Testing Output

I am using ffmpeg to test the functionality:

In order to prevent the following error: /tmp/snapfifo: Permission denied, I executed the following command

sudo sysctl fs.protected_fifos=0

And then I can start to play audio e.g. from a url with

ffmpeg -i http://stream.srg-ssr.ch/m/rsj/mp3_128 -f s16le -c:a pcm_s16le  /tmp/snapfifo

Stop the local snapclient

service snapclient stop

Edit snapserver

sudo nano /etc/snapserver.conf

I recommend to use Opus

# Default sample format
sampleformat = 48000:16:2

# Default transport codec
# (flac|ogg|opus|pcm)[:options]
# Type codec:? to get codec specific options
codec = opus

In the file SnapConfig.h in the Arduino Library Directory define your values for CONFIG_SNTP_SERVER CONFIG_WIFI_SSID CONFIG_WIFI_PASSWORD If you use PlatformIO you can provide this a parameter

Make sure that the ESP32 Core Debug Level is set to Warning or Error (in Arduino this is in the Tools menu)
