Open the file “/boot/userconfig.txt”:
sudo nano /boot/userconfig.txt
Add the following lines:
dtparam=spi=on
hdmi_drive=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
dtoverlay=ads7846
dtparam=cs=1
dtparam=penirq=25
dtparam=penirq_pull=2

“/boot/config.txt” and “/boot/userconfig.txt” look ok. In “/boot/userconfig.txt” there should be a line break after dtparam=ymax=3900. Although I don’t expect this to be causing the problem please try adding the mentioned line break to be on the safe side.
Apart from that the triple repetition of the last entries in both files appears strange to me. Do you have an idea what could have caused this?
To investigate further please post the results of
ls -al /dev/input
ls -al /usr/share/X11/xorg.conf.d
and
ls -al /etc/X11/xorg.conf.d
P.S. If possible don’t post images of the output of such commands but try to copy and paste the output as plain text and format it with code tags here. It’s easier read on mobile devices and can be searched through, too.
ls -al /dev/input

Looks normal.
Please execute
cat /dev/input/event*
and touch the screen. Do you see cryptic signs then in the terminal window?
You can exit the running “cat” command with Ctrl+c.
nothing happens
Hm, according to this in a thread that covers the same screen as yours nothing more should need to be adjusted than “/boot/userconfig.txt”.
BTW did you add the line break in “/boot/userconfig.txt” I mentioned above and reboot? If not, try that first. If touch still should not work maybe you need to install xserver-xorg-input-evdev
sudo apt-get install xserver-xorg-input-evdev
After that execute
sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
and reboot.
gvolt, thanks. Touch is working fine now. My son is enjoying Volumio in his toolshed

Have fun!
@bluswier Did you have to install “xserver-xorg-input-evdev”?
yes i did
Touch still is not working I assume. (?)
Are you referring to the line break in “/boot/userconfig.txt” or installing "xserver-xorg-input-evdev”?
Do you have any other hardware connected that possibly uses the Raspberry’s pin 22 (GPIO25)? This might interfere with the touch panel which also uses this pin to detect / signal touches (penirq=25).
no not unless innomaker dac uses the pin 22.
Doesn’t seem like that.
Is your display an original Waveshare or a clone?
