No audio on HDMI

Former Member
Former Member over 11 years ago

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.

    The only thing that I can think of is that the 'pi brings up the video and the audio part of the HDMI signal in two stages. If by the time the 'pi brings up the audio the TV has decided to stop listening.....

     

    Anyway, that would mean that if you manually change over to TV (anything not HDMI2)  and back to HDMI2, it would work. Does it?
