Why does it default to Bluetooth instead of HDMI on first start? I had no step to configure the sound during the install process.

I installed a brand new RaspBerry pi 4B (8GB) with the latest version of the distribution. I was disappointed because on first start, LE decided to configure the sound goung thru the Bluetooth instead of HDMI. Don't know why but it took me some time to find the cause of "no sound" videos.

I wouldn't count on that "official" cable too much (source).

Your TV seems to be a new one, so it shouldn't be on the list of problematic old TV's (which need a workaround at config.txt).

I would buy another microHDMI cable (2.0 or 2.1 standard), and remove the workaround at config.txt.

The list of provided screen modes looks OK, I think the cable is just too slow to deliver them.

It's a brand-new Samsung .... I just ordered a new cable from Amazon ... expect to get it tomorrow if Covid-19 allows.

Are you using the HDMI port nearest to the power connector (good idea) or the other one (not such a good idea) ?

I used the right one (port nearest to the power connector)

Doesn't work. The cable is the original one (Official Raspberry Pi MicroHDMI Cable) sold by The Pi Hut.

How did you manage that? The RPi3 has a HDMI port, the RPi4 has a micro-HDMI port.

Perhaps your adapter cable is having a compatibility issue?

If it's working on a monitor having a HDMI port, I might suppose that the same cable can be used with a television.

Hello

I have just installed a new Raspberry PI 4 with the last LibreElec version 9.2.1 in order to move from my olg RaspBerry Pi 3B.

Everything was wroking fine with the previous hardware. When connecting the rpi4 on a monitor with HDMI port using the same cable, I get the image and the sound.

My environment:

• Raspberry pi 4 Model B Rev 1.1
• Television: Samsung QE55Q82RALXXN

I tried to find some answer using the search but what I found (see below) didn't change anything:

hdmi_enable_4kp60=1

Can someone point me to the right direction?
