RISC OS Open: Forum: Mozart Sound Card with Risc OS 5.

May 5, 2015 12:59am

Hi all,

Just in the process of upgrading a Risc PC from Risc OS 3.60 to Risc OS 5.22. This one has a ‘Mozart 16 bit sound upgrade’ card plugged into the motherboard. I remember reading users suddenly having trouble with their sound when they upgraded to Risc OS 4, while keeping this card. So, my question is whether i would be best to take it out or will it be ok to leave it in?

With regards to the motherboard, I don’t know which issue it is nor how to tell but I have got another Risc PC (unfortunately, needs repairing at the moment) which says ‘1208,000’ which signifies that it is Mark 3 – and this one is definitely different to that one.

Also if anyone can recommend repairs for my

Any support software will probably be non-32 bit – you could try dropping it onto Armalyser to show up obvious problems.

Isn’t a Mozart Sound Card not like an Acorn ACD05 Risc PC 16bit sound upgrade but sound mixing facilities added? Then the digital 16-bit linear audio part should work without support software.

I had a Mozart card in my RISC PC a few years ago, it just worked with RISC OS 4 and RISC OS 4.39. No modules or support software needed adding. It should be fine with RISC OS 5.

Mozart card works fine here with RO 4.39 as Lee says.

I’m sure 5.22 is compatible with Mk 1 & 2 motherboards as well as Mk 3 motherboards which effectively have the 16bit sound Mozart card integrated on to the motherboard. So I’m sure when configured correctly 5.22 will work on Mk1 or Mk with a Mozart card.
