No Audio With Systemd Command Service on Raspberry Pi Raspberry by komal swami - September 26, 2024September 26, 20240 while working on integrating sound playback into a flask service on an RPI. I encountered this issue where No Audio With Systemd Command Service on Raspberry Pi. Th issue where sound would play when running the Python script manually but when running it as a systems systemd service. After troubleshooting, I managed to solve the issue by making adjustments to the system's service file and sound configuration. here's a step-by-step guide. The solution was into basics, as you know there is thin line between, process context switch, process state switch and process mode switch. Context switch occurs between two different process while process mode switch occurs between two modes of same process but in these two 'context' is saved. Process
