Apple TV2 audio won't work on my Samsung LN26a450?

Hey folks,
Just bought an apple TV2 and the video shows up on the screen, but no audio. I have it hooked up via HDMI to my Samsung LN26A450 which is a 720p HD LCD TV. I also own a Sharp LC42D64U 1080p LCD TV and BOTH the video AND audio works on that tv. I'm confused as to why it is not playing audio on my Samsung TV. Anyone have any ideas, solutions, or similar problems??
I have a feeling if I bring it in to the apple store, it would work on their tvs, tell me there's nothing they can do and send me on my way. I don't want to have to carry my Samsung in to get it to work either. The HDMI is a brand new cable that is audio compatible. It works on the Toshiba, not the Samsung, so I don't think it's an issue with the cable.
Thanks!!

All HDMI cables are "audio compatible". The painfully obvious thing to check is the audio settings on the Samsung. Make sure the TV speakers aren't disabled, as they might be if you had been using a receiver. And if you have any other HDMI devices, see if they work with the Samsung.

I just installed Lion 3 days ago, now my audio won't work, unless I use headphones, also space bar glitches, and other software issues..MacBook Pro 15 inch, and most everything is messed,,but the audio is killing me.

I installed Lion a few days ago, ever since then my audio won't work, unless I use my headphones. Also, the saver screen with password changes frequently, and the space bar works when it wants to. There are many other issues I am having. My IPhoto,,does not work properly, pages is not working, I have all versions. The Office Suite is acting strange, and my email accounts work when they want,,,my IPhone 4 won't sync anymore. The list is endless...does anyone else have this problem?

Your wifi problem sounds very much like the problem I had. The wifi would drop out, the icon showed it was still connected. If I turned it off, I couldn't turn it back on. Another user here pointed me to the problem, which was the wifi cable (the flat cable goint from the card to the motherboard). I found it on ebay for $13 and it's been running fine since I replaced it. This is the repair guide for your machine. The part number will be on there if you click the link.

Try:

Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.

Why Apple Thunderbolt Display won't work on BootCamp Win7 64-bit while being plugged to MBA?

Hello,
I have MBA (latest) & installed win7 64-bit in BootCamp, I do also have Apple Thunderbolt 27" Display.
When I disconnect the ATD and re-connect it in Mac OS X, it works fine like a charm, but when I disconnect then re-connect in BootCamp, it doesn't work at all whatsoever, in fact, I have to restart my MBA (while thunderbolt is connected) to make it work in BC, this is the only way to make it work.
So, my question is; If I disconnected ATD in BootCamp then re-connected it, why it won't work?
I've googled everywhere about this issue, but no luck.
Any idea?

to calculate how much video ram is needed one
take
the vertical number of pixels and * with horisontal number of pixels and * with 32bit colour which is 4 bytes
so if it's the 13" macbook air
1440 * 900 * 4 = 5.184MB for main display
+
2560 *1440 *4 = 14.75MB for second display
sounds like the intel hd 5000 would have that as dedicated memory even if the windows driver did not allow to use shared system mem as extra
could be a problem with the driver for windows
maybe a person who ran a setup like yours would have more to contribute with
my setup is an imac 21" with amd video card and a 24" dvi dell monitor and that works fine in windows so it's a different animal altogether

Apple USB Superdrive won't work

I just bought an Apple USB Superdrive. I works fine with a macbook air but if I plug it in to a 15" Macbook Pro either a Core 2 Duo or an Early 2008 model it won't work. The optical disc is not admitted when I try to insert it.
I'm using OS X 10.5
Any suggestions please ?

Ridiculous! I suppose it's all part of the business stategy to force you to upgrade even though the kit you have is still doing everything you want of it.
But I wonder is there a way of doing something in 'Terminal' mode to get other macs to accept the superdrive?

My apple mail application won't work on my macbook, iPad, or iPhone.

About a week ago, my apple mail (aol and google accounts) stopped pulling. They won't work on any of my apple products. It keeps saying unknown error. It will add my contacts for google and calendar, but nothing for AOL.
I have erased my computer and reinstalled the new operating system thinking maybe something was missing (component wise) but it still won't work. I don't know what to do. Please help.

This is what I am seeing on my screen. It won't let me even add a google or AOL account. It keeps saying there is a connection error.

Front facing camera audio won't work (already cleaned speakers and microphones)

so today i attempted to rake a video and was soeaking, but when i went to watch it, the audio was not working, as you could not hear me talkingg, because it was very faint. when i took a video with to camera that faces outward it worked perfectly fine and the audio was clear. i have already cleaned the microphones and speakers. please help! thanks

Did you hold the phone in a different way, using the front camera? Did your hands cover the microphones or do you have a case around the phone?
Does the microphone work if you use the voice recording app?
If your voice is too faint or sounds unclear using iPhone, or iPod touch - Apple Support

If no fix is found.... goodbye windows 10!

[Solved] Pulse Audio won't work on newly installed system with Gnome

About a year ago I got a new computer and more or less retired my old one with my first arch install. Recently, I decided I would set it up as a Linux system for my sister. I first updated the computer, which broke it royally (since it was last updated before the /bin symlinking happened) but I eventually got it fixed. However, after doing that, Pulse Audio wouldn't work, then I broke X and decided to do a full reinstall.
Now, on this clean install, Pulse is again not working. I have set up Gnome and gdm to work, and everything works great except Pulse. The wiki says that Pulse with Gnome 3 requires no extra setup, so I have not edited conf files at all. I have, however, installed "pulseaudio-alsa", which created this conf file:
# Use PulseAudio by default
pcm.!default {
type pulse
fallback "sysdefault"
hint {
show on
description "Default ALSA Output (currently PulseAudio Sound Server)"
ctl.!default {
type pulse
fallback "sysdefault"
# vim:set ft=alsaconf:
which seems fairly standard. Anyway, I tried removing it and had the same problems. When I have Pulse Audio running and try to play sound, I get the error:
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Playback open error: -16,Device or resource busy
which is obviously trying for ALSA, or from mplayer:
AO: [pulse] Init failed: Connection refused
Running "pacmd list" nets me:
Daemon not responding.
and pavucontrol gives me:
Fatal Error: Unable to connect to PulseAudio: OK
when I try to start it.
No pulseaudio commands seem to work (e.g. pulseaudio -k). They don't raise any errors, but also it doesn't have any effect on the server.
The only asound conf file is "/etc/asound.conf", clearing ~/.config/pulse does not fix the issue.
Journalctl does not seem to give anything interesting (Stale PID is the only message when starting Pulse), though admittedly I'm just vgrepping all of journalctl since I don't know how to narrow it down more, nor does the output from pulseaudio -vvvv. There are a lot of errors in pulseaudio -vvvv, but they all appear to be related to loading devices that don't exist, and so I assume not a problem, I can post it if necessary. Sometimes when I kill Pulse the process refuses to go away and I have to reboot in order to clear the process out, but I don't think that's related.
If I kill Pulse or keep it from starting on boot, I can play sound, but only through ALSA, and while I didn't have the problem I expected (I can still play multiple things simultaneously) there's still the issue that the volume buttons in Gnome will no longer work and that the volume levels ALSA reports are basically nonsense to a human being.
I basically just blurbed everything I thought of/found on the wiki or forums, and I'm not really sure where to go from here. It's a fairly old computer, so that could be related, and I'd be willing to dump Pulse if Gnome could integrate well with ALSA, but obviously fixing Pulse would be the preferred option.
Any suggestions on where to look next? I've run out of ideas.
Thanks.

Wonder if you have a conflict between two audio cards ... for example, I have a friend with some PulseAudio problems caused by conflict between the HDMI audio from his graphics card and his onboard sound. Something would switch PulseAudio to the wrong card and it would just quit after getting itself into a twist. Unsolved, I'm afraid, but have a look at commands such as:
aplay -l
pactl list sinks
pactl stat
(Latter two will need PulseAudio coaxed into life first)
and of course, the Arch wiki.
If there is a conflict, blacklisting kernel modules might also be needed.

Bluetooth streaming audio won't work w FORD SYNC after previously working.

Simply pull the SYNC module fuse, then place it back in. This should clear up any problems that anyone is having if your bluetooth audio won't stream or your SYNC keeps saying NO BLUETOOTH DEVICE FOUND. You can also disconnect your car battery cables, then connect them back and this will reset the SYNC Module. I am a Ford Dealer in Southeast GA and had the above problem but just solved it.

IDVD audio won't work after installing Audacity

Can you help please?
I am using iDVD 4.0 and installed a 3rd party audio software, Audacity. That's when the trouble started. iDVD kept crashing when I was editing existing projects, and the audio did not work at all in iDVD. I uninstalled Audacity, re-installed iDVD, and am still getting no audio. The audio files appear within the project, but I just can't hear them.
Is there a preference or other file that needs to be removed to fix this? Any other suggestions would be greatly appreciated.
G5 Mac OS X (10.3.8)

Assuming you've first checked Software Update to see if there are any updated drivers and it's still not working, you could try resetting the printing system.
System Preferences>Print & Scan, Control+Click or Right Click on a printer on the left and select 'reset printing system'. All printers will be deleted and need to be added again.

Audio Won't Work: Help Needed!(SB Liv

Tonight I came to my computer and found that the audio wouldn't work. I ran Creative diagnostics, and the first message was that I needed to "reinstall drivers." The second test failed at hardware check, saying no hardware was detected. So I went to Device Manager and it indicated that it was all there. So then I went to Creative's website to check for drivers, after Windows came up with nothing. I found out that there's nothing. So then I decided to do a "Repair" with my Creative Soundblaster Li've! CD. That didn't work either. Then I just did a "Remove", and oddly enough, when I rebooted, it was all still there. In All Programs, in the task bar, it was still there. But only this time I couldn't run diagnostics again because it said that there is missing information or something. So the removal didn't work properly, and ended up removing certain vital components. This left me one step back!
What should I do? Go into Add/Remove Programs and get rid of all Soundblaster components, or get my Resource CD and reinstall sound drivers from it's Should I retry with the Soundblaster CD?
Note: I also opened up my PC after it was suggested by Creative Diagnostics earlier that I check my sound card's physical connection to my machine. I couldn't find anywhere to unscrew the card, so I just put a light amount of pressure on it to make sure that it's fastened in there properly. It seemed absolutely fine. Although I wonder why I couldn't figure out how to remove it.
Also note that I tried system restore, and to no avail.
I honestly don't know what to do at this point. Can anyone help me?!
Thank you!Message Edited by VenaSera on 02-08-200802:26 AM

MacBook Spring 2010 Snow Leopard won't work with External Samsung Monitor

Hi,
I have a MacBook I purchased about a month ago and it's not working with my Samsung SyncMaster 940 BW. I am using Mini DisplayPort out with a Mini DisplayPort-to-VGA adaptor which goes into my SyncMaster Monitor. I have tried rebooting, and also playing around with my laptop resolution, but otherwise I have no idea what to do about this.
I've read on the discussions that this is a known Snow-Leopard issue but I thought I might post to see if this has been resolved. I run all the updates but the monitor still isn't working?

A better place to post would be in the The MacBook Pro Display (2008 and Later) forum:

Airport extreme, audio won't work on windows 7 boot camp for my macbook pro osx lion

Bought my Macbookpro in late 2011 and osx lion, decided to put boot camp on it, but it won't find my airport exrteme or even if i connect the ethernet cord directly into the laptop it still wont conectto the internet, and my audio also doesn't work, even when i plug in headphones, any suggestions?

Sorry for the late reply, I've searched as much as I could all having similar issues but not quite being the same issue. I've tried manually putting in my airport extreme information, search for other connections, start a new connection, all have not worked. I did everything normally to setup windows except put in the authentication code which i have misplaced.
I might've already added the drivers but im not too sure, how would you add the driver, just in case i missed that part
