Mac mini audio output problems

This is similar to a problem that appeared before, but with a different twist.
On 4 July all was well. On 5 July I switched on and there was no "chord" from the Mac. When I collected my mail - no sound from my speakers (which are part of my screen). Logged on to a couple of sites - no sound.
The System Profiler, under the "Audio (Built In)" category, says: "No Built-in Audio." I know that's wrong because it's always worked before and when I plug my headset in it works fine.
When I go to the Sound preferences panel in System Preferences, it finds the headset but if I unplug that it finds nothing.
I tried running the hardware test (by putting in the OS X install disc and holding D during startup.) It couldn't find a problem.
So, as far as I can see, audio output is fine for the USB headset output but not for the others. Is there a simple fix? The nearest Apple store is about 200 miles away and I don't fancy the idea of posting the Mac off.
(And I think it's still under warranty for a couple more weeks.)
Mac mini Mac OS X (10.4.10)

hello mini users with the "no audio output" problem
it seems that there are faulty output jacks in the macbook and the mac mini
there are two things you can try:
i tried everything and began thinking about what new software i had installed. it was "macam" which enables you to use older webcams on OSX. i needed that to use my webcam on skype.
macam installs a file called "macam.component"
if you have the same, do this - take that file out of:
(your hard drive)/library/quicktime - macam.component
and just put it on your desktop
restart, then in your sound pref's choose your audio output (if doesn't work restart again)
the first time i took it out, i had my sound back instantly, another time i had to choose audio output in sound prefs. you kind of have to try different things. after you get your sound back, you can put back "macam.component" to use your webcam.
it seems macam causes the problem, the two can not work at the same time.
the second thing: if you dont have "maccam" try plugging and unplugging output jack a few times and restarting until you have sound.
the problem still could be with the OSX 10.4.10 update / quicktime...or maybe even a hardware problem like others with macbooks were saying (with the red light), not sure.
people with macbooks and who have the red light on, say to use a paperclip to turn off the switch inside.
my mini does not have a red light on. i tried using a paperclip but it doesnt work.
hope this helps, beleive me i feel your pain!!!!
what good is a computer without sound?
extremely annoying problem that i hope apple looks into and fixes

Mac mini audio output

Hi, i've seen this interesting program http://www.algoriddim.net/index.html
for djs.
These djs program usually use to way to work:
- dual sound card
- mutiple output on a single sound card
This program use the second approach.... but mac mini has only an output.
I remember that my last pc was able, using a tune program, to convert an audio input to an audio output to get 5.1 system.
I wonder to know if it is possible to convert the input to output with some kinda program, or is there any way to get working the pre-cue with a mini.

Mac Mini HDMI Output Problem w/ LG L246WP

NOTE: This appears to be unrelated to the "screen flickering" that has been noted previously.
I'm using a fresh new Mac Mini 2012 with an LG L246WP LCD monitor. The monitor has HDMI, VGA and Component video inputs.
When I attach the monitor to the Mini DisplayPort output, using a Mini DisplayPort to DVI adapter connected to a DVI to HDMI cable, the display functions properly at all resolutions - including the native 1920 x 1200 resolution that I use it at normally. All resolutions are clearly displayed in the "Displays" System Preferences pane. The display looks perfect, functions properly.
When I attach the monitor to the HDMI port using an HDMI cable, the display does not fucntion properly. The display is shifted about 80-100 pixels to the left and about 20 pixels up, creating black bars on the bottom and right sides. Because of this, a large portion of the display is not visible including the menu bar and most of the left side. Additionally, the settings are reduced to "Best for Display" or "Scaled", with resolution options under "Scaled".
This is not acceptable. I had planned on simply using the Mini DisplayPort output as a workaround, since I already have the DVI adapter from an old setup, but I need to use Thunderbolt to access external hard drives for rapid data transfer. One of my Thunderbolt accessories does not have two ports, so I can't simply add the Mini DisplayPort adapter to a chain. The HDMI port needs to function properly with my monitor.
It's important to note that this monitor has functioned properly with many other comptuers running OS X, Windows and various Linux flavors and it hasn't ever done this before. I've tried several different HDMI cables, ruling that out as a problem. I've tried the HDMI to DVI adapter that ships with the Mac Mini 2012 along with two different DVI to HDMI adapters, ruling that out as a problem. I tried attaching several HDMI devices (game consoles, DVD players, etc) and they all function properly, ruling out an HDMI issue as a problem. The monitor functions properly when attached through the Mini DisplayPort to DVI adapter, so it's not a problem with the monitor. I've reset the PRAM already and the installation of OS X 10.8.1 is stock with no modifications or migrated data. I've tried the suggestions on the HDMI FAQ (although there's no "underscan" option available in Displays)
I tried to call AppleCare and after describing the problem I got disconnected with no callback. I started another ticket, described the problem, discussed the previous disconnection, was assured that I'd be called back if disconnected, and haven't heard back in two hours. So I started to dig into the problem in earnest.
This gets pretty technical.
After substantial research, it appears that this issue is related to the EDID that the monitor sends to the computer and, crucially, the way that the driver responds to it. For some reason, the HDMI port is recognizing the monitor as a CEA device instead of a monitor. As a result, it's restricting the monitor's available resolution to the native resolution that the CEA 681 Series Extension describes ("Best for Display") and all other resolutions (including 1920 x 1200) are only available as "scaled". For some reason that I can't discern, all resolutions (even the 1080i and 1080p options) have similar deformities.
I've attempted to fix this by placing an appropriate override file in /System/Library/Displays/Overrides with an edied EDID removing the CEA-enable flag from byte 127 but, even after a reboot, the OS still insists that it's a CEA device and it won't allow me to force it to recognize the monitor as a 1920 x 1200 LCD Monitor.
How did I come to this conclusion and develop the fix? A nearly identical problem description showed up on the following website, with details on how this user fixed the issue:
http://byuu.org/articles/computing/edid
They used a convoluted process that involved dismantling the monitor and flashing the EDID on the monitor itself. It fixed their problem. I'd prefer not to go through that process just because one computer has a problem with it. Frankly, I'd prefer if the new Mac Mini performed properly in the first place.
TL;DR: The Mac Mini 2012 doesn't work right with the LG L246WP through the HDMI output. Everything else works fine with it. This is very uncool. It's most likely to be an issue with the driver for the Intel HD Graphics 4000 GPU that are bundled with OS X 10.8.1. The Mac Mini 2012 won't update to 10.8.2 (yet), so I can't test it.
Anyone have any other ideas? Anyone else using a Mac Mini 2012 (or 2011) with an LG L246WP monitor? Anything simple I've missed?

Problem Resolved. But it was complicated. And a huge pain in the rear.
TL;DR: I flashed the EDID as described here. This is not recommended for the weary. Ideally, Apple should release an update OS X that will include the updated Intel HD Graphics 4000 drivers that utilize the CEA flag properly.
Here's the detailed version. As mentioned above, this isn't recommended for the weary. An improper (or interrupted) EDID flash can have seriously unpredictable effects on a monitor's performance.
Step 1: Get a Windows PC set up with a floppy drive and find a floppy disk. Use this system to format the floppy as a MS-DOS Boot Disk and copy over the "ddcw" program described at the aformentioned link.
This took awhile, but I was able to cobble together a temporary frankensystem with parts I had laying around. In installed XP and formatted the disk with XP's format tool.
Step 2: Grab EDID data from the monitor, modify it to disable CEA mode at bit 127 and make sure bit 128, the checksum, is appropriate.
This also took awhile. Several graphics cards I tried could not read or write EDID data. I ended up swapping AGP cards in my frankenstein box until I found one that worked - a generic GeForce4 4200.
Once the EDID data was written to the floppy, I edited the text file containing the EDID data to change the last two hex octets from "01 33" to "00 34" (00, to disable bit 127, and 34 is 33 + 1, which satisfies the checksum) and formatted the text file to match the sample included in the EDID_Write.zip file. Your mileage may vary - make sure the checks.
Step 3: Write EDID data to the monitor.
The link above mentioned three options: Easy (monitor's EDID is unprotected - write away!), Hard (monitor's EDID is protected - use service mode to attempt a fix), and Very Hard (monitor's EDID is protected, hardware modification is required).
Luckily my LG246WP simply needed to be put into service mode as described at the link above (menu + power) and once started up in service mode, I simply enabled "Aging Mode" (whatever that means) and attempted a DDCW write of the updated data.
Step 4: Profit!
After doing this, I powered off the monitor and powered it back on with the Mac Mini attached. The display functions PERFECTLY with HDMI out, just as it does using the Mini DisplayPort to DVI adapter.

Mac mini video output problems

My mini is one bunch of problems, here is what im dealing with,
On my screen i have 2 systems connected, when i switched bac from my windows pc to my mini, my screen says no signal. I can press the keyboard etc, nothing happens. Same as when the mini goes into sleep mode. It wont wake up . Si i have to reset the mini all the time. What is causing this and how could i solve it. The mini is connected with hdmi.

Hi, JO5B.
I have Dell Monitor that has 3 computers plugged into different inputs.
When switching between different machines I have to select the new input from the monitor's on screen menu. The Dell doesn't auto detect the new input and switch itself over.
Try a manual selection from the OSD, that might solve your problem.

Is there a way to connect the Apple TV as a second display without it automatically changing my Mac's audio output?

Is there a way to connect the Apple TV as a second display without it automatically changing my Mac's audio output? I would prefer to use an audio interface for playback and the apple tv as a third display. I know I can go back to system preferences and swap my output back manually, but it is getting to be really inconvienient. Thoughts?

2014 mac mini dual monitor problem

I just brought a mac mini (Late 2014) i have two displays monitors connected, one HDMI to DVI. and one thunderbolt to DVI. I can have both thunderbolts connected and the problem its the same, when back from sleep ,one monitor doesn't turn on. i have to disconnect one and then both work, it only happens when the mac goes to sleep. on cold restart or turning the mac on, this problem doesn't occur. any help.

I have this same problem too. I purchased the Mac Mini with the intention of running dual monitors. I'm using the HDMI and mini-display/Thunderbolt to DVI. I've also tried MiniDisplay/Thunderbolt to HDMI and I'm experiencing the same problem as angelfromfullerton. Whenever it tries to wake from sleep, it can't decide on monitor arrangement and keeps flicking between the two, making the OS unusable and forcing a reboot... EVERY TIME. I've also experienced the issue once or twice on a cold boot. It doesn't matter which Thunderbolt port is used either.
I'm going to have to return my Mac Mini unless this problem is fixed asap.
Mac Min, OSX Yosemite (10.10).

Mac Mini with Major Problems

I'll try to make this short, but it is a looonngg problem.
About one month ago my Mac Mini began having problems when I boot up. The computer would freeze on the opening page where I put in my password. My wireless keyboard and trackpad would not work. This would be interminent at first but progressively got worse.
I spent hours on phone tech support. Finally realizing that would not help I drove the 100 mile round trip to the local Apple store for a Genius bar appointment.
The first appointment (there have been 5 - meaning 500 miles) resulted in them doing a clean install of Lion. I took the computer back to the office and guess what, the same problem.
I drove back to the Apple store, the Genius did some more work and proclaimed it fixed. It was, for about 3 days when everything started again.
More time now on tech support. One more trip to the Apple store.
This time they kept the Mac Mini for about 4 days are replaced the logic/mother board.
I got it back to the office on Thursday. Everthing works great.
Until today. I boot the computer, it gets to the screen that has the apple on it - then nothing.
I manually power it down and reboot. Same thing.
I've set up ANOTHER appointment at the Genius bar tomorrow.
My question: can I demand that they replace this machine. Between work and home I have 2 Mac Mini's, a Macbook Pro, a Macbook Air and 2 iPhones. I've never had this type of problem. I'm really tired of this.
I purchased this in February so it is in warranty.
Thanks

Excellent new, sorry you had so much trouble on the way. And yes, Apple Stores are awesome!

New Mac mini audio problem - beeping from audio output

Hi Apple fans
Please help me. I recently purchased a new Mac mini from my local store. It's three-and-a-half weeks old as of today.
It's an i5 2.3 with 8 GB of corsair RAM.
I like to watch movies and TV on it and have the audio connected to an external amp and speakers via the headphone output.
After a reboot today I lost the sound through that output. All that I hear through it now is an electronic beeping, six notes, descending in pitch, repeating.
I have no idea what it is, other than annoying since this happened on a brand new computer. Not looking forward to the idea of losing my mini for a week as Apple figure it out, but it may be all that's left to do.
Maybe somebody here can help me out - anyone have an idea what's going on? I did an fsck -fy already, and there seems to be nothing wrong, based on that check. For completeness sake, I ran the sound over a USB sound card, and the beeping noise was not there, and sound worked fine. Ditto for the internal speaker - no weird noise there, this seems limited to the headphone out port. I've tried different cables, and even amps, and a set of small speakers without amp. The noise is there when using the headphone jack, and it's absent when using the wee internal speaker or USB-based sound. Please help?
I captured the sound on a video which I've uploaded. It's kind of jarring, so keep your hand on the volume button.

Hi Pascal,
Certainly strange, but I have no ideas other than having it looked at by Apple.

Mac Mini Audio Problem

Hi,
My Mac mini is only sending sound to one side of the headphone. I can get sound on the right but no sound on the left. I'm wondering if the sound card might need replacing ???
Any help would be appreciated.

Actually I'm trying to hook it up to my stereo so I was trouble shooting with the headset as I only get sound from one speaker. The Bose rep suggested I try a head phone to make sure the problem is coming from the mac mini. Is it possible to hook up to a stereo via a usb?(USB to Stereo input cables?) Also do you think that would help? I've tried new head phone to stereo cables between the two and same problem....

Mac Mini Audio Intermittent over HDMI, Cuts out with Assertion in kernel.log

Hello. I've been having trouble with a mac mini (Mid 2011) that I bought on Thursday. It's running OSX 10.7. The Mac Mini is the $599 unit.
I've got it hooked up to my Sony BRAVIA HDTV (also this year's model) via HDMI, with audio configured to be delivered via HDMI to the TV alongside video. Initially the audio will play through my TV, but after an hour or two of watching something, it will cut out, and there will be no more sound coming out of the TV from the mac. Ultimately, the only way I can fix it is to reboot the Mac Mini. I've also observed that at about the same time sound cuts out, the following error message appears in kernel.log:
Aug 12 19:21:40 joshs-Mac-mini kernel[0]: Sound assertion "0 != result" failed in AppleHDAWidget at line 3957 goto handler
Aug 12 19:22:10 --- last message repeated 5 times
As far as I know, assertions failures usually mean software problems (bugs). I suspect I may be encountering a kernel-level bug in Lion, as this error message is showing in kernel.log.
The following is a list of diagnostic steps I've taken:
- I've double-checked the sound output device in preferences. It didn't spontaneously change from SONY TV (HDMI) after sound cut out.
- I've tried changing output to the internal speakers. It plays sound from the mac mini (as expected). When I change it back to HDMI, still no sound from the TV.
- I've tried turning off and back on the tv. No effect.
- I've tried unplugging and replugging the HDMI cable. No effect.
- I've tried replacing the HDMI cable with two other alternates. No effect.
- I've tried other HDMI inputs for my TV with HDMI attached. No effect.
- Note: I've got a ps3 and xbox360 on the TV that has successfully used the HDMI inputs and cables tested on. They've never had this type of problem, so I don't think there's a problem with the TV.
- I've tried rebooting the mac and resetting the "PRAM" (Command-Option-P-R before the grey screen on bootup). Sound still cuts out after a while.
- All updates are applied.
Does anybody else have any ideas about what I could try to fix this? This problem is pretty much a deal breaker, as rebooting the mac mini mid-movie kind of destroys the movie-watching experience.
Thanks

I'd just like to jump in on this thread to report exactly the same problem.
2011 Mac Mini (the 2.5GHz i5 model) running Lion, Sony Bravia TV, HDMI sounds cuts out after a while with the console error "Aug 15 18:30:25 Mini kernel[0]: Sound assertion "0 != result" failed in AppleHDAWidget at line 3957 goto handler".
Interestingly, after the error occurs, I can still get 5.1 sound through Plex, but not through Quicktime. 2.0 sound and system sounds all fail until I reboot the system.
Any help would be appreciated. I would prefer not to have to return the Mini.
Thanks.

Mac Mini audio weak

My spouse got a new Mac Mini 1.83GHz currently with OS 10.5.4. The migration process from her old PowerBook went fine. The only problem is the audio is weak. With all sound controls at their loudest and the Sound preferences Output Volume at its max, the sound is low to medium whether in Safari or iTunes. On my iMac it would be screaming if had that setting. I don't expect good sound quality out of the Mini but I would expect enough loudness. Also, the ViewSonic monitor being used has the same issue when plugging the sound cable into the Mini sound jack.

Wayne my response may not be relevant to your issue but let me share my experience.
I have a Mini 2.0 on a Bravia connected to a 5.1 AV system. The only way I got the thing to blast. Even Harman Kardon Soundsticks were unsatisfactory, hence the 1000w system.
First, the 3.5 audio jack on the Mini connects the 3.5 next to the HDMI on the LCD. (I use a DVI > HDMI for video). Then 2 RCA jacks connect the chosen channel (in my case 'TV') on the LCD to the corresponding channel on the AV Receiver and there you have it.
I have 600g worth of movies and music parked in an external and the 5.1 makes all the difference.
Cheers

Mac Mini No Output Device?

I can not get my sound to work on my Mac Mini! In 'System Preferences' it shows 'No Output Device Found'? There are no options listed for me to select an output device.
If you have any ideas that might fix this problem I would really appreciate your help!
datgrt

do you have any audio apps working?
open one up (quicktime player, dvd player, facetime, skype etc) and look in its preferences to see if it offers you a choice.
do you have a pair of headphones (to see if that provokes a physical connection)?
is this a new problem? if so, whats different?
do you have a cam connected?
in system preferences, does it detect input, as in a microphone?

2011 2.3 GHz mac mini audio got delay

I am using a HDMI cable to connect my mini to a philips LCD with build-in speaker. When i play youtube video or using the text to speech function audio will got delay for half or few sec before u can hear the sound coming out from the speaker. I did call apple care and try to find a solution. They told me is my HDMI cable not meet the requirement. They said i have to use 1.3+ HDMI cable to solve the problem. Then i go out and got a 1.3b HDMI cable and the problem insist. I tried to use the headphone jack to output audio to a normal PC speaker, the audio work perfectly fine and no delay. Then i tried to use the headjack to output audio to my Philips LCD and set the output source to use headphone output, but no sound at all. I am hoping to use my Philips LCD speaker to output audio so i dont have to use another speaker on my desk. Hope someone can solve my problem. Lastly sorry for my bad English
so i have 2 problems:
- using HDMI to HDMI cable connect to a LCD with build in speaker, audio got delay.
- using mac mini's headphone jack output audio to my LCD while HDMI cable connected to it cant switch the audio output to use headphone jack output.
btw i am using lion 10.7.2 , thx

I have a MacMini Late 2011 with 2.3 GHz I5 and 4GB RAM and I use it as media center... It's enough to play FullHD movies but it uses 256 on 512 MB of (shared)RAM... I don't think that you can use a mini for hard gaming...
But AngryBirds Space on a 60" FullHD TV looks great

Mac Mini Audio Issues

I just got a new Mac Mini about a month ago. I have a setup of speakers that used to sound great with my computer, yet at times, especially when music isn't playing, a crackling, distortion noise is prominent. I don't think my Harmon-Kardon Soundsticks are at fault, because when plugged into other sources, they sound fine. Now this distortion noise happens all the time; I just can't enjoy my music, felling that it isn't at its full potential. If anyone is having the same problems, if anyone one knows how to fix it, please answer me- I need help. I don't know if I should complain to Harmon- Kardon or Apple about this and my warranty doesn't last forever.

Yep, I'm having the same issue but with some analog Philips speakers. They work great on the PC box I have as well as my G4 Mini.. I thinks Apple cranked up the output of the analog "head phone" port so they would have ample volume to drive head phones, but know line level analog speakers get over driven. May be time to find an audio attenuator, cause I don't want to change everything to USB..

Mac mini external speaker problems

my mac mini using an audio interface (Lexicon: Lambda) and linking with external speaker (ADAM: A5x). they can play music and video smoothly before Mavericks update recently. After the updated, I can't play music and videos with iTunes and youtube smoothly, but it is ok when played with internal speakers. I had tried to clean up my desktop files, emply trash, and release ram by OnyX, but all these does help, and i don't know wheat to do now, pls help! Thanks!

thanks all, I fix my problems finally!
I just tried the following process and then the probelm solved
1. turn off mac mini
2. unplug the usb of my audio interface
3. then change another usb port at the back my mac mini in order to plug my audio interface again
4. turn on mac mini
and it is smooth and fluencent when i play songs and videos on my mac mini now.
exactly, I don't know why my problem can be solved this way... but anyway...
this works for me!
