In 16-bit linear PCM mode, this byte contains the upper eight bits of the left audio data sample. In the 8-bit companded and linear
modes, this byte contains the left audio data sample. In mono mode, only the left audio data is used. MSB first format is used in all
modes, and twos-complement coding is used in 16-bit linear PCM mode.

In 16-bit linear PCM mode, this byte contains the lower eight bits of the left audio data sample. In the 8-bit companded and linear
modes, this byte is ignored on input, zeroed on output. In mono mode, only the left audio data is used. MSB first format is used in
all modes, and twos-complement coding is used in 16-bit linear PCM mode.
