Mac mini audio resets to 44.1khz after boot

Hi, I use my Mac mini with EyeTV sat and the best performance is reached by setting the audio out to 48khz. Now this is easy done with the midi program but I find it annoying that after a reboot the audio resets to 44.1khz. I searched for programs that might do this reset to 44.1khz but could not find one. Does anyone have an idea how to keep the audio out on 48khz?

Hello Star1,
I absolutely agree that there is no difference that I could hear but video or tv seems to come with 48khz audio. At least EyeTV for my satellite television needs much more processor power and starts to stutter when the audio is not 48khz. This is a known thing with EyeTV, I'm not sure if it not just bad syncing or bad programming but I have to accept it Anyhow perhaps it is an OSX question?

Mac Mini (Core Solo 1.5GHz) won't boot. Any ideas?

My Mac Mini is hanging when I try to boot up (just sits at the grey apple screen and the progress wheel just cycles indefinitely). I've tried booting into single user mode and running fsck and the disk is fine. If I try booting in verbose mode it seems to hang with an error pertaining to the AirPort card.
I've mounted it in target mode and backed up /Library and /Users in case a nuke&pave is required and have grabbed a copy of system.log to get the error messages. Here's the entire boot sequence up to the point where it hangs:

Anyone got any ideas how I can try to fix the problem? I don't actually use the AirPort card as it's wired into my router so if there's any way I can disable it that might be useful.
In the case of a nuke&pave is there anything else I should back up besides /Library and /Users?

Fixed it!
I mounted it in target mode again and manually applied the 10.5.4 combo updater ad it now boots again.

Internal HD on mac mini not well... need to boot in Single User Mode

Internal HD on mac mini not well... need to boot in Single User Mode.
I only have a Bluetooth Keyboard and Bluetooth Mouse so when I try to boot in Single User Mode (to do the /sbin/fsck hard drive fix thing) it doesn't see the Bluetooth Keyboard. What's the solution?
I also used SuperDuper to use as a boot drive but it won't unmount my internal HD. arghh..
Help

I have a corrupt drive and was unable to repair all the errors after booting from OS X installer disk and choosing Disk Utility...
I followed the "boot into single user mode" instructions hoping to complete my repair with fsck, however once I got to the localhost:/ root# prompt, my keyboard seemed to be unrecognized!
I tried 3 different USB keyboards - original Apple USB keyboard, Kensington Mac USB keyboard and an old SGI USB windows keyboard. All were able to enter the apple-S key to get into single user mode but NONE of them were able to type any commands whatsoever.....
I'm thinking my only option is to boot the mini as a target drive off my laptop and try to backup my 30GB of music and photos before wiping the drive...
2nd option might be to try Disk Warrior for $79??
Anyone else have ideas for me?

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 (Mid-2011 Core i7) Slow after Yosemite Upgrade

I've searched the other "slow after Yosemite upgrade" threads but those seem to relate to Core Duo 2 machines with less RAM. I have a Core i7 MM w/ 8GB of RAM, after the Yosemite upgrade it constantly lags, I can barely type on it these days because the text lags so badly. It's unusable to say the least. Is there anything I can do to speed it up? There must be a reason why the performance is so bad.

Slow after Yosemite upgrade.

Have downloaded Mountain Lion on my 2010 Mac Mini. Now when starting up, after a while I get a message that says, "You must restart your computer." I do that but get the same message again and again. Any ideas? Thanks!

I am having issues trying to start up with Mountain Lion on my 2010 Mac Mini. Here's the scenario:
1) After starting up, I get the usual gray screen with Apple logo.
2) After a few minutes, a darker gray screen scrolls down and in the middle of this is a black dialogue box with reversed (white) text. This text, in multiple languages, reads: "You need to restart your computer." Then it goes on to instruct on how to shut it down and restart it.
3) I follow this instruction, but get the same dialogue box over and over agin.
Any ideas?
Thanks and best wishes.

If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Safe mode is slower than normal, and some things won’t work at all. Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the startup volume is on a software RAID, you can’t boot in safe mode. If you're able to boot, launch the Console application in any of the following ways: ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. ☞ Open LaunchPad. Click Utilities, then Console in the icon grid. Select the most recent panic log under System Diagnostic Reports. Post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.

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 audio probelms

Hi guys I'm having trouble with a intel CD Mac mini. For no apparent reason it's decided to think there are no sound devices. I've never seen this kind of thing before and I'm hoping that it isn't a hardware fault 'cause as far as I know the audio is integrated onto the motherboard.
I already did a backup and fresh install. didn't solve the problem. That's what is making me think hardware issue.
I did add some new ram about 5 or 6 months ago but this only happened recently. Also did a hardware test with the restore cd utility and found no problems or faults.
specs are: Mac Mini | Intel CD 1.83 GHz, 1.25GB RAM, 80GB HDD, Mac OS 10.4.11
Ill put up some more info when I can.

Xavier,
If your system profiler does not list "Intel High Definition Audio" and instead says no audio device detected - then you might just need to have someone carefully open the mini and reattach the ribbon cable. It has to be removed to upgrade RAM or the HD - and I had my mini at a very good tech, but it came loose after 5 months. I was moving the mini the other day and perhaps jostled it, but it does want to pop up over time.
Someone that works on macs should have a nice tool to open the mini and it really takes 5 minutes total to reconnect that cable and put it back together. No parts needed...
If this doesn't fix it - you might have a failure of some component, but I was happy that reseating the cable in the connector was all that I needed...
Good luck!
Mike

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.

Thanks much for any input - it would be very much appreciated.

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

My mac mini loses connection with my receiver after turning off the receiver then back on

My Mac Mini loses connection with my Onkyo receiver NR-609 after turning off the receiver then back on. The only way to reistablish the connection is to unplug then replug the HDMI cable to the Mac Mini. There's no effect if I unplug then replug the HDMI to the receiver. Any help or suggestions would be appreciated. I've searched a lot but haven't found much of anything so if this is covered elsewhere I would greatly appreciate a link.
Thanks in advance

Hi and thanks. I don't know about the audio prefs. When it happens I am not able to see or hear anything from the computer until I un/re-plug the HDMI to the Mini. I'm not sure it's changing to something else because there's nothing else connected for it to change to. I could see that perhaps the audio will change to the Mac Mini's internal speaker.
I found out last night that if, after I lose the signal, I use my ipad to play a video on the Mac Mini using the Remote app and home sharing the signal gets righted and I can see/hear the computer again. It's quite an inconvenient fix though and I wish and hope someone here can help me.

Mac -Mini running at 100C CPU temperature after receiving back from servic

Hello,
I just received back my Mac-mini from Apple service.
As other users reported, the fan was going mad, running at full speed all the time. By using: http://www.bresink.de/osx/TemperatureMonitor.html
I could see that the temperature-sensor connected to the heat-sink did not show up in the list of sensors. Service replaced the main board, and now the heat-sink sensor shows reasonable readings, and the fan is running silent, at least with no work load.
However, while performing a little web browsing, I found that the fan still goes wild.
What I noticed: The "TemperatureMonitor" utility reports that the CPU core temperature goes up beyond 100C/212F, even under mild work load, while the CPU heat sink is still reported at moderate temperatures around 35 C/95F !??? Environment temperature is below 30C.
Before I give away my MAC for another week or two, I would like to check whether this is usual behavior. Other users report max CPU temp of about 80-90C. Intel specifies max core temperature of 100C. According to the digital thermometer build in, my MAC sometimes exceeds this max spec by Intel.
Is this usual behavior, or did Apple service not properly install the heat sink after service, such that the CPU is only running with limited cooling ??
Thank you for your suggestions

Only an internal investigation would show whether the heatsink was correctly reinstalled, but quite clearly since the temperature being reported is at the operational limit specified for the processor, what you are experiencing is not in any way 'usual'. There are sites with content such as flash animations, which can cause high CPU load and thus push system temperatures up and cause the fan to spin up, but not for prolonged periods of course.
Since the fan is running up to full speed on your mini as a result of the temperature rising, it is clearly not an issue with MacOS or the fan control cable, and as such I would urge that you return your system to the service provider with a description of the problem and a list of website addresses you have visited which causes these problems so they can set about replicating the issue.

HELP... MAC MINI DISPLAY RESET!

I just got a Mac Mini for home and planned on using my LCD TV as the monitor. Not realizing that I had HDMI input on the TV, I purchased the DVI to VGA adapter. I was adjusting the Display Settings on the Mini (because the picture was terribly blurry) and the screen went blank when I changed the resolution (I was just clicking each resolution option). I was able to restart the Mini and it brought the display back up. So I tried to adjust again and the screen blacked out once more. Now, I am unable to see anything at all. I tried to reset the PRAM/SMC or whatever (I did both procedures) but I still can't get even the blurry picture back. If I unplug the DVI/VGA adapter, the screen flicks up what would be 'on screen' and blanks right back out. Is there a way to reset the display to the default?
Message was edited by: [email protected]

So, I called Apple Support today and tried all of their procedures. Finally, they told me to reinstall OSX. I reinstalled and the screen went back to old blurry. I purchased a DVI to HDMI converter, plugged everything back up and... not so blurry but still not satisfactory (even to my wife's standards, who normally doesn't know/notice/understand/care about things like that... so, it MUST be bad). I found my TV resolution in the manual, it is 1440x900 and says it is 720p. So, I tried to make adjustments again. Back to Black (I am starting to feel like JayZ). I am now reloading OSX (this time I clicked 'Options' and opted to erase the entire hard drive, then reload).
I called Apple Support back and they said that they are unable to do anything more over the phone (Dell did not buy Apple, right?). I was instructed to return the MacMini to an authorized agent to have them look at it. I guess I will do that tomorrow since I spent all of today F'ing with it.
In the mean time, if someone can help me figure this out, I would be very appreciative.
Thanks, Matt.

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 audio out

I have a mac mini. what type of connector/cable do I need to output digital audio?

Some Toslink Optical Cable Kits come with 3.5mm adapters.
If you already have an Optical cable, then all you need is a > Toslink to Mini Plug Adapter
If not, then you will need a > Toslink to Mini Toslink Optical Cable
