Mac Mini Sound problem

Hi all,
i have a mac mini early 2009, the sound dont work and i run apple hardware test and show me following error 4mot/1/40000002 master-0
Any ideas to solve it or explaint what happen?
Thanks for the help

The error points to an error with a fan? Is the Mac mini still under warranty? Bring it to an Apple Service point would be the best option.

Mac mini sound problems

I can barely hear sound on you tube videos with my mac mini. Sound system is on highest. Sound on some videos on Facebook site and on other sites sound fine. What could be the problem?

Sounds like a problem with those specific videos.

My Mac mini sound problem

Hi!
i put my mac mini in the living room and connect it to my amplifier, it is working fine until my daughter use some bluetooth earphone and now when I go into the System preference --> Sound --> input/output All I see is the bluetooth device, but no buildin speaker.
How should I do to bring it back ?
(it's a mac mini I bought for 10 month, installed with 10.6.1)

Hi jameshsi
Go to: Applications > Utilities > open Audio MIDI Setup and select Built-in Output.
If that does't work go to: System Preferences > Bluetooth and uncheck the ON box.
Then if that still doesn't work, then ask the Bluetooth expert (your daughter) to undo the settings and return control of the Audio system to you.

Mac Mini sound continually turning down

My mac mini sound is continually turning down. When I hit the sound up button, the sound goes up for a millisecond and then goes back down. It is really annoying because the sound up icon is in the middle of my screen. This problem has been occurring on and off for a week now.

Ok I found out how to fix it. I deleted my audio cache and it hasn't done it again.

My mac Mini has problem rendering images and video

THE PROBLEM:
My mac mini has problem rendering JPEG image. There are strips on the images. Other images such as GIF, PNG, TIFF, and BMP are displayed nicely.
The images shown in the links below illustrate the problem:

http://www.flickr.com/photos/terencewong/73360989/
(Please note that this image is grabbed from my faulty Mac Mini and saved into TIFF. For uploading purpose, I converted it into JPEG on ANOTHER computer.)
For movies, AVI can be playback without problem. But when it is converted to MPEG, it looks like an untunned TV channel.
FIXES TRIED:
I did erase and install 3 to 4 times using both the install disc and my Tiger Family Pack. All ended up with strips on the JPEG images and the generated MPEG movies.
I've also tried to flash the firmware to 113-xxxxx-124 using ATI's october 2005 universal ROM update, however, the ROM Revision shown in System Profiler is still 113-xxxxx-116 no matter how many time I reboot the system.
INVESTIGATION:
Yesterday, I did some research and got to know that JPEG and MPEG are using DCT (Discrete Cosine Transform) for decompression. And the ATI Radeon 9200 chip provide such a transform on hardware basis, which free the CPU from doing something else. Feel free to point out my inaccuracy.
HARDWARE SPECIFICATION:
I bought the Mac Mini in the last Februray.
The system Boot ROM version is: 4.8.9f1
Display card is ATI Radeon 9200
Chipset Model: ATY,RV280
Revision ID: 0x0001
ROM Revision: 113-xxxxx-116
A POSSIBLE CONCLUSION:
I suspect that it is this part of the chip (the DCT) that is faulty.
Anyone know how to fix this problem?
Many thanks!

Assuming that your display is tightly connected, thus the problem is not caused by something as simple as that, the fact that a full erase and install has not removed the problem would, I think, point to this being a hardware issue, and given that everyone's mini (with the possible exception of some of the latest ones) has the same video chipset as yours, and do not suffer the problem that you appear to, it seems very likely that your mini has a fault which is in need of repair.
If you have an Apple Store nearby, I would take it there to have it checked out - at the very least they should be able to replicate your problem using an in-store display, and if not, thusly suggest it's something external to the mini and concerning your display or something very unusual in the immediate environment of the mini. If you don't have an Apple Store in reach, I'd take the system to an Apple authorized service provider since at the present time it is under warranty.

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 startup problems

My Mac mini usually runs fine, when Im done using it I put it to sleep, when I need it I tap any key on the keyboard and it
usually wakes up. I have noticed that when we watch videos that are downloaded on the computer with Quicktime Player
that the computer does not wake up with a tap on the keyboard. I have to press the power button on the mac mini to get it to start,
I have a grey screen, with the icons still visible and a power up indicator. It takes about 10 seconds to get the screen back to normal.
I have plenty of free space in memory 966.09 free of 999.35. Any idea what is causing this problem? Should I be concerned? If yes,
how do I fix it?
Mac mini OS X 10.9.5 processor 2.3 GHz Intel Core i7
Memory 4 GB 1600MHz DDR3
Thanks, Richard

Hey 8149,
Based on your description of the waking sequence when this happens (grey screen, power up indicator, can't wake from keyboard), it sounds like your Mac mini is entering Safe Sleep, which can be perfectly normal if the machine has been idle for a while. You may find the information in the following article helpful:

Mac mini display problems

My Mac mini (bought in early 2011) has recently started having sync problems with my viewsonic monitor. It used to work fine. Have upgraded to mountain lion and mavericks hoping to solve the problem but it persists. I get snow and then blank screen. This happens randomly I never know when the screen is going to go white on me.

What connection configuration are you using...?
HDMI to HDMI
HDMI to DVI
Mini DisplayPort to HDMI
Mini DisplayPort to DVI
Mini DisplayPort to VGA
Have to tried resetting the NVRAM...? see > About NVRAM and PRAM
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.

Mac Mini Sound Issue under OS X when Boot Camp is installed

I've noticed a strange issue on my Intel Mac Mini.
Fresh install of Mac OS X 10.4.6 or higher - sound volume is normal and stays at the previously set level after a power off, power on, or just a restart.
If I take the same fresh install and install Boot Camp (confirmed on version 1.2 and 1.3 both) - and I raise the volume and restart or shut down / power back on - the volume is automatically reset to 50% when I log back into Mac OS X.
The volume problem doesn't appear to affect Windows or Linux at all, only OS X itself.
Once Boot Camp is removed, the problem goes away.
This has happened after multiple test re-installs - including with a fresh install of 10.4.x updated to 10.4.10.
Has anyone else noticed this?

sorry for digging up an old thread, but what was the problem?

2010 Mac Mini sound skipping

Have a 2010 Mac Mini Server 4 GB RAM 2.66 Ghz running OSX Server 10.6.7.
Ever since I purchased in February 2011, the machine has had skipping audio regardless of the source - You Tube or other internet streaming, local quick time movie playback, i-tunes, you name it - it ihas audio skipping and stuttering.
I also have two 2nd Gen Apple TV's that run via Home Share from this Mac Mini. There are no audio problems when the Apple TV's playback movies or music. Perfect playback.
My Mac Mini is connected to my LCD TV directly via HDMI. Have tried various different resolutions. Is this a driver problem with the Mac Mini, an interface problem with the HDMI, or what? It is a very annoying problem that ruins the Mac experience for a family that has just cast off windows completely to go Mac!
Please help!
Wondering if this could be a PAL/NTSC problem. I am an American living in Sweden and purchased the Mac Mini in the US while on vacation. The PAL 50 Mhz setting is greyed out in the display preferences. Could this be a part of the culprit?

Hey David,
My issue was resolved by ensuring that I was using a PAL resolution and frequency (720p @ 50 Hz or 1080p @ 50 Hz) for my PAL TV. Anything else causes audio stuttering through my HDMI cable.
Don't ask me why. Try this on your setup by using only the one of your TV's native resolutions and frequencies (Should say NTSC Television on every native TV resolution if you are in the US, PAL Television in Europe). If you do have an NTSC TV, then you might be able to use all of the 60 Hz frequency resolutions without HDMI audio out problems, but I wouldn't count on it.
From what I've researched on the issue, it is only TV's that have this problem, and it is a strange one, as it is actually a display setting problem with an audio error symptom.

Mac Mini Mail Problem

Hi - I recently bought a Mac Mini so that I could have a desktop and a laptop (I'd been using the Titanium G4 as both) and I have been having trouble with the email on the Mini. Right off, I should say that the G4 had 768MB of RAM whereas my Mini only has 512MB. But the Mini is 1.5 GHz versus just 800 MHz for the G4. (I clearly don't know which of those matters more in a situation like this.)
Anyway, whenever someone sends me a large file now, it takes a dog's age to get it on the Mini. And while it's clearly downloading it in the background, it seems to ignore if I delete other emails, etc. For example, I might read 10 emails and delete them, and notice that I have wait for some attachment to download, and minimize mail in the interim. When I open it again, those same emails that I deleted are in my inbox again. Occasionally, I have gone to mac.com to delete files, and eventually my mail app notices this and deletes them as well, but clearly large files are causing a problem when they're sent to me.
It's not a bandwidth issue, as my G4 handled large attachments way better with the same Internet connection, and continues to do so while wirelessly connected to it. My guess is it's the RAM, but I really don't know. Do I need to go out and double the RAM on the Mini to make this stop?

Please follow these directions to delete the Mail "sandbox" folders. In OS X 10.9 there are two sandboxes, while in 10.8 there is only one. If you're running a version older than 10.8, this comment isn't applicable.
Back up all data.
Triple-click anywhere in the line below on this page to select it:
~/Library/Containers/com.apple.mail
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
Log out and log back in. Launch Mail and test. If the problem is resolved, you may have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Repeat with this line:
~/Library/Containers/com.apple.MailServiceAgent
Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.

New Mac Mini USB problem

I have a brand new Mac Mini (December, 2011, 10.7.2) as well as an older Mac Mini (circa 2005, 10.6.4).
I bought a new GearHead USB wireless mouse to go with the new mini.
The mouse works fine on the old Mini (and also on a Windows PC).
On the new Mini, the mouse works until the Mini hibernates or powers down. On wake-up, the mouse doesn't work until I unplug and replug the USB transmitter. This is the case on all USB ports on the Mini, as well as on the keyboard and monitor USB ports. It doesn't matter which port I use or which port I unplug and replug into - I always need to unplug and replug the transmitter to get it to work after power- or hibernate-cycle.
Note that I have also tried a Logitech USB wireless mouse and an Apple Bluetooth mouse and they both work fine on both the new Mini and the old Mini.
The problem is only occurs between the Gearhead brand USB mouse and New Mac Mini (10.7.2).
I assume that the problem is that the mini is powering down the USB port and not refreshing it after power cycle, until I unplug and replug the transmitter. Alternatively, I suppose, the transmitter could be asserting itself early in the boot process before the Mini is awake enough to hear it. In either case, it seems that the band-aid fix is a command-line to force the OS to refresh the ports, but I can't find any reference to such a command.
Thank you for any help you can provide.

Hello,
I assume that the problem is that the mini is powering down the USB port and not refreshing it after power cycle,
To me it seems like when the usb is powered down the trnasmitter loses the signal with the mouse, i think your mini is perfectly fine, even though the mouse works fine on the old mini I think its how the transmitter handshakes with the new mouse on the new mac mini. Do you have a new mouse of the same brand that you can test and see if it has the same issue...
If so then it forsure the transmitter... not the mini... else take your mini in for health check.
good luck, let me know how u go...

Strange mac mini sound issue with HDMI cable

I connected my mac mini to my Panasonic 44 inch HDTV with a DVI to HDMI adapter. I didin't get sound through the cable like i expected. Then I connected a 3mm to RCA jacks adapter to the analog HDMI port on the TV and still no sound. Strangely, when i switched resolutions from 1920 X 1080 to 1200 X 720 the sound started working through the audio ports. It works on every resolution except 1920 X 1080. Any ideas why this is so? Or how to fix it?

First off, the DVI standard makes no provision for carrying sound. That is why you didn't hear any sound when making a DVI-to-HDMI connection from your mini to your TV through the adapter. I am assuming there must be a setting on your TV that is snuffing the sound input from the mini rather than the mini not outputing sound at 1920x1080. This would be easy to prove. Just pull the audio minijack connector from the mini's sound out and I'm guessing you will hear sound coming from the mini's speaker.
Is it possible that, on your TV set, you have associated 1920x1080 with an expectation of HDMI input? Maybe the TV is expecting to find digital audio over the HDMI input and somehow that association is only with that one resolution. Then when you drop resolutions it is looking for sound over the analog port instead of over the HDMI port. I'm just guessing here, but it's something you can check.

Mac mini Overscan problem

Hello, i just purchased a Mac mini and have connected it with DVI to HDMI onto my Panasonic plasma TV. The problem with this was if i turn overscan on the display is too big and is extended over the sides and some area isn't visble to me. If i turn overscan off there are black areas which is not covered around the sides of the screen. I have never had this with my PC connecting to this TV with HDMI DVI. But for some reason this problem is happneing to me right now...is there a Mac special software that can adjust the screen size so i can stretch the display around to manipulate it to a full screen size without anything being cut out or under cut in my display?

When you connected the PC and had no trouble with overscan, is there a way to capture the details of the timing involved? Because if you apply the same settings from the mini, there is no reason the TV shouldn't react to timing in the same way, meaning no overscan.

Mac mini sound

About two weeks ago I noticed that no sound is coming from my Mac Mini. When I plug in a set of headphones, the sound is fine and streaming to my Apple Tv; again fine. I have read the forums, I have done a 'clean install' of ML to no avail. Before i trapse down to my nearest Apple Store (35 miles!) anything else I could do?

UPDATE:
Took the Mac Mini to the local Apple Store. The first thing they did was a Apple Hardware Test. I hada nagging feeling that I should have done this myself but I was too lazy!
Anyway, the HWT came back with all systems ok. And the sound was now working!
Anyway, I told the friendly Apple guy (my wife at this point was drooling at his good looks!) that my system was slow with regularly 'spinning beach balls' and Spotlight indexing. My system is only 6 months old!
Without hesitation, he said this should not be the case and recommended a hard drive replacement...under warranty.
3 days later I get an e-mail stating my machine is ready and here I am, writing this on my healthy Mac Mini!
So...conclusion...do a Apple Hardware Test!
