Thanks for your suggestion. I belive that I tried setting that target (and obvious variants) previously. To be sure, I tried again and the build failed. See error log below.

Thanks, Eric

I have been developing for the audiokit v2.2 as a variant of a lyrat for a while.

I picked up a esp32-s3-box-3b,and attempted to build the pipeline_passthru demo code after selecting the esp32-s3-box HAL. The compile failed (see error msgs below). How can I properly configure for this board ...

My app needs to implement a dsp between a microphone input and a speaker output. A year ago, we sucessfully implemented it using esp-adf and the audiokit v 2.2 board. This board, which is very similar to the lyrat v4.3, uses a single codec for both microphone and speaker, and the board_config ...

esp-adf only has a board config for the mini v1.1 board. Turns out it works for v1.2 too. However, the passthrough app doesn't work because this board has different codecs (on differnet i2s ports) for input & ouput. (weird)

I changed the stream configs in passthru and it now works:

i2s_stream_cfg ...

I purchased a lyrat MINI v1.2 and now realize that esp-adf only includes a borard config for v1.1. The pipeline_passthru example app doesn't seem to work, so I assume that the codec configuration differs between those boards.

Espressif's site doesn't seem to publish any info on the 1.1 version, so ...

I notice the following problematic copyright notice on nullpipe.*. What restrictions do they impose on products that use code derived from it?
