Q: hdmi sound problem began after 10.7.2 update

same here no audio after update for my Mac Mini to 10.7.2 neither via HDMI nor headphone jack

I can confirm the same behaviour, however I am able to route audio to the HDMI interface using an application which allows you to specify the audio destination (Airfoil Speakers).

I'll log this issue with Apple and let you know if I get a resolution.

Same thing here: after 10.7.2, I`m unable to switch from Headphones to HDMI audio. I`m unable to use audio anymore !!!!

have you tried fooling around with Audio MIDI setup? hit cmd space, type audio midi hit enter, then try to see if changing your setting around will work. is this issue happening all the time or after playing a video with digital out?

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.

SmokeMonster,

I've not had any success in getting default audio route to the HDMI port via the Audio MIDI utility. The behaviour isn't changed before or after launching QuickTime or XMBC to play media files.

Unfortunately, I don't have any optical devices handy to verify behaviour when using digital output.

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.

I just double checked and I did have a wire (not connected to anything on the other end) plugged into the headphone jack. Once I removed the wire I was able to select the HDMI output device.

If I remember it correctly, Lion 10.7.1 fixed the HDMI audio issue (based on the update info), but how did it start to go faulty again?  Unless i unplug the audio jack, otherwise, the HDMI just will not work.

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?

As far as I know, 10.7.1 fixed the audio issue that was

the same in 10.6.8 where stereo output was disabled

whenever a Dolby or DTS audio was played.

Same problem here on my 2010 Mac Mini with 10.7.2. Extremely annoying. I hope we don't have to wait until 10.7.3 until this is fixed.
