Can't get audio via HDMI

I have a brand new MacBook Pro (Dec. 2012) purchased with a Moshi HDMI Adapter
The cable and TV I am using work fine with another HDMI source.
I have done everything the instructions say. The video works fine and the TV shows up in System Preferences / Audio / Output but nothing changes when I select it. The sound continues to go to the built-in speakers

They do. I use an inexpensive Monoprice adapter - here - and get audio and video from my 15" late 2011 MBP. You should be able to do the same with yours. It may be just a faulty adapter - you can get the one from Monoprice for less than $7 and try it out.

I have installed an ASUS EAH5450 silent graphics card to my Pavilion m7210 desktop but get no audio via HDMI output.I have 2 high Definition Audio Controllers in Device Manager, One has an exclamation mark with message
" This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.
You need to restart your computer before the changes you made to this device will take effect."

The other HD Audio device is likely to be the Realtek ALC880 8-channel High Definition onboard sound. This is a bit of a decision point. If you plan on always using the AMD High definition Audio as your default ouput through an HD TV with HDMI out, then you can disable the Realtek HD audio device. Once that is done then restart the PC. Go to the Control panel and select sound, now sellect the AMD HDMI out and right-click and select it as the default. There should now be a green checkmark next to it. Now you can select Configure to test it.
Kind regards,

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.

Need help to transfer 5.1 audio via hdmi

Hi, guys!
This is my first post, I would like to apologize for my bad english.
Today I received my new Mini DP to HDMI adapter and, after a little configuration, I was able to make it work properly with my mac.
But, after all my work, I noticed that the audio transfered was only stereo, not 5.1 as my home theater can handle.
So I searched some forums for a bit and noticed that I could try to change my configurations in "audio and midi configurations" (this is a portuguese translation, I'm not sure how is the program's name in english). Once there, I saw a lot of choices for audio via hdmi, like stereo, 5.1, 6.1 etc, but only the first was availabe, all mutichannels were disabled.
Is there any way to make these choices available?
Can this be a limitation of my Mini DP to HDMI adapter?
In the item description, it says that it does transfers "uncompressed audio such as LPCM" and
"compressed audio such as DTS Digital, Dolby Digital(including DTS-HD and Dolby True HD)".
Thanks in advance!
Cheers from Brazil

As far as I know there is no way to carry more than stereo over HDMI.
I know very little about this subject and have no experience with it myself, but I've been aware for some time of this adapter:
http://kanexlive.com/products/iAdapt51.html
I take the description to mean that 5.1-channel digital audio can be carried by HDMI, and if the mini-Displayport doesn't output an audio signal that rich, the Kanex adapter should be a useful alternative. I've posted the link in reply to many queries in the past, but I don't recall whether or not anyone has posted back to say they've tried the adapter and tell how well it worked for them.

On my iPhone 4 I can play music through the speaker or headphones, but I can not get audio in phone mode, I can't hear anything nor can anyone hear me! Help. Please.

On my iPhone 4 I can play music through the speaker or headphones, but I can not get audio in phone mode! I can hear anything through the ear piece or via a headphone. Nor can people hear me when I call. I must be doing something wrong, but what?

Hello Angela,
Thank you for the details of the issue you are experiencing with sound on your iPhone. I recommend the following steps for an issue like this:
Verify that the volume is set to a level you would normally be able to hear.
Ensure that there is nothing plugged in to the headset jack or the dock connector.
If the iPhone is in a protective case, make sure that the speaker port isn't blocked by the case.
Make sure that the speaker and dock port aren't clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush. Carefully and gently brush away any debris.
If an audio issue occurs when using a specific application, try testing other applications to see if the issue persists.
If the iPhone is paired with a Bluetooth headset or car kit:
Try turning off Bluetooth.
If you experience difficulties with the Bluetooth feature, followthese troubleshooting steps.
Restart the iPhone.
If restarting doesn't fix the issue, ensure that your iPhone is updated to the latest version of iOS.
If the issue is not resolved after restoring the iPhone software, please contact Apple Support.

How can you get audio for books on the kindle

how can you get audio for books on the kindle

The audio inputs on Macs are line level inputs and not mic inputs. You need a mic with a built in preamp (battery powered) or more conveniently a USB mic or bluetooth headset.

Can't get audio to work on my Panasonic Plasma smart TV when I connect a Toslink optical mini to Toslink optical digital to my mid 2009 MacBook pro?

My MAc book pro 5.5 is mid 2009, Processor speed 2.26 GHZ MacOS X VERSION 10.68 Leopard. My Tv is a Panasonic Plasma smart TV TC-P50ST60. I ordered from Amazon a Toslink optical mini to Toslink optical digital cable meant for Macbook pro 2009 forward. I changed the settings on both TV and Mac but I still can't get audio to work on TV. I believe my Mac can't see the audio output from the TV. Any advice with step by step instructions on how to fix it? could it be they sent me defective cables? Thank You for your help.

When I spoke with Apple I made sure I told them that my Macbook Pro was Mid 2009 and he ensured me again that those to cords will work. I realize that with the newer models it does put through both sound and audio but because of my model I don't think it does obviously because I have played with both Sound on my computer and Sound on the TV and nothing works. Sometime Apple can be good but man some people lol he even told me he verified my computer model on the computer and that's what came up.
So new question would be what kind of cable would I be looking for to get audio? Anyone before I call back to Apple and see what they say hahah

Can I get audio through iPhone when using apple tv?

Can I get audio through iPhone when using apple tv?

What do you mean exactly? Are you wanting to output the audio to your iPhone while say watching a video on your Apple TV? If so, I'm afraid it's not possible. However, you should post this in the Apple TV forums for a better confirmation on then. There are some prettty knowledgable people who hang out there.

IMac 27" (Late 2009): getting audio to HDMI receiver via mini DisplayPort

I just got my first iMac 27" and I'm in the process of integrating it into my home theater system. Here is my setup:
iMac 27" connected to HDMI receiver (Yamaha RX-V1800) via mini DosplayPort, using miniDP-to-HDMI adapter + HDMI cable
Optoma HD20 video projector connected to HDMI receiver (HDMI out) via HDMI cable
I have Windows 7 installed via Bootcamp 3.2, so that I can take advantage of Windows Media Center. With the above setup, I am not getting audio or video signal to my receiver and video projector when I'm using Windows 7. However, when I am in OS X environment, I can get both video and audio signal to my receiver and video projector, and either mirror or extend my video diplay. When I do plug in my iMac straight into my video projector or LCD monitor with built-in speakers while in Windows 7, I get both audio and video output. So why doesn't it work -- and only under Windows 7 -- when the signal goes through the receiver?
My immediate thought was that it must be something about the receiver, but since the setup creates no problem under OS X I don't think it is. Could it perhaps be the Windows driver for mini DisplayPort, because it looks like iMac is not 'recognizing' my receiver and therefore not establishing connection? Is there a driver of fix available that takes care of this problem?
Thanks!

I've tried a few times and it hasn't worked so far...
23" Cinema Display (ADC) connected to Apple's ADC to DVI adapter/power box then connected to Apple's DVI to mini Display Port adapter.
Trying to output extended desktop from iMac to 23" Cinema Display.
No signal or anything on the 2nd monitor so far.
USB port on Cinema Display works with the setup.
Checked system updates and all up to date as of 01-10-2010.
OS X 10.6.2 build 10C2234

Monitor audio via HDMI or Optical?

My Saffire interface just died and I am looking for audio solutions other than firewire or even usb because I am now using a Retina MacBook which has HDMI. I am running 5 M-Audio speakers powered from a subwoofer.
Is anyone outputting audio through this - I want to monitor 5.1 surround? Instead of buying a new usb interface I could get a tv style receiver for HDMI and output to my speakers that way. Could be good enough to mix and monitor.
USB audio interfaces with 6 outputs are fairly expensive so this would save some bucks.

I monitor surround sound via my MiniDisplay Port to HDMI. So for your retina, you can use the Thuderbolt to HDMI connection. Look here for more details https://discussions.apple.com/thread/3639822
I use this to monitor and mix surround sound within AVID Media Composer.

No audio via HDMI (dv9700t CTO)

HP Pavilion dv9700t CTO Entertainment Notebook PC / Windows Vista 64bit
I have set the default audio device to the "Realtek Digital Output" device. I get no sound.
I upgraded the audio drivers from the HP support site. Still no sound via HDMI. (microphone quality was reduced to the point of being worthless)
I upgraded the drivers again with drivers from the Realtek website. Still no sound via HDMI. (I regained microphone functionality)
The reciever that I am trying to connect to indicates that there is no audio signal being sent to it from that source (my laptop). I have even tried connecting directly to the tv. That did not work either.
Its almost as if there was no connection between the audio hardware and the HDMI port.

I also have this problem my laptop is a Pavillion dv6000, when i first got my Sharp LCD every thing worked fine, i had both video & sound now my sound doesn't work. I cant point to exactly when my sound stopped working exactly, but i do let the computer do the regular updates with the HP update service. reading else where http://www.fixya.com/support/t1284552-hdmi_audio_not_appear_installed_hp it appears the problem may have occurred after one of the updates.
