ESP8266Audio & TTGO LoRa #574

Hello,

I'm using this library to play a mp3 (from SPIFFS) and a Lora to communicate with another unit. Basically mp3 is played when a msg has been received. I use TTGO ESP32 Lora board with a small speaker and MAX98357 amplifier in between. Now I have noticed, that the LoRa reception is much better when the line that triggers the playback of the mp3 is simply commented out. With mp3 working I get RSSI of about -96 and without mp3 it's around -120. Has anyone else experienced anything similar and could explain what's the problem? I've tried with WAV format too but it was the same. After a reboot, the first message is still ok, but once an mp3 has been played it seems that the signal is not that good any more.

Thanks a lot in advance.

Regards
