PSRAM causing audio interference

PSRAM викликає аудіовзаємодії

https://ift.tt/9uZoskm

Chip type: ESP32-S3 (QFN56) (revision v0.2)
Features: Wi-Fi, BT 5 (LE), Dual Core + LP Core, 240MHz, Embedded PSRAM 8MB (AP_3v3)
Crystal frequency: 40MHz
Manufacturer: 68
Device: 4018
Detected flash size: 16MB
Flash type set in eFuse: quad (4 data lines)
Flash voltage set by eFuse: 3.3V

У yaml-конфігурації нижче аудіо мікрофона містить багато попухів та тріскоту і шипіння. Однак, якщо я закоментую або psram, або CONFIG_SPIRAM_FETCH_INSTRUCTIONS, то аудіо стає бездоганно чистим.

Я хотів би зрозуміти, чому так відбувається. Є у когось ідеї?
