RiscPC 700 Sound?

Post by Adam Wild » Thu, 24 Jun 2004 17:38:57


Hi all,

Does a RiscPC 700 have 16bit sound?

My dad now doesn't have enough room at his work to keep his RiscPC as he
doesn't really use it that much anymore. So he brought it home and I was
told I could use any parts to make our home RiscPC the best spec out of
the two, as both RiscPC's where similar specs so only a few things have
changed.

So I took out our RISC OS 4 roms from our RiscPC 600, put them on the
700 motherboard and put the RISC OS 3.7 roms on the 600. So now we have
two RiscPC's with the following spec;

RiscPC 700
SA 233
64MB+64MB+2MB
RiscTV
Network card
SCSI Card + Canon IX-4015
100Mhz 486PC Card (never used anymore as we both have high spec laptops)
15GB HardDrive
52xCD-ROM Drive
Cerilica Multimedia keyboard
Older PSU (I'm keeping this one as its very quiet)
Speakers for RiscTV
Speakers for machine (MP3s etc)

RiscPC 600
SA 200
16MB+16MB+1MB
16bit Mozart card
100Mhz 486PC Card (never used anymore as we both have high spec laptops)
10GB Harddrive
2xCD-ROM Drive
New PSU bought from Castle less than a year ago (230volts or 115Volts)

I changed the motherboards over as the RiscPC 700 is the newer one out
of the two and I thought it had built in 16bit sound. Whenever I play an
MP3, the sound is really bad, it sound as if the speaker has gone. Also
it the same if I play a CD and the speakers are fine.

Any ideas what it could be?

Also, how much would the second RiscPC be worth?
As we are going to sell it soon.

Thanks to all who reply.

RiscPC 700 Sound?

In article < XXXX@XXXXX.COM >,



With one possible exception. Early RISC PC m/b's (such as were used for
the first RPC's released) were 8-bit only but could be upgraded using an
add-on board (e.g. the Minnie board). RPC700's usually had the later
boards with the 16-bit sound capability added, but that isn't guaranteed.
To know for sure, you should check the issue of the board.

As far as your MP3 playback problems go, you might want to check that the
system is running with 16-bit sound enabled. If you issue a "*status"
command, then look near the bottom of the list for "SoundSystem" and see
what it says. If is doesn't say 16bit Oversampled, then use the command

*Configure SoundSystem 16bit Oversampled

If that doesn't work, it could indicate that the m/b is not as new as you
thought, or that something else is shot.

Yeah I've got the 16-bit sound enabled.

OK, then you need to check what you have connected to the sound system.
You may also have problems with the system itself, but check everything
first (it's easier than ripping the m/b out to replace it, which might be
the ultimate solution if everything else is proven to be OK).

You may also want to check whatever it is that you are using to play MP3's
with, e.g. is it up to date, is it correctly installed and configured and
so forth.

I found if I removed the RiscTV card the sound is fine.
Put the card back in and only connected the keying cable, sound is fine.
Connected the 16bit audio cable from the card to the motherboard and the
sound is bad again. I tried the cable around the other way (the opposite
way it was in the RiscPC 600) and the sound is fine. Also when I play
music now the audio comes out of the speakers directly connected to the
tv card. When you watch a channel the music is muted and you can then
hear the tv audio. This never happened on the RiscPC 600.

Thanks for your help Chika.

Only RPC600's were 8 bit, all RPC700's were 16bit.

At manufacture, yes. The trouble is, this far down the road, that you can
never be sure if a machine has been repaired with older boards, so I tend
to be careful about that, though if an RPC700 has been repaired using an
8-bit RPC600 m/b, you would think that whoever did it would at least put
an upgraded board in place! Strictly speaking, however, 8-bit sound boards
aren't likely to be that common, but you can never be too careful.
