No sound from optical output when using hdmi/dvi cable

I am trying to connect my apple tv2 to my B&O Beovision 7. I have used an HDMI to DVI cable which is working fine for the picture; but obviously DVI does not carry sound. I have therefore connected an optical cable to the digital optical output on the apple TV and put this through a converter to digital coax, which then goes in to the TV. I know the optical cable / converter set up works fine as I have tested it on my sky box and it works fine. But I get no sound from the apple TV - any ideas?

I hav exactly the same problem... Did you resolve this??

No sound from the TV when using HDMI cable, No sound from the TV when using HDMI cable

I recently purchased HDMI cable and adaptor, so that I can play downloads from my Macbook Air on my TV. There is only sound from the Macbook, not the TV - Do I need as separate cable for sound?

I've got the same issue: when I connect my Macbook Air (2011) to TV via HDMI cable there's no sound through the TV system, only from the Macbook Air. I used to use my older Macbook Pro with the same HDMI adapter and it worked just fine, but not with the Macbook Air it doesn't.
My software is up to date. I tried to select the TV as an output option in sound preferences, but it doesn't yield any results.
Rebooding multiple times doesn't help either.
Any suggestions on how to tackle this problem?
Thanks in advance.

No sound from Vision box when using HDMI

I have my Vision box coupled to my Yamaha AV amp by HDMI cable. When switching the Yamaha inputs to the Vision box I get no sound . If I switch the box off and back on again then all is OK.
Does anyone have any ideas. I have a Humax freesat bos also connected that way but that works OK as above when switched to it

I have a similar problem, but not with my Vision box.
I have four HDMI inputs going into my AV receiver: Vision; DVD; Apple TV and; Freesat HD. I can switch between them all quite happily with the exception of the Freesat. If I switch to Freesat then I will always get a blue screen until I turn the Freesat off and on.
It's a little annoying but you learn to live with it.

How can I get audio to play from my TV when using hdmi cable? Video looks great, just no sound.

How can I get audio to play from my TV when using hdmi cable? Video looks great, just no sound.
I've tried plugging the hdmi into the TV directly and the receiver.
I get video every time. HBO to Go , Xfinity, ABC, Youtube, etc...
just no audio. Any suggestions?
I've tried starting the apps then plugging in the hdmi cable.
I never tried this before I upgraded to IOS 5.

Claudiamil-
I had not tried it with mine since upgrading to iOS 5, so I just did. I'm using a small Vizio HDTV. I did not try YouTube, but did try several videos and musical numbers. In all cases there was sound, including stereo when the source had it.
I assume you are getting sound from the iPad when the adapter is not connected, so the volume is not turned down. Dah*veed's suggestion to reset may be what you need.

Help with sound to LCD TV when using HDMI

I would love any assistance with a problem I am having. I have a new mac mini with a 40" Proscan LCD. I am using a mini-DVI to HDMI adapter and am getting great video - 1080. My issue is that via Keynote I need to get sound to the LCD TV. It is coming through the mini speaker - what do I need to do to get the sound over to the TV? Any assistance would be appreciated!

Welcome to the Apple Discussions!
The user guide which came with your TV should cover the issue in the different connections available for your unit.
DVI is video only. HDMI is audio and video. If you are using an adapter to connect DVI to HDMI there is no audio because of this. So to connect a Mac mini with a DVI to HDMI adapter you will also need an audio cable to run the audio from the mini's audio outport to an audio inport on the TV. This is why I refer you to the user guide for your unit, because it should point out the correct port to use on the TV, as well as point out if you have options for using analog or digital audio. The mini's audio ports can do both.

I get no sound from my guitar when using iRig with my iPod 5th gen (iOS 7)

I've just bought my iRig and it doesn't work with my iPod 5. I get no sound out of my guitar.
Headphones are working and when iRig is connected I can hear the samples and every other sound coming out of the iPod, but I get nothing from my guitar.
I tried shutting the iPod down, turning Mono on/off, but it still doesn't work with any of my apps (Amplitube, Garage Band and AmpKit).
Then I tried it with my brother's iPod 4 and it worked perfectly, which makes me think that there's something wrong with my iPod settings (I got the iOS 7)....
Does anyone know something I could try?
Thanks!

Contact the developer/go to their support site . Maybe it is not compatible with the 5G iPod. Also, it may not be compatible with iOS 7. Did it work on the 5G before iOS 7?
Restore from backup. See:

Can alerts sound from main speaker when using earbuds?

I have headphones connected all day although they're not always in my ear. (Either connected & Bluetooth) If I receive a call, the ringtone sounds through the external speaker AND headphones. (This is good). Alert tones (email, calendar) sound ONLY through the headphones; so, if they are not in my ear, I may not hear it. (This is bad).
I can't find a setting to change this. This would be easy for Apple to allow and makes sense to me. Any time I don't want sounds, I would toggle the mute switch - which is easer than changing a setting anyway.
Is there an App Store app that will allow this?

Nope.Try to REMOVE the headphones when you are not using them.This,Sir,is the only solution.

No sound from TV when using HDMI from HP Envy Ultrabook4 despite downloading drivers

Problem: When using an HDMI cord from my HP Envy Touchsmart Ultrabook 4 (4-1105dx)to connect to my TV to view movies, the video appears on my TV screen, but there is NO sound from the TV. Instead the sound comes from my lap top.
Troubleshooting: I have looked under Sounds in the Control Panel, but the only choice listed is Speakers & Headphones IDT High Definition (which is the default) and does not allow sound from the TV when using the HDMI. I have also tried to download Driver and Audio Graphics, but wasn't sure which one & the ones which were downloaded have not solved the problem.
Can you assist me? Which is the correct Audio/Graphic Driver to download? Or is there another possible reason why I cannot hear sound from my TV when using the HDMI to connect to my lap top?

Hi,
Please try this first to enable Speakers in Playback devices as follows:
1. Right click speaker icon (bottom right hand corner)
2. Select Playback devices
3. Right click HDMI sound
4. Enable it
5. Click Apply/Ok

When using HDMI to HDMI cable the Master Sound Control is locked.

master sound control is locked when using HDMI to HDMI using an HDTV for the display.
Although itunes sound control works. Why is the Master Control locked?

Hello,
I am new to OS X and i have tried to adjust the sound when plugged to the secondary monitor through HDMI which of course didn't work.
I have been using windows and a linux for years now, and everything works seamless.
I believe that this could be easily solved by Apple as long as their are willing to do it. Having a virtual device for sound control is not that difficult.
All the bests
There are two ways to 'solve' this.
Alter the volume before sending the digital signal down the HDMI connection, this means the signal is no longer exactly as it was originally. Apple's current (apparent) view is that this should be done at the end i.e. playback device not at the originating (Mac) end so as to minimise the number of devices making changes to the signal. Basically 'volume' is the amplitude of a an analogue wave form. (Where else do you think the term 'amp' comes from.)
Not to alter the volume of the signal at the Mac end but instead to send a signal down the HDMI cable to tell the end i.e. playback device to alter the volume, this uses a standard called CEC (Consumer Electronics Control), unfortunately at the moment no Macs support this standard - it has to be supported at a hardware level so a simple Apple software upgrade to implement this is not possible. I have previously logged an official enhancement request for this with Apple - the more people who do this the more likely it is to be added, since now all Macs include HDMI it might happen at some point.
As an addendum to option 2 above, see http://www.pulse-eight.com/store/products/104-usb-hdmi-cec-adapter.aspx this would however require software support in whatever application is being used. XBMC for Mac does support it.

When I call someone using FaceTime from my mac, they can see me but no hear me. Is there something I need to do to make this happen? I also have an iPad 2 and FaceTime works great on it if I call somebody. Why no sound from my mac FaceTime using a mac pro

When I call someone using FaceTime from my mac, they can see me but not hear me. Is there something I need to do to make this happen? I also have an iPad 2 and FaceTime works great on it if I call somebody. Why no sound from my mac FaceTime using a mac pro and isight camera, mike combo.
If I use google it works. If I use Ichat, it works. If I use skype it works.

This sounds like something similar to https://discussions.apple.com/thread/3388112?start=105&tstart=0.
Try turning down the speak volume (System Preferences->Sound->Output->Output Volume) or the microphone gain (System Preferences->Sound->Input->Input Volume). Do this on both sides of the call.

HT201335 What causes the TV screen to freeze but sound continue on TV when using Air Play from I Phone?

What causes TV screen to freeze but sound continue on TV when using Air Play from I Phone 4?

First try rebooting ATV and router. Beyond that, it's probably something within the network, typically interference.
To get a report of the network go to istumbler (Mac) or netstumbler (PC). Look for signal strength and noise.
If on wifi try ethernet.

I am using iMac OS 10.7.2 with Garageband'11 6.0.4. I can't record sound from mixer Behringer X1622USB using USB out. when I connect the mixer to iMac via USB appears USB Audio CODEC on Sound and preferences but no sound from mixer to iMac. Need help.

Eric,
Thanks for your reply. Realtek audio works only in playback. There is a stereo mix in the mixer but the recording controls are not operable with no sliders in the mixer for any recording option. Slider controls appear to be grayed out. Can't figure out how to enable them. Downloaded newest drivers to no avail.
The M Audio control panel has no apparent option for recording stereo mix. Adobe ignores the sound from the DVD or CD and shows flatline.
I'm trying to record the sound from the DVD not rip the track.
When I go to Audio Driver Setup and select Audition 3.0 windows sound, there is no input device installed.
I'm thinking of going back to a decent internal Soundblaster card like I have on my 8 year old machine I am replacing.

[iPad Mini no Retina, iOS 7.0.4] Sound in only one side of earphone (no mic), but sound come from both sides when using FaceTime

Recently, I found with iPad Mini w/o Retina, iOS 7.0.4, the sound comes only from left side of my earphone when listening music, watching YouTube videos, even playing system sound. But the sound come from both sides when using FaceTime.
Earphone is not broken. Plug completely into the audio jack. This problem only shows up recently, worked fine weeks ago.
Anyone has the same problem? Or has some solution on this issue?

Hello Ramanan,
Report Builder : connect JDBC Query in Report Builder is to through Connection Dialog in JDBC Query Editor. User can use a Sign on parameter (can use, default : P_JDBCPDS or can create new) to connect to JDBC Data Source. Connection once made will be mentioned and will be reused through out Reports Builder.
JDBC PDS allows user to connect one or more same or different kind of databases.
While running report through runtime or Server, user can pass the sign on parameter(connection string) value, like any other user parameter.
Syntax for connection string : <username>/<password>@databaseURL . The syntax of database part of connection string depend on the type of JDBC Driver used to connect to Data Source while designing the JDBC Query. databaseURL refer to the location of the database and its format depend on the JDBCPDS river selected in design time while creating the JDBC Query.
rwrun eg :
rwrun report=jdbc_odbc.rdf destype=file desname=output.html desformat=html P_JDBCPDS=scott/tiger@database
Server eg :
