No sound from rear audio out port?

Hey guys.
I am trying to troubleshoot a sound issue with a Vista Home Basic machine.
I can't really give you all the MOBO specs etc because I am not currently in front of the machine. I can however confirm that it is using a Realtek chipset and is configured using the Realtek Sound Manager software.
I am really just wanting to use basic sound (i.e. just speaker, not 5., 7. etc).
I am trying to make use of an old stereo system by using a 3.5mm aux jack to dual RCA (white and red) plugs.
I can get sound when I plug the aux jack into the front earphones port but I cannot get sound when I try and use the analogue audio out (lime green) port at the rear of the machine. Vista states that it is working correctly and has a tick next to the speakers but no sound is produced by the speakers.
The MOBO has the following available audio connectors:
Analogue = Mic in (Pink) Audio in (light blue) Audio out (lime green)
Centre Speaker (Orange) Rear Surround (Black) Mid Surround (Grey)
Digital = x SPDIF
You may ask at this point, why not just use the front headphones jack? Well, the problem is that it seems to be very sensiti've in that Vista keeps reporting that the jack is cycling between a connected and disconnected state.
I also cannot use the SPDIF, as the old stereo only supports aux left and right RCA.
Also, when I try and get one of the rear ports to work, I have made sure that nothing is connected to the sound ports at the front as I know that this can cause problems.
When I plug in the 3.5mm jack into the green port, the Realtek sound manager kicks in and says that "a jack as been connected". I then confirm that I have infact connected the jack to the rear audio out port. I then follow the steps in the wizard but am not able to get sound.
I made sure that I used the most basic settings (i.e. speakers and not 5. etc).
I even tried the grey, black and orange ports (even though I know they are used for surround sound setups) and still no luck.
One interesting setting I did notice was that in Winamp, I had to select the "allow mono speaker" setting to have it play sound through the front headphones port.
However, when I was configuring the rear green port in the Realtex Sound Manager software, there was no mono option. There was only stereo, 5., 7. and some quad....... thing.
Any ideas guys on how to get the rear green port working?
I am wondering if it has something to with a connector on the MOBO. But as I said, Vista and Realtek manager seem to report that all is well.
My thanks in advance.

Why doesn't the Belkin Thunderbolt Express Dock relay sound from it's audio out port?

Posted to Belkin Support community to no avail

Why can't my Belkin Thunderbolt Express Dock operate my desktop speakers?

Bought a Belkin Thunderbolt Express Dock at the Apple Store to use with my new MacBook Pro.
When I connected it to my
-20" Mac Cinema display,
-Various USB connected hubs and devices,
-Various Firewire hubs and devices
-My ethernet network from my Cable Modem
Then made the last connection from the Dock to the Thunderbolt port on the MacBook Pro...
All was fine.
But when I made that one last connection - to my desktop speakers via the audio-out port on the dock (earphones icon) nothing happened. The dock did not pick up the audio from the laptop playng an iTunes song or send it to the desktop speakers. When I unplugged the audio cable from the Dock and plugged it in to the MacBook Pro directly, the desktop speakers kicked right in again.
Does Thunderbolt pick up audio-out from a MacBook Pro and carry it to the Dock for connection to my desktop speakers?
Of for some reason, can that signal not be carried by Thunderbolt?
Will I have to get used to the onerous task of unplugging 2 cables from my MacBook Pro when I want to more it to another location in stead of just 1 cable?
But stay with me. Here's the thing.
When this happened I called Belkin Customer Support to ask if they could help me. After taking me through their steps, they agreed that the unit must be defective and agreed to ship me a replacement Thunderbolt Express Dock.
The replacement arrived over the weekend and when I shut down my system and then plugged everything from Dock I purchased into the replacement Thunderbird Express Dock - - - - - the same thing happened!
No signal to the speakers from the dock. Perfect signal when the plug moved from the Dock to the computer itself.
Hence my question:
Does Thunderbolt pick up audio-out from a MacBook Pro and carry it to the Dock for connection to my desktop speakers?
Can it accomplish that function?
Am I really that unlucky to have received 2 defective new Belkin Thunderbolt Express Docks in a row?
Or is it simply a matter of the Dock not handling audio throughput in the manner I am expecting.
Then again, if this is the case, why did the Belkin techies not know this when I called them in the first place.
Yes, I'm going on and on here. But I really don't have time for this.
What's going on here?

OK. No reason to be playing games here. Just surprised that this issue hasn't been brought up here on the community boards as well. Here's the simple solution

After reaching a Level III technician in Belkin customer support today and having spent approximately 4-5 person hours on this issue, we figured out that the Sound/Output preferences in the Apple System Preferences should not be set to "Internal Speakers" but rather set to "USB PnP Sound Device".
Worked like a charm. Simple, elegant solution to a real problem, one likely to be encountered by 90% of the people who buy a Belkin Thunderbid Express Dock off the shelves of any Apple Store to use with a current generation Apple laptop or desktop computer.
But the Level III Belkin technician admmtted that this critical little piece of simple, straightforward information should have been readily available to their Level 1 techies who began helping me 5 person hours ago. Would even have saved Balkin loads of customer service support time.
And so the saga ends
Belkin owes me for helping them learn this precious lesson.

Digital audio out port

I am having a problem, quite opposite to what most of what I've read about Mac audio port issues online, concerning my audio-out port. I'm running an Intel Imac, 7,1, running OS 10.5.8. The specs do specify the audio port on this mac is dual; analog and digital output. Everything I've read to date relates to the red optical light being stuck on coming out of the audio port. My issue is that I CANNOT, and I emphasize that, get the red light to come on and thus use my optical cable (it's working on other equipment) and connect it to my AV receiver. I have never in the past even thought about using an optical cable so it never was an issue. In fact I never knew the port was dual. The external speaker and headphones work fine and the audio panel in the preference pane reflects that; either says 'internal speakers' or 'headphones' automatically when engaging/disengaging audio phone jack. When I put in my toslink (optical) cable, the panel goes to 'headphones' instead of 'optical out' or 'digital out'. There is never a provision to click on digital out on either the sound panel or the midi setup panel. I've tried everything I can click on at both panels. Audio Output in midi setup says 'master stream' (always greyed out) and Source- either 'headphones' or 'internal speakers'. The default and system output drop downs never give me a 'digital' or 'optical' option. Everything works fine except that I cannot get the red light to shine and cannot get digital out at all. Any ideas? Maybe something in terminal or in openfirmware screen? Thanks.

have you tried other speakers or headphones and what version bootcamp drivers are you using?

Audio out port is intermittent

I couldn't decide what category to choose, because my MacBook isn't "black and white". It is just white.
The audio out port (marked with headphone symbol) is intermittent with headphones or speakers. I can't say what causes it. Unplugging / plugging in again sometimes restores the sound, but more often it doesn't help. If the sound is anywhere but at the lowest level, I hear the typical momentary bzzzz sound when the plug is inserted, but no sound from the QuickTime file itself. If I unplug the speakers / headphones, the sound always works through the built-in speaker. The only login item is iTunesHelper. The only application open is QuickTime Player. Software Update shows "Your software is up to date". Disk Utility shows drive appears to be OK.
Is there a firmware update or audio port fix that doesn't appear in Software Update?

I have since found that this is a rather well-documented issue with MacBooks. Various solutions include sticking a toothpick in the jack and deleting prefs. None of this works with mine, as it didn't for many others, so maybe we have to wait for some firmware update that can fix the combo-digital-analog jack thing.

HT2844 iMac 27"(late 2009), Audio in/Optical digital audio out port, stopped recognizing my new Bose speaker system, previously working...

Hello,
My iMac 27"(late 2009), Audio in/Optical digital audio out port, stopped recognizing my new Bose speaker system, previously working through that port. I tested the speaker system through my iPhone, and it works fine. I hooked it up to the Headphone out/Optical digital audio in port, and it works through that port also. I did a computer restart, I also checked all wiring and did a system repair on the computer. I also restarted the computer in mode where I could use the system utility, and the computer still did not correct the matter, and it reported everything as being "ok". I wented into "sound", through system preferences, and the computer does not recognize anything I plug into the Audio in/Optical digital audio out port. When I plug the speaker sysytem into the headphone out/optical digital audio out port, it does recognize the Bose speaker system as being "headphones".
Reading through a lot of forums, I hear everything from compatibility, to the port being stuck, and on and on. Since the port was working before, and just quit working one day, I wonder if there is a capacitor or fuse or some type of similar thing is blown, and causing the port to be unfunctionable. Maybe the port went bad, but before this time, I had never used it, and the computer does not move around, and I never plug in and pull wiring out unless needing to, and that being rare.
Here is a link to Costco, where I bought the system, and the exact system I have, if this is any help: http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku= A4092931&ST=pla&dgc=ST&cid=262075&lid=4742361&acd=1230980794501410
By the way, I am running OS X Mountain Lion (10.8.5). I upgraded to Mavericks about a month ago, and expeirienced a number of issues, and had to take my iMac into Apple. Talking with the tech, I decided to wait for a while more before I upgraded to Mavericks. I try and keep the computer maintained.
If any of you have any ideas regadrding wear and tear, and fix I can do, etc., besides having to take my computer into Apple? Thank you, and potentially all of you, for your time and effort in helping me with this issue. Thank you kindly.
davE

Okay, davE, first, you have posted in the "Mac Pro" forum (not Macbook Pro), so we can't be super helpful
but we help you. First, hold down the Option key while clicking on the speaker icon at the top of your screen. This should show you all the inputs and outputs you have. you could check in "About this Mac" then "More info" to see whatever's recognized. Then, maybe, fire up Audio MIDI. your speaker system should show up there. something might have gotten set incorrectly. You can test it there. I guess you are using the good ol' analog cable for connection, and it works on your iPhone, so the cable isn't bad. You could try this. it 's an adapter which might solve your problem
http://www.amazon.com/gp/product/B004HBWYQ6/ref=oh_details_o00_s00_i00
depending on which model of Bose speaker you have, you might try doing a product reset
turn off speakers...unplug power cord from outlet...wait 1 minute..plug cord into outlet..turn on speakers..
\\turning off automatic standby||
press and hold top of control pod for 6 seconds until you hear 2 tones that go from high to low
other than that ,I don't know

Expand mini to two audio out ports?

I am thinking about purchasing a Mac mini, but I noticed it only has one audio out port. I am using both audio outs on my Dual 1GB now - the audio out on the back panel and the headphone port on the mirror front. I use one for speakers and one to my stereo.
Is there a way to have two audio outs on a mini? I am not sure a Y-connector will work (impedance issues?), and an A/B switch will only give me output on one line at a time.
Any ideas? Some kind of 3rd-party device?

One option would be to use a Bluetooth headset, a second option would be to get a USB audio interface or USB speakers, and a third option would be to run speakers from your stereo system (many modern AV receivers support more than one set of speakers).
What are you trying to output? It sounds like two different thins at the same time?

Optical digital audio out port

Here is the situation:
The only problem I have with my Mac Pro is that the Audio line-out port does not work reliably in Boot Camp. The audio output cuts out easily and then I have to "jiggle" the speaker cable to get the sound back. And I have determined that it is the audio line-out port that is at fault, not the speakers, nor the cable.
So I want to try to work around this by utilizing the optical digital audio out port.
But I don't understand how it works.
Does this port connect directly to appropriate digital speakers?
If so can someone recommend a decent set of digital speakers that will connect directly.
Or does the optical digital audio port connect to an amplifier or receiver and them to speakers?
Thanks

1/8th inch Audio out port

I have a digital audio coax input on my stero reciever. When I connect my macbook 1/8th inch audio out port to the coax input on my reciever, my stereo says that it cannot detect any digital signal. Is that because my macbook output is sending an analog and not a digital signal? Or what other reason would there be no signal? My macbook port works fine with headphones.

Yes, there are "mini-Toslink" to Toslink adapters and cables that have a mini plug at one end and a standard size plug at the other end. Apple has one cable that comes with a mini adapter:
http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore?productLearnMore=TL9 55LL/A
The mini adapters used to be available as separate items (in case you already had a cable) from Amazon.com and Radio Shack, but I've been unable to find them recently.

EDIT: An adapter has re-appeared at Amazon.com here.

Why no sound from rear speakers (Xfi X

Vista 32bit, CMSS enabled, why no sound from rear speakers with music? XP no problem at all, only in Vista. Using latest drivers (v2.5.0004).
I realize I'm hoping against hope to get a useful answer at the Creative forums, but I do believe in miracles and the odd one happening once or twice in a lifetime, lol.

Well, I think I have an answer, from Catherina-CL's Audio in Windows Vista post. 2.The Vista audio architecture changes the way per-stream audio processing works, which required us to write new software to support this
Issues that may be encountered:
CMSS no longer works on audio streams from the OS.
Status:
Features based on Windows XP architecture must be rewritten to conform to the new Vista architecture, and we have a team of software engineers, project managers and testers dedicated to this task in order to provide our customers the same seamless audio experience under Windows Vista that they enjoyed under Windows XP. However, I found a somewhat crappy solution, at least with my old Altec Lansing 4 speaker/ subwoofer system. Unplug the surround cable from your subwoofer (unplugging it from the card itself has no effect). That at least will make all the speakers work, even if it's not true surround. Good for listening to music loud.

Audio out port doesn't work well

Hi, I have a Macbook Pro 13-inch, Early 2011. Since I bought it I always use my Mac whit headphones, but since a month it only works well the left headphone. I think that the problem it was my headphones but no, because I used it on my phone and workes well. So i come to the conclusion that the audio out port doesn't work well. What you think? And what you recommend to me to fix this problem?

Probably still under warranty, but not for long. Take it to the Apple Store or AASP to have it checked ASAP.

Soft sound from rear speakers while playing mov

Hi,?Gaming and music is done via all speakers (i'm using analogue connection) just fine, but when i play a movie (using powerdvd 6?deluxe) i get faint sounds from the rear speakers. I had contact with creative's help desk in my country and we ran thru all system settings (e.g. thnx console). Everything was configured correctly., tho still a weak sound from rear speakers. They could not help me further ?I'm using a x-fi fatality soundcard with a logitech z-5400 speakerset.
When running a movie it shows a logo near the system tray : dolby digital. I am hoping one of u has a solution to this problem. Greetz,?Nask

In most of the cases, movies with mutichannel soundtrack do not use constantly every speakers. I think your case is normal and that's only your DVD's mix (as many DVD) that concentrates more on the front. try some of the sample there: http://www.digital-digest.com/dvd/do...s/trailers.phpIf the first one sound at the same level for each speakers then it's alright.

No sound from iPhone 5 headphone port stopped working

No sound from iPhone 5 headphone port stopped working

Try a restart.
If no effect, then try a reset.
If no effect, then try a restore from backup.
If no effect, then try a restore as new.
If no effect, likely a hardware issue, and you should schedule an appointment at a local Apple store.

Interference/background noise from audio-out port

I've connected my audio-out using a Monster cable from the headphone jack into the audio ports of a flat-screen TV. There's some kind of interference or background static noise. It almost seems to correspond to activity on the computer: if I'm loading a web page or the hard drive spins, the frequency of the static increases. It's rather annoying since I've connected it to watch Netflix and DVDs on the TV.
Any thoughts on what causes it or if there's anything I can do to stop it?
Thanks!

This sounds very much like the problem people have when using separate displays and audio amplifiers. I would try the Radio Shack audio isolator transformer. If that works, this setup also has the ground loop problem discussed in other threads.

After reading some threads I come away with some ideas and thoughts. I haven't tried everything, and there are a lot of unhappy customers out there. Creative, take note. In today's competiti've markets, you must look at yourself from the customer's viewpoint. Right or wrong, you must stri've to delight your customers, and resolve issues.
