Why does HDMI audio output only play test tones?

by bcrose_pt / May 20, 2012 6:20 AM PDT

So I have been trying all day to get my sound to play through the HDMI ports (fiddling with settings, searching forums, etc.) Funny thing is that the only sound that comes out are the test tones. I tried going through general computer-wide settings and into the individual players themselves (VLC media player and iTunes) to see if I needed to change the output settings. I'm running an HP G50 into a Samsung flat screen. It seems like this has to be a setting option fault, but I can't figure it out for the life of me. Has anybody else encountered this problem?

Thanks in advance

It could be that HDCP rule?
by R. Proffitt Forum moderator / May 20, 2012 6:35 AM PDT

There is a rule about HDCP (sorry but please google the acronyms that you don't know) where HD AUDIO is downgraded to STEREO when the host device can provide audio. This area is not consumer friendly and I will not tell you how to get around this. (See forum policy.)

Make sure the audio is stereo and it should make it over to the HDTV unless there are issues such as HDMI to DVI convertors etc.

There's also a setting in the control panel to look at. Here's a picture.

For that setup, my HDTV was that HP.

That's pretty normal (sadly!)

In reply to: Oops.

I had to cover the usual since many are unaware of that setting. On my laptop, no reboot was needed (it knows to OBEY me?)

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
