Hallo,

zeige mal die Ausgaben der Kommandos im Codeblock, das ist das -Symbol im schwarzen Balken.

cat ~/.asoundrc

cat /etc/os-release

head -1 /etc/rpi-issue

aplay /usr/share/sounds/alsa/Front_Center.wav

Bei mir mit 2019-09-26-raspbian-buster-lite.img sieht es so aus:

Code

pi@raspberrypi5:~ $ cat /etc/asound.conf

pi@raspberrypi5:~ $ cat ~/.asoundrc
cat: /home/pi/.asoundrc: No such file or directory
