Sound on receiver drops to internal Mac Mini speaker shutting down the TV..

Hi all,
Here 's my setup:
Mac Mini connected to the Yamaha RXV-2600 (AV-receiver) over HDMI connected to a Panasonic plasma over HDMI.
When playing music over the AV Receiver everything works like a charm until I switch off the TV, then the sound over the receiver drops dead and all I get is the internal Mac Mini speaker sound???
My STB has the same connections (using HDMI input on the Yamaha an also HDMI out to the TV) but does not suffer from this usability blunder.
Does anybody have a solution?

Are you serious?
You are suggesting another hardware workaround for something which should be taken into account by the mini' s drivers?
A 1.5 $ toslink adapter can do the trick for me just as well.
It is just my point that I wanted to avoid all this and waited for the hdmi enabled mini.
If I had bought the previous it would have saved me 300 €.
It is an Apple stupidity, even my cheap STB knows how to do it right.
Sorry for the tone in my reply, I appreciate the help, but I am getting more and more frustrated by this device that in terms of performance can't compete with my old XBMC enabled XBox of €50.
I wonder whether someone from Apple actually reads these issues, and whether they are doing something about it...
The Mac mini is a computer, a computer is designed and expected to be used with a dedicated monitor which is not going to disappear from the computers perception. There is a scenario whereby a computer monitor is shared between multiple computers which is via a keyboard/video/mouse switch. These KVM devices have been specifically designed for this purpose and avoid this sort of problem by sending a signal to the computer +even when+ the KVM is switched so the monitor is displaying a different computer.
As far as I have seen, typical AV Receivers do not send a signal in the same scenario to non-displaying devices and hence in this case the Mac mini perceives a loss of signal. The Gefen device therefore gets round this problem.
With regards to set-top boxes and similar devices, they are not computers and have therefore been specifically designed (differently) to accommodate this situation.
I agree it would be more preferable for Apple to make the Mac do this sort of thing automatically itself, but such a use is not the normal one for a computer so it is somewhat harsh to try and blame Apple.

  • Mac Mini auto shuts down shortly after startup chime...what should I do? Thanks.

    Our boss brought a mac mini model A1176 from the US to be used by her staff here in the Philippines. We powered it up- everything was working. Then it just stopped working after onen day. Whenever it is powered up, the mac mini auto shuts down shortly after the startup chime. What's wrong. How can we fix it? Thanks a lot.

  • Mac mini keeps shutting down for no reason

    My mac mini keeps shutting down for no reason. If I try to turn it on right after it shuts down, it won't or I may hear a chine, power light lit up for about 5 seconds and turns off. I have to wait a while before it would turn on again. And sometimes it stays on for 15 min, 2 hrs or 1 full night ... but then the cycle happens again.

    Make sure the power cord is attached firmly to the back of the Mini. If so, try a clean install of Snow Leopard (or whatever version of OS X it came with). If neither of those suggestions works, it's likely a bad power supply, in which case you'll need to take it to an Apple store or call Apple support.

  • Mac mini intel shut down problem !! please help !!

    hi !
    following problem, mac mini intel single core does not shut down, shut down process last 10 min and more (bluescreen, black wheel running) but does not shutdown at all!!
    When I log off my user and then press the shutdown button at the login window, it shuts down normally.
    Any ideas???
    Feeling like being in windows times???
    please help
    thanks

    Good catch. I would never have though of that since I eagerly anticipate each chance I get for a clean install.
    I much prefer to get a clean start and consciously change the things I need to work - often I find that the defaults really are better and would otherwise be stuck in habit...

    Intel-based Macs: Resetting the System Management Controller (SMC)

  • Mac Mini Server Shuts down every 14 days for no apparent reason.

    Just before 8 AM every other saturday morning, I have a Mac Mini Server running 10.8.5 server that powers off. There is no indication of anything out of the ordinary happening prior to the shutdown. On restart the server continues to operate properly for another two weeks until it shuts down again. The only log entry I'm seeing that seems to indicate what might be going on is:
    Dec  7 22:51:29 localhost kernel[0]: Previous Shutdown Cause: 3
    This past weekend I attempted to get around the issue by having the system set to automatically turn on or wake at 11 AM, but that did not happen.
    I've checked cron and launchd and nothing is scheduled around that time.
    Any ideas?

    Yes, a glitch with any less-interruptable power supply — they're never truely uninterruptable — could well trigger this outage. 
    If you're willing to run with grid power for two weeks plus a day, then cable the APC out of the path, and see if your uptime makes it to fifteen.   
    Probably much quicker and if you've got some off time where you can quiesce most of the activity on the Mac to allow it to crash hard with less risk to your data and your processing, then pull the input to the APC and see if the Mac crashes.
    Various APC units run a self-test every two weeks, so a problem with the self-test or the switch-over or with he battery could well cause the reported problems.  Could also be the quality of the power being generated (I'm running Smart-UPS units because of that) or the APC is overloaded, but I wouldn't expect that to occur on a particular schedule. 
    This reeks of the self-test or the power relay, or the battery.
    Some semi-related discussions here, and probably elsewhere on the net.

  • Why does mac mini power shut down when trying to use external harddrive as boot drive?

    I connected a OWC Mercy Elite Pro external hard drive that has it's own power source to my mac mini. It's connected by firewire and I'm trying to use it as an external boot drive. The problem is when I have the power turned on the OWC before I turn the power on the mac mini, the mac powers up but then shuts down after about 30 seconds. However, if I wait to turn on the OWC power after the mac boots up there is no issue. Of course this defeats the purpose of using the OWC as a boot drive because it needs to be on before the mac boots up. I don't have any issues using another external hard drive as a boot drive that doesn't have a power source.

    Hmmm, very strange, could there be a ground loop where the OWC drive is plugged in?
    If you hold alt or option key at bootup, without the OWC drive, once the boot manager shows up connect the OWC drive, wait, does the OWC drive show up eventually as a boot choice, or what happens?

  • Mac Mini G4 shuts down during boot-up

    Hi All,
    Just upgraded a G4 Mac Mini to Leopard, all was going fine until today. I just ran software update to install the very latest Security Update along with MobileMe and now the following happens: the machine starts to boot up as normal - grey screen, dark grey apple, progress spinner for about 30 seconds, then the whole thing just shuts down. Happens every time now.
    I haven't yet had chance to boot from the Leopard DVD but are there any smart bods out there with a similar experience who can give me a clue as to what's happened...? I've just spent the last 24 hours getting Leopard and various bits of software installed!
    Thanks!

    Sorry to hear about the loss of the iTunes library, though if you had another Mac available you might find the files are recoverable by getting the mini into firewire target disk mode. If Disk Utility found difficulty with the catalog rather than widespread data corruption, much of the data on the drive may be recoverable despite DU's inability to effect a repair.
    I think you are right however to go the erase and install route to get the system back into service. Utilities such as Tech Tools and Disk Warrior can often effect repairs, but there is nothing as good as a reformat and reinstall in terms of reliability, and creating confidence in the system's on-going use.

  • My mac mini wont shut down when i try it does restard instead and said it has recovery from a problem. How can i sort this out?

  • Mac Mini "unexpectedly shutting down"

    Within the last week, my mini (less than two months old) has started suddenly posting a screen (black with grey/white writing), stating that it is has unexpectedly shut down after being on for about 20 minutes. I am instructed to hold down the power button and restart. The problem occurs when I am in different programs and when I looked at the report that was generated it was a kernel error. Any ideas of what the problem is or how to fix it? If the message comes up again (it hasn't the past two times), then I will copy it and post it here.
    TIA-
    Campbell

    The problem with diagnosing this issue is that it's neither clear what was wrong with the system when it was repaired, nor what was done to resolve it at the time. While these events may have nothing to do with the present issue, they may be directly related.
    As an example - you say that the system was not hot when it recently shut itself down, but had the repair involved removal of the logic board and the thermal pad wasn't replaced (as described as a requirement in the service notes) then it would render the system far more likely to apparently random shutdowns, because heat would build up more quickly and trigger protective mode with little apparent heating. That would also explain why the restart options don't seem to work.
    Thus it might be a good idea to ask the repairers exactly what they did to the system when they had it, before contemplating a potential fault in the power unit.

  • Mac mini doesn't boot the first time i turn it on

    hello,
    i have a strange problem with my mac mini and was wondering if anyone had heard of it before.
    when i turn on mac mac, the light comes on and i hear drive noise, but no chime. no video is sent to the display (the monitor flashes "no signal"). however, if i wait for 5 or 10 minutes, turn it off by holding down the power button and then turn it straight back on it again, it starts up as usual (with chime).
    could this be a software problem or is it more likely a glitch in the hardware?
    mac mini, 1.66ghz intel
    mac os x 10.4.11
    cheers,
    jack.

    That doesn't sound like a software/OS problem, because MacOS doesn't begin to load until after the initial startup, including the chime and the grey screen with Apple logo. Since you don't get the chime or display, it sounds like the system has a hardware problem, or perhaps an issue with PRAM.
    As a first step I would reset PRAM as follows:
    -Shut down the computer.
    -Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in the next step but one.
    -Turn on the computer.
    -Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    -Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    -Release the keys.

  • Sound out reverts to internal speakers at every shut down

    Everytime I turn on my Mac Pro I have to go to System Preferences and change the sound to Line out. Every time I shut down the sound out defaults to the internal speakers. is there anyway to stop this?

    Things you can try.
    1. Smc and pram resets.
    2. See if you can get it to "stick" by setting the sound out preference with Audio MIDI Setup (in your Utilitiles folder).
    3. Last resort -- temporarily remove the two plists in /Library/Preferences/Audio.

  • Mac Mini and ipads for the family

    In the near future, I would like to replace my older PowerPC G5 with a Mac Mini. Then, I would like to purchase a couple of ipads for my wife and two kids, who primarily use the G5 for email, web surfing, and light-duty work such as organizing (ical), filing documents, and using spreadsheets/word processing software, with occasional photo-editing. Essentially, we would set up accounts for each user on the Mac Mini where all of the files/photos/organizing would be stored, and then just tap into them via housefhold wifi with the ipads as needed. Any major computing could still be done directly on the Mini (and I also have a newer MacBook), as needed. An added bonus would be that we would also use the Mini as our household media hub for streaming music to entertainment center and video/movies to the TV. I really like this scenario, as it would allow for greater flexibility and portability, while still serving the needs of the family. I think this can be easily done, and suspect the experience could be enhanced by a few apps, but I haven't researched that end of things yet. First, I wanted to ask the folks here if this is a realistic plan? Also, would I be better off with the Mac Mini or Mac Mini Server? Any and all input is welcome, as well as helpful suggestions from those who have already done this. Thanks in advance!

    It sounds realistic, I haven't done it though, & I don't think there'll be much diff between the Server & Client models for what you want to do.

  • Mac mini can not find the NAS

    In my network I have a Mac mini, AirPort Extreme base station and a Netgear ReadyNAS Duo v2. Everything is connected by cable. The problem is that the Mac mini can not find the NAS. Mac mini is looking for wirelessly connected devices, type TimeCapsule. How do I get my Mac mini to find the NAS and set the NAS as a source of data storage?

    I have a ReadyNAS and use it as a Time Machine destination with no problems, even over WiFi. The ReadyNAS and Mac are both on the same LAN (even though the Mac is on WiFi), please check to see if your WiFi is on a different LAN to the Ethernet side of things, I have my Airport set to bridging mode so both sides of the AirPort count as the same LAN.
    Next you need to check you have actually configured Time Machine in the ReadyNAS, as shipped it is initially turned off. You need to go to the ReadyNAS web management interface (FrontView) and then click on Backup on the left, and then select Time Machine. You also need to make sure Bonjour is enabled for the ReadyNAS, this is accessed by clicking on Services on the left and then selecting Discovery Services, make sure all the Bonjour options are ticked on.
