The Sxx_xE format describes how the samples are formatted in memory, i.e., how the DMA controller expects to read them. > S24_LE in wav file .wav files do no use ALSA sample formats. Please describe the values of the header fields in this .wav file. > Question: is all HDMI support 24 bit must have 32bit support? That depends on the DMA controller. Most use 32-bit alignment for 24-bit samples.
