That is incorrect. Most, if not all parisc workstations with CD quality
audio have an internal connector for CD audio input. However, it is just
another buffered input to the line input, i.e. you can not separately
control the CD audio level and the line input level, since they are
essentially wired together to the same input on the CS4216 codec. The
exception is the newer workstations that use the AD1819 codec. That has
a separate CD audio input, and the CD input connector is wired to that,
rather than the line input. Of course, we don't have a driver for the
AD1819 yet.

The connector that was described in this discussion with regard to the 715
is indeed the CD audio input.
