If this was a little cheaper and I knew it would work flawlessly I'd say it was a good option.

Not really sure why it's so important to carry audio via HDMI.. Digital audio out with $5 TOSLINK cable has the same end result..

Does the usb allow you to output multichannel LPCM or the HD audio codecs? If not, I don't see see the point of using usb instead of toslink

The main reason I think, some TV's dont have TOSLINK inputs, or they ignore the audio coming in from the RCA inputs (in other words they look for the audio in the HDMI cable).

If you have a receiver (home theatre - surround sound) of course you don't need this as it most likely has SPDIF.

Anyone know the technical advantages/disadvantages between toslink and this adapter? Aside from the 1 cable instead of 2? Audio formats/quality etc.

Don't there's any advantage. This adapter is mainly aimed at those who don't have a Home Receiver who connect to a TV only.

Reviews of the adapter have confirmed that it is just the toslink audio added to the HDMI video signal. So: no HD audio codecs, no additional audio formats supported and no streams beyond 1.5Mbps. This adapter just gives you the benefit of a single HDMI connection to your display or receiver that carries audio and video instead of the 2 cables currently required to do the same.

Unfortunate news :( And its pretty pricey considering all it does is put the audio+video onto a single HDMI connection.

I have a miniDP to HDMI cable connecting my MBP to my HDTV (LG 32LF11).

What is the best option for audio? Should I buy 'Mini Displayport + USB audio to HDMI Adapter' or will a toslink cable work? I have no idea if my TV has toslink option.

My TV audio specs :

Audio System
Speaker(s) 2 x Right/left channel speaker - Built-in - 10 Watt
Sound Output Mode Stereo
Surround Mode Yes
Sound Effects SRS TruSurround XT
Audio Controls Bass , Treble , Balance , Sound mode

I think the most practical option for audio to the TV would be to simply use a stereo mini-plug -> 2 RCA cable to connect the analog stereo signal from your mac to the TV.

My 52" Samsung LCD (LN52A650) doesn't have a toslink input (only an output). All the non-HDMI sound inputs are analog stereo. I'm guessing that's pretty typical, even for high-end TV's. There isn't much need for a multi-channel digital audio input on the TV since it only has a single pair of speakers.

Once again, I think that fancy adapter simply improves aesthetics by providing a single-wire connection to the TV.

Thanks a lot! I finally ordered it. I don't care about digital audio really given that I will be watching streaming video for the most part. I just saw the dolby logo on my HDTV and thought Toslink would do good but my TV has no toslink input!

according to the specs this cable is supposed to support LPCM and DTS MA/Dolby true HD.

I find that hard to believe since it gets the audio from the mini-jack which I didn't think supported those audio formats naively. Someone chime in if I am wrong..

That Kanex adapter is interesting if it actually works per the specs. I would guess they are pulling HD audio or LPCM passthrough via USB and adding it to the HDMI output. Their online guide refers to the digital output as JBaughb says but the optical out on Mac's is currently limited to DD 5.1 or DTS 5.1 at up to 1.5mbps in OSX. And, as far as I know there are no HD audio codec drivers for USB audio connections under OSX either - stereo only. Maybe they have written their own digital out driver? or USB audio driver...? Or maybe the HD audio functionality is only supported under Windows?

What excites me about this adapter is how it will allow me to select where my Mac audio is outputted to (the speakers connected to my Mac or the speakers on my HDTV) with just a click of the mouse in the system preferences.

I'm still using a first-generation 24 inch iMac but I'm planning on getting a new iMac probably soon after they come out, whenever that might be. My iMac and HDTV are in different rooms but they are on each side of the same wall. So what I'm planning on doing is drilling a small hole in that wall and connecting them with this adapter. This way whenever I want to watch some streaming content, surf the web, play some games, or do just about anything on my iMac I would then have the option of doing these things in the comfort of my living room on a screen that's twice the size of my iMac's if I choose. It would also be a better way to show off slideshows, videos, and so forth to visitors and friends. I already have an iPod touch 2G and an Airport express so I could use one of those air mouse apps as a controller. If really necessary I could buy a Bluetooth mouse and keyboard.

I realize that a Mac Mini is the most popular way to go for this kind of thing but doing it that way would cost quite a bit more and I really don't feel like having to maintain two computers. More importantly, I don't really know how much I'm going to use this option so therefore I look at this as an inexpensive way to try it out.

One final note. I'm disabled and would be unable to constantly unplug and plug in audio cables depending on whether I want to use my iMac by itself or go out into the living room and use it on the big screen HDTV. Therefore the advantage of being able to pick where the Mac audio is routed with a click of the mouse becomes obvious for me. Maybe there's another way to do this just as easily without this adapter but I don't know what it is.

I can't wait until I can do this! :-)

I am hooking my 47" 1080p LCD tv to my aluminum MacBook. I have a MDP>VGA adapter that I have used to connect the tv to the MacBook at 1920x1080 resolution. How much difference would there be with this MDP>hdmi adapter over VGA?

In terms of video I mean. I understand that this would reduce it to one cable rather than 2 when considering audio.

The signal when coming through HDMI vs VGA is way better. I can easily see it on my 32" 1080p Samsung. It's great. I connect an HDMI and a Dynex Y RCA cable for audio. It's fine enough for me considering that I do not play Blu-ray rips and Mac OS X doesn't support Blu-ray playing.

Using a mDP>HDMI like this would also allow you to maintain the HDCP chain - ah DRM, how we love you <sigh> Given you have an Alum MacBook, you cannot watch HD DRM'd content over VGA currently - it will give you an HDCP error. This will only affect DRM'd content though, so BD rips or anything you converted yourself will work fine, just not legally purchased HD content; ie: iTunes HD TV shows or Movies as an example.

I apologize for the caps, but I feel it is required...

DO NOT BUY ANYTHING FROM THAT COMPANY!!!

I bought this adapter because at the time their product page said it supported uncompressed audio formats. After purchasing the cable, they snuck a little blog post on a subsection of the site stating that it did not. Over the weekend, they quietly changed the page to no longer reflect the uncompressed audio comments. I submitted a complaint to their site that was admittedly not worded very politely (no cursing, just complaining about being "duped" by their poor wording) and requested a swap for the USB+HDMI only model or a refund. They have refused, so I am now going through the process of filing a Better Business Bureau complaint to see if I can recoup my $78 after shipping. I'll be lucky if I see a single penny back and now I have to pay $40 to get a functional product from a reputable business (Monoprice.com is awesome and I should have known better!). Needless to say, avoid at all costs!

I wish I checked a little better when I ordered my displayport to HDMI cable last week from Monoprice. I would rather have gotten the one that supports audio as well. Currently I use an iMac to record TV shows. I send the video to the TV and audio via TOSLINK to the receiver. I would prefer to remove the received from the equation and just got both video and audio to the TV.
Oh well, if it get's positive reviews I'll go ahead and order one.

That sucks, they should at least offer you a refund or credit. I think the other Kanex USB+HDMI model is even worse so I don't think you really want that... it's only two channel audio... not even 5.1.

BTW, this won't make you feel better but it's a long standing fact that Toslink optical doesn't have the bandwidth to support the latest HD uncompressed audio standards so what made you believe they had somehow magically solved this problem?

I'm definitely curious to hear some reviews of the monoprice adapter... no driver required for multichannel audio output?

Well, I can think of two reasons.

1. Some folks like to keep the number of cables to a minimum.

2. Not everyone has HDMI ports that accept auxiliary audio inputs.

Sorry to hear that Osip :( So it is as we guessed and they do not actually support HD audio codecs. So, the only real benefit of an adapter like this is to have audio and video on a single HDMI connection - a fair offer except that the price is Very high IMO considering this is the only gain. Ah well, sorry you had to be the lab rat to find this out... but you have saved the rest of us some $ so I thank you.

Hey,

I wonder if it would be possible to use my LED cinema display with a PS3 if I use the new cable from monoprice ? Behind the back of the Cinema display, there is a single connection cord that splits between a usb wire, a mini displayport and a magsafe to recharge my 13 inch unibody macbook. On my ps3, there is an HDMI entry.

So, what do you think ? I must say that I am completely lost...

I'm not familiar with the outputs of the PS3, but even if the adapters worked, how would you get your audio?

I'm guessing that it won't work. Not sure if the Apple LED can take a 1080p signal.

I wish I had seen that earlier... I ordered/received the Monoprice one - Keep reading for that experience...

I knew this, actually. I was hoping that the USB portion of these adapters would be for more than just power. On the Mini Displayport+USB+Toslink adapter, the USB is power only - A fact that Kanex did not initially state on the product's ORIGINAL page. The product page went so far as to state that it passed uncompressed audio formats such as TrueHD. It has been modified since to reflect the fact that it does not do this.

Sorry to hear that Osip :( So it is as we guessed and they do not actually support HD audio codecs. So, the only real benefit of an adapter like this is to have audio and video on a single HDMI connection - a fair offer except that the price is Very high IMO considering this is the only gain. Ah well, sorry you had to be the lab rat to find this out... but you have saved the rest of us some $ so I thank you.

$100 and I have to say that's a small consolation. ;) Thanks for the sympathy, though. I haven't given up on the Monoprice adapter as I'll discuss at the end of this post, but I have shoved the Kanex one into my laptop bag for now.

I'm not familiar with the outputs of the PS3, but even if the adapters worked, how would you get your audio?

BINGO! I doubt the 7.1 uncompressed audio would make it through this exchange.

I'm guessing that it won't work. Not sure if the Apple LED can take a 1080p signal.

The LCD will just upscale it to the max resolution as it would any other signal fed to it. I'm sure it'd take the video, but at the loss of the surround audio.

And now, the next ordeal...

I'm definitely curious to hear some reviews of the monoprice adapter... no driver required for multichannel audio output?

I was out of town over the weekend, so I just now started playing with the Monoprice Mini Displayport + USB adapter. In Snow Leopard, it's 2 channel only. In Windows XP, the same. I'm thinking/hoping that this is merely a driver issue that can be resolved by some resourceful soul out there. Windows XP is installing generic USB Sound Card drivers for the adapter, which leads me to believe that this might be possible. I'm trying to download versions of the Realtek HD drivers to rig this and I'll keep you all posted.

It has been some time since I looked for miniDVI adapters but, I thought monoprice used to carry a miniDVI dongle like this.. It had a mini toslink plug and miniDVI that went to a female HDMI input in a box-like looking thing. Sorry - I'm going from memory here as I can't find a link to it any longer but I hope that helps...

Also thanks again Osip. I have seen external USB audio devices that offered HD audio codec support under Windows so (I'm guessing) you might be right and there may be a driver you can use that would enable pass through for multichannel and maybe even HD audio over the USB port. whether this would still work over the single HDMI connector though is anyone's guess.

This USB to HDMI Adapter (http://www.espow.com/wholesale-usb-multi-display-adapter-for-computer-add-on-a-second-monitor.html) is only to give you a single HDMI connection to your interests, display or receiver, with audio and video, rather than two need to do the same cables. I think the audio to the TV the most practical approach is to simply use a stereo mini-plug - "2 RCA cable to connect from your Mac to the TV analog stereo signal.

I know that the Mini USB to HDMI Converter (http://www.espow.com/wholesale-usb-multi-display-adapter-for-computer-add-on-a-second-monitor.html) is the most popular way to go in this kind of thing, but doing so will take quite a lot, I really do not think they have to maintain two computers. More importantly, I really do not know how many I would like to use this option, so I will see it as an inexpensive way to try. Therefore, the split would send to my iMac, and my TV speakers while other provisions of the iMac's audio is a set of speakers?

Speakers will be a set of high-definition TV, in fact, one of my subwoofer to. Those speakers bass speaker and subwoofer plug is inserted the other side of the split. As you mentioned, I just want to shut down high-definition television speaker when not in use.

Hi !

Using this:

http://www.wesellbargains.com/dvisdicotoau.html

It works nicely, combining DVI + toslink-audio to HDMI and it also outputs the toslink so I can still use it for home theater receiver.

I have Mac mini and HD-Ready TV 1366x768 connected from mini-DVI through this and Sanyo Z4 projector connected from displayport with HDMI-adapter,

Only disadvantage is that device don't have 1366x768 resolution so I have to use 720p, 1080i, 1080p or 1344+756 in HDTV wich are not natural resolutions of the panel.
