I tried to force audio to audio jack with
amixer cset numid=3 1 or using the
raspi-config which works for other applications like audacity, vlc and other multimedia software except for the alarm clock
alarm-clock-applet https://github.com/joh/alarm-clock , Which I am using for a project. I tried removing pulseaudio to avoid conflict but yet no success.
The alarm clock plays audio only via HDMI. I am using the new Raspian Buster. The Alarm Clock do not work properly on previous Raspbian.
I need help to get audio out via USB Audio PnP Sound Device or default audio jack. If it will be possible to modify the settings of the App which I am still trying to find out how.
