Pi 4 B HDMI Sound issues

Tue Jul 02, 2019 8:21 am

Hi Team,

I'm a relatively new Pi user, so please be gentle!

I've bought a Pi 4 B, 2Gb for use as a media hub. Installed Raspbian and LibreElec from the NOOBS card.
It is connected to Sharp TV 1080p via HDMI cable

I'm having problems mainly with sound through the HDMI.
At first I was getting no sound at all.

I set hdmi_drive=2
This made the sound work in Rasbian, but not in LibreElec.
It also really effected the screen size in Raspian. I can probably sort the screensize with a mix of Pi and TV settings, but really odd that this would change it so much.

I've tried different HDMI cables.
I've tried passthrough on/off
hdmi_group=1
hdmi_mode=16
hdmi_force_edid_audio=1
dtparam=audio=on

I've gone through every setting I can find in LibreElec (including disabling CeC), and as many online solutions as I can find, but I'm pretty stumped on this one.
All other devises can play sound through the HDMI port to that TV fine.

Any help would be appreciated.

Subscribed, same problem.

I have tested on an ultrawide monitor (2560 × 1080) and the audio and video output works, but on TV (1920x1080) the audio output does not work

I've tried the same things as you, I'll keep trying

I'll hopefully get a chance to look at this in the nr future.

See https://www.raspberrypi.org/forums/view ... 4#p1526690 for discussion of audio from both HDMI ports independently.
