Having problems choosing sound output through HDMI to my television, any one any ideas?

Though listed in the sounds options, I can't seem to choose a sound output to my TV through HDMI. I have sound output to headphones via the headphone socket or usb, but when I highlight to the HDMI TV option it justs returns to the top of the list, any ideas anyone?

About alsa dmix, and for the record:
On an Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz, the following are my finding about
quality/cpu when mixing two streams at 44khz:
a snippet from my .asoundrc
#converter "samplerate_best" # perfect: 16%cpu, maybe overkill
#converter "samplerate_medium" # almost perfect: 6%cpu
#converter "samplerate" # good: 4%cpu, definitely usable
#converter "samplerate_linear" # bad: 2%cpu, way better than default wine resampler
#converter "samplerate_order" # very bad: 2%cpu, like the default wine resampler
Here is the reference topic: https://bbs.archlinux.org/viewtopic.php?pid=942724
I may be wrong, but in an opensource world (code reusing), i really doubt pulseaudio could lead to better quality/cpuuse tradeoff.
Pulseaudio, being just another layer atop of alsa, could only lead to higher cpu usage.

When I connect my Mac Mini 2011 with Lion to a TV via HDMI and an earphone cable is plugged in, it´s not possible to choose sound out via hdmi, as opposed to connection via minidisplay port. Anybody knows how to fix this?

Was just on the phone with Apple about this.
The solution was as follows for me anyway...
Go to your Finder
Choose the Go Menu
Choose Computer
Choose your Macintosh Hard Drive
Choose your "Library" Folder
Choose the "Preferences" Folder
There should be a folder called "Audio"
Move that whole folder to the trash
Empty the Trash
Restart from the Apple Menu
When you are back up and running;
     Choose System Preferences from the Apple Menu
     Choose Sound
      In the output tab you should now be able to make the HDMI "Sticky"
      Enjoy your sound over HDMI and no more dirty knees or broken backs unplugging the desktop speakers!

Sound Output Through miniHDMI port

I am trying to link my 13 inch MacBook Pro to my tv so I can watch videos I have on my computer on my TV. I have the mini HDMI cable converter hooked up. I am getting video from the computer to the TV but no sound. I tried a headphone to RCA converter to get sound to the TV and this works if I have the TV source set to AV. However this only sends sound to the TV and not video. And the way the TV source works I cannot select HDMI video input and av sound input. Is there a way I can force sound output through the miniHDMI cable so I can get sound and video through one cable? I would greatly appreciate any information and help anyone can provide.

HT1657 I am having problems with sound in my rental movies

We rent movies all the time but lately we are having problems with sound for our movie rentals. We watch the first half hour without a problem than the voice is choppy all the time. Sometimes it is good for five minutes than noting for a while. We have tried everything we could think of with no avail. I could see one movie but the last 5 or so have been the same. Done trying we need to fix this! Help! Any ideas?

First try resetting your iPad by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears. Try again to see if the problem persists.
If you still have the same issue, it's possible that something is lodged in the earphone jack. This can cause the iPad to think earphones are plugged in when they are not. Use a vacuum to try to suck any dust, lint or other foreign matter from the jack. If that still doesn't work, try CAREULLY using a toothpick.

Help with sound output via HDMI

My sound output via HDMI suddenly stopped worked to my TV set. I've reset the PRAM and the SMC. When I go to sound control panel for sound output, the setting is on Headphones. When I try to change it to SV420XVT1A (the tv) it immediately jumps back to headphone. I also tried a different HDMI cable to a different HDMI port on the tv. This just started after the Mac Mini had been turned off for a week. I'm using Lion and it's an 8GB Intel Core 2 Duo. Any suggestions?

I actually discovered this answer about 5 minutes after I posted the question. Thanks a lot for your help!! Funny thing is that it had worked all along with something plugged in the headphone jack but suddenly stopped working. Again, thanks!

There's a good chance that this is a known issue. We'll have a Flash Player 18 beta later this week that should resolve this at http://www.adobe.com/go/flashplayerbeta/

Sound Outputted Through Internal Speakers is Distorted While Charger is Disconnected

I have a new Pavilion G7-1263nr that works great while the charger is plugged in. When I unplug the charger sound outputted through the internal speakers becomes distorted, and the mouse response is erratic.
Thanks for the help!!

Hi Giraut,
I don't have such a device to check, nor even external speakers, but I suspect this invisible file is corrupted, I'd drag it to the desktop and see if you can set it again...
/Users/YourUserName/Library/Preferences/ByHost/.GlobalPreferences<12digitHexNumb er>.plist
Might check Midi Setup Utility to see if it's set for 44.1K also.

Hi all, I'm still having problems with my security questions as they were not the ones I answered. Now I'm confused

Hopefully one of these steps should solve the problem.
1. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
2. Reset PRAM. http://support.apple.com/kb/PH4405
3. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
Best.

Concurrent problem-can any one give idea 4 my assignment?

Create a GUI program to trace out any braces and keep track of the line having wrong closure of any
braces dynamically and identify the previous line typed if error prone note some red symbol in the
marigin. The marigin however must dynamically increase the line count of the coding.

Linux 3.2 sound plays through HDMI and laptop speakers simultaneously

As topic says, laptop speakers is not muted when activating sound through HDMI. Downgrading to 3.1 solves the problem. The laptop is an Asus UL30a.

Are you using Alsa or PulseAudio to configure your audio settings? The Arch Wiki has extensive tips for both. You might need to set a default audio output

I am using Pulse Audio (and KDE). It's all correctly setup, it has been working for several months and it works if I downgrade kernel to 3.1, so it's a regression with the new kernel. Also, if any mods are reading this, maybe thread should be moved since 3.2 is out of testing.
Edit: It's quite weird. If I go to KDE sound settings and change them around a couple of times, after a while it works like it should. There is no consistency in this and I have no idea how to troubleshoot
Edit2: Could this be related? I know it's for Nvidia cards, but in the first comment he mentions hda_intel.chttps://bugzilla.kernel.org/show_bug.cgi?id=42567 I should probably have mentioned in the first post that my laptop is all Intel:

TS4113 Mac mini looses audio output through HDMI after being in 'sleep mode'

Since a month or so, my Mac mini is unable to send audio through HDMI output after being in 'sleep mode'.
Recently this was no problem, but now I cannot hear anything after unsleeping (unless I reboot fully).
Please help.

This is not just a Mac Mini problem. I've found comments from people with all kinds of Mac, with any kind of external sound device, who all have this same issue.
The common factor is Mountain Lion.
Apparently there is a new build (12F42) which is supposed to fix this.
http://www.gadgetguide4u.com/new-os-x-1085-build-number-12f42.html
Apple released it to their employees on the 25th Sept.
Here's hoping that build is available for the rest of us soon ...

Satellite R830 and video output through HDMI

Just wondered if it's normal for my laptop to output a max of 1280x768 through HDMI to my 26" LCD TV?
Its a Satellite R830 i3 with hd3000 graphics. I have 8GB RAM. Tried under Windows 7 and 8 but the same.
Also tried custom resolution but it just says on the TV out of range.
Mt graphics driver is up to date and I had full hd working on this TV via another older laptop.
Any suggestions please?

I dont know your LCD TV specifications but fact is that external resolution depends on three options:
graphic card driver, graphic card and the external device connected to notebook/computer.
So if your TV does not support an higher resolution, you will not be able to choose another resolution.
If your TV supports higher resolution but the graphic card driver and graphic chip would not support higher resolution, you will also not be able to use it.

Having problems choosing sound output through HDMI to my television, any one any ideas?
