Audio and hdmi

My monitor(projector) has no speakers and I have no receiver that supports the optical audio output. Is there a way to preserve the hd video going to my monitor while separating the audio so I can use a sound system to amplify the sound? I'm nervous the answer is no or it will be expensive.
Thanks for any suggestions!

Very few consumer display devices will convert digital audio to analogue, so even if your projector has an audio output it will be very unlikely to work. You will need to use the optical output from the Apple TV and connect it to a DAC, which can then be connected to your sound system.

W540 + Dock station (40A20170EU), Audio and HDMI problems - SOLVED

Hello,
I have recently bought your dock station (40A20170EU) and as soon as I started using it the problems began:
- Audio jack on the dock is not working and is emitting static.
- As soon as I connect a display via HDMI port (on the dock station) my laptop display starts flickering (the display was tested on the PC and works).
I have updated the dock firmware to 2.21.000, nothing changed.
PS. The second monitor running from the docking stations display port is working fine.
I need your help!
Thank you!

SOLVED.
1) Removed all display drivers.
2) In BIOS I changed the display setting from standard to advanced.
3) Reinstalled all the display drivers.
4) Reconnect the HDMI monitor and now it’s working.
5) WINNING J
Thanks anyway.

Audio to hdmi after W 8.1 update

After fixing audio in windows on my laptop with your solution (thanks so much!)....I still had no audio to hdmi cable and tv display. Playback devices showed only Speakers/HP in listing. I tried adding a second display device to no avail. At one point I had Speakers/HP highlighted and showing as default, when i inadvertently right clicked on it and a menu popped up.
I t had an option to show all disabled devices , so i clicked it and Ouila! My samsung tv showed on the list as disabled. I enabled it and it set as default. Tested fine! Now my question is: Can laptop audio operate independently and at the same time as the second display audio? Just hoping my mom and I can each have our cake and eat it too.
Thanks again for your help.

Need a mini display port and audio to HDMI adapter for mid 2009 13" macbookpro

Can some body recomend an adapter cable that plugs into the audio (mid 2009 MacBookPro 13") and mini display port and outputs to HDMI with audio and video all together for a TV? I would rather not run a separate audio cable in addition to the HDMI cable.

http://www.kanexlive.com/iadapt51 - 5.1-channel surround sound from sources that provide such a signal
http://www.kanexlive.com/iadapt20 - 2-channel stereo sound

Does the mini displayport able to transfer audio and video to an external monitor (example: a tv) using a 2011 13" MacBook Pro with an hdmi cable?

I was wondering this, because I want to hook up my 2011 MacBook Pro to a external monitor (TV) using an hdmi cable. This would be heplful before I buy a mini displayport to hdmi adapter, and then maybe find out that the mini displayport might not transfer audio, only video.

Yes, min Displayport supports audio and video for the 2011 MBP 13" via HDMI.

Not sure that I have selected the correct forum. Hope my questions are clearly stated.
Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter. TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices). It does not show Mail or Safari menus. System preferences' display "gathered" the Samsung and chose its resolution. I did not find a way to select the Samsung as my display.
In addition to having old hardware, we have Verizon FIOS providing internet and TV access. Is there any way to make this work for us? We would like to stream video (Netflix) and view shows from the Web. Do we need Apple TV to do this? Or is it not possible with our old iMac? My husband thinks that our Airport could be a factor.
Thank you

Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
There are, actually, many alternatives to choose from than just from a Mac.
You need to have or invest in a WiFi capable router for all of these examples.
Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
If you have a older Mac, like I have noticed many users do, then you have other options.
If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time, you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

HP Pavilion dv9218tx Notebook PC and HDMI audio problem with Sony TV and Windows 7

Sound does not come through with the HDMI connection and, on investigation, there is no HDMI audio driver/option.
Noting that there seemed to be an issue with windows 7 and HDMI audio which is addressed by updating the BIOS and the connexant sound driver I have done so to no effect.
The Sony TV is recognised as a standard monitor in the devices for graphics but not for audio
Suggestions as to why HDMI does not appear - including as a disabled service - and what to do t get is available?

Need full resolution HDMI audio and 2 CH optical simultaneously

Am working on an install for a customer who has a Mac Mini. He is running XBMC for all his movies. I need to run HDMI to his surround processor with full resolution audio while running the optical out in 2 channel pcm for his whole house audio. Is this possible?

As standard sound would go to one or the other output, it is possible to configure things to send sound to both at the same time, but I would strongly expect this would require both to be configured the same i.e. stereo, rather than one being stereo and the other 5.1.
To configure the Mac to send to both you need to use the Audio MIDI Setup tool in the Utilities folder.
See https://support.apple.com/kb/PH5178?locale=en_US
and How to combine multiple audio interfaces by creating an aggregate device - Apple Support
It maybe that the easiest or more practical option would be to use an AV Receiver set to output via both its stereo and HDMI ports. The Mac would then just send via HDMI to the AV Receiver which would if needed handle the conversion and splitting of the signal.

Audio and DVI to HDMI on my G5?

I have my G5 dual 1.8 GHz wired to my Vizio 32" HDTV as the primary display with a DVI to HDMI adapter and then an HDMI cable going to my TV. I get good 720p video out of it with the original Radeon 9600 graphics card but of course no sound as DVI doesn't transmit audio. Does anyone know of any good adapters would take the existing DVI and digital audio out and convert that to a single HDMI????
Something just like this except instead of a mini DisplayPort, DVI.

Hi-
Something like this, perhaps?

Trouble running DVI video and HDMI audio out of 6950

Twin frozr iii 6950 2gb (X2 crossfire)
Asus VG236 Monitor
Windows 7
MSI P67A-G43 Motherboard
Yamaha RX-V371 Receiver
I have two Twin Frozr iii 2gb 6950 cards and am attempting to use the HDMI on the video card solely for 5.1 audio out to my receiver while using video through the DVI jack of the same card directly to my monitor without success.
-Audio functions if I run the HDMI from the card into my receiver, then out to my Asus VG236 monitor.
-Audio functions when I run from the card to my receiver then out to my plasma tv.
-Audio functions if I have the DVI run directly to the Asus VG236 monitor and HDMI to the receiver then plasma tv (only in dual display and the tv must be on for audio to function this way. If I turn the tv off even though the receiver is still on the audio stops working and windows sound lists the 'AMD HDMI Output' as not plugged in).
-Audio even fuctions when I run DVI to the monitor and HDMI to the receiver, then out to the HDMI port on the same monitor but the monitor will only run at 60hz this way even when DVI is selected on the monitor, as though it defaults to the HDMI when dvi and hdmi are both plugged into the monitor.
And if i run the hdmi to the receiver "HDMI IN" port without using the "HDMI OUT" port from the receiver to anything, like my tv or monitor, the sound doesn't work and in windows sound the "AMD HDMI Output" is listed as "not plugged in" .
I purchased this monitor for the true 120hz capabilities, the HDMI on this monitor doesn't support 120hz, the maximum is 60hz. DVI is required to run at 120hz. I don't see any option in windows sound settings or CCC to resolve this.
I have also tried disabling onboard audio in BIOS with no effect.
For now i'm running the audio out my MOBO jack through an optical cable to the receiver but optical only supports 2.1 sound.
Any suggestions you can offer would be appreciated, thank you

bump,
Anybody?

Audio through RCA and HDMI not in sync

Hi,
Is this a common problem?
Recently got a tv with hdmi so the appletv is now connected with hdmi to the tv. But it is also still connected to my stereo though the rca connection (for music or movies with soundtracks that I really want to enjoy).
Problem with both music and movies is that the audio is not in sync between hdmi and rca. Hdmi is a bit delayed.
Now for music this is not that much of and issue as I usually have the tv off and use the iphone remote to select music on the appletv which plays then through the sereo. But for movies it is, I have to turn off the tv volume completely. It was much better to have the sound of the tv also on for dialogue, gave a more natural impression if it did not only come from the stereo. But with the delay it is just not good anymore.
Any ideas, known problem? Fixable?
Thanks,
S.

Most modern TV's have an input lag during which various processing is applied to the video signal, and the TV audio will be delayed accordingly - the longer this delay the more you're likely to notice a discrepancy between RCA/optical and HDMI.
This is not the AppleTV's problem.
While you might want both audio outputs playing together it invariably causes problems.
Only if your amp has some kind of delay function on the input could you compensate by slowing teh audio from the amp.

Multiple Audio out: usb dac audio out and hdmi out

Good afternoon everyone, I have a 2010 mac mini with the following audio set up.
- A usb dac (xtreamer) connected to my stereo amplifier
- an Hdmi cable to the tv to get video and audio diretcly to the tv
Is it possibile by any chance to get simoultanesly audio output both from usb audio out and hdmi audio out???
In "midi preference panel" I tried to create a "virtual" sound card but i am not able to get sound simoultanesly. or via hdmi, or via usb.
this is quite disappointing because if I want to listen to music with the amplifier and then watching a simple video with mac mini and tv only I need to go back to the audio preferences and set up manually each time.
Is it possible to solve this issue???
Thanks a lot and gretings from Italy

I can select ATV audio out (Airplay setting) to either my Airport Express or my computer so it must be transmitting via airplay. Using a combination of Airserver, Airfoil and Airfoil Speakers I managed to get the ATV audio content on both my PC and my Airport Express at the same time but it cuts out the ATV audio.
My aim is to have a movie on ATV transmitting the Audio to ATV AND my stereo (which is hooked up to the Airport Express).
Cheers

Can I port Apple TV audio to RCA and retain audio from HDMI?

Odd situation: My Audio receiver only allows RCA Analog for the outdoor speakers and will allow, but will allow digital for indoor speakers. I want to get my mom an iPad so she can easily either play audio while outdoors (using the Red and White Analog) and at the same time have the Apple TV plugged into the HDMI receiver for indoor video viewing and listening to music.
What is the best way to transfer Optical into Analog (red and white)
Is it possible to switch from purely HDMI output (while watching video) to solely audio from the Optical port (which would be converted to Analog)
Can this be set up by me, but used very simply for a non-tech savvy woman?

no matter what then depending on the converter you use audio and video could very easy get out of sync

2 different "switchable" audio output (HDMI and analog) with Mac mini

Hello,
I have a 2010 Mac mini that I use as a media center. Its hooked up to my HDTV in the living room via HDMI. I also want to hook up external speakers via the 3.5mm analog jack. These speakers are in the kitchen.
I would like to get my audio through HDMI when I watch TV and be able to get audio output via 3.5mm jack when I just want to listen to music in my iTunes library. I like to control my iTunes library with the Remote app on multiple devices.
Is it possible to switch automaticaly the audio output?
Right now I use my Airport Express to stream music from my Mac mini to the speakers but I think that the Airport isn't really needed since it lies just by my Mac mini. I'm pretty sure the mini can do both.
I've tried to hook the speakers to my Mac mini but first: I hear a "hum" in the speakers (wich I don't hear with the Airport) and second: I can't seem to get the audio out in the speakers.
I've read many posts about the audio midi settings but I can't figure it out...
Any help?
Thanks a lot.

I hit post too early... here's the rest of it.

See the SoundFlower app- http://cycling74.com/soundflower-landing-page/

You can copy an audio stream from one output to another.

Problems with FLAC 5.1 audio over HDMI and mpv

The last mpv update (0.7) seems to have changed the way it gets info about the audio playback device.
Last week, I could play videos with FLAC 5.1 audio over HDMI without any problem. My .asoundrc was just:
pcm.!default {
type hw
card 0
device 3
But after the last update, if I try to play a video while the default pcm device is set to HDMI, I get this error:
mpv: ../audio/chmap_sel.c:89: mp_chmap_sel_add_map: Assertion `s->num_chmaps < (sizeof(s->chmaps) / sizeof((s->chmaps)[0]))' failed.
Aborted (core dumped)
I tried downmixing, since the problem seems the number of channels.
I added this to my .asoundrc:
pcm.!surround51 {
type vdownmix
slave.pcm "default"
pcm.!surround40 {
type vdownmix
slave.pcm "default" {
Now mpv starts without errors but I hear no sound.
Everything is fine in mplayer, even without the downmixing in .asoundrc
What should I add to my .asoundrc so that mpv recognises the playback device correctly?

So this is merely a mpv problem.
Good to know, I'll just wait for the update
