Ah, that would require too much manual work to switch control panels. Does your TV have stereo analog out? If so, then why not use that? You will need to leave your TV on to listen to music.

If you stayed with HDMI, you would need a splitter to enable the above scenario as Y cables do not work.

And, these boxes have XBMC installed with an embedded linux os, so no windows. however, I do have options to change the audio to differnt outputs, and change it to analog, it just isnt' as robust as windows.

Understood .

I can envision my wife watching TV and me listenign to music, so the TV would need to be available for regular use. I would rather not have to have the TV on to listen to the music. Works in theory, but won't be practicle for us.

I could potentially do a usb solution like you mentioned, I would just ahve some usb speakers for when streaming movies, then some sort of matrix for when i want it to go to outside opposed to the "tv area". I am not familiar with any sort of unit that would do that, and not sure if I love the idea or not, but I'd consider it. Part of the problem there is wife proofing, volume up and down is on the remote now, that way it would be on our phone.

Oh, your scenario is very complex then and couldn't have been solved with HDMI easily anyway. If your PC has only one HDMI and you are watching videos with that, how would have gotten different audio (music) to go to the other speakers?

If your media player in Linux lets you specific an output device, then the USB connection might work quite well. Set that to USB and let XBMC use HDMI.

Alternatively, and probably much better, is to use a networked solution with a streaming audio device. Share out your media and then let these devices "pull" the content from your PC over the wireless network. Squeezbox is a popular solution as is Sonos: http://www.logitech.com/en-us/speake...-music-systems

These devices often come with amplifiers built in simplifying your life altogether Yes they will cost some money but you get cool features like local browsing of content on the remote device/remote control. This would be disruptive otherwise as you have to stop what you are watching on the TV to decide what to play next on the PC.

Anyway, food for thought .

Maybe hook them up with a old school crystal radio set, and a Carbon speaker, or even better, just go old skool with a carbon mic & electromagnetic earpiece. Then maybe it would work.

with a carbon earpiece.

they made carbon mocrophones, not speakers...try to keep up.

Try as I might, I have yet to make our entertainment systems "Wife Proof". It is a noble goal but most often unachieved.

Headphones require a fraction of the power that speakers need. And believe it or not, there is a tiny little amp that puts out that power to every headphone jack.

Any speaker needs a power amp of some sort. Sometimes they are built in, and not very large (computer speakers, for instance), but they DO need power. The one exception are certain VERY small speakers that will play off the headphone output, but they don't put out much volume at all... more than a couple feet from the speakers and you won't hear anything.

Studio monitor-style speakers are also self-powered. They have a plug that need to plug into the power outlet, in addition to the signal cable, and an internal amplifier. There's that amplifier word again.

Outdoor speakers are also often self-amplified, but again, that's an internal amp that needs to be powered somewhere (be it solar, AC power, internal batteries that need to be charged regularly, etc.).

Again, as a general rule, the only speakers that can work off the pathetic trickle of power coming from a line-level output are headphones, and that's only because they don't need to project sound more than an inch. Anything more substantial must be connected to an amplifier somewhere in the chain. And HDMI is not an amplified signal, it's digital.

Thanks for all the replies guys. With all the new info, it might be best to change my question:

How to take hdmi from htpc and output sound to an outdoor speaker, powered or not powered, I do care, can do either. However, the conversion must by small in physical size, and no more than, say, 50 bucks. Quality isn't important, as all I do now is put pandora on my iPhone and blast it / hook up the headphone jack to outdoor speakers currently.

Sonos would be my pref, but the wife botched that due to money.

I'm digging the little amp given in a previous post, good size and money.

It sounds like you have your TV distribution pretty well figured out and you really need to get the Audio for music listening brought to the same level.
Since your main source is centered around XBMC, you might consider purchasing an Apple TV box. You can Jailbreak the Apple TV so that it will allow you to stream both audio and video to it. Just do a search on Google for XBMC to Apple TV. At least it would fit your requirement of controlling everything from your iPhones. If you used iTunes as your music source, you could also use the Apple Airport Express which gives you wireless connectivity and also has a 3.5 mm Audio Out jack to connect to a stereo and can be controlled from the iPhone with the Remote App. I use this for my outdoor speakers but they are part of a separate AV Receiver that drives speakers outside.
I think what you want to do is feasible however it will likely require some funding. As mentioned by numerous others, HDMI is not going to be a good solution since its signals are digital and won't drive headphones or speakers without some processing. Your best bet since you are using PCs is to do your signal distribution wirelessly and then use a box like Apple TV to get it back to the Analog format that can be amplified by a stereo system.

Looks like I was writing while you were posting.
Trying to use HDMI is really going to be a problem. It is not meant to connect directly to speakers. It is a Digital based system with Handshake designed to be connected between a source and a High Definition TV, Monitor or AV receiver.
post #41 of 51
Both Apple TV and Apple Express Modem are less than $100 but more that $50. Both have line outputs that might drive your outdoor system similar to the level your iPhone does but clearly that is not what these outputs were intended for. A line output is a high impedance output and it is not meant to source much current. A headphone output is typically a low impedance output so there is some current available to drive the headphones and in some cases as you have noted, it can drive small speakers.

A typical consumer level line output has a source impedance of less than 100 Ohms...this is a low impedance.
post #43 of 51
You are right Sam64. I was thinking in terms of them typically driving high impedance inputs but the output impedance is around 100 ohms. (My bad) Typically the line level is an Op Amp output so putting an 8 ohm speaker on it comes close to shorting it out. Whether there is enough current to drive the OPs speakers is probably questionable as headphone outputs typically have some sort of Audio Amp even if it is just a few hundred milliwatts.

I've thought about the Apple TV route, but it just seems unnecessary. I already have the PC, which I would think does everythign the apple TV can do, and more.

I do understand that HDMI straight to speakers will not work, that was my original hope, and reason for the thread.

I also understand now that my next thought, headphone out or line level out to a speaker will work, it just won't produce enough sound, or work at all pending certain speakers.

But, I do know that line level out / headphones out paired with these speakers:

http://www.google.com/products/catal...=0CIABEPMCMAA#

work, as this is what I currently do a lot of the time. The above link isn't exactly what I have, as I don't have the ipod dock, but it is the same. It is powerd, has a built in amp, and should, if I am readin gyour guys suggestios correctly, work with what I want.

Now, the problem still exists of getting one "output" from my htpc to drive sound to multiple locations. 1st location is the TV, this is already done just by the hdmi to the TV. 2nd is, somehow, to convert hdmi out down to analog to send the signal to the above speakers as an example.

Since those speakers have built in amp and everything needed to power the speakers, I think, then all I need is to get the signal to the speakers, or rather the wireless unit which transmits it to the speakers.

I was trying to avoid using those speakers just because they aren' the most attractive solution, and was looking for a flush mount speaker, but I am ok with using these.

So, is there any way to go from HDMI to the above speakers, without the use of an AVR.

If not, then I'll just plug in the line out every time I want to use them, it's a pain, but I know for a fact it will work, as I have done it many, many times.

HDMI to speakers without AVR won't work. You have to use the 3.5 mm output from your computer to get Analog audio and then that can be sent to speakers. The advantage of using the 3.5 mm output is that you should be able to send a video + Audio via HDMI to your TV and send a different audio signal via the 3.5 mm jack.
At this point, you are beating a dead horse trying to use HDMI for speakers without an AVR.

How about running optical to an inexpensive DAC where the powered speakers are? It means doing the switching on the HTPC though, between HDMI and the optical.

Hi,

Came across this thread whilst researching a similar conundrum
It seems to me that in this case the simple solution would be to run the audio out from the PC to both HDMI and audi at the same time
If you are running Windows 7 this is quite straightforward to do

How to output audio through HDMI & audio simultaneously

Hope this is of some use :-)

Maybe I missed it, but what about an HDMI Audio Extractor / Converter ? These generally run about $50 from various sources.
