Apple Updates MacBook Pro Mini DisplayPort Implementation to Support Both Audio and Video

flyguyjake said:
No worries ... so PAVP "Protected Audio Video Path" which is the technology used to protect the data (audio & video) path within a computer during playback (e.g. Blu-ray discs). In other words you cannot send loss-less audio (DTS-HD & TrueHD) to your receiver without it. These two audio formats are found on most Blu-ray discs and are superior in sound quality.

Bitstreamming in a nutshell is sending the loss-less audio out via HDMI from your computer to your AVR (Audio-Video Receiver). In the new MacBook Pro's you can now send audio out of the Mini-display port if you use the Griffen adapter Mini-display to hdmi found on Apple's website.

In theory if Apple has fully utilized the hardware with support in it's os & bootcamp drivers then the i7-620m with on-board video & audio would support the PAVP technology and bitstreamming would be possible. But at this time the bootcamp drivers are not utilizing the on-board audio & video so that Windows 7 is not seeing the PAVP and therefore is not able to bitstream the loss-less audio. The boot camp drivers only support the discrete graphics card (Nvidia GeForce GT 330M).

I wish that Nvidia would step up to the plate and incorporate PAP or PAVP into their GPU's so that we can get a more seamless integration. ATI on the other hand has things covered with their 5xxx card series. PAP is supported and these cards natively bitstream using playback software PowerDVD9 or 10 & Total Media Theater 3.

Okay so i understood most of that, but am going to ask you a simple question...well maybe 2...

1. If I install Windows 7, will everything work on the new MBP?
2. If I wasn't too picky on the sound but was picky about just having 1 wire, will sound still work through the mini display port or are the lack of drivers causing NO sound to be passed?

I have the 17" MBP so I can only speak from my experience with it, but I have heard from others that the 15" also works. I'm honestly not sure about the 13". Boot Camp couldn't be easier in creating the Win7 partition and starting the Win7 install dvd. Once you've got Win7 installed then you put in your OS X install dvd and it will prompt you to install the Boot Camp drivers. Be sure that you're using the latest 3.1 Boot Camp drivers which you can also download from Apple.com.

Win7 on the Mac is best with Boot Camp. It runs terrific, in some instances better than on a PC believe it or not. So to answer question #1 yes nearly everything works. As far as sound, if the 13" was part of the mid 2010 refresh that the 15" & 17" got then yes sound will work. If the 13" wasn't refreshed, then I'm not sure. Just call up Apple and they will be able to confirm this for you.

Well the new 13" has the updated 320M graphics card. And i know the old one had the proper drivers. So if the new ones work too, i'm A OK!

Getting my MBP in 12 days!! Can't wait!
 
Confirmed HDMI audio out

Today I received a Mini DisplayPort to HDMI cable from Other World Computing for $19.99 (buy at macsales.com) for my new 13" MBP.

I can confirm that the audio for the NewerTech cable worked perfectly after I changed the Sound output in System Preferences.
 
Just a FYI, you should be able to change the sound output by right-clicking on the volume button in the menubar.

I haven't seen this mentioned anywhere. Does this mean that all those adapters that pass audio through the MiniDisplay Port on the 2010 MacBook Pros will then do the same on the 27 inch iMacs? If the answer is yes then this is great news! :)

May I ask how you know this?

The 27" and 21.5" iMacs already had this, it just wasn't published. Passing audio out the mini-DP connector was a feature added via hardware, it's not something that could show up in a Snow Leopard patch.
 
According to that link this will work with the macbook air that was bought December of 2009. That would be very good news if it is true. I bought an adapter that requires the minidisplay port and a USB for the audio.

Can anyone confirm that the adapter works with audio on the late 2009 macbook air?

The adapter I am talking about that was mentioned above:

Yup I've seen that. But can anybody actually confirm it passes audio on the 27" iMacs? I mean has anybody seen it do so with their own eyes?

I only ask because OWC themselves pointed me towards the adapter with USB audio for such functionality. I'm confused.

Be that as it may I haven't heard of a single person actually doing this with a 27" iMac hence my uncertainty.

This support document only references the following Macs, which leaves me to believe those are the only ones that have support for audio over the mini-DisplayPort connector:
Products Affected:
MacBook Pro (17-inch, Mid 2010), MacBook Pro (13-inch, Mid 2010), MacBook Pro (15-inch, Mid 2010), iMac (21.5-inch, Late 2009), iMac (27-inch, Late 2009)

I wouldn't get your hopes up.

Hello everybody.
It's been told that 21,5 iMac supports audio out through mini Display Port, but have you ever noticed that the 21,5 iMac (the cheaper one) sports a Geforce 9400M?

Well, if it can output audio, then the first gen unibody will do.
The tech doc in apple only mentions the late 2009 iMac but doesn't mention the GPU.
So I find stupid having 9400M that do (the iMac one) and 9400M that don't (First gen unibody MB) output audio through mDP.

What's the point, Apple?

While the Monoprice site for their Mini DisplayPort Male to HDMI Male 32AWG Cable - 6ft says it does not pass audio, I can confirm that it does indeed pass audio to my Sharp 40" LCD from my 27" iMac (W80071Wxxxx).

What I need is an adapter, not a cable. However this is proof that audio does indeed work on 27" iMacs and I already know of several adapters that should work. Thanks for the info. :)

According to the reviews on Amazon, the adapter i posted above should work. I will get mine next weekend, i will let you know if it works.

Lots of conflicting results there and they're pretty much all 2010 MBP results. But still let me know if this works. Thanks. :)

Btw, this adapter appears to be the safest bet, at least for 27" iMac owners like myself. It even claims to support audio in the most recent iMacs in the description.

Yeah, I agree that there are a lot of conflicting results, but i see it this way. The cable is mass produced and sold to Customer A and Customer B.
If A can get it to work and B cannot, and the cable is contant, the only variable is Customer.

Get it?? :D

But yeah, who knows in the end. I will post the result in about a week's time.

Apparently this is something that had to be fixed in hardware, something in the chipset needed to be redesigned to get this to work.

It seems to have nothing to do with which graphics card your Mac has.

Actually is a GPU issue, it's been told before, as the GPU is responsible of the mDP wiring and output signals through it.
