Copy fix for ESP32-C3-Lyra-V2 from SPIFFS sample (AUD-6638)

[dragonx]

Description

Sound output on the ESP32-C3-Lyra sounds terrible in this sample, while it seems to work fine in the pipeline_spiffs_mp3. Copy fix from that sample.

Testing

Verified on an ESP32-C3-Lyra V2 board. Music sounds much better.
