Mac Pro :: No Sound From Line Out And A Red Light In Optical Line Out
Aug 2, 2009
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.
Double poll here. There are two questions: How much DATA do you have Oo-line?
This is data and not total capacity. This includes all your on-line data: music, images, video, the OS, all of it. It doesn't include back-up data even if it's on-line like Time Machine tho. Just active data.
And of the on-line storage devices used for that DATA totally, what % are they filled to?
For example if you had two 500 GB drives and about 400 GB of data you would answer: "I have < 500 GB of DATA on-line." and,"My on-line storage is between 25% and 50% full.".
i'm having some issues recording in garage band which should hopefully be easy to clear up. i record an instrumental track into garage band through the line-in jack in the back. the track shows up in garage band just fine and plays, but i'm running into trouble recording while that track is playing. i plug my headphones in so i can try to hear the track while i am recording vocals, but i am unable to hear the track. i checked the inputs/outputs in system preferences and output is set to headphones, microphone is set to line in. so i'm not too sure what it could be.
getting my audio from an XBOX through the Optical Audio Input to play through to the Line Out port.The Input tab of the Sound Preference is set to Digital Audio in and is receiving a signal on the meter but no audio plays through to the speakers plugged into the line out port.
I've two problems with my new Mac Pro.The one that's discussed here.and an intermittent "plopping" sound through my Line-Out even when the line-out.is muted (e.g. while playing a game with headphones).It sounds like connecting and disconnecting an audio cable.I've connected my amp via a klinke cable to the line-out of my Mac Pro.
Seems like it should be a straight forward deal, but it's not obvious how to make this happen. I can tell the audio is coming in, as the input levels are reflected under System Pref's. But I can't hear the audio on the line-out speakers and there doesn't seem to be an option to explicitly route the audio.
Power PC 17" Powerbook, 1.67 speed, 1GB Ram, 9GB available, stay up with all updates...all of a sudden only Internal Microphone and Digital In appear. Did Permissions before and after update, tested with plugs in and plugs out of line in and line out, so Whassup?
Alright, this is really annoying. I've been trying to record myself playing music on imovie to show people, but my line in won't pick up any sound! I've tried system prefrences>sound>line in and turning it all the way up and I've tried Utilities>Audio MIDI>Line In and turning that all the way up. I've tried everything I could think of and NOTHING is happening!
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.
I'm trying to plug in and use an external microphone to record a screen capture. Sound gets through the headphones great but, looking at Input Sound in the Sys Pref, the Line In device does not pick up any sound when I speak into the mic. If I switch it back to the Built-In Internal Microphone device it picks up my voice fine. In the Audio MIDI Setup, the Built-in Input device is selected as the device to be used for sound input.There is a switch on my headset to mute or unmute the mic and I've tried it in both positions. There is a volume dial on my headset (presumably for the headphones) and I've fiddled with that too. I've moved the Input volume for the Line In Audio Line-in port device all the way up and still it hasn't picked up a thing. I have a Mac os x Lion on a Macbook Pro and using a 3.5 mm mini-jack headset with two cables, one for the headphones and one for the microphone.
Info: MacBook Pro (15-inch Late 2011), Mac OS X (10.7.4)
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.)?
I have a 2nd monitor and hooked up my xbox 360 to it. I have it connected through HDMI and then have a regular audio jack going from the monitor to my Mac Pro. When I open up my sound preferences and select: Line In - Audio Line In the "Input Level" bar goes up and down meaning it is registering or hears the sound coming from my xbox.
For some reason though, the sound will not output from my Mac Pro. My speakers which are connected to Line Out: Built In Line Output still outputs sound coming from my mac pro but it won't output the sound from my 360. Is there a remedy for this?
So quickly again.
Line In - Audio Line In is "hearing" the sound from my xbox 360 as the "Input Level" bar goes up and down.
Line Out - Built In Line Output still outputs sound from my Mac Pro but not the 360.
My line out port on my late 2007 white macbook recently died and I no longer have AppleCare. I never use the line in port on my computer and use the line out quite alot. I have tried all kinds of fixes to fix the problem but nothing works. I would like to use the line in port as a line out port. I am not sure if this is possible so I thought I would ask here if anyone knew of a way.
I just got my Mac Pro, and I noticed that when I plug my ViewSonic's built in speakers to the Line-Out port on the back the sound doesn't come through. It does, however, if I plug them into the headphone jack in the front.
What am I missing here? This is strange to me coming from several generations of Power Macs.
i just bought Mac pro yesterday when i tried to make update for my apps it tells me that i must make update for my software to allow making the updates
my quesion is if i made update for my software i will lose my apps?
I am trying to record a talk from my MD player using the line-in on my macbook, but I have no idea how to do it. (I have selected the line-in in the input and it shows that it is receiving the input, but there is no sound.)
I have a feeling they'll eventually phase out the MacBook line in favor of the MBP/MBA notebooks. The 13" MBP is almost the same as the MacBook in terms of specs, the only real difference being the aluminum uni-body, which should really be included in the entire MacBook family anyway. I can see how the Air and Pro are two different beasts entirely, but the negligible differences between the 13" Pro and the regular MacBook no longer makes sense to have them separate. The white MacBook is also starting to look a bit dated.
i was just wondering when does apple usually do the laptop refresh with new hardware etc?
I am asking because my current macbook, is causing me issues and I don't want to buy a MBP now if the laptops are going to be refreshed in a few months
I have a mac pro (intel) and macbook pro (intel). OS X 10.6, both without modems. I need to fax maybe 1-5 pages a month and am tired of going to the local mailboxes etc. And paying $1 page. My multiprinter Canon MP500 does not fax. I know I can join an efax type system but that's $80 a year. Are there any software programs to download and takes care of 'Sending" faxes without a modem or fax machine. Looked a pagesender but that requires a efax type of account. Just want to convert a scan into a fax and send it without adding another telephone line or piece of hardware.
I've got some synths connected to a mixer, which I've got going into my Mac's line in. It hears it fine, and I can record what's coming in via a wave recorder, but I want to be able to HEAR what is coming in too. I mean like, have it playthrough the computer and right to the speakers.
In Pages, I need to put a line graph into a document, but I can't get it to look the way I want. Is it possible to put the labels on the y-axis, with the numbers along the x-axis? I have all the data in the graph, but it's just not oriented correctly; and the orientation in important for the class this document is for.
i just bought a used macbook, for about 1 year now there has been a red pixel line on the lower left side of the screen and the pixel line runs about 4 inches up, i ran a pixel check and tried massaging the screen and nothing works, i ran a program called PiXel and found out that it turns red on red, yellow on when all the other colors on the screen are blue and And it turns reddish when all the other colors are blue, it turns orange-yellowish when all the colors on the screen are black and its white when all the colors are white.
now my question is do i need a new lcd screen? or do you believe it's one of the connectors? or do you think its the logic board?
I Have reason to believe that Arrendale Processors will not be coming to the Macbook Pro line anytime soon. As you all may know Apple is currently using NVIDIA as its primary chipset. If apple was going to transition to Arrendale (nehalem) processors, they would likely use NVIDIA as their primary chipset. BUT there is a battle between NVIDIA and Intel (because of licensing) and Intel will not let NVIDIA make chipsets for its Nehalem micro-architecture, So if Apple was to transition to Arrendale they would likely have to use Intel's chipset (which is also their intergraded graphics) or they will have to stick with Penryn as their processors and use keep using NVIDIA as their chipset.
So once in a blue moon I have to step back in time a bit a send someone a fax. Its seems like I should be able to fax anything as long as it is "scanned" into my computer. Is it possible to send a fax from my Mac without a phone line, through my cable modem internet connection?
Trying to install a .pkg from the command line in single user mode. I'm using the command "installer -pkg Installer.pkg -target / The .pkg is on a mounted USB drive. / is also mounted. When I run the command, the screen scrolls to a new blank line and stays there but nothing happens. The light on my USB indicates no data transfer is happening. I get no output, even if I add -verbose to the command.
I plugged in my speakers I used to have plugged in to my Mini Mac to the audio line out on the back of my new Mac Pro, and it doesn't produce any sound out the speakers. Yes, I know how to toggle preferences for audio line-out. Makes no difference. When I select "line-out" in preferences, my speakers will play through the front headphone jack, but not the audio line-out on the back of the machine. Why does audio line-out not work like it did on my Mini Mac?
I have given up gaming and want to focus on large photoshop art pieces (raster, poster size printable). I want smooth, lag-free performance and I tend to lean away from all-in-ones like the iMac so was going to get a 6 core Mac Pro. That said, I likely do not need the expandability of the Mac Pro but I am willing to pay a bit of a premium to ensure the best long term experience. I'm just not sure there is a solid benefit for the extra cost of the Pro. I'm also somewhat clueless about and dubious of the idea of laptop processors in the iMac. I've read some of the posts about iMac vs MacPro before but now with the upgrades to the iMac and the MacPro announcements I was hoping some of you could provide some solid advice on which route I should take.
