Frequently Asked Questions

• The audio quality is very bad and the sound is stuttering. I could not reproduce this issue with the proposed settings, but you still have a lot of options:
  • Make sure that you set the log level to Warning or Error or you deactivate the logging.
  • Use the Opus codec.
  • Try to increase the I2S Buffer
  • On the Microcontrollers that support FreeRTOS you can use the ProcessorFreeRTOS which uses some additional buffer
• Do I need to define the Server IP address
  • The Server IP address is determined with the help of MDNS when you use an ESP32.
  • On other platforms you must define the server IP address either in the configuration file (CONFIG_SNAPCAST_SERVER_HOST) or on the sketch (setServerIP()).
  • Even on the ESP32, I recommend to define the server address, since MDNS might fail.
