No Sound with RPi 4

Hello,

I installed LibreElec version 9.2.0 on a Raspberry Pi 4 B 4Gb and I have no sound.

I connected the HDMI cable to the HDMI0 of the Raspberry, the sound output in the configuration is on HDMI and the sound does not come out on the TV

Do you have an idea?

Set audio output to HDMI and analogue. Then plugin headphones on your RPi to check whether you hear audio.

A second test is to disable audio pass-through at Settings -> System -> Audio.

Audio pass-through is disabled.

And when i set audio output to HDMI and analog, I have sound from the analog output.

I have another Raspberry connected to my TV (a RPi 3B+) and i have sound by HDMI port.

Does it affect all audio formats, even mp3?

Do you have all other audio settings on default values (especially amount of channels should be 2)?

All audio formats are affected.

Configuration of LibreElec is default for all parameters.

Even system sounds are affected.

Login by SSH, and open the settings file by nano /storage/.kodi/userdata/guisettings.xml.

My "audiooutput" part looks like this:

Code

<setting id="audiooutput.ac3passthrough" default="true">true</setting>
<setting id="audiooutput.ac3transcode" default="true">false</setting>
<setting id="audiooutput.atempothreshold" default="true">2</setting>
<setting id="audiooutput.audiodevice">PI:Both</setting>
<setting id="audiooutput.channels" default="true">1</setting>
<setting id="audiooutput.config" default="true">2</setting>
<setting id="audiooutput.dtshdpassthrough" default="true">false</setting>
<setting id="audiooutput.dtspassthrough" default="true">false</setting>
<setting id="audiooutput.eac3passthrough" default="true">false</setting>
<setting id="audiooutput.guisoundmode" default="true">1</setting>
<setting id="audiooutput.maintainoriginalvolume" default="true">true</setting>
<setting id="audiooutput.passthrough" default="true">false</setting>
<setting id="audiooutput.passthroughdevice">PI:HDMI</setting>
<setting id="audiooutput.plladjust" default="true">0</setting>
<setting id="audiooutput.processquality" default="true">30</setting>
<setting id="audiooutput.samplerate" default="true">48000</setting>
<setting id="audiooutput.stereoupmix" default="true">false</setting>
<setting id="audiooutput.streamnoise" default="true">true</setting>
<setting id="audiooutput.streamsilence" default="true">1</setting>
<setting id="audiooutput.truehdpassthrough" default="true">false</setting>
<setting id="audiooutput.volumesteps" default="true">20</setting>

Then go to the bottom of the file content and check that audio is not muted and has a noticeable volume:

Code

<audio>
    <mute>false</mute>
    <fvolumelevel>0.900000</fvolumelevel>
</audio>

Hi,

Sorry for delay.

Now, RPi4 don't boot...

I send it back for a refund.

Thank you for your help anyway.
