Sound distorted when VT100 is enabled #69

Hi, I discovered another Problem with the Esp32 Audio Kit V2.2 2957 ES8388 Board. When I #define VT100_ENABLED The sound playback is very distorted. Is this normal ? What do you select in the Arduino Ide 's Tools menu? I have the following settings there: Board: "ESP32 Dev Module" Upload Speed: "921600" CPU Frequency: "240MHz (Wifi/BT) Flash Frequency: "80MHz" Flash Mode: "QIO" Flash Size: "4MB (32Mb)" Partition Scheme: "Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS)" Core Debug Level: "Verbose" PSRAM: "ENABLED" Arduino Runs On: "Core 1" Events Run On: "Core 1" Port: "/dev/cu.usbserial-0001

Is this right? regards, paul

Hi Paul,

the distortion might be caused by the Core Debug Level "Verbose". The core will/might be busy with creating a lot of debug messages. The rest looks okay to me.

Best regards, Marcel

Hi, I set the Core Debug Level to "None" but the sound is still super distorted when the VT100 output is enabled.

Hi,

I can observe the same issue when using the ESP32 board library version 2.0.2. Using 1.0.6 shows no issues. I had a lot of issues moving to the newer version. It sounds like that the Serial output call blocks the audio for each "frame" / textblock. I will try using the latest (2.0.5).

Hi @baesek , do you still observe the issue?
