Re: [LI] Glade Programming, Handling system event sounds.

[Nick Hill <nikhilwiz@xxxxxxxxx>]

Hi there! How are u trying to produce sound? Are u
writing to /dev/dsp directly? This is impossible when
the GNOME sound server is running, as it makes ESD ru
on /dev/dsp. ESD is a sound server. It has it own
client handling and security policies. U must first
request an authorisation from esd. I think u would
have to use IOCTL, or u can directly link to the ESD
lib, and use ESD routines to play u're sound. What ESD
actually does, is it kinda emulates sound mixing in
Software. So, less gifted ppl. owning even an ol' 8
bit sound card can play several sounds simultaenously.
The last time i check, i think ESD can mix 63 sounds
at once. I think that no. must have grown now. RTFM
for ESD or read the docs, which come with the source,
if u're a CVS kinda guy (like ME) ;-). hope this
helps.

Nikhil.
