Bumped - hoping someone can help!

Bumped again. Mainly because, one hopes, the number of users using Thunderolt is on the increase and someone will eventually duplicate and solve the issue. (Right now I know I sit in the middle of a very small Venn diagram.)
Spoken to Apple several times and having ruled out adapters (tried several) and cables (ditto) it really does look like this is about one extra, TV-confusing bit of data being sent out of the Thunderbolt port...

Hi Sorking. I am not sure if you are still having the issue. But, I have the exact same issue. I actually don't think it is data coming from the Thunderbolt port. I think it is somehow coming from the mini display to hdmi adaptor. If I plug the adapter into the HDMI cable (before even connecting it to the macbook pro) it switches my audio to the TV (and jams up my sony CT-150 soundbar so inputs can't change, etc.). When I unplug the adapter sometimes it self corrects (and other times I have to manually change the audio output in the Sony TV menu).
Definitely some conflict between that adapter and BraviaSync.
By the way, the adapter I am using is a Belkin adapter.
Have you had any luck fixing this issue?

Hi. Have had no luck at all! Keep hoping that the latest Thunderbolt adjustment in the OS update will fix it, but no change so far.
So, if ntohing else, it's very interesting learn that this may track back to the adapter. ("Adapters" plural, actually, since I've now tried this with three different models - Kanex, Neet and Cablesson - plus your own experience with a Belkin.) What this means I'm not sure: the implication seems to be that we're out of luck until manufactures make Thunderbolt-specific hardware, rather than for Mini Displayport...

I have exactly the same issue with a Sony TV, a Sony Sound System (Amp/Receiver) and a PS3. Everything was working like a charm for years. I used to use a HP Lapton that I would HDMI connect to the AMP.
I recetly replaced the laptop with an iMac and Bravia Sync doesn't work unless I disconnect the iMac. I had hoped that I can leave the wire plugged in and simply switch the input of the Receiver and have it display on the TV. No such luck. I have a Moshi adapter so add that one to the list.
I am hoping that something will improve but I am not holding my breath on this one.

It really does seem to require eitehr a fix at the Mac end, or for a new adapter to be built with Thunderbolt specifically in mind, as opposed to simply using Mini DisplayPort.
If you're affected, It would help to draw attention to the problem by contacting both Sony and Apple. I have done and although it yielded no result, only by being a 'known issue' - for more than a lone user - can it be addressed at all.
Currently Being ModeratedJan 16, 2012 5:37 PM (in response to Sorking)
I also contacted both, but didn't find many encouraging signs that anything will be done to correct this issue. To be frank, although not pivotal, I would have considered getting a different computer brand if guaranteed that it won't wreck havoc on my set-up.
Anyways, just a quick question:
I went through a painstaking effort to restore the Bravia sync. I was hoping that it would just work, but instead had to reboot the PS3 (after hours of internet searching, a simple unplug of the power cord of the PS3 did the trick)
At any rate, I was wondering if I can in some way disable the Bravia Sinc on either the Amp, or the TV when I connect the iMac and then safely (and most importantly) easily connect it again. This would be an acceptable workaround as I don't need Bravia Sync on the iMac. The only downside would be that I need to physically disconend the Moshi adapter (oh well) when I need Bravia sync to work, which is most of the time as I only occasionally would need the iMac connected.

I would imagine you can turn off the BraviaSync on the TV's menu, use the Mac connection, and then turn Sync back on again once the Mac and adapter are disconnected. But the only way to know if this works without causing a lot of knock-on hassle is to try it!
I've essentially given up at this point. I've connected an Apple TV which, between Mac and iPad, is making it easy to watch most video content through AirPlay. Not a full solution, but suits me needs for the most part.
Still, I'd hope to see this problem recognised and fixed in the future.

I have the same issue here. If you have already found a solution, please tell me.It really doesn't make sense.
Currently Being ModeratedFeb 22, 2012 2:13 PM (in response to Cattapan)
Still no solution. Do, please, report to Apple - link them to this thread - it needs to make it onto their radar.

Same problem here I'm using a cable I bought from amazon and anytime I even plug it in to my BDV-E580 surround sound system it drops out the bravia sync and the tv switches back to the internal speakers. Plugging the cable directly into the tv also makes the bravia sync die also. Really hoping for a solution for this as its highly annoying!

Has anyone been able to solve this?
I'm having the issue with a KDL-46HX755 Bravia... I've tried a "Dr. Bott" mDP to HDMI cable and a "Kanaan" mDP to HDMI adapter with a "full spec" HDMI cable.
Once I plug in my 15" 2011 MBP, the TV reports "TV Speakers active due to Audio System communication failure" and the connection to my sound system breaks down (it's a Yamaha YHT-S401, but it also happened with a Panasonic and a Philips system). The device also disappears from the HDMI device list in the HDMI base setup menu.
At this point, I've pretty much ruled out the audio system and cables/adapters as culprits; it's either the MBP or the TV.

Found a solution!
On your adapter or cable, simply remove or cover pin #13 which carries the HDMI CEC signals; see http://en.wikipedia.org/wiki/HDMI for the pinout.
I did it on my mDP to HDMI cable (which has a plug, not a receptacle, so the pinout is mirrored of course), was a bit of work, but I got the pin removed, and now everything is shiny.
As an alternative, connect an HDMI to DVI adapter to your adapter, then a DVI to HDMI cable to it (so the chain of connections/conversions is mDP-HDMI-DVI-HDMI), that will remove the CEC signals (because DVI can't do that), but keep the audio intact.

Having this exact same problem...really annoying.
All I wanted was to be able to 'plug and play' and here I am...searching the internet for obscure threads on random incompatibility issues. So much for the 'just works' philosophy.
I've just noticed that according to the HDMI 1.4 spec, that officially supports ARC - if I get an adaptor that supports 1.4 spec will it solve this? The one I have now is 1.3b, I think.
