I'm having problems getting sound to work on my RPi. I'm running raspbian, and I want the sound to play over HDMI.

I've tried omxplayer -o hdmi path/to/myfile.mp3 with the HDMI cable, and omxplayer path/to/myfile.mp3 over analogue. None of them works.

The system is updated and upgraded to the latest packages, I've also done modprobe snd_bcm2835 which as I understand enables audio?

Is sound supposed to work out of the box or do I have to get any packages or something?

  • Try running amixer cset numid=3 2, which should force audio be go through HDMI. – Gerben Nov 8 '13 at 20:35

audio via HDMI should work out-of-the-box, however there are some issues with your HDMI receiver (e.g. TV which raspberry pi is connected to)

see my struggle on this topic here: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=28&t=57984&p=442479#p442479

gerenally check if hdmi_drive=2 or even better set hdmi to safe mode

    I edited /boot/config.txt and uncommented both hdmi_drive=2 and hdmi_safe=1 but still no sound. – justanotherhobbyist Nov 8 '13 at 16:57
