Problems with the output of audio

Hello,I have created a new dietpi system.

An RPi 4B 8Gb was used for the system, with dietpi running on an SSD. Furthermore I installed a RTC, a “Geekworm” part (X825-C8), the interface X825 V2.0 and the power management board X735 V3.0. It works fine, I installed Xfce and a 10.1 inch monitor.

Unfortunately I can’t get the audio output from the RPi to work.

The audio output is to be done via the audio output of the RPi is connected to the monitor.
When calling the mixer I get the following error message:
Execution of the command >>pavucontrol << failed.

Failed to execute child process “pavucontrol” (file or directory not found).

I claim to have set up everything correctly otherwise.

A post-installation of pavucontrol with sudo apt install pavucontrol has also brought nothing, except that no more error message comes, but a mask from the Mivxer appears. It says, “Connecting to PulseAudio. Please wait…”.

But then nothing happens anymore.

Another post-installation of pulseaudio did not help either.

Any tip is welcome.

Best regards,

Carsten

So you want to output audio via HDMI?
I think by default all audio output is disbled. Did you already enable it? If not:

When enabling in dietpi-configAudio options, some packages are installed, like ALSA etc. After the installation you can choose the soundcard which should be used, if you want audio via HDMI it is the 3rd entry rpi-bcm2835-hdmi.

No, I don’t want to use HDMI audio, I don’t think the monitor can. I want to use 3.5mm audio instead, I have that selected anyway, but it doesn’t work.

The problem was solved in an unconventional way by using a USB DAC.
