HDMI, picture but no sound
 

Hi
I have recently built a small form PC. Cabinet is Cooler Master Elite 130 with an AMD Ryzen 5 2400g (the g is for graphics) on a ROG B450-i mobo. Using Ubuntu MATE 16 which installed without any problems . When I connected the HDMI cable to the mobo and then my TV there was a pcture but no sound. No sound from headphones too.
Thanks in advance.

A simple search like this: linux how to get sound through HDMI will turn up many How To's.

This one : https://www.fosslinux.com/455/fix-no...-os-ubuntu.htm

has oictures and words to assist.

There should be an application to control where the sounds go. It might already be in your system tray or it might be called something like "pavucontrol".

That should allow you to send your audio to the HDMI connection.

And to add what's here (the pavucontrol is good advice..since you get NO sound, things could just be muted...), are you positive that the HDMI device itself supports audio? Some don't.

The manual I could find for that motherboard says it does video, but doesn't mention audio.

I have an HDMI cable that has an attached sound cable with miniplugs at each end.

so it's not an HDMI issue?

What does the output ofreveal?

Hi can you post a photo or where you got it from? Thanks

HI. I was mistaken. The front headphone jack is not working, but the rear is fine.

Hi. The result of inix-axx is below.

CPU~Octa core AMD Ryzen 5 2400G with Radeon Vega Graphics (-MCP-) speed/max~1600/3600 MHz Kernel~4.4.0-150-generic x86_64 Up~36 min Mem~684.7/15031.0MB HDD~240.1GB(9.2% used) Procs~215 Client~Shell inxi~2.2.35
Also when I use Pavacontrol is says that the HDMI is unplugged.

That was an uppercase A in - it should show all your audio info.
My PC shows (for example)

Hi. I tried again and these are the results:

Thanks

Not trying to be awkward but did you plug the front audio into the motherboard?

HI. Yes, I dd, but thanks for asking. Sometimes the little things get forgotten. I even removed it and connected again.

this stuff needs to go in CODE tags, please remember to do so in the future!

there's 2 sound cards in there.
Maybe it's just a question of choosing the right one?
which brings us back to post #3.
