After piggyback a PSRAM glitches continues

Hi! I make this in my Lolin32 Lite and I got a "PSRAM found" (Hurrah!). image In a PSRAM test I got: image

But the dropouts continues, although they have decreased a little bit. In order for it to work, I had to change the upload to the settings below: image

Did I do something wrong?

On the ESP32, the PSRAM is connected via SPI, that's one reason why PSRAM is slower than SRAM. The ESP32-S3 has a quad and sometimes an octo SPI. Then the access times to the PSRAM are significantly faster and much better suited for audio applications.
