Sound through projector

I am using Keynote for a presentation and have a video on one of the slides, but when I play it through the projector the audio doesn't work. The audio plug looks like it is too long for my headphone hole. The plug that we are using has three prongs in a circle on one end and a hole that looks like it should fit in my headphone area on the other end. Any suggestions to get the sound working?

According to my experience.... you need audio cable from your mac (audio-out) to projector.

Connecting MacBook to Sony Bravia KDL-40XBR9 - No sound through TV

I recently bought a Sony Bravia KDL-40XBR9. I have it hooked up to my MacBook using an HDMI to DVI connection. But, I'm not getting sound through the TV. So, I bought a 3.5mm to RCA (one red, one white connection) cable. I've plugged the red and white connections into all of the red/white ports on the back of the tv but I'm still not getting sound out of the tv.
Can someone please help me with this setup?
Thanks!!

Does your Bravia also have red and white input jacks on the side of the TV (my Bravia does, on the left). On my Bravia, those are the only audio inputs that are active for all inputs, and they are what I use when I am playing my MB through HDMI (which, as you found, only transmits video).

Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

Sound through hdmi to my tv works but not when watching video online like 4OD

the sound through hdmi to my tv works with music and videos I have downloaded, but not when watching video online like 4OD and youtube.
How can I get it to work?

Ok so I happened to figure it out while on the phone to apple support. Even though the guy was very nice, I think I knew more than him! He was explaining very basic resolution principles I played about. I had the second option in displays resolution. All I did was unplug the HDMI cable, click on 'best for display' then plugged the HDMI in and my resolution on the normal monitor changed to the normal blue, then went black momentarily and then changed to a strange resolution but another window appeared that said SONY BRAVIA HDMI at the top! Hey presto! Don't know why it didn't do it yesterday - I probably left the HDMI cable in or something! Oh well. Problem solved!

5g nano no longer plays sound through (any) dock!?

I recently got a brand new dock, and it is, without a doubt compatible, with the 5G nano.
It played out loud through the dock with no problems for a few weeks, but it suddenly stopped transferring the sound through to the dock the other day, and instead, now, it just plays through the external speaker on the actual iPod. I tried it through my friend's dock too, and the same thing happened.
This is all to do with the internal connection, because when it first happened, I found that if i wiggled it around in the dock and held it at a certain angle, it played. However, that only lasted a few minutes and then it just stopped playing through the dock altogether.
It's strange because it connects to the computer fine through the exact same slot, and I can transfer music fine.
Saying that...on the day ot happened, the song I had just transferred from the comp onto the iPod magically disappeared from the device. That was weird. So I had to put it on again. And it definately went on the first time; I saw it in the playlist.
Anyway, all I can think of is that I have 'dislodged' something inside the iPod when connecting it into to the dock, or i've 'pushed something out of place internally' maybe...because I have not been using the dock adaptor (the iPod doesn't fit inside the adaptor because it has a plastic case over it). So maybe i've pushed it too far down into the dock slot or something?
Can anyone tell me if they've had this problem too?
Or if so, how much would this kind of thing cost to get repaired? Or have I mucked it up so bad I may as well give up now and get a new one (unless I never want to use a dock again)?

I just purchased my 30gb video iPod, and am running into almost the exact same situation. The only difference is that I don't have to reset it. It just won't play a movie at all. It starts the little "timer" thing that clicks around, but then goes back out of the movie. I know the movie is a good download, because I can watch it from start to finish within iTunes.
Anyone got any ideas? I really don't want to stay on hold for 1-2 hours waiting on a person to talk to with tech support!

Ipod touch no longer charges with USB nor does it output sound through the connector

2 problems after the latest iOS update:
(1) my 3rd generation iPod Touch no longer changes when connected to the computer through the USB connection. It says that the device is not supported for connection through USB. My computer is running Snow Leopard and all software is up to date.
(2) it also does not output sound through my clock radio nor through the built-in ipod connection in my MINI.
This all worked great until the latest iOS update. Something broke in the latest update.
anyone else seeing this issue?

You can try the standard fixes:
- Reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod.
If still problem then the iOS broke full compatibility. you have to then wait for either Apple to fix the problem in an iOS update or for Honda to fix it via a firmware update/
Have you contacted Honda?

No sound through headphones/microphone ALC892

I've been trying for days to fix this issue, and am lost. I've got a new desktop and cannot get sound to come out my headphones, or take input from my microphone. I believe my sound card driver is installed correctly, and that it is a pulseaudio problem. I've gone through the troubleshooter on Arch's alsa, and pulseaudio wiki pages. I do get sound through my monitor speakers when I use HDMI, but would prefer headphones. I have tried Debian, Linux Mint, Manjaro, and crunchbang and none of them have had working audio for me.
where I see a problem is in pavucontrol, all my profiles, and input/output devices say (unplugged). So in output devices, and next to Headphones it says (unplugged) when it is plugged in, same with my mic. i see the visualizer playing to the music under headphones though.
everything is unmuted in alsamixer.
I've tried both the front panel mic/headphone port, and the back panel.
thanks in advance.
EDIT: i did get sound to play through my roommates USB headset, they have there own sound card. So sound does work, but I cannot always use these and still want to get sound through my headphones/mic.

Perhaps you have previous configuration files on your system (~/.asoundrc or similar)? You might want to look at you mapping of signal paths/jacks with hdajackretask found in alsa-tools (Frontpanel might be inactive on your particular hardware setup). Double check if correct module model is loaded for your card (line 36).
If you kill pulseaudio, does aplay produce sound?
To unload jack detection module this should work:
pacmd unload-module module-switch-on-port-available
Some people have issues with pulseaudio since upgrade to 5.0, so checkout changelog for configuration changes, here in forum there are several topics on this matter.

Windows 7 on my iMac won't play sounds through headphones

On Windows 7, I can't make sounds play through my headphones plugged into the audio jack; the internal speakers always do it instead. The headphones don't appear in the "Playback devices" column, even though RealTek recognises that something's been plugged in/unplugged to it.
Also, the latest version of Boot Camp software drivers I burned to a DVD after upgrading to Lion (v.4.0) refuses to start; it keeps saying that 'Boot Camp x64 is unsupported on this computer model"; I was able to install the v.3.0 drivers by using "Troubleshoot compatability" within the Drivers/Apple/BootCampx64 before, but now it insists I use setup.exe- which refuses to install, even in compatability mode!
It's incredibly aggravating, since I always use my good headphones for gaming so I don't disturb my wife! Help!

So the Bootcamp 4.0 drivers won't work with my 2008 iMac? I'm running 3.3 then, and the problem persists.
I've just tried uninstalling the RealTek drivers; Windows seems to auto-install a "High Definition Audio Device" that DOES play sounds through the headphones... albeit incredibly quietly. Barely perceptible at full volume. I've tried to install the Cirrus drivers from the 4.0 Bootcamp disk; they claim to install correctly (in less than a second, which makes me skeptical), but they still don't appear.
It seems I can have Realtek and no headphones, or no Realtek and minimal sound...

My Iphone 4s says connected to TV and will not let me watch any videos on Safari, and only plays sound through the device. I have not messed with the settings, and have not connected it to anything bluetooth either. It's update is IOS 6.1.3

I have an Iphone 4S and It won't let me watch videos on my safari, which I do everyday. It says that I am connectef to a tv, yet I have not connected it to a tv during the entire time i've owned this product. I have not connected it to anything bluetooth either. It plays the sound through the device, but it will not play the video at all. the update is IOS 6.1.3

Try disabling the computer's antivirus and firewall.
- Next try the manual install method of:
iDevice Troubleshooting 101 :: iPhone, iPad, iPod touch
Place the iPod in recovery mode after the firmware download is complete and then restore using the instructions in the article. Sometimes recovery mode timeouts and returns to disabled before the firmware download is complete.
- Then try on another computer

[SOLVED] No sound through usb soundcard in Google Chromium

Hi there,
Before switching to Arch I had used my external usb soundcard in Ubuntu and Kubuntu which worked almost flawlessly except for no sound through Google Chromium in Kubuntu. I thought this may have been isolated when switching KDE on Arch but I'm stilling having the same problem. All audio works through the external soundcard except for Chromium.
Does anyone know how I can change sound preferences in Chromium or other way to solve this problem?
Thanks,

Not sure exactly what I did but I fiddled with the default soundcard configuration and now it works.

Can't get sound through my big speakers

Hello all,
I just hooked up my new Apple TV and all works fine BUT can't get any sound through my big floor speakers, only through the tinny TV speaker (Samsung 46" LED).
The big speakers are powered by an older Onkyo FM AM receiver with no optical digital audio port. I currently enjoy sound from these speakers when watching my Comcast cable stations or my DVD player, choosing respectfully between video 1 and video 2 ports on the receiver.
Question: Do I need a new receiver with an optical digital audio port, to be then connected to the Apple TV via this cable ?
My Comcast cable box has such a port. What would happen if I connected an optical digital audio cable from the Comcast box to my Apple TV ? Would the sound find its way into my big speakers while watching Netflix ? That's all I want.......
I don't have this darn cable now to try this.
Thanks guys.

Hmmm....would that limitation be noticeable by average listeners ? I don't even know what 5.1 audio is.
5.1 is surround audio with L/R front, Center (mostly for speech), and L/R rear channels. You'd need 3 extra speakers for the additional channels.
The .1 refers to a subwoofer but if your main speakers produce good low frequency as it is it may not be needed as low frequencies tend to deliver less spatial information than mid/highs. If you wanted one it'd be an extra speaker.
You would notice the difference by virtue of having sounds spread around you rather than simple L/R on movies that support it (Dolby Digital 5.1). As your amp doesn't support this currently, you're not ging to miss anything going the stereo audio route for now.
I've had a 5.1 system (without the .1) for donkey's years, and yes it's fun/novel, but leads to more clutter in the room with leads extra speakers etc. In fact I've relocated my rear speakers some time ago and am just sticking with stereo for now.
Certainly worth looking into, but 5.1 is old hat anyway and more modern surround formats will utilise even more speakers for surround effects but AppleTV currently does not support these.
I'm running a pair of old tower Polk Audio speakers of my amp that vibrate the windows pretty good.
No reason you couldn't use these in a 5.1 or 5.0 system as main L/R speakers but you'd need new center and rear L/R speakers, cabling and amp +/- subwoofer.
Onkyo would still be a good bet for a quality reasonably priced amp though you'd probably find a myriad of options, possibly cheaper than your original Onkyo.

My ipod video wont play sound through the headphone jack or the bottom connector

Hello everyone. I have an iPod Video 60GB (supports video output through the headphone jack). Which I believe was the last one before the iPod "classic".
Anyways awhile back it stopped outputting sound through the headphone jack, I assumed I had damaged the jack itself as commonly happens but it stopped outputting sound through the dock connector to my ipod speaker dock and my cars ipod connector. The clicker wont make any noise either.
When I tried to search for an answer to this problem years ago I couldnt find anything and knowing it would be out of warrenty I put it aside and forgot about it. Having searched again recently it seems as if this could be the audio processor or some component on the board coming loose? Has anyone outlined this problem with pictures and steps to repair it?
I *may* take it in and pay the $30 but I would much prefer to fix it myself. Thank you for any help with this.

Update: The model # is MA147LL. Not sure why my edit didnt take effect.

No sound through the HDMI connector using Qosmio G30-201 & Vista

I am getting no sound through the HDMI connector using VISta.
I have XP and Vista on my laptop.
When i boot into Xp I can get the sound to come through the television but when I boot into vista I have no sound coming through.
I have just reloaded both partions with Xp and vista so it is a fresh install on both and it is still doing the same thing.
Please help.
Cheers
Steve

There is a nice an useful Toshiba FAQ about this issue!

No sound through HDMI alternative solution

If you are not able to get sound through your TV through HDMI and have tried all the System Preferences/Audio MIDI steps detailed on here in other threads but nothing works, try just shutting down all running apps.
I had to Force Quit Spotify, Viber, Skype - when I shut down iTunes, the sound from Firefox started coming through the TV. I have since been able to reopen Spotify and play it through the TV too.
I'm not sure why these apps would interfere with the HDMI sound transmission, perhaps more technically inclined people can answer this but it turned out to be a straightforward solution that I didn't find on here (although maybe I just didn't look hard enough!).

Is it an occasional problem or is it that you have never had the hdmi audio output working with windows 7 Ultimate? If it has never worked, is hdmi even listed under playback devices when you right-click the speaker icon in the notification area and click playback devices?

No sound through HDMI in Radeon 6870

Hello People from Arch Community
I have a small problem getting sound out of the HDMI of my video card.
When I do
lspci | grep AMD
I get:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Barts XT [ATI Radeon HD 6800 Series]
01:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Barts HDMI Audio [Radeon HD 6800 Series]
So the kernel finds the device. But when I do
aplay -l
I get:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC887 Analog [ALC887 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC887 Digital [ALC887 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
I noticed that the HDMI out was listed as Audio Generic, when it should be identified as HDA ATI HDMI. Whenever I choose the HDMI output through alsamixer I only get a s/pdif and I cannot modify anything. I remember that some months before when I installed Arch for the first time sound through the HDMI was working and the audio device was correctly identified. Could it be a new module or kernel path that broke the audio?
I tried using the radeon.sound=1 flag but I still could not get sound out of the HDMI. Even worst, when I use the radeon.sound=1 parameter, my screen display a 5 pixel width purple line at the left border of the screen and the rest of the screen gets squeezed. It is not too bad but still makes text look blurry.
Could someone help me please?
Extra info: it is not hardware related, sound works fine in windows
I am not a total beginner, I know my way in the CLI but still I lack a lot of knowledge.
Another tip, around the same time, my framebuffer decoration and splash(fbcondecor, fbsplah) stopped working, I don't know if it is related.

You may find this article >Here< to be of interest. I don't know much about Radeon audio but for your 6870 that may seem to be of relevance.
Are you using the open-source driver or the proprietary with an older X.org? With the above article, the open-source audio seems to be slated for kernel 3.5.
