Oh no, after playing around a bit more (and switching to raw PCM streaming for testing) I realized that the real problem is in my application (decoder task).
After fixing this, the ESP32-C6 happily decodes OPUS 48kHz with ~60% time consumption in the RTOS and thus a very happy TWDT :geek:

Re: ESP32-C6 low-latency audio decoding
The "Low Complexity Communication Codec" (LC3) may be what you need: You can chose from 2.5 ("LC3plus")/7.5 to 10ms frame duration and it is designed to be computationally "low" complexity.
Interesting idea! I have now tried LC3 in my setup on ESP32-C6. Unfortunately, I encounter similar ...

ESP32-C6 low-latency audio decoding
Hello
I'm trying to stream encoded audio to a ESP32-C6, decode it and play it back via I2S.
Currently, I use the OPUS codec in https://github.com/espressif/esp-adf-libs/tree/master/esp_audio_codec for decoding.
Parameters are Stereo, 48kHz and 5ms samples. The samples are encoded on a x86 machine ...

ESP32-C6 chip antenna hardware design OA-C07
Hello
I'm trying to use a OA-C07 chip antenna in conjunction with a ESP32-C6FH4 chip.
This is my current design. The design is based on the matching network described in the antenna datasheet page 4 https://fcc.report/FCC-ID/2ajyu8xn0001/6207412.pdf

ESP32-C6 Serial/JTAG Controller
Hello
Is it possible to change parameters like the string on how it advertises itself over USB?
I remember other boards advertising with specific strings, but not sure if this is just possible for C3/S3.

Re: Faster DHCP IP
Thanks for reply. Ok, do you have any idea on how to do the DHCP caching in RTC memory? I have no idea on how to basically set an static IP on the ESP32 with the esp-idf

ESP32 JTAG Debugging
Hello
I'm currently trying to get my ESP32 WROOM on the Devkit connected with an FT2232H FTDI Adapter. I hooked up the 4 JTAG Lines. No Reset. When I try to flash the binary via JTAG I get the following Error. Is this a common fault?
I already tried lowering the Speed from 20M to 5M.

ESP32 WROVER pSRAM Quiescent current
Hello
I'm just asking if and how big the difference of the quiescent current between the ESP32 WROVER and ESP32 WROOM Module should be in deep sleep mode.
Thanks
