Poor audio quality on new mac mini

I getting lots of audio interference when headphones are plugged into mini headphone jack.   Interference varies with where I'm standing in my room.
Mac mimi is new.

Are you using wireless headphones? Or is it a cabled one? Are you hearing the noises when listening to the internal speaker?

  • Anyone having Audio Issues with new Mac Mini, new Thunderbolt Display and new Pegasus R4?

    I can't listen to the built-in speakers on my brand new Apple thunderbolt monitor to the terrible audio quality.  I'm running Mac Lion on a new Mac Mini with a brand new Promise Pegasus R4 - all purchased in January 2012.   The entire setup is connected via Thunderbust errh, I mean Thunderbolt. 

    Hi,
    I'm also having an audio problem, which I suspect now is caused by my Thunderbolt display.
    See https://discussions.apple.com/message/21499606#21499606 for the small thread.

  • Poor WiFi performance on new Mac Mini ?

    My new mac mini purchased a few days ago (late 2009) was exhibiting abysmal WiFi performance on 802.11n 5Ghz. I was barely getting 1Mbyte/sec through it, despite good signal strength (-50db), and my iMac which is feet away on -58db is giving almost 18Mbyte/sec...
    Anyway - after much gnashing of teeth, and even placing the mini next to my extreme basestation I gave up, then tried, out of desperation, resetting the PRAM... Fixed!
    Why on earth a brand new machine should need this doing, I'm not sure, but the old Alt-Cmd-P-R at boot up, waiting for the second BONG, and then letting it continue, fixed everything, and it now zooms along as fast as my other Macs.
    Just for info - hope it helps someone!

    These are pings from my iMac to .02 (mbpro) and .11 macmini
    the mbpro is sat right next to the mac mini... rebooting the mini sorts this out... Come on, somebody must have this problem as well?

  • New Mac Mini and TrueHD audio

    Has any one know if it's possible to play back uncompressed audio streams from .m2ts streams thru the HDMI connector, or are the Dolby Digital and/or DTS the only streams that can play back thru HDMI?

    Apple have only said Dolby DTS works, and PCM works. They have not mentioned TrueHD. However others have said that currently the chips used in the Mac mini do not support sending True HD via the HDMI, even though the HDMI specification obviously allows this.
    The conclusion is that we would have to wait for another newer Mac mini model with a better set of chips.
    I have seen less to nothing about the possibility of running TrueHD via the Mini Displayport and then an adapter to HDMI. It is the case that the Mini Displayport supports audio on the 2010 Mac mini but it is likely the same chip issue prevents True HD.
    This is all very disappointing of course.
    For the moment, I am sticking with an Apple TV running XBMC which is far cheaper but still does not support TrueHD.
    PS. If the rumours are that the next Apple TV only does 720p are true, then Microsoft will (rightly) be laughing at Apple's feeble efforts.

  • New Mac Mini sends airplay audio but does not receive it

    I just purchased and set up two new Mac Minis with Mountain Lion. Previous to this, using Lion and even Leopard, I could send Airplay audio to any of my desktop machines. Further, my iOS devices could send audio to my Macs running Snow Leopard and Lion. The new machines do not receive airplay audio from anything. They can send to the other devices, but not to themselves. Had I upgraded all of desktop machines to 10.8, I wouldn't be able to send audio anywhere.
    Why is this?

    From what I'm reading, airplay is only for streaming to your tv.  I have apple tv and have never been able to stream from one device to another;  only from device to tv.
    Can you link to an apple document saying it's supposed to work computer to computer?  Are you sure you weren't using home sharing in itunes?

  • 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.

  • Does anybody know if the new mac mini introduced today will do hd audio bitstream?

    I'm very interested in the new mac mini that has been unveiled today. I planned to buy one in the past but didn't because it seems that it couldn't do bitstreaming for hd audio (true-hd and dts-hd for example).
    As I plan to use it as an htpc with xmbc so this is a feature that is important for me. For what I heard, the last generation of mac mini couldn't not because of the hardware but of a driver issue in mac os x. So I was wondering if that still the case.
    Thanks!

    The previous model supported multi-channel audio via the HDMI but did not officially support HD audio.
    However I seem to recall that XBMC for Mac had already managed to do this on the previous model Mac mini. For clarification since XBMC for Mac managed to do this it would appear the hardware already could do this but Apple have not provided built-in software support for this.
    See http://forums.plexapp.com/index.php/topic/42798-hd-audio-codec-support/
    I could not find a similar statement saying Plex itself supports HD Audio bit-streaming via HDMI.
    With regards to the new Mac mini I do not expect there to be any change. That is OS X itself will not support this, Plex will still not support this but I would still expect XBMC for Mac to support this.
    PS. The MacBluRayPlayer I feel also does not support this.

  • Quality issues with new Mac Mini 09?

    I've been itching to hit the 'buy' button -- but in reading the many postings about the new Mac Mini, I'm seeing lots of issues with the bluetooth ... *wireless signal* ...
    Is there anyone who's not experiencing any problems?
    Sounds like it may be a hardware issue with connections... the last thing I want.
    My other choice is the 2008 Mac Pro which seems trouble free.
    What do you think?
    Thanks.

    There is a general issue/trend with the new Mini. There are plenty of reports in these forums and the news has begun to hit the wider press; I guess this is more important to a company with only 2-3% desktop share than posts to these forums. I went to the Genius Bar on Saturday and they have now lodged an official bug report with Apple. It looks like the Mini cannot pair with more than one HCI device. So if you pair with the mouse first the keyboard won't work and vice-versa. They don't think the Mini hardware is broken but that we will just have to wait for Apple to fix the firmware.
    Where I do agree is that some issues are OS-X 10.5 related and can therefore affect all Macs. The WiFi has issues where it randomly drops, it doesn't seem able to re-connect at all to channels above 13 and only manually to channels below 12. The system resume function is unreliable. All these started when we moved from 10.4 to 10.5 and so far they have not been addressed. One issue is that there does not appear to be a way for users to log bug reports, except when software crashes. However, the bluetooth issues on the Mac do appear real and are either firmware or hardware related.

  • Using ADC Monitor with the new Mac Mini

    My husband has an Apple monitor with an ADC connection. I would like to purchase the new Mac Mini, but would like to use his current monitor. I know there is an ADC to DVI adapter, but the new Mac Mini uses the Mini Display...could I use yet another adapter? I am trying to save money, but don't want to the display quality to be really poor. Space is not an issue. Any help would be greatly appreciated.

    I have located that, but my concern is the DVI connection to the Mini Display connection on the Mac Mini. My understanding is that they are different.

  • HDMI to TV as Display for New Mac Mini DOESN'T WORK

    I bought a new Mac Mini and was told I could us HDMI to my TV as display.   I was using this TV as display for older Mac Mini (VGA) and for a Windows PC, and DVD via HDMI.     TV is one year old. 
    The Genius at the store who sold me the new mini said all I needed was an HDMI cable.   Which I purchased. 
    The screen comes up for the Setup Assistant but as soon I select continue is goes to gray, mixed color scanning garbage mode.    If I turn the TV off and back on, the screen returns (now at the next prompt in the setup assistant) but again it goes gray after hitting continue.    Unusable, CANNOT set up my new purchase.
    Unfortunately, the DVI to VGA adapter on my old mini is different and doesn't mate to the HDMI to DVI adapter that ships with new MacMini, so I can't test VGA.   The old DVI to VGA has extra pins not on the new one. 
    My purchase is not usable and is extremely poor.   Buyer beware I guess.   

    I have been using MacMini's for commercial digital signage/video conferencing gateway usage for sometime now, they all have HDMI output, about one third are on Lion the others still on Snow Leopard, here's what I have found.
    Toshiba & LG tv's are generally reliable, Samsung and Philips generally are not, Panasonic, Sony, Sharp & Viewsonic all work, somtimes with a bit of work from me.
    Cables are important (always look for compatibility with HDMI  revision 1.3 or greater (1.4 preferred), don't waste your money on exotic brands, adhere to the distance limitations, I generally send the HDMI signal wirelessly (cost of labor to add wiring to an existing space can be very high) so am limited to less than 50ft, same as with a wire.
    READ THE TV MANUAL, find out what HDMI choices your tv possesses, is there a 'parallel' audio input available for the times when your signal origin is a MDP or DVI.
    Some TV's just don't work well, cut your losses and get another when faced with this issue.

  • New Mac Mini and Repairing Permissions

    I've been having trouble with my Mail program and thought I would repair permissions to see if that would help. I ran disk utility from my internal hard drive and ran repair permissions. Apparently it found several permissions to repair, so I thought I would run repair permissions again and the same list appeared. Running a third time and the same list appeared again.Do these permissions ever get repaired? What do I do from here? Should I repair permissions after booting up off of my original system disk? This Mini is only a couple of weeks old and I'm already having problems with Mail and repairing permissions.
    rskover

    Thank you Tim but the computer is packed back waiting for TNT to take it back to Apple. I don't have time to play with permissions, the permissions are OK in the old computer.
    This is what may have been your problem. The permissions on your old computer may not have matched the new computer. I think you gave up before the penny dropped.
    They sell the computers very expensive and I think they would have to improve quality.
    I am unsure how that can be one of your gripes as when the cube came out it was way overpriced in comparison to their other desktops. That did not stop your or I getting one then.
    Your issue was a software problem not a hardware problem so no matter what kind of mac you had it would have needed troubleshooting.
    The quality of the new mac mini far exceeds that of the cube. Try playing 1080P high definition media on your cube, or even 480P for that matter. Try outputting 5.1 surround sound from your cube without the addition of a firewire audio interface.
    I know how frustrating it can be when something just does not seem to work. I have encountered this a few times in my work. However sometimes I just have leave it come back with fresh eyes and try other approaches and I succeed.
    What you need to appreciate installing an upgrade should be planned for any eventuality. In business upgrades are scheduled to have the minimum impact on the workplace. That being said I have worked 48 hrs solid over a weekend getting systems up for a monday morning. They are not always straightforward.

  • NEW Mac Mini i7 SUPER SLOW

    I have been surfing the discussions for a while, and can not find a reason why. I have been using mac for about 10 years now, and I can not figure out why my new mac mini with the i7 chip is running deadly slow. I dont download anything that isnt on the iTunes library or the App store. It has loads of storage left.
    Here are my specs:
    OSx v 10.9.4
    Proc: 2.3 GHz Intel Core i7
    Mem: 4GB 1600 MHz DDR3
    I have 600GB left of storage
    When I boot the computer it boots really slow. Like 4 or 5 minutes from the time i press the power button until I can log in.
    After logging in, if I click to open a program I can literally sit 4 or 5 minutes before its open.
    It has done this since I opened the box and fired it up for the first time.
    Are mac mini's normally this poor of performance? It drives us nuts as our old iMac was WAY faster than this and it was nowhere near as "powerful" of a computer.
    If someone out there can explain what I can do I would sure appreciate any help.

  • New Mac Mini... airport problems

    Hi, I have a problem with the wireless connection of my new mac mini (Intel Core 2 Duo 1.83GHz)... it's very slow and the signal strength is always up and down... what to do? I also have an iBook and a PC connected at the same router and they're working fine. Should I wait for a firmware upgrade or should I contact Apple for support? Thanks

    +I think I placed the mini in the best place+
    OK, but since it's not working for you, it might still be useful to know how everything is arranged, distances between computers and router, and anything between mini and router. And presence of nearby 2.4GHz cordless phones.
    To quote AndyO:
    "The real problem is that unlike almost every other problem in system troubleshooting where symptoms can help one refine the possible causes until only one is left, variable wifi is something that is very difficult to deal with at a distance because there are many, many factors which can impact the quality and level of signal, and _much can hinge on small details that often get overlooked_.
    "It should be noted however that the general consensus has typically been that Mac minis suffer poorer wifi reception than other systems, in part one suspects as a result of the antenna being up in the top-right corner of the enclosure where it is in part screened by the casing. Thus, make sure there is nothing directly above the mini itself, or immediately to the side of it which might hinder signal."

  • New Mac Mini 2012 - HDMI dolby surround

    Hi,
    I returned my Mac Mini 2011 because of the poor (lack of) dolby surround support outside of Apple iTunes.
    I am very interested to know if somebody can confirm the new Mac Mini 2012 has better dolby surround support. I would like to connect the Mac Mini to my dolby surround receiver with plug and play support in Mac OS X Mountain Lion. And of course compatibility with media software (e.g. VLC or other players).
    Thanks for your comments!

    The Mini will pass through Dolby and DTS encoded tracks to
    any device which can decode it with XBMC, PLEX, VLC,
    MplayerX, etc.
    The signals can be passed through via HDMI or optically.
    The proper set up is required in the Audio Midi Setup utility
    and in the app.  If you are expecting decoding within the
    Mini to multichannel PCM, I don not believe any apps are available
    to do that (or I am just not aware of them).
    If your are expecting the higher level encodings (DTS-MA or Dolby
    True HD), at least up to the 2011 models, they do not contain the
    required "protected audio path" to support those formats.

  • New Mac Mini and Analog TV

    I just bought a new March 2009 Mac Mini. I am trying to hook it up to and old analog TV. The TV has SVIDEO and RCA jacks. I purchased the Apple Mini-DVI to Video Adapter only to find out it will not work with the new model. It seems the new model only outputs DVI-D and not DVI-I.
    I am trying to hook up the mini-dvi to SVIDEO on the back of my TV and then for the audio connect them to the TV with RCA jacks. Is there any way to get the new mac mini to work with an analog TV?
    Thanks

    When you cite "VGA converter to RCA" do you mean a little box that actually converts the signal down to RCA/composite, like this:
    http://www.monoprice.com/products/product.asp?cid=101&cp_id=10114&cs_id=1011407&pid=4724&seq=1&format=2
    or simply an adaptor like this one:
    http://www.monoprice.com/products/product.asp?cid=104&cp_id=10401&cs_id=1040113&pid=2509&seq=1&format=2
    The crucial thing I'm waiting to find out is whether the new Minis provide ANY analog video signal to either of the video ports at all (which would seem to be the case, since VGA is analog, right?), or if the analog roadblock is simply caused by the currently available adaptors.

Maybe you are looking for
