:18:15.594 PM System Preferences: Rebuilding icon cache. 3/8/12 1:18:15.773 PM System Preferences: Missing icon for Music
and earlier,
3/8/12 12:33:33.922 PM System Preferences: Missing icon for Applications 3/8/12 12:33:33.922 PM System Preferences: Rebuilding icon cache. 3/8/12 12:33:34.111 PM System Preferences: Missing icon for Music

Friends were having major problems with Mac OS 10.5.8. I tried to install 10.6 but the installation stalled several times. Through it all, I got OS 10.5.8 running for them again but the sound application is now missing, so I can't get the iMac to play sounds effects nor will it show the Harmann Kardon sound sticks as a sound output. They can't find their original install discs and I do not have that version. Will the sound application for system 10.6 work if I drag that file into their 10.5.8 system?
I just bought a 2.4 MBP model a1260. When I got home i noticed the volume keys were not working, and then i noticed none of the function keys were working properly. (example, f12 shows an eject CD symbol). So, the keys are working but not doing the standard functions such as volume and brightness.
I have check and unchecked (and restarted) the "use all f1, f2 as standard function keys" to no result.
Some other wierd things that seem to be related are:
1. In the SOUND window in SYS PREFS all sound effects are greyed out. Under OUTPUT and INPUT it says no devices found.
2. When i go to the itunes store in itunes and i double click on a song, it wont play. Not only is there no volume, but song wont play. Its the same with my own music from my cds.
3. When i insert a DVD no volume control shows up.
And the last superwierd thing (haha) is that I reloaded leopard and when the computer restarted up after install there was no OSX music that normally plays as the video flys thru the starfield.
Headphones have no audio either.Sorry so long. The computer has no warranty of course.
so heres what happend. my macbook has been acting strange. freezing and sound not working at times. system preferemces quitting etc. and i just got it back from its thrid repair. THREE REPAIRS IN LESS THAN 3 MONTHS> so i was downloading a game for my psp when i went to go get a bagel in the kitchen. i left for no less than a minute and when i came back the screen was black. i thought it just dimmed itself but no. i moved the trackpad clicked on all buttons click the mouse button everything. i noticed the light wasnt throbbing so im sure it wasnt sleeping. the light was just pure white(the sleep light) so i waited like 3 minutes than shut it down. do u know whats happening. i know now i will be getting it replaced but until then im trying to keep it working well enough that i can watch a ********** vid on youtube.
I watched a video and it was very loud so I went to System Preferences and turned the sound down.But now I can't mute by clicking the F9 button as I normally can. I can mute by going to System Preferences but I don't want to do this.Before I changed the volume in System Preferences, the keyboard keys worked fine for volume adjustment. I could make it quieter, louder or mute.I have tried with checking and not checking the option to display volume on the screen (in System Preferences).

I've had this problem since Friday with my Mac Pro (March 2009) and haven't been able to solve it.
On Friday my speakers suddenly stopped working. After first having confirmed that the speakers were working with another source, I tried headphones both in frontal headphone slot and with the analog line out in the back, both without success. There's a red light in the optical audio out, indicating that it's on for some reason, although I have selected different audio out source. The internal speaker works just fine, only the normal audio out doesn't give me anything.
I found a thread in the MBP section similar to this problem, but solutions for MBP didn't work.
This started happening randomly earlier tonight, and I haven't managed to find a fix just yet.I was encoding a video file for quite awhile (I don't think that parts important, but I thought I'd include it anyway) and then I tried to play a youtube video. I noticed there was no sound, so I tried to up the volume using the Volume Up key on the keyboard. The volume visualisation appeared on the screen like normal (albeit a bit laggy), but the sound still didn't change, neither did I get the usual 'click' noise you get when you change the volume.I went looking into the sound options in the system prefs. only to find that the Output Sound device was headphones. For a test I plugged in some headphones to see what happened and, low and behold, the Output Sound device changed to the Internal Sound and my speakers were working again, but only with the headphones plugged in.
I have a macbook pro (late 2007-2.4ghz). Nearly a year ago I had my logic board changed as there were no display on the monitor though my computer was working. They said it is a production mistake and my logic board would be changed even if it was not on warranty.But now when my computer overheats a green vertical line at the left side of my monitor displays. when it cools this line disappears.know 17 inch unibody macbook pros had same issue with 9600 gts graphic cards. My graphic card is 8800m gt. Is there a solution for that or I had to change my logic board again?
Anyone think this is a good deal? http://www.amazon.com/Apple-MacBook-MB003LL-Laptop-Processor/dp/B0006HU4DK/ref=pd_bbs_sr_1?ie=UTF8&s=electronics&qid=1227225131&sr=8-1. I bought the Rev B, but had to return it because of 5 dead pixels in the center and the horizontal line issue. I am thinking of saving over $1,000 by getting the above. It is new/in box and from amazon. This is the best deal I have seen. It is even cheaper than the refurb models at apple.com.
I'm not talking about the System Preferences app itself, I'm talking about the settings within the app. So for instance, the security settings, and the mouse settings, energy saver, etc.
Where can I find the settings files on my Mac so I can back them up?
now 8 months old macbook unibody (6,1) has a line missing in the lcd panel. Will apple replace it?
I really think it's a display issue. I've done the usuall supects (pram,reformat,repair premissions and everything).
And sometimes I get white boxes in the screen, but it passes the hardware test.
I've posted an screenshot with the line that's missing painted in red.
Edit: An screenshot of the mystery white box Edit2: Found out what is the problem of the lcd, it's one of that two polarizing filters that has fallen a little. Still not sure if apple will cover it
I have a 12inch powerbook 1.5ghz (Most recent of the 12inch PowerBooks) running 10.4.8. Its a very clean install (Format and re-installed last weekend). I started using a bluetooth might mouse during the week. Since waking my computer up from sleep I get Bluetooth: not available. Bluetooth options have all disappeared from preferences. I have tried:
Rebooting Unpluggin power and removing battery for 60 seconds. Resetting nvram and restoring defaults. Deleting the bluetooth preferences file.
If i plug in a usb bluetooth adapter it works fine.
I got my second Mac Mini. I decided to get the Server Version because I liked the hardware (2 500 GB drives) and I wanted to play around with the Server Features. The Apple Guy at the Store did not indicate there was any of the client software missing on the Server Version. He mainly just said it was missing a DVD Drive which I new. Being fairly new to the Mac OS I was not really sure what to ask. My background is many years of Windows Experience (server and client). So, I kind of assume it would have everything the normal Mac OS has plus all of the Server Add-on's (like the Windows Server). Was I wrong, is it missing more then just iLife? I understand iWork does not come on either version.
There is no "copies & pages" and "quartz filter" on my print menu. I've have tried my darndest to print in black and white to no avail. I also can only print one page at a time. The options are just not there. Why? And how do I correct this?
Icloud is missing in my preferences (intead i only find mobileMe wich i do not want to use anymore. I just upgraded the system (it's now 10.6.8) and nothing changed.
I am unable to select certain options in preferences. In Sharing, there are lots of things I cant do. Right now I'm trying to set up external hard drive for time machine and I am unable to enter my Home name, its greyed out.This happens a lot.
