• Manufacturer Part Number: alc888s
• Description: 7.1+2 Channel High Definition Audio Codec With Two Independent S/pdif-out
• Manufacturer: Realtek Semiconductor Corporation

Rates in multiples (n) of 44.1kHz applying this cadence contain n sample blocks in the non-empty frame
AND interleave an empty frame between non-empty frames (Table 9, page 19).
