[linuxdc-dev]New pre-release version of Dreamcast AICA sound driver (dsp and mixer) available for testing

[Adrian M. <ad...@mc...>]

A new, much improved, pre-release version of the open sound system (OSS) 
compatible AICA sounddriver for Linux on the Dreamcast is available for 
testing.

This version implements a new buffering mechanism that has meant continuous 
playing of PCM and MP3 samples. The driver needs to be tested in very high 
demand environments (eg MPEG video) as there is potential for synchronisation 
problems - I haven't ported any such applications, but I know others have and 
could test this.

Anyway:

The files are at:

http://www.mcmen.demon.co.uk/linuxdc/aica

You need aica.c and arm7.h to build the drivers

However, as this is an OSS driver you will also need a minimal OSS system on 
your DC. The files and a smaple makefile are also available at the above 
address to build this. Simply download, alter to fit your set up and install 
with insmod soundcore.o and insmod aica.o


Please feel free to post any questions to me or (preferably) the linuxdc-dev 
(and others if you feel it appropriate - but don't spam people) list.


Happy New Year to all,

Adrian
