i think this is the AC97 codec. 9806 is just the manufacturing date
(same as the 9819 in the above one). on the intel web pages there is a
description of AC97 codec -- then manufacturers implement it with
different numbers etc but the packaging and external interface is the same
for all.

either a preamp or an amplifier.

If you think about it 4 digits (or 5, or 6) cannot possibly identify
each and every chip on earth, so before looking them you need at
least to know the manufacturer and the category of the device.
