Is Optical cable necessary if you have HDMI?

Just got the new Apple TV. If the HDMI is supplying both Audio and Video, is it really necessary to also hook up the Optical? Thanks in advance.

it entirely depends on your individual setup.
if you are connecting the appletv to an amp via HDMI then no, you don't need to use optical.
if you are connecting appletv direct to your TV via HDMI and you want DD5.1 audio, you would then connect the optical cable to your DD5.1 speakers/amp.

Time machine may not be necessary, but some form of backup is always necessary, drives fail, laptops get stolen, etc. Operating without backup is just waiting until you lose your stuff!

Is consolidating library necessary if you have the "copy files to itunes media folder" box checked?

Like the title, Since I've had iTunes I've always had the box checked for "copy files to itunes media folder"... if I want to backup my itunes folder now, do I still have to consolidate the library? I just copied it over without consolidating and it took like half an hour, so I'm just wondering if I should do it again after consolidating? I'm assuming it's fine. It seems to have transfered all 70G of my music.

Sharing,
What Consolidate does is look thru your iTunes library, and for any track that is not already in your iTunes Media Folder, it puts a copy there.
If you have always had Copy checked, and have never moved your iTunes Media Folder, and have not manually put any files elsewhere, then you probably already have all your files in the iTunes Media Folder, and would not need to run Consolidate. However, it would not hurt.

Is magic mouse software update necessary if you have 10.6.8

2009 iMac; OS 10.6.8
I just bought a Magic Mouse and successfully paired it. It seems to be working fine and the system pref is visible and configurable. I've read that one should download and install the software update 1.0. Is that so?

Here are some details on the initial launch of that update. It includes a link but reading the last paragraph my guess is that after OS 10.6.2, the update was probably incorporated into the OS.

Multi-wire optical cable for 150...200 meter connection

Please suggest multi-wire cable to connect switches located ~150...200 meters away from each other.
It is needed to have at least 8...10 wires inside such type of optical cable.

Cisco doesn't sell optical cabling. Typically people have optical cable installed by a cabling vendor from rack to rack and terminated in patch panels.
The recommended specification these days for most intra-building applications is OM 3 or ideally OM4 50 micron multimode cable. You tell the vendor how many pairs you require and they take care of it for you.
You only then need to procure the 1-2m fiber optic jumpers between the patch panel and the SFPs in your equipment. Again these would be OM3 or 4 50 micron multimode and generally you need LC terminations on both ends. They are commodity items and available from any number of online retailers.

Do you have an app or someway to use Firefox on the iPad?

Welcome to the forum!
AT&T is only necessary if you have the 3G version of the iPad. The wifi only version is blissfully unaware of anything called AT&T! Even then, you still wouldn't have to use AT&T to use the 3G iPad, although there's no point in getting the 3G version and not using 3G, is there?
Not only do you not have to be a previous AT&T customer to get the 3G service, but it wouldn't make any difference if you were. You still have to sign up for one of the new iPad 3G plans from AT&T to get 3G service working on your pad. AT&T pointedly refused to allow the iPad to use the 3G service of the iPhone. So having the 3G iPhone doesn't do you any good either. There's no free piggy backing allowed.
Setting up 3G service is very easily done right on your iPad. It's done on a month by month basis (no contracts) so you can choose to skip a month or several months of service, should you like. It's either $30 for unlimited or $15 for a limited data usage version per month.
If your dad's going to get the 3G iPad, make sure there's AT&T service in his area or he won't be able to use the iPad's 3G. The 3G iPad's 3G service will work only through AT&T.

Is there a way to have audio only come through the optic cable and video come only through HDMI on Apple TV 3rd Gen?

I currently have a digital optic cable hook up from my Apple TV 3 to my receiver and a HDMI hook up from my Apple TV 3to my flat screen. The audio is coming out of my TV speakers and receiver at the same time. I was wonder if there was a way to switch the audio output from the Apple TV 3 to the digital optic cable and only have video come out of the HDMI? I really only plan on using my receiver for the audio for my Apple TV 3. I know that I can just mute the TV but I wanted to know if there was a way to switch the feed. Thanks

There is an option on my TV but if I do that I lose all my audio on the TV. I have 3 HDMI ports on my Flat Screen. One is for my cable, one is for my PS3 (BTW the PS3 has an option to switch the audio feed so it will come out of the digital optic cable and leave video for the HDMI), and the last one is for my Apple TV 3. If I switch to external speakers I will lose my audio for the cable. I was hoping there was a way to switch the audio feed on the Apple TV 3.

Cannot display the screen of the macbook on TV. OS is Lion 10.7.2. Connection to the TV is over HDMI cable. TV shows only the backgroud picture of Lion. Do you have any suggestions for help ?

You have the display set in Extended Desktop mode. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.

You will need something such as this:

Ciao.
Note that this will only transmit video. If you need sound, the audio output port will have to be tapped.

Samsung LN52A650 Audio - HDMI or Optical Cable

Hello,
I purchased the Samsung LN52A650 in December and just had it mounted. I keep hearing conflicting opinions in regards to whether or not I need a digital optical cable for the audio or will an hdmi cable suffice? I have a Denon AVR1909 receiver and will be hooking a PS3 to it as well as a 7.2 speaker system. Will my hdmi cable carry the audio that i need? Thanks very much.
Sincerely,
VM The Prince
Solved!
Go to Solution.

Actually, if you are wanting to use your PS3 as a BD player, and want to hear the HD audio codecs contained on BD movies, you have to use HDMI. Toslink won't carry the new codecs.

My apple TV is connected to a DTV with an HDMI cable and to my Yamaha receiver via optic cable. We rented a movie on Apple TV and.found that the movie played, but we only got audio for music tracks. Voice tracks were silent using both TV and receiver.

My apple TV is connected to a DTV with an HDMI cable and to my Yamaha receiver via optic cable. We rented a movie on Apple TV and.found that the movie played, but we only got audio for music tracks. Voice tracks were silent using both TV and receiver. This only occurred on the rented video and on recorded shows on my cable DVR. previews and other content on Apple TV are fine. Any ideas??

Previews and trailers do not contain 5.1 audio.
If you have recently moved your setup, you may have inadvertently changed some of the settings on your receiver. It certainly sounds as though it is unable to play the 5.1 audio from the Apple TV.

No audio with HDMI cable connect - need optical cable?

I have just connected my AppleTV 2 with my Pioneer ELITE 910 HD Plasma TV system. I have a hard wire ether net connected. I have a great picture coming out of the HDMI connection from AppleTV plugged into my ELITE 910 HDMI Media Receiver. But I am not hearing audio. I have gone through the 'settings' menu on the AppleTV screen and have every setting correct (I believe) It might appear that I may have to purchase an Optical Digital Audio Cable that would input into my Pioneer ELITE VSX-54TX receiver (that does have an Optical Digital Input that has not been used.)
Am I on the right track? I was hoping the video AND audio would travel through the HDMI connection. I don't want to spend money on the cable if I don't need it.

Re: No audio with HDMI cable connect - need optical cable?
Yes, audio and video should go via HDMI.
Do other peripherals work ok with the pioneer over HDMI.
My LG BlueRay player works fine. My TIVO works fine -- good audio and video
AppleTV is a bit odd with audio at times.
Does the pioneer media box handle doilby digital and linear PCM?
I don't know what "linear PCM" is. All the specs on this 2004 system are here:
http://plasmatvbuyingguide.com/plasmatv/pioneer-pro910hd.html
If you have Dolby Digital set to Auto I'd expect you to get some audio - if set to On and media box can't decode DD then you may get no sound.
Try cycling those settings as well as the one for audoo bit depth.
Have done all this. Still no audio

Cannot get new Apple TV to send audio to my 2 year old Dennon Receiver, tried HDMI and digial optical cable. Any suggestions?

Just purchased Apple TV. HDMI works fine direct to Sony TV, but want audio through my Dennon Receiver and speakers. Tried the digital optical cable, no sound. Connect Apple Tv HDMI directly to Receiver, no sound or picuture. Ops manual indicates this is suppose to work. Contact Apple support and they offered no solutions? My son has similar system and it works fine via HDMI. What am I missing?

I am far from an expert but recently connected my tv, directv receiver and Apple TV to a Pioneer Surround Sound Receiver and was pleased that it worked. Here are some things I read as I was setting all this up:
1. TV must have an HDMI ARC input for it to support audio. You would connect the HDMI output from the receiver to this HDMI ARC input on your tv. My tv manual , (Sony Bravia tv) did not mention an HDMI ARC input nor was it marked that way on the tv's HDMI input on the back but I used HDMI 1 and it works. If you don't have HDMU ARC, you probably already know you have to use a digital optical connection.
2. Regardless of whether you use HDMI or digital optical connections, there are still some settings you have to make on the tv and receiver for audio. Consult your tv and receiver manuals for these settings.

I am having trouble with the initial connection. I have isolated the problem to the cable/ connection. My new hdmi cable has a resolution up to 1080p...does the resolution matter?is this the right hdmi cable for the apple tv?

There are only two types of HDMI cables (standard and high speed - listen to all 1.2, 1.3 etc etc nonsense they will try to tell in the store) both types will work with the Apple TV.
The cable may be faulty though, have you got another to try, what exactly is happening.
