Hi,
I’ve been successfully running Raspbmc for a couple of years on a Raspberry Pi 1 512MB. Today I upgraded to OSMC without changing any of my set up and I can’t get any sound through HDMI. Sound through the analogue port is fine.
I’m assuming these is either a config issue?
The receiver I’m using is a Onkyo TX-SR605. HDMI cable from the PI to the receiver, and then through that to the TV.
Please help 
Are you using the userdata folder from the old install?
Might be worth deleting that and setting up your settings again.
At the very least go to system/audio output in settings and “Reset above settings to default”, and then make sure the settings look right.
Yeah, it was a complete reinstall. I’ve tweaked the settings a lot, and then reset to default as well.
A direct HDMI connection from the PI to the TV produces sound, so it appears to be something between OSMC and my amp. This was all fine with raspbmc. Not sure what I need to do 
Have you tried out different settings in Audio Output? Fixed [44,48,etc], Best Match, Passthrough Enabled, etc.
Seems like your Pi may be outputting audio that your receiver doesn’t support.
Yep. Tried them all. Has OSMC changed that much from Raspbmc that it would stop working entirely? I’m not convinced this isn’t just a setting somewhere…
Is everything in OSMC Settings > Pi Config set to defaults? Not sure if the sound card overlays in there could cause any problems.
Yeah, it is.
Playing something with debug logs on would be great for us to look at.
Also: be sure to set audio for passthrough as well. You’ll need ‘Advanced’ or ‘Expert’ settings for this I believe.
Sam
Thanks Sam. Been away a couple of days, so only just had chance to do this. I enabled debug mode for the sound component. Started party mode, then hit next to start a new track and captured this:

No that is normal. Just shows that mp3 passthrough is not supported (as it doesn’t exist).
damn. Thought we might have something there. Any ideas on what to do next? I’m at a loss. I kinda don’t want to downgrade back to Raspbmc…
I’m giving up and attempting to roll back to Raspbmc but I can’t get the image to work. I’ve reformatted my SDcard, and written the image to it, but I don’t get anything from the PI to the TV via HDMI when I power it on. Am I missing a step? (No instructions with the image I can see)
If I install Noobs, that works fine (but as I don’t have a USB keyboard/mouse I’m stuck)
I’m getting fed up of nothing working
er…
Reinstalling OSMC from Noobs didn’t work… but changing the screen resolution from 1280 x 1024p to 1920 x 1080p did?
I now have sound…
confused
1280x1024 is a DMT (PC monitor) mode not a CEA (TV) mode.
Some TV’s (or AV receivers, if you connect via an AV receiver) will not accept sound in anything other than a CEA mode, even though the Pi is capable of sending sound in DMT modes.
You should stick to either 1280x720 or 1920x1080 as your output resolution if you want to guarantee getting sound on all HDMI devices.
You can check whether the current mode is CEA or DMT by running the following command via ssh:
tvservice -s
These two commands will list what CEA and DMT modes your HDMI device (TV or AV receiver) reports that it can accept:
tvservice -m CEA
tvservice -m DMT
What will it default to resolution wise on install? I don’t remember specifically setting it to that res (being as I have a full HD Tv, that would be a bit silly 
)

Hi,
Also had this problem and your solution didn’t help me but managed to get it working this way if anyone else has this issue.
Add these lines to /boot/config.txt and reboot Raspberry.
hdmi_force_hotplug=1
hdmi_drive=2
hdmi_force_hotplug=1 sets the Raspberry to use HDMI mode even if no HDMI monitor is detected. hdmi_drive=2 sets the Raspberry to normal HDMI mode (Sound will be sent if supported and enabled). Without this line, the Rasperry would switch to DVI (with no audio) mode by default.
Thanks to shinken in the runeaudio forum
