Garbled sound on ESP32-S3 and ESP32-P4 with USB UAC

[digitalLumberjack]

Hello :)
I'm trying to use an ESP32-S3 as an USB audio card for a PC.

Host -> USB -> EPS32-S3 -> i2s DAC -> speaker

I'm using the vanilla examples from https://github.com/espressif/esp-iot-solution/tree/140c954582243c73a276d224db4a632591484201/examples/usb/device/usb_uac

I tried with :

• ESP32-S3 custom board and the ESP32-P4 Ev Board ( so two different dacs)
• TinyUSB 0.17.0, 0.18.0

Everything seems to be working well, until the sound get garbled for 2 to 10 secondes every 1/2 minutes playing.

I already opened an issue on espressif/esp-iot-solution#525 where i logged all my tests, but I'm running out of idea, maybe I'll find new leads with your help.

Thank you very much for reading me :)
