Is it possible to enable "philips" mode (data one clock shifted) for PCM Bluetooth HFP Audio Gate example?

Hi, sorry to reply you so late. Maybe the "philips" mode you mentioned is one of the three modes of I2S in the esp32 document. The default PCM output waveform of hfp_ag example is similar to the MSB Alignment Standard in the document and currently cannot be changed to the philips mode.
