[solved] sound on audio jack instead of hdmi

[Nachteule]

You don't have do install anything.

I had the same problem with my 64bit test installation that I'm currently developing when I checked it.

Strangely enough I don't have the problem with my standard installation, although it is also 64bit and has the same kernel and firmware.

I found out that the firmware somehow has an error when processing the /boot/config.txt and therefore
dtparam=audio=on
is not processed correctly.

Remedy is to add a

dtoverlay=

before this parameter, then it works

I've added that dummy parameter as follows:

Code:

# ******************************************************************************
# * Various settings see also: https://elinux.org/RPi_config.txt               *
# * to obtain keys visit the shop at https://codecs.raspberrypi.com/           *
# ******************************************************************************

[all]
dtoverlay=

# Enables turbo mode from boot for the given value in seconds (up to 60) or
# until cpufreq sets a frequency. Default 0
