Audio not working over HDMI...

So I purchased an ATV2 and plugged it into my tv (just HMDI) and got no Audio.. Couldn't figure it out, but, I noticed on the back of the ATV that the optical light was shining through the optical port even though there was no optical cable plugged in. Assuming I had a defective ATV (My ATV1 works no problem audio over HDMI on the same TV) I exchanged it today and still have the same problem.
My question is.... Does everyone else's Apple TV 2 shine the red optical light out the back even though you are using HDMI for your audio? Any suggestions on what could be wrong? It's infuriating that this isn't working and I can't find anything to suggest as to why. I know HDMI is working fine as my old AppleTV works without issue..
Thoughts?

Finally got it working. Reinstalled all drivers and still wasn't working, tried windows update since I had 2 intel graphics updates to download. Windows update wouldn't download the updates so I refreshed my computer and my audio worked as well as windows update.

Why can't I get the audio to output over HDMI to my Panasonic TV?

It was working before I upgraded to Lion, but now it doesn't.

Yes. It's my opinion that HDMI is simply flaky. All that HDCP copy protection crap that is carried across the HDMI interface makes HDMI unnecessarily complex. Greedy Hollywood execs impose their bull on a technology that isn't even exclusive to their content, and we all suffer as a result. I've had a lot of problems with HDMI audio - I had to return my Google TV box even though I thought it was an excellent central hub for a media center because it wouldn't pass audio through properly over HDMI. It's a shame the TV manufacturers let Hollywood push them around with this junk. As far as I can tell, all this HDCP stuff only causes problems for consumers, but doesn't deter the professsional content thieves one iota.

HT201210 AUDIO NOT WORKING PROPERLY AFTER INSTALLED IOS7

After installed ios 7
photos not able to see fully
audio not working properly.... [no treble, no depth in sound, very low soung even the volume is full]
get strucks while playing games

This board is full of people that are update crazy...
even when they have perfectly good working systems.
i know i thought well it's just a security update not a major update.
Best advice... whenever updating the OS, unplug all
firewire devices.
will take note of that from now on.
Was this auto-update? Try downloading the file and
running the update again with all firewire devices
unplugged.
While the 828 is disconnected perform the factory
reset
again.
Disconnect the firewire cable from the 828mkII
-Press the Setup knob
-Turn the Setup knob all the way to the right
-Press the Select knob
-Press the Value knob
-Power off the interface and plug the firewire cable
back
in
-Power the interface back on
i have the original 828 not mark 2, so no reset i know of, just power on off.
After the Mac updates... reboot and plugin the 828,
see if that doesn't get you going.

cheers pancenter, i'll give it a whirl updating without the interface plugged in. thanks for all your help.

Laptop left Speaker audio not working

Sir,
I have dv-5 1102 tu model laptop, in that left speaker audio not working. But, in headphones & Speakers have no problem in both left & right audio.
Kindly do the needful

Hey @KKVK ,
Welcome to the HP Forums!
I understand your left speaker is not working on your dv5 notebook.
If the headphones are working it would tell us the sound card is fine. The same properties are applied to the speakers and the headphones in your audio control settings.
You could try a system restore to before the issue started to make sure it's not something in the operating system. To perform a system restore see the following guide: Using Microsoft System Restore (Windows 8) or Using Microsoft System Restore (Windows 7).
If this fails I would suggest contacting HP Phone Support to send the notebook for service. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the following link to get the support number for your region: Phone Assist Worldwide.
Thanks!

Without knowing all of the specifics in your situation, you may want to try these options:
- If you have a DTA, and your remote control has a LANG button on it, press it.
- If you have an HD or SD full cable box:
Most low or no audio issues can be corrected by setting the Optimal Stereo output of the cable box. Here are the steps: Press the Menu button twice on your remote control. Select Setup. Select Audio Setup Under the Optimal Stereo setting, choose "Select to Optimize" and press OK/Select on the remote control
- The audio settings on your cable box may have accidentally been changed:
Press the Menu button twice on the Comcast Universal Remote Control. A new screen below will appear, with the top-left option automatically selected.
Use the down-arrow key (above the Info button) to navigate to Setup and press OK/Select (the center key on the remote control in the middle of the 4 arrow/directional buttons).
Use the down-arrow key (above the Info button) to navigate to Audio setup and press OK/Select.
The Default Audio Track will default to the first option–Channel default–which which is always the channel’s main audio track (unless it was previously changed).
Press the right-arrow navigation key to change the audio track. Changing this selection will instantly change the audio.
1. Press once for English
2. Press twice for Spanish (Español) OR to activate Video Description (DVS)
3. Press three times for French (Français) 4. Press four times for Portuguese (Portugues).
5. Then press the Exit button (above the Volume button) to resume program viewing
Please note: These audio options can only be heard if the program provider or cable channel is providing that additional audio option.
- If the above does not help, look at the remote control for your TV set (not your cable box) as the TVs language settings may have been accidentally changed (sometimes labeled as MTS or SAP on the remote or via your TVs settings menu).

Facebook App not working over 3G, but works over Wi-Fi.

I have a BlackBerry® Curve™ 3G 9330 Social Messaging Ready smartphone. My current software version is 6.0 Bundle 2333. My Facebook application worked perfectly fine when I got the phone a few months ago over the Verizon 3G network and Wi-Fi, but when I recently updated Facebook to version 2.0.0.58, it does not work over 3G anymore. But everytime I try to connect via 3G it says "We cannot reach the Facebook server at this time. Please try again later. (100)" It does however still work over Wi-Fi.
I have tried various attempts to fix it: uninstalling the App and re-installing it and also removing the battery and putting it back in (hard reset), but nothing has worked.
Is anyone else have this same issue? Is there a way to restore my Blackberry to its factory settings so that I can just use the older version of the Facebook App [that was previously installed]?
Thank you.

Hey metalhourse90,
I can see from your PIN that you currently don't have browsing services included in your data plan. I would advise contacting your wireless provider to have this enabled.
Thanks,

I recently moved my library on my time capsule
You mean you moved your music files to the external. The library is more than the music files.
Just copy the \Music\iTunes\ folder from internal to the Time Capsule.
Add the Time Capsule to your Login items in System prefs -> Accounts.
Hold Option and launch iTunes and select *Choose library*.
Select the iTunes library file int ehiTunes folder on the Time Capsule.
It is hte samae library you have previously. All artwork playlists, ratings, songs, movies, etc. will be there.
Genius is already there so nothing needs to be done.

HDMI Audio not working on Q190 (along with all higher level Audio Formats)

Help, I have been given the run around via support, I cannot get the HDMI audio to work with my Pioneer Surround Sound, only the Intel display audio shows in control panel (Win 8 X64) and the RealteK S/P Dif port and it is not capable of supporting 7.1 sound or bitstreaming or DTS, Dolby HD, Etc. Tec support appears not capable of fixing the issue and wanted to send me to software support and pay. I have only had the machine for 4 days and it has never supported higher level sound.
Every other device I have (had or currently) connected to the receiver works just fine. I have to figure this out or return the machine, the audio is the most important aspect for me. Besides when you advertise 7.1 support the machine you sell should be able to do it.

Hey guys,
I have had this Q190 with the Celeron CPU since last week and I am using XBMC Frodo and the HDMI is connected to my AVR Onkyo TX-NR809 and from the Onkyo to the TV. And the sound is 7.1 with PLIIZ. It works fine. I think it may be some driver problem because Realtek Audio which is in the Q190 works fine with the Win8 preinstalled. Realtek is kind of bad with driver because I lost my wifi after upgrading to Win 8.1. After a few days with no wifi, I found out that the driver was bad, yes it was a Realtek wifi driver but posted by Lenovo for W 8.1.
I have another friend who also just bought the Q190 and he reported no audio problem so I think it is just a matter of trouble shooting the drive and configuration. I do love the form factor of the Q190.

(Pulse)Audio? not working (Intel HDMI)

Hi,
so I installed Arch Linux again and have problems with the sound. I think there is a problem with PulseAudio, as test sounds from settings (cinnamon) and using 'aplay -D plughw:0,7 /usr/share/sounds/alsa/Front_Center.wav' work. But when I open music/videos in VLC, Firefox or Clementine, there is no sound, nor are system sounds output.
I tried using headphones and everything works just fine.
I've been searching for a while now and found nothing that could help me. I can't figure out, what's wrong.
Previously I used an AMD graphics card and had no problems with sound and HDMI. Also I can't remember doing something special when I installed and used Arch back then. Now I use the HD3000 graphics included in my Intel Core i7-2600k. I need HDMI because I use an A/V-receiver.
Thank you in advance

There is already a default sink set under ~/.config/pulse, content: "alsa_output.pci-0000_00_1b.0.hdmi-surround-extra1". Don't know what to do with that. I thought it was set by pavucontrol and should be right?
speaker-test -c 2 -t wav -D plug:dmix:"{CARD 0 DEV 7}"
works (while pulseaudio is killed, right!?) in multiple instances, fuser gives
$ fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/pcmC0D7p: iuno 3431 F...m speaker-test
iuno 3486 F...m speaker-test
iuno 3491 F...m speaker-test
/dev/snd/timer: iuno 3431 f.... speaker-test
iuno 3486 f.... speaker-test
iuno 3491 f.... speaker-test
I see no problem there?
I don't really know what you mean with the linked post. But I think a summary might be useful, as I really messed up writing in this thread.
When pulseaudio is killed:
Like mentioned above, speaker-test works with C0D7
VLC with Preferences - Audio - Output module set to 'Alsa audio output', Device set to 'HDA Intel PCH, HDMI 0 Audio Output' works
Clementine with GStreamer Audio Engine - Output plugin set to 'Audio sink (ALSA)' does not work
While trying with ALSA-only I found this out:
$ fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/controlC0: iuno 652 F.... firefox
iuno 4167 F.... vlc
iuno 4259 F.... clementine
/dev/snd/pcmC0D0p: iuno 652 F...m firefox
iuno 4259 F...m clementine
/dev/snd/pcmC0D7p: iuno 4167 F...m vlc
/dev/snd/timer: iuno 652 f.... firefox
iuno 4259 f.... clementine
Concluding Clementine and Firefox use the wrong device. I guess c0d0 may be the default device for alsa? But for pulseaudio it shouldn't matter, right?
Choosing 'HDA Intel PCH, ALC893 Analog Output' as device in VLC results in no sound, obviously, and 'C0D0' in fuser.
However, trying to play back compressed audio with VLC, alsa-only, everything like above does not work. fuser shows the same (C0D7), vlc shows no error playing back .m4a or .mp3 files but it stays quiet.
.oga (vorbis) files I found in /usr/share/sounds/freedesktop do work, though. While VLC is playing, I can't run speaker-test (error: -16,Device or resource busy)
When PulseAudio comes in , some things change, obviously
I'd like to name two states. State 1 meanns sound is working, state 2 means sound is not working. State 1 is default.
First of all, no matter what I do, fuser always gives
$ fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/controlC0: iuno 5552 F.... pulseaudio
/dev/snd/pcmC0D7p: iuno 5552 F...m pulseaudio
Forcing VLC to use 'Alsa audio output'-module, and 'HDA Intel PCH, HDMI 0 Audio Output' as device results in device or resource busy error.
Setting device to 'PulseAudio Sound Server' or 'Default ALSA Output (currently PulseAudio Sound Server)' both work. The 'Module' setting in preferences does not matter. I could either choose ALSA or Pulse with the same effect*. Long story short, audio output works, still not with compressed audio files. This means the state switches to state 2, as long as I keep the .wav file running! -> clementine and firefox also could play back sound, vlc can now also play back compressed audio - as long as I keep at least one of them running. When all sound output is paused, I fall back to state 1. Only playing back a .wav file in VLC or (p)aplay could save me back to state 2. I have to start other apps immediately, when in state 1 as pausing playback instantly causes a fallback to state 1. Opening pavucontrol, while in state 2 keeps me in state 2 as long as pavucontrol stays open. I used this as a dirty workaround for the last days.
State changes are also blocked the other way round. While in state 1, trying to play sound from clementine or opening pavucontrol results as staying in state 1, also when I play a .wav file with vlc.
Sorry that was much text, but I hope it's clearer now
*correction: This setting needs a restart of vlc to take effect. When the 'Module' is set to ALSA, pavucontrol lists 'ALSA plug-in [vlc]: ALSA Playback', when set to pulseaudio, the entry is called 'VLC media player: audio stream'. Same for clementine, when I change from ALSA to pulseaudio in the settings. Firefox always uses ALSA. However, it does not have effect on the state-thing. I still need to enter state 2 with the methods mentioned above

Can someone help me out here?
Thanks!

I've a DV4 and I did get it to work many months back; and have not done it since. If I recall correctly, I had to resort to JACK. YMMV
