MacBook Pro :: Audio Out Stuck On Digital Output After Running A HDMI Setup?

Apr 29, 2012

So while at a gig last night with my band, we ran a video from my computer to screens on stage. The chain looked like so: 

MBP -> Mini-DisplayPort -> MDP/HDMI converter -> 4-way HDMI Splitter -> LCD Monitors 

Now sometime during takedown, someone just decided to unplug something from my computer without consulting me or taking any proper precautions. Now my audio is stuck on Digital Output (type digital optical out). Here's what I know, and what I've tried.I have reset the PRAM/NVRAM?I have killed coreaudio a few times with no luck?I have deleted without progress:

1) com.apple.audio.DeviceSettings.plist

2) com.apple.audio.SystemSettings.plist

3) com.apple.systemsound.plist

I have restarted my computer?I have attempted to use Audio MIDI Setup?I have googled:

1) com.apple.systemsound

2) macbook pro stuck on digital out audio no red light

3) force resetting to internal audio osx

4) force reset coreaudio osx

[code]....

MacBook Pro :: Digital Audio Output (HDMI) On It When Cinema Display Is Already Connected?

Apr 22, 2012

I would like to connect my Macbook Pro to my hometheatre via HDMI. Normally no problem with the mini display port and an HDMI adapter, but the port is already used for the 27" cinema display... Is there another adapter available that let`s me connect both, an HDMI device and the cinema display to my Macbook? I only care about the sound - I want to get digital sound to my receiver. (I am not interested in the solution via airport express and then connect via analogue audio cable - I am looking to get a digital sound signal all the way through...) about Macobook Pro: mid 2010, 17", Processor  2.53 GHz Intel Core i5, Graphics  NVIDIA GeForce GT 330M 512 MB)

MacBook Pro :: Stuck On Digital Output - Internal Speakers Not Working

Jul 12, 2009

The sound output in my Macbook Pro has been going in and out now for a number of months. And yesterday it finally got stuck on "Digital Output" meaning when I take out headphones from the jack, the internal speakers do not work. I am planning on taking it in and wanted to know, since I am still under warranty will Apple repair it, or give me a new one?

MacBook Pro :: Turn On/off S/PDIF Optical Digital Audio Output Manually?

Jun 11, 2012

My sound card seems to be meesing up. It switches back an forth from "Internal Speakers" or "Headpohones" to "Digital Output". For some reason the optical source keeps getting flipped on and is really annoying. I tried blowing out dust to see if that was causeing the comptuer's confusion, but that didn't work. Until I can make time to go to the apple store, is there anyway for me to turn off that certain connection through terminal commands or something?

MacBook Air :: Can't Set Audio Output To HDMI Because Option Not Exist

Aug 30, 2014

I have a (little) problem with my new MacBook Air 2014 (13 inch.) running on 10.9.4 : when I connect it to any HDMI device (Philips monitor or Sony TV through Marantz amplifier) through a mini DP-HDMI adapter, I can't set audio output to HDMI because this option does not exist... However, I have video signal. 

I've tried lots of "solutions", but nothing is working :

     - Shutting down, restarting, sleeping with and without the cable connected

     - Change HDMI cable

     - Reset PRAM 

Finally, I think the problem come from the Macbook because I have an other laptop (a Thinkpad with a mini displayport, with Ubuntu 14.04) and the video and sound are working normally.

MacBook Air :: Can't Get Audio HDMI Output To Work On ViewSonic VX2453 Monitor

Jun 23, 2012

I have a 13" mid 2011 MacBook Air and a new ViewSonic VX2453 monitor. I used the Monoprice mini display port to HDMI converter with audio and connected the monitor to my computer's thunderbolt port. The video works perfectly, but the sound isn't working at all. I set my computer's sound output in settings to VX2453 series (type: HDMI), and I set my monitor's audio input to HDMI. Nothing. I also tried changing the frequency in Audio MIDI Setup, which someone recommended on amazon  for the monoprice adapter, but that didn't work either. 

I tested the monitor's sound by switching audio input instead to "audio in" and connected to my headphone jack, and that worked so the monitor's sound is fine.

Mac Mini :: 5.1 Audio On HDMI Output?

Jun 15, 2010

Does anyone know if the new mac mini models have multi-channel audio out on the HDMI port? or any audio out for that matter?

This has been lacking on the optical audio output of the older models and would rock if it now has this feature.

IMac :: Optical Audio-analog Converter For The Optical Digital Audio Output Port?

Nov 11, 2009

My friend is looking into buying the new 27" iMac Core i7 to replace his PC desktop. The only thing holding him back is that he has an analog surround sound system he uses for his speakers. I am having a hard time myself finding a converter that can make his speakers work in the iMac's optical digital output port. Any products out there that will do that?

Mac Mini :: 3.5mm Jack Accommodate Digital Optical Audio Output

May 4, 2009

I just picked up a new 1.83 core 2 duo at a price I couldn't pass up. I am going to use it as a HTPC so I have my hdmi cable, etc. All hooked up and ready to go. Last bit is the audio but I am having a bit of trouble. I bought a standard miniplug cable and assumed it would plug in just like my macbook. The problem is that the miniplug doesn't fit in the jack on the mini. I understand that the jack on the mini is a combo analog/optical jack but as you see below, it seems as though a standard miniplug y cable should work.

From the Apple support website:
The headphone / line output jack accommodates digital optical audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used.

For digital audio, a standard toslink cable with a toslink mini-plug adapter can be used.I have done my research and some reading and can go out and buy an optical cable plus a miniplug/optical adapter but would rather go the analog route (I understand the quality difference) because I already have the cables and don't have a receiver or speakers, just my tv speakers.

MacBook :: Keeps Switching Between Internal Output And Digital Output For Sound?

Jun 19, 2012

My sound keeps turning off. When I check the settings, the output device switches randomly between Internal and Digital output. I have no idea where the Digitial Output is coming from and this started about a month again. It switches randomly and then I loose all sound for a few seconds. Sometimes it happens once then stops for a few days, other times it switches back and forth for 5 min. No idea!!!

MacBook Pro :: How To Turn Off Digital Output

Apr 11, 2012

So I've posted this question before a few months a go. None of the answers I got helped. This is kind of my last effort before I have to send my baby to Apple and pay God knows how much. I hear this is pretty common, but my audio jack is stuck on digital output. I've got the whole red LED light shining through it deal. I was told it was a swtich in the jack that had been triggered and all I had to do was a) stick a toothpick in it and wiggle it around till it trips the switch. b) spray some compressed air in there. Well I 've tried the first a hundred times a hundred different ways and I just spent 10 bucks on can of air, and that didn't work either.

MacBook Pro :: Audio Not Coming From TV / Moshi Mini DP To HDMI Adapter With Audio Support

Jan 13, 2011

I want to hook my Macbook Pro up to a Sony Bravia (not sure of the exact model). I went to the Apple Store, and was given these two items to hook it up. Moshi Mini DP to HDMI Adapter with Audio Support. Belkin High Speed HDMI Cable - 6 feet

We successfully hooked it up last night, and the video worked. I was told in the store that this setup would not transfer audio, so I already knew there would not be sound coming from the TV, rather from the Macbook instead. My Q is: What's the easiest way to get audio to come from the TV? I'd rather not buy external speakers to plug in, if I can help it.

MacBook Pro :: Output To External Monitor Via HDMI?

Apr 19, 2010

I picked up a MBP 15" core i7 high res laptop on Friday. I actually ordered one of those mini displayport -> HDMI awhile back (was going to get a mini, decided no), however when I hook it up to my plasma it won't adjust the resolution to 1920 x 1080, I checked "display" in system settings but it won't let me push it past the native resolution of the laptop screen.

Any suggestions how to get around this? Also it mentions on the website it can push sound over HDMI now, I wasn't able to figure that out either.

MacBook Pro :: RGB Colour Output Format Via HDMI/DP?

Apr 21, 2012

So i just bought a Dell u2410 screen the other day, and decided to hook it up via HDMI, It's being used for photo-editing, I tried to calibrate it, but in the sRGB mode i need to use the colours come out terrible, Reds are orange, etc. The screen itself, and it's settings arn't the problem. The problem is the Colour output of the MacBook, over HDMI and DisplayPort I've found it outputs the old YPbPr colour format, which for me is useless. if i connect it via VGA it'll output proper RGB colour format, but VGA is pretty crappy, and i ideally need to use a Digital output, I've searched all over the net for a solution, but haven't found one. one thing i did find is it will supposedly output RGB over DVI, but alas i don't have a DVI cable and do not wish to have to buy one...so what i want to know, is it possible to change the output colour format for HDMI and DisplayPort to RGB instead of YPbPr? Note 1: If i boot into Win7 via BootCamp it outputs RGB and has the option for YPbPr... Note 2: It isn't the ICC colour profile that's the problem.

MacBook Pro :: Changing Color Space Output Via HDMI To RGB On 13'

Apr 5, 2012

I just got moved to a MBP 13" early 2011 from Windows. I have a Dell SP2309W monitor which i love. On the winows machine i could select the color space output between ypbpr and rgb and configure the monitor accordingly even with an HDMI cable. I cannot however find the same option in OSX Lion. The ypbpr color space is giving me a headache. I know what colors this monitor is capable of and I don't see them since i moved to MBP, the picture is now kind of purplish, the red color is unnatural ( I doubt a photo would give the idea). No playing around with the color profiles does any good. I'm begining to think that to my MBP my monitor is just a TV. I'm also thinking that a way of solving this is getting a mDP - DVI adapter, so perhaps the monitor would make the RGB mode a priority since it's connected through DVI.

MacBook Pro :: HDMI Output To TV Suddenly Stopped Working

May 28, 2012

I have a one month old "late 2011 model" unibody Macbook Pro where the HDMI output just suddenly stopped working with no changes in configuration. I've tried resetting the PRAM and SMC, switched HDMI cables, cold rebooting everything, tried different HDMI ports, different resolutions on the TV and switched audio output settings, nothing works. When I plug the cable in the Mac switches resolutions, recognizes the TV in the Displays preference panel and correctly identifies it as a Toshiba, but doesn't send any audio or video signals to the TV.
