Continues audio hick-ups iMac Marantz SR6004

Hi,
I recently bought the Marantz SR6004 receiver which has a bluetooth receiver (rx101) for wireless audio which works great with my iPhone 3GS and Dell inspirion laptop. Today I tried to do the same thing with my iMac (early 2008).
The connection was easily set up, the iMac sees the rx101 and reads it out as a stereo audio device. When I started iTunes however I continuously had hick-ups and also the audio seemed to be faster and then halt for 0,5 second and then tries to catch up. So something must be wrong but I've looked at all the possible settings but the hick-ups were still there. I also noticed that the cpu usage is a lot higher when streaming audio, around 14% instead of 5% with peaks above the 20%.
No other applications or connections were open at the time I tried.
Other bluetooth devices run smoothly on my machine and the receiver also works well. Does anyone know how to tackle this issue?

  • How can I input stereo audio to a iMac late 2012?

    I can't wee where I can input stereo audio to my iMac (lat 2012) so that I can save the digitized audio to the music library.

    I have one of these (iMic)... Sometimes I need to get a song off of a cassette and this does the job.
    USB Audio Interface: iMic lets Mac and PC users add stereo input and output to USB computers — even computers that lack audio-in or -out ports.

  • Lost audio on my iMac with Mavericks download, any ideas?

    I've lost all audio on my iMac with the download of Mavericks, does anyone have an idea?

    I did get my audio working again, don't know for sure why exactly, but here's what I did. First of all I have my external speakers plugged into my headphone jack. I had zero sound of any type plugged in or not. First thing I did was to reinstall Mavericks - still no audio. I tried everything on the computer that said "Sound - Mute - Volume etc... computer geek I'm not. Under System Preference I went to Sound clicked everything, Under Output I clicked on headphones - It was already On, I clicked it Off then On again - all my sound came back. I'm not sure why since I had no audio sound with or without the speakers plugged into the this jack. Maybe it was a combination of things and I got lucky. Hope this helps!

  • Audio issues on iMac

    The audio of my iMac has stopped working, but earbuds ok. How do I fix it?

    This solved my problem:
    "... disconnect and reconnect your ear buds from the jack on the iMac's back panel several times ..."
    The internal speaker option wasn't available until I disconnected and reconnected earbuds from the jack several times.
    Thanks,

  • The audio on my iMac G5 suddenly quit.

    I hope you can help.  The audio on my iMac G5 suddenly quit.  Music in iTunes doesn't play, and there's no audio on
    videos from YouTube.  BUT I don't think it's a hardware issue, since the chime DOES sound when I reboot.
    I went to Preferences and Sound, and saw that there's nothing in Input, but the Mute is checked and greyed out. 
    Does anyone know how I can fix this?  I have no idea how it got muted; I didn't do anything.  And since it's
    greyed out, I have no idea how to unmute. 
    Any advice?  HELP!  Thanks!!!

  • Continuous Audio/Different Menus?

    Hi there, I was just wondering if it is possible to create a DVD in DVD Studio Pro 4 so that there is one audio asset that plays continuously while the viewer changes from one menu to another.
    I like having audio with my menus, but it is annoying to constantly hear either the same song beginning on each menu change, or to keep hearing random different songs.
    Thanks for the suggestions!

    Hi There,
    If you only have about 9 total menus on your DVD that would be good to have continuous audio under, as one navigates to the other, then you could acheive this with 'buttons on video' in a Track with 7,8,or 9 angles.
    Depending on your project and how you nest the hierarchy of the menus, you could acheive the effect of even more seamless audio menu switches.
    Yes, I have the spec books, which are very explicit that this can be done, and recently completed a massive several months long project helping an authoring studio working for a major sports league implement this exact functionality.
    Though, I had to switch them over to Scenarist, which they purchased ( I told them they'd need Scenarist at the get go, but they wanted me to test in our player bank DVD SP and Scenarist projects side by side on this and other questions regarding implementation of this functionality, before they were convinced to spend 20K!), because of DVD SP's lack of being able to define individual subtitles instances as buttons with highlight info and navigation commands; as DVD SP forces a whole complete cell for each subtitle defined as a button. But you won't need as many cells (thousands) as they did.
    So, if you really want to get it done, it is possible for certain projects. We ran multiple versions of that project for that company in all 145 of our players, and there were only a very few incompatibilities, which didn't faze them from mass releasing world-wide. Oh btw, check out the new pic on my site of a few of us around the player bank, with the list of players, if you'd like.
    But for DVDs with lots (tons?) of menus, Shawn, Steve, and Hal are absolutely correct.
    Take care,

  • Mini DisplayPort to HDMI transmits no audio on 2011 iMac with Lion 10.7.2

    Hello everyone. I'm new here.
    I have a 2011 iMac which was shipped with Lion and I updated to 10.7.2. I am trying to connect my iMac to my televison to play my movies, etc by using the HDMI connection. No VGA connection on this TV, which is what I used to use before upgrading computer and TV. I ordered a MDP to HDMI adapter from ebay which says it supports audio. The seller is reputable and I do not see any issues from their other customers.
    I have the MDP to HDMI adapter connected to an HDMI cable connected directly to my 46" Panasonic LCD. The video transfers perfectly, but audio continues to be played from computer's internal speakers. I've read through as many posts as I can find. I see many which tell you to select HDMI in System Preferences>Audio. There is no option for HDMI here. I only see "Internal Speakers" as the output option.
    I called AppleCare and even spoke with a Senior Advisor. They say I need to buy one of the two adapters they recommend in their support article. (I get the impression that they just wanted me off the phone.) Those are overpriced and I think this adapter should work, as I see other customers of this same product are satisfied.
    I've tried resetting PRAM and also SMC. I've taken a look at the audio settings on my televison, all to no avail. I don't understand why HDMI would not be shown in Audio under System Preferences. Any ideas? Thanks for your help!

    Same problem.
    All my equipment is directly from Apple, except two items bought December 2011, namely a 24" Sony Internet TV and a high end HDMI cable bought from Sony.
    My Macbook Pro 15" with its 10.7.2 Lion and Intel Core 2 Duo let's me plug in a Moshi DP HDMI adapter via the HDMI cable to the Sony Internet TV.
    By selecting the source on the Sony TV, I can get the display working. My Macbook refused to see the Sony TV until I switched to Mirror Display, but now I can switch between the two display modes fine with no problems.
    But the audio does not work.
    Really rather annoying, considering that there have been problems with this feature in several OS X generations now - after apparently working fine once upon a time.
    Dear Apples, kindly could you tell me when you will re-introduce audio support through DP HDMI connectors?

  • System Crash w/ m-Audio FW410 on iMac 10.5.4

    Ok, I'm posting this to see if anyone else has had issues with the m-Audio FW devices on 10.5.4. I have had repeated issues:
    m-audio driver version 1.8.4
    -no audio
    -device not recognized
    -Static
    -Kernel Panic
    -Device resets itself
    -and more
    I have read the threads and have kept close tabs on m-audio and their driver issues. I also see that there are posts about different iMac firewire chipsets.
    I also have a presonus Inspire and have had no issues occur. Below is the kernel panic I received today. can anyone help shed light on this. I am also working with m-audio tech Support to resolve and will be sending them my unit so they can test.
    I am very frustrated as my FW410 device used to be very stable under Tiger and then issues began to surface around 10.4.9 and continued with Leopard and got progressively worse. My device is pretty much useless since the audio keeps dropping out.
    I have gone through the myriad protocol of repairing permissions, install and uninstall the m-audio drivers, etc.. Hope someone here or at Apple can tell us what's going on:

    Yes, I'm aware that there have many driver related issues with m-audio. I actually purchased a Presonus Inspire as a backup. It works fine with no issues and it uses core audio, but I just don't like the preamps much. I must say m-audio Tech Support has been great, they are swapping my unit so I will be able to test the new device soon. If I continue to have issues though, I will have to move on to something else. What other interfaces use core audio and are not dependent on drivers?
    Thanks

  • Continuous audio during menu navigation

    Is there a way to have an audio track play continuously from one menu to the next? I'd like to have a song begin when the DVD is loaded and then continue playing as the user navigates through various menus. Once a video/chapter is selected, the music would stop and the audio would switch to the video... that sounds kind of odd, but I think you know what I mean.
    iMac G5   Mac OS X (10.4.4)  
    iMac G5   Mac OS X (10.4.4)  

    Unfortuataly thats impossible on dvds alltogether. the reason for that is that each menu is actully a separate video file which has its own audio track. DVDs cant have a single audio track run and then switch menues with that one track playing. just look at commercial dvds. None of them do that.

  • Noise through firewire audio device 27" iMac

    I am using ProTools 9 with the MBox Pro audio interface (8in - 8out).  I am experiencing an intolerable noise floor that I have narrowed down to coming from the firewire port itself off my new iMac i7 27' with 8G RAM with the 2G graphics. I have not even received my Apple Care package yet; that is how new we are talking!!
    Note that I tested against my MacBook Pro which is impressively quiet (all references to "quiet & noise" have to do with the firewire output), and exhibits none of these symptoms: The iMac powers up/boots and a few clicks can be heard while it locks in with the MBox. There is an almost immediate faint high-pitched whine that can be heard, very faint unless you were to turn the volume up, but something like the sound you would hear on a video taken from an airplane. Once ProTools opens, or any program that has some meat on the bones, the whine boosts up even louder.  This time it is an unacceptable "not good for business" noise. If you scroll the dock, or move the arrow across the dock, it sounds like white noise you would hear as if thumbing through stations on an AM radio.... and truthfully, because it is coming from my now questionable investment, way worse than an AM radio. This "dirt" coming from my firewire port is so strong, even after turning the Mbox off, this noise is bleeding right on through to my mixer anyway - even the AM radio noise when scrolling!
    If you let the computer sit at a modest volume, once the screen saver kicks in, every picture that comes up has it's own noise, sort of like you're hearing voltage spikes from a utility transformer... so I am wondering if this could be a bad graphics card since it seems closely related to what changes on the screen? Anyone who is having these sound issues, please share.  Last note: None of these conditions changed with relocation of my monitor speakers, new cords, screen resolution adjustment, or monitor brightness adjustments.

    " So make no mistake, this is an issue that should be taken into consideration by Apple to address and initiate corrections in the electronics/power supply/materials or perhaps the internal design.
    My follow-up post was an explanation of how I resolved the issue, but for the price, most who experience this will feel should have been resolved before their iMac was even assembled."
    James230,
    I have to say I do not agree with this comment.
    Apple can not be made accountable for electrical systems that are not up to today's standards and codes and causing noise on your power line.
    You state in your second post that the power in your area as no Earth ground and that the ground prong of your house's electrical system is grounded on conduit.
    In the end grounding to conduit is the same as grounding to earth since the water intake for your house IS in the ground so all pipes connected to it are acting as a ground to earth.
    The problem is that there is so much stuff connected to the water pipes, like a water heater, kitchen sink, washing machine, etc. that can create interferences, and make it a very noisy ground.
    "like the battery back-up, the AC connected to it is simply charging the battery but the actual power running the laptop is through the battery.."
    Not true.
    The UPS solution you used is the right thing to do, but not because of the battery.
    The battery in a UPS is NOT powering your equipment when you have normal electrical power on. It will only be used when the power goes out.
    Same thing goes for your laptop, the battery will only be used when it is not getting power from a wall outlet.
    The electricity is powering your power supply which is powering your laptop and charging your battery as needed.
    Remove the battery from your laptop and it will still run from power from a wall outlet.
    You are getting a cleaner ground because most decent UPS devices available today are equipped with power conditioning and noise filtering circuits that will eliminate most of the noise created by inadequate grounding.
    Also note that using a ground lift like you first suggested is not only dangerous for your equipment but could also be seen as "abnormal conditions" that could be used as a reason by any equipment maker to void the warranty on their equipment if a electrical problem was found to be the cause of damages.
    They could say: "Sorry, your equipment was not properly grounded, so we are not covering these repairs."

  • Help!!  No AUDIO output from iMac through FW to mixing board (zed r16)

    With my system stated below, I run an Allen-Heath ZED R16 board via FW. PROBLEM: I get NO Audio output to the R16 when I play iTunes or DVD/CDs in the iMac.
    I DO get audio feed when I playback projects from Logic.
    I have checked all System Prefs on the iMac (cahnged to the ZED); on Logic (changed to the ZED). I tried all different channels, routing, etc. NOTHING.
    Can someone help?

    Well, the Allen-Heath support site had the answer... quite surprised and pleased!!
    Have to reconfigure the iMac speakers in the Audio/Midi preferences. The details are found in this URL:

  • Does mini display port support audio on my Imac? Late 2009

    Hello,
    I would like to connect my Imac to my home entertainment system.  I have the late 2009 21.5" model.  If I get a mini display port to HDMI adapter will that run both audio and video for me or do I have to run seperate audio?
    Thanks!

    The good news is Yes.  You just barely made it, support for audio over MDP is:
    iMac (Late 2009) and later.
    Make sure to buy a MDP to HDMI adapter that supports audio.  It should say this explicitly like this one.

  • No audio when connecting iMac to LED TV

    I connected my iMac (using a mini display to DVI adapter) to my LED TV (using an HDMI to DVI Digital Video Cable), the picture appears but the only sound there is is that coming out of the iMac. Under system preferences their is only the internal speakers displayed in the output section. Please help!

    When you connected the mini-display port to mini-dvi adapter, you lost any audio possible. dvi standard doesn't support audio. If your iMac is a early 2009 or earlier, it doesn't support audio over the mini-displayport. The late 2009 and mid 2010 iMacs support audio over the mini-displayport per this article:

  • Combined audio & video from iMac mini DVI & headphone ports to HDMI to TV

    I presently have my iMac connected to my Sony Bravia tv so that the video goes from the mini DVI port through a converter to HDMI to a 25 foot cable, a HDMI coupler and another 25 foot cable to the TV. The video quality is good since I use 24 AWG cables. The audio goes from the headphone port through a 50 foot 3.5 mm cable to a converter to RCA stereo cables to the tv. The audio quality is not very good with this setup and I would like to send the audio over the HDMI cable with the video so that I would have only a single cable over the 50 foot run and could use a HDMI wall plate for a neater installation. I am wondering whether anyone has tried this somewhat expensive solution to my kind of problem, and whether it worked. Atlona DVI + Digital Audio to HDMI Converter. Model: AT-DVID-HDMI

    Not sure if it would work. The audio input is described as +audio (SPDIF) input+ which is not analog or the Toslink optical digital. SPDIF is a digital format, so you would need another converter. And since the video input is full DVI, you'd need a different adapter for the iMac's video output.
    Considering the complexity, additional adapters, rather long travel length, and $199 price for the Atlona device, depending on what you want to show on the HDTV, you may want to consider an Apple TV. The older 40GB version is $149 at the Apple +Special Deals+ page. You can then stream your content wirelessly, and not have to worry about any cabling. But obviously, an Apple TV does not stream everything that that iMac can play, so it would only work if what you want to show is stuff you can play in iTunes. Plus you may want to see what Apple introduces at the 1/27 special event.
    The iMac's audio output port doubles as an optical digital port, with a Toslink adapter, so if the Sony Bravia has optical digital input, you may be able to run a Toslink cable. I believe 50 feet is too long, so you would need some type repeater at the midway point.

  • Audio in my iMac is not working

    Any help?
    thanks in advance.

    yes, its probably the best solution, but I'll lose 6 ou 7h to restore all files to a new computer, go to the shop... at least onde day spent in a week with lots of work to do.
