Hi,
I'm trying to deploy a colinux service with a specific distro. And
i've some problem with sound.
As it's write on the wiki as
http://colinux.wikia.com/wiki/Sound_support_in_Colinux, there are 3
means to have a sound support into colinux :
- ESD server on Windows and redirect sound into colinux with
ESPEAKER env var. In my system, all the sound is managed with arts. So
I configured arts to set ouput on ESD and in /etc/environnement, I
declared ESPEAKER=3Dip:port. After a reboot (or a env update), all my
sound system is redirect on my Windows, so I launched an ESD server
and i listened music and alert sound system. But I've too much
latency ! There is more than 2 seconds ...
- Icecast/shoutcast : this solution is more interessant cause the
stream is in OGG/MP3. So i tested : arts -> local esd server -> esdmon
to catch the esd sound | ices ------> icecast ----> windows ogg/mp3
player. Result : I've more and more lantecy : I've same latency cause
the esd redirect plus the icecast management which is not designed to
do Real Time transport.
- I don't wan't use the NX solution because NX utilisation is
difficult and there are not full open sources solution. But when i
tested, there was latency too. And this is not a surprise cause NX use
esd /arts redirection ...
So I explored all solution of the wiki and there are none usefull.
Is there anyone who has less latency than me ?
Others ways :
- VNCAudio : there is an old implementation project here :
http://linux-workshop.com/bybell/vnc/vncaudio.html. It's based of a
virtual sound card (oss driver) which allow to a vnc process to easily
catch the stream. I'm trying to use it.
- what's it's not possible to have native sound into colinux ? If we
can catch the stream, does the colinux process can see it and listen
into the windows ? (excuse this naive question, I've not any knowledge
about how colinux works...).
My last naive question : is it not possible to stream sound into a
pipe file placed in a cofs dir to allow to a Windows process to cactch
and listen it ?
thanks a lot, i apologize for my English ... (I'm french)
