Step 2: Make sure your computer can output audio to hdmi I think hdmi sinks will have a description of the form "blah High Definition Audio Controller" while non-hdmi sinks might have a description like "blah blah blah Speaker + Headphone". If you are not sure if it does or not, you can also run pactl list sinks | grep description for more human-readable descriptions of the devices detected. If your hdmi audio does not show up in your list, then we may have found the problem, so keep reading. This should produce a list of things of the form 0 alsa_output.pci-0000_06_00.6.HiFi_hw_Generic_sink module-alsa-card.c s16le 2ch 48000HzIDLE You can list all sinks loaded into PulseAudio with pactl list short sinks. Step 1: Make sure PulseAudio hasn't detected your hdmi sink It seems PulseAudio has a bug which can cause it to fail to automatically detect hdmi audio outputs ("sinks" in its language), so you can fix things by manually telling it about your hdmi device. This is mostly taken from the suggestion here, but slightly expanded/modified. But in case you have not or in case others are running into this issue and not finding solutions which work for them (as was the case with me recently), here is another thing one can try.
This is an old question, so maybe you have already solved your problem. In the Settings -> Sound -> Output -> Output Device I have just two options to choose from:Īnd in both of them all the options with HDMI are displayed with (unplugged)(unavailable).įinally, the sound just works in my laptop, if I connect HDMI cable it display correctly but the sound keeps on my laptop. When I run aplay -l I have these results: HDMI worked perfectly when I used Windows 10 before replacing it with Ubuntu. Ubuntu 18.04: Audio doesn't work unless I switch between outputsĪlso I've downloaded Ubuntu 20.04 iso again and reinstalled the system, but it doesn't work. HDMI sound not working after upgrading to 20.04 Some of the solutions I tried are located in the following links: I tried lots of solutions here on Ask Ubuntu, but the problem remains. The display on HDMI works just perfectly, but the audio is not working at all. Overall the system is working fine, but I'm having a big issue with HDMI Audio.
I just installed Ubuntu 20.04 on my laptop which is a bit outdated:
