LPE_STREAM_B_PAUSE_RESUME:
DMA pause fetching at the boundary of buffers
when this bit is set, and resume fetching when this bit is cleared.
1- DMA stop requesting more audio sample from buffer A,B,C,D after reading and
depleting all data from current buffer
0- DMA resume requesting data from the next available buffer (A,B,C,D).
Programming note: this bit should not be used by SW driver. When SW driver wants to
pause audio, it shall invalidate the two newest allocated audio buffers. When the current
audio buffers are processed, silent stream is sent automatically.

LPE_HDMI_DP_MODE_ON_STREAM_B:
1= DP mode
0 = HDMI mode (default)

BOGUS_SAMPLE_DISABLE_FOR_ODD_CHANNEL:
When number of channels in a
sample is odd (3, 5, or 7) source application may pad a bogus sample to the next even
number of channels. If this bit is set there is no padding in input buffer1= No bogus
sample present in buffer for odd number of channels
0= Bogus sample present in buffer for odd number of channels (default)

LEFT_ALIGNMENT:
When input buffer is in 32-bit container mode. If this bit is set the
MSB of audio sample is aligned bit 31 of the container if this bit is clear MSB of audio
sample is aligned with bit 23 of the container.1= MSB is bit 31 of 32-bit container
0= MSB is bit 23 of 32-bit container (default)

_16_BIT_CONTAINER:
When this bit is set 16-bit sample is stored in 16-bit container
format. When it is clear container is 32-bit for each sample regardless of valid bits
(default)1= 16-bit container
0= 32-bit container
