hdmi sound problem began after 10.7.2 update

Since I've applied the latest update, I am no longer able to switch my audio output from headphones to HDMI. I change between the two on a near daily basis. I hadn't previously encountered this problem with any 10.6 or the previous 2 releases of Lion. I have a Panasonic TV. Whenever I click to change the output from headphones to hdmi from either the top bar sound icon or through settings/sound it reverts right back to headphones...

Just did some more troubleshooting. If I unplug the minijack from the headphone jack the sound starts playing on my TV via the HDMI after OSX removes the line out option to show internal speaker. As soon as I plug the minijack back into line out, the TV audio stops and the software sound panal automatically jumps back to line out. Remain unable to change to HDMI through software while minijack is physically plugged in. Repeated several times. Can only switch to HDMI audio out while the minijack plug is physically removed from the headphone jack on my 2010 macmini. While this offers a temporary work around, it is quite annoying.

This ia happening to me as well. I've tried messing with the MIDO settings but nothing works. When I try to select the Samsung TV (HDMI) audio out it just reverts back to my Headphones. This happened after the 10.7.2 update and was working before that just fine.


This happens for all audio, there is no way to select HDMI output anylonger, it just reverts to Headphones.

Jzaun,


Is there anything plugged into your headphone / audio-out port ?


The behaviour I am seeing is that if there is anything connectd to the headphone / audio-out port, it is impossible to select HDMI in System Preferences -> Audio, however applications which are able to select an audio destination are abe to send audio to HDMI.


If anything is plugged into you headphone / audio-out port, unplug it and let us know if HDMI then becomes selectable ? This information might help Apple track down the issue in a more timely fashion.

Those with no audio at all, do you have 2010 or 2011

Minis or something else? Reason I am asking, is that

I have updated my 2010 to 10.7.2 (hoping it fixed iTunes

movie issues, didn't) and have had no change in my

audio performance. My configuration is:

Mini->Yamaha Receiver->Samsung TV.


I know in the past, trying to debug some other issues,

having the HDMI and optical connected at the same time

defaulted to optical out and could not get HDMI audio.

It seems that deep in the Hardware/Fimware/LowLevelDriver

there is some link between the two and probably the original

designer is gone and the people working on it now are

clueless as to how it works.

Not sure if this is re4lated but it does sound like there are audio issues (i've posted this in iTunes discussion)


Prior to the latest upgrade of iTunes I was happily streaming audio from my MacPro to my Apple TV and then over my sitting room speakers. Now if I pause the audio in iTunes for any lecgth if time (when i take a phone call for example) and then start it up again, do audio is heard. iTunes is playing, the Apple Tv is still on. I have to switch back to computer speakers and then back to AppleTV again to reactivate it.


Is this me, iTunes 10.5 or Apple TV iOS5?

I too am noticing this problem with my 2010 Mac mini. It only started for me after upgrading to 10.7.2.


My Mini is connected to an AV receiver via HDMI. When waking the Mac from sleep to play music the sound will come out of the internal speaker (no headphones or jacks connected). The system refuses to select the HDMI output in System Preferences.


I find that restarting the Mini with the AV reciever turned on seems make it output through the HDMI, but it is annoying to have to do this every time I want to just listen to music.
