HDMI Audio issue with Samsung Plasma

Hi all,

I have a mid 2010 Mac Mini that I bought for my HTPC. I am unable to get the HDMI audio to work after trying a number of connection possibilities. Here's the setup -

Mac Mini to Samsung via HDMI cable (1.3a) in either HDMI port - no audio
Mac Mini to Samsung via HDMI cable currently working for my uverse service - no audio
Mac Mini to Insignia LCD via HDMI cable in either HDMI port- no audio

I thought it was hardware, so I made a genius appointment and took it in. They gave me a new mini. Same exact issue.

When I switch to SAMSUNG in the sound properties, it tells me "The selected device has no output controls"

Video works fine.

What am I doing wrong? Did I just get two bad boards? This is really freaking annoying.

MacMini (mid-2010), Mac OS X (10.6.4)

I have a new Samsung LED 55" and I was able to get everything working perfect for about a month. Then, last week nothing. No display or sound.

I do recall having to go into the sound preferences and changing the output to hdmi or tv output. Then, if I waned my hulu tv to play via my hdmi I had to go into the hulu sound prefs and do it there too. It worked perfect. Now I just need to figure out how to get my hdmi signal to work again. I have another Philips plasma that it worked on before too, and that TV does work either. I tried two hdmi cables, nothing.

Any suggestions? Let me know if what I said above fixed your audio.

Kevin

The HDMI output on Mac Minis inherently does not support the volume controls in Mac OS itself. You either have to use the amp/TV's controls or those within the applications you're using themselves. As to your actual problem I unfortunately cannot help. You may want to look in either the sound options in Preferences or in the midi audio controls in the utilities folder in applications.

In my case that was no issue of the Mac Mini. In the Sound.app I had Samsung HDMI selected for output, but still did not have any sound from the speakers of the TV. Changing the settings for the TV fixed it. Here is what I did:
- open setup menu for the TV
- navigate to "input"
- select "edit name"
- select the "HDMI1/PC" jack
- select the name (strange term in this context) "PC"
et voila: Sound comes out of the TV speakers.

@Boyan11
This solved the problems with my UNC8000. Changing the name of the input to PC from PC-DVI did the trick. I walked through several of the options, and it appears that the name selection does more than merely change the name, in my Samsung TV at least. The video even switches and resyncs on a couple of them.

Thanks for posting this!

IIRC, older Macs don't put audio out the display port. http://support.apple.com/kb/HT4241 lists Macs that can push audio in addition to video out that port.


For an older Mac, you're stuck running a separate audio cable. Most TVs provide a conventional audio input jack next to one of their HDMI ports. You may then have to use the TV's remote control to configure that HDMI port to use audio from the separate audio input.


Sorry.

I have the same issue... perfect image on a Samsung TV UE32EH5300, but no sound. I tried changing the input name to HDMI/PC (and tried all others) with no success.


Altough I noticed one rare thing. I opened Mountain Lion AudioMidi Configuration and selected the HDMI output. Can't move the volume controls because these are supposed to be controlled on the TV. But when clicking at the Speaker configuration and making a test for L/R speakers... each TV speaker (connected by HDMI) reproduced statics.


THEN I'M CONFUSED!!!!... how can I hear sound produced by the computer but can't have the normal audio on HDMI???


Any help???
