Use of optical out on new macmini dual core

I bought a new ~Belkin optical cable. It fits perfectly in my macmini and my bose 321 system. This 321 system has an optical entry. But ....
the description by the mac how to get the mac to use the optical out is not told. It is told to select optical out in the configuration screen under sound. I don't have this option! Ithought the updat of the minimac would have solved the problem, but it didn't. Please help me! I want to use this optical cable, so that I can use the bose system in combination with the minimac!
Kind regards David Rietveld

With the exception, as noted of the DVD player, it's System Preferences>Sound>Output. Make sure you used the mini-toslink/optical adapter and that the cable is securely snapped into an INPUT port on your bose system. Everything will be (as noted) auto-detected, and you should see the option:
Digital Out Built - In Output
Select it. If you have multiple adapters for sound (ex a usb audio adapter), then you might want to select the digital output for use only w/ dvd player. Choose where you want your system sound and alerts sent in the other tabs of Sound.
On your bose unit you may have both analog and digital inputs for the same source. I'm not questioning your competence, more my knowledge the equipment you are utilizing. Make sure you select OPTICAL as the input for that source.
For example,
You have buttons for Video 1, Video 2, and DVD. On the back you have a coax digital, a couple of toslink/optical digital connectors and a bunch of RCAs. If you hook up ALL the wires from each device then press Video 1; it MAY just use the analog connections...and since you're ONLY sending digital you won't hear a thing.
If you have 'auto-detect' for analog or digital it probably prioritizes digital over analog and will merely work IF SELECTED. Some systems may do the reverse.
Good Luck,

MacMini 2011 - how to ground it?

My MacMini 2011 has a two-wire-only power cable, and when you touch it, it "feels electrically ungrounded", especially if you are touching other items connected to it or nearby.
How should I ground the MacMini?

Hi William,
Are you in the US, using a 110V system?
I have not disassembled a Mini but it is not uncommon for switching power supplies to capacitively couple one of the AC power legs to case ground. This may explain the tingly sensation, especially if you are also touching another piece of equipment that is grounded. I am not aware of any "factory approved" grounding method.
You must rule out all other equipment as its cause. Disconnect everything connected to the Mini as I suggested earlier. If the problem disappears look elsewhere for its cause.
I do not know why Minis use a grounded connection while iMacs do not, but capacitively coupling the case reduces the Mini's ability to contribute to electromagnetic interference. I presume this is to comply with the many certification standards to which the equipment is subjected.
Some time ago I responded to this thread in which the OP wanted to find a wired, non-optical mouse for EMF sensitive user. Klaus1 suggested a link to a site (lessemf.com) that is not working now. Perhaps that site, or something similar, could be perused to find an elegant way of grounding the case. Drilling and tapping a hole for the purpose of bonding its case is not something I would do to a Mini.
You must first be absolutely certain you do not have another problem that is causing this. As I suggested earlier, you must be 100% certain that all your house wiring is correct, and that the Mini as well as all the equipment connected to it is working properly. An improperly wired system can result in circulating currents in what you think is "ground". This can cause problems that will drive you up a wall.
If something is amiss, grounding the Mini's case will only hide a symptom and could cause it or other equipment to fail in dramatic fashion. I had a ground fault once, the manifestation of improper wiring in a rapidly expanding office. It resulted in $15,000 worth of damage. Leaving the Mini's case "floating" with respect to ground is safer from that perspective.

Which external sound card with optical out is compatible for macbook

hello guys!i got a macbook model 2011 and i want to connect with my speakers which is logitech z5500 with an optical cable!Of course i have read a lot of answers in various forums that told me about the optical out of mac which is the headphones out too!but this doesnt give me real surround 5.1 and i want something more specific such as an external sound card to give me the real sound!i prefered Creative Xfi pro but i have also read that iOSX doesnt recognize the soundcard or have various problems!
please help me !!!!

No Creative sound cards are fully compatible with Vista at this time. Nobody really knows if or when there will be fully working, stable drivers from Creative that work with Vista. If you really need sound, the only fully working cards are from C-media I believe. My on-board C-media sound chip works perfectly with Vista.

Optical out not working

When I plug an optical cable (with the right 3,5mm optical plug) into the headphone jack of my iMac, it is not recognized as an optica digital output. In the system preferences, the sound output changes from "internal speakers" to "headphones".
On my MacMini however, the sound output will change from "internal speaker" to "optical digital out"
I wondered if my iMac really has an optical digital out, and the system profiler is positive on this. Could the optical out be faulty?
Deatils on the iMac: 2.4 GHz Core 2 Duo with OSX 10.7.2, 4GB RAM, 24" mid-2007

Sound Out:
1
Headphone:
1
Details:
Single shared "headphone/optical digital audio output".
Long shot, but...
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there.

MacMini (2011) problem with Thunderbolt display if 2nd monitor is connected via HDMI/DVI adapter

Hi,
iam running a MacMini (2011) 2.3GHz i5 with Mac OS X 10.7.4 16 GB 1333 MHz DDR3 256 GB Samsung SSD.
If i connect a Thunderbolt display only - all is fine.
But if i connect a 2nd monitor ( Samsung S23A700) via HDMI / DVI adapter (original Apple) the major screen (Thunderbolt Display) sometimes
is going black and immidiately back to normal. It looks like that it happens very often if i scroll down with the Apple Magic Mouse.
Any ideas?
Thanks in advance
Thomas

I have exactly the same problem. MacMini Server i7 (mid 2011) Macmini5.3.16Gb ram.
Mini and Thunderbolt no blink-outs.
Mini and Thunderbolt and Dell 23" connected to HDMI-DVI connector, the Thunderbolt display blinks out when system is under stress as in the Develop module of Lightroom 4.
I thought it was a problem with my Thunderbolt display, and since its on a VESA mount, I didn't really want to haul in in to the Apple Store. I decided to be sure it was the dosplay...
I borrowed a MacbookPro i7 and ran it from a clone of my Mini. No problems aster hours of use. (But with only ONE monitor.) That suggested that there was no problem with the Thunderbolt Display.
I decided to run the Mini with only one display. Again no problems. I plugged in the Second monitor to the HDMI port and within 2 minutes I had my first "Blink-Out".
I ran the rest of the day without the second monitor with no problems.
I conclude the mini will not work reliably with two monitors if one is a Thunderbolt.
I was using two Dell Monitors before I got the Thunderbolt Diskplay (for 3 months) without incident.

When I plug my headphones into the headphone/optical out jack programs hang

I have an iMac 20 inch LCD. On the back their is a jack with a picture of headphones, but it is also labeled as "optical out". I plug my headphones in and they work. Great. That is not my problem today.
My problem is that whenever I plug the headphones in or unplug them, iTunes (and other apps using audio) hangs and when I try to adjust the volume with the keyboard buttons nothing happens for 15 seconds or more and then the volume changes, not that anything is able to play. If I wait for a minute or so then all my applications start working fine again and I am able to hear my music and adjust the volume.
What in the world is going on?
1.8 Ghz G5 1.25GB RAM Mac OS X (10.3.9)

Thank you. That is good information.
Does this mean that there is nothing I can do about the delay? When I think of a delay, I think of maybe 10 seconds. I am having to wait for a minute or more for my audio to switch. While I wait, I have no audio and any audio program hangs. Is there a setting I can change? It seems rather ridiculous that I have to wait so long just to switch from internal speakers to headphones.
It is like this on other Mac machines? Or it is just my iMac? I hate to compare Mac to Windows, but on Windows or Linux computers the switch is instantaneous.

How to switch off the red light (optical out) on my Audigy 2

I am not using the optical out most of the time, is there a way to switch off the red light coming out of optical out?red light is causing heat leading to cracks on the surface of the card.Please help soon. thx

Are you sure? AFAIK, LED's don't produce any significant amounts of heat. And, no, I don't think the light can be switched off.

Creative inspire t6300 5.1 surround on mac pro 1.1, optical out to 5.1 audio gear (digital sound decoder).

Hi there,
Been searching and trying a lot but no luck so far. I have a surroundset Creative Inspire t6300
to be able to add some more fun to movies and a few games on my mac.
I own an upgraded Mac Pro 1.1 under Snow leopard, 2.33 gHz, dual processor, 8 core, 8 gb memory.
Even though it`s a piece for the museum, it works very well for designwork I do for work. No real need
to update for me, so....
As I understand, the optical out is standard 5.1. (By the way, the only other ports are the basic sound ports out
and in on the Mac). So after some research I found and got the 5.1 audio gear decoder. I connected this with
an opticle cable and used the 3,5 jackets from the surroundset to connect to (from left to right) cen/sw, (yellow
jacket) fl/fr (green jacket), sl/sr (black jacket) on the decoder. All perfectly understandable and it seemed to work well.
But when I tested with some of the testfile you find when googling on that, I think there is something wrong,
the typical surround effect is not there, it rather sounds more like stereo or even 5 mono`s.
I`ve tried Soundflower and JackPilot, but couldn`t get it right. With Soundflower I was able to choose 5.1 setting
(was not possible before) but testing it didn`t work.
There is an extensive test of the decoder on the net by someone who really is deep into the technics of it all but
no luck there either.
Back to basics: is it right that the optical out is truely 5.1 on the mac? With several tests the unit SFE does not react.
But when I play some music with iTunes, it works (loud and clearly :-)). Maybe I need a visit to the audiologist ;-) ?
Anyone?

Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?

Hooking up the digital optical out to my stereo reciever

I just got a new Core 2 Duo Mac Mini and I want to hook the digital optical out to my stereo. However, I noticed the connector does not seem to be a standard stereo optical cable. What do I need to do to connect this to my stereo reciever which supports digital optical in?

Actually some toslink cables that yoiu buy, come with them. I remember buying a 6' Philips that included the adapters.
Oddly enough, I think I found it at Wal*Mart (maybe target).

No optical-out sound on MSI KT4-Ultra!!

Hi, I have recently set up a system based on the MSI KT4-Ultra board. I'm using an Athlon XP 1700+, a Radeon 9000 video card, and I've installed Windows 98.
Although all the drivers and audio applications which MSI provided installed fine, and 2-channel audio from the on-board sound chip works great both for music and for the 3-4 games I've installed so far, I can't seem to get the optical SPDIF port to work! I bought a cable and connected the computer to my Sony MD-player and attempted to copy my CDs onto MD. I go into the MSI control panel and check the box to enable SPDIF-out, removing the speaker cable from the analog line-out just for good measure. When I plug the optical cable into my MD it recognises digital input and prepares for recording. I press record on the MD and play on the computer's CD-player app, but the MD LED shows "no signal". I'm pretty sure both the MD recorder and cable are OK since I've used them to copy CDs from a Kenwood portable CD-player quite recently, so it must be the MB that's giving me problems. Indeed, when I've stopped playback in the CD-player app and went back into the audio control panel, I found that the SPDIF box had been unchecked of its own accord. I've tried this several times, and I've unplugged the S-bracket and reinstalled it all over again just to make sure it was plugged in properly, and I still get the same problem. All audio works fine except optical out! Haven't got a coaxial cable or recorder so I can't check if the coaxial port is equally buggered or if it's just the optical, but I'm getting really annoyed here: this was the one feature I liked best about this board and the only one which isn't working! Any ideas, anyone?

dude, i think i can get u ur signal, but currently i can only get silent recordings, u may have better luck.
on the minidisc, there should be a switch or button that will toggle synchronised recording on and off, turning it off should get u a signal, but it wont be in sync wiv the cd, ie u cant trust it to form track gaps.
hope that helps, done flame me if it dont, if i manage to get substance to my recording, i will send u the info just in case.
take it easy

Optical out sends constant noise to speakers

Hi,
Is it normal that when I connect the optical out to the surround sound system the speakers produce a constant hissing noise. If I connect any other device with optical out to the surround system instead of the AppleTV, the speakers don't produce this annoying feedback noise. Is this a problem with my specific AppleTV or is this a design malfunction in all AppleTV devices.
The noise always has a constant volume.
I have tried connecting it to a different surround sound system, and the AppleTV
still produces the same noise. It's likely that most people won't be bothered by
this, but I have sensitive ears and I did expect high quality output from this
rather expensive device (given the limitations apple has enforced upon it, even though the hardware is capable of so much more).
Thnx.
(To bad I couldn't get online support from Apple for the AppleTV, seems
they only have e-mail service for iTunes store????)

This is a public update of Lion available since last night.
No a developer thing.
Click in your "Apple" menu (top left) and then "Software Update"
The usual procedure.
I have left my machine on all night long and the sound is still good and the "SoundStay" app is still runnig fine.

Connecting 5.1 desktop speakers directly to optical out on iMAC - how?

I have Logitech X-540 speakers
http://www.logitech.com/index.cfm/speakersaudio/home_pcspeakers/devices/234&cl=us,en
I can only find external sound cards that hook through USB. Is there a way to connect the 3 colored cables (orange, green, black) from the Logitech speakers to some conversion cable or cable converter to connect to optical out on the back of the iMAC? I have read the forums and can't find much aside from connecting your iMAC to a home theater setup. Thanks!

Is it even possible to do optical out to 3 - 1/8" (3.5mm) stereo minijacks

Nope. The iMac's optical out is an AC-3 encoded digital feed, but your
speakers require six decoded analog signals. You need a 5.1 decoder --
something like FireWave, or a DolbyDigital receiver, or a speaker system
with a built-in decoder.

Audio Probelms with some DVDS/BLU-RAY discs when using optical out to Audigy 2

I have my PS3 connected to my Audigy 2 ZS soundcard via optical?cable to play 5. sound on my PC sound system (Klipsch Promedia Ultra 5.). I have finally successfully played discrete 5. sound with some DVDs. I have changed my optical out setting to bitstream in the DVD/BD menu (XMB) and selected optical with everything checked in (XMB). So far, The Matrix, The Matrix Reloaded and Minority Report have worked in proper 5. (not stereo matrixing). Both Dolby Digital and DTS tracks (I know it works because it sounds twice as good as Dolby?Digital) ?work in Minority Report. The problem is... Jurassic Park (DTS) and my Blu-ray MIssion Impossible 3 have no audio (probably more too). The STRANGE part is if I fastfoward both films by .5x (so that audio plays in FF) I can hear audio. When FF by .5x the display signal on the top of the screen changes from DTS or DOLBY DIGITAL: Multi Channel to DTS or DOLBY DIGITAL: 5..
What is with that?Also I still do not get audio in any games, Resistance (Blu-ray)?or any game demo but I do get the audio from the game display screen (XMB). Please if anyone has?any?useful advise or information it would be greatly appreciated.
?Thank you!
