[parisc-linux] CD-ROM Audio Output

[Rüdiger Scholz]

Hi there!

I want to install a CD-Drive in my 715/100. Is it possible to use the 
internal audio output of the CD-ROM in the same way it used in a PC? 
Which type of cable do I have to use?

TIA, Rüdiger

The problem is where to connect it. There's no way to plug it in to the
built-in audio. One alternative might be to use an EISA or ISA soundcard
that has the right connector for a cdrom cable, but I'm not sure if
anyone's tried that yet. If anyone does, please post notes to the list.

If you want to listen to audio cd's you could just plug directly into the
cdrom output and then control the drive via scsi. That's what I used to
do with hpux and I don't see any reason why it shouldn't work. But then
you don't get the mixing with other sources that the sound card provides.

That's bad. Cause my my 715 has no EISA/ISA-Slot. When I opened the 
machine, I recognized a 3-Pin-Connector (labeled J19) near the hinges 
and the power connector. So I thought this could be an audio connector...
Well, so let's do it the other way...

By the way: is it possible to get some documentation for my machine?

The 715 should have a expansion board with an EISA connector.

You can find the service doc at:

Many of the 715s were sold without the EISA expansion board.

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.

I stand corrected. Do you know if systems ever shipped with the CDROM 
connected to that input?

Really? And the pinout is? rggl?

I'd still like to know if there's a manual (the more complete the better
;) for the 715. It seems to be very hard to find even uch information on
these but any manuals or such material seem to have gone in the same
direction as old Alpha manuals.
