remote sound

remote sound

[Andrew Langdon-Davies]

Hello all,
The idea is to use an old p100 (there aren't any new ones) as an X 
client on which to display videos. The server is a Pentium IV running 
Mandrake 9.2. I am gradually getting there and so far can run totem or 
mplayer on the server and watch the results on the client. What I cannot 
get is sound. Both client and server have working sound. Both have 
esound installed. What more should I do to get the sound being produced 
on the server to be heard on the client?
TIA,
Andrew

I don't know the answer to this question, but I know where I'd look for
one.  I monitor a listserv called k12osn (it's a discussion by mostly
sysadmins about k12ltsp - a Linux terminal server project distro aimed at
running on computers in educational settings).  The issue of remote sound
comes up frequently, since the client terminals often need to have thier
own sound.  I think they have a Wiki, and maybe the question would be
ansered there.  Or else you'd probably find alot on the topic in the
archive.  Hope this helps.

I want to do the same thing.  This afternoon I'm going to try to implement 
the following idea:

1) on the client box where I plan to listen to the sound (music in my 
case), I'm going to listen for incoming tcp/ip connections using nc or 
the like and pipe the stream to /dev/dsp locally.

2) on the server box where the sound is to originate, I'm going to replace 
/dev/dsp with a local unix socket, open it using nc or the like, establish 
a tcp/ip connection to the client box and stream the data.

Does this sound like a stupid idea to anyone?

Sounds like its going to use a lot of bandwidth to me.  

Correct me if I am wrong, but isn't /dev/dsp for raw sound data AFTER
conversion FROM e.g. MP3 OGG WAV etc?  So "redirecting" /dev/dsp will
probably lag your network substantially.  I think this is a very cool
idea though, and you're probably on the right track.
