No audio on HDMI

Former Member

I have a Raspberry Pi B connected to a TV through one of the HDMI ports using an HDMI cable. The TV is new and the HDMI cable came with the RPi kit. The video is great and all the software works fine. The only problem I have is no audio over the HDMI. One indicator that my be relevant is that as soon as the RPi starts up the TV display switches from “HDMI2” (for HDMI  port 2) to “DVI2”. I think it is seeing a DVI input instead of HDMI. I tried an HDMI port on a computer to the TV and it stayed “HDMI2”. I tried the DevKitsFast.mp4 from  the Element14 training videos and it worked fine when started from the command line as: omxplayer –o hdmi DevKitsFast.mp4, except again no audio. The same file worked great when I entered: omxplayer –o local DevKitsFast.mp4, and plugged some headphones into the RPi. I got video on the TV and audio out the RPi. I also noticed I have no reference to any audio or sound control accessories on my desktop (or anywhere else for that matter). I boot with a NOOBs card that came with the kit. Do I need to download other software for sound control? I did do an update shortly after I got the kit but no help.

 

Any help would be appreciated.

    Thanks for the help Ethan. I’ll see if this will help with my lack of audio with Scratch and the Python Games. My biggest problem now is a lack of time and my lack of Linux experience. Years ago I had to use Unix on a limited basis to test networks connected to Dec computers. I was encouraged to learn more Unix, but I didn’t. That was a big mistake. But now at least I can enjoy learning Linux. It seems to be more fun when it’s just a hobby.
