esp_device_uac limited to 16 bits samples ? Intention of extension ?

Postby jmf111 » Fri May 15, 2026 7:50 pm

Hello,

I'm working on a usb to i2s bridge based on esp32-P4, based on the esp_device_uac component. For this component, the samples bit depth seems fixed to 16 bits.
See tusb_config_uac.h : #define CFG_TUD_AUDIO_FUNC_1_FORMAT_1_RESOLUTION_TX 16

Would you know if there is an intention to extend capabilities of this component to 24 and/or 32 bits samples, with format possible to select by the host with several alt settings?

Best regards,
JMF
