The emerging standard, and one that LTSP will support, is the gstreamer audio and multimedia framework. Anything that writes to ANY /dev/dsp in this day and age is broken, broken, broken, broken, broken. The early 1990's called, and asked if you could send it's device interface back. These days, NO end user app should be opening anything in /dev: there's toolkits for everything. If you want an app to do sound properly, then have it do gstreamer, and be an audio source/sink. These we'll be able to route around the network transparently. Solutions like Pulse Audio and MAS allow for proper, transparent network sound, that will work seamlessly. > details: > The server-machine runs a network daemon > The client-machine contacts the server-machine and connects soundcard, via > network, to server-machine. > The application, displaying on client-machine, running on server-machine uses > server-machine /dev/dspN to talk to client-machine /dev/dsp > > Problems are: > Managing the N part of /dev/dspN (what N does your skype use eg /dev/dsp37) > The network-server-driver implementation. > How it scales eg 10 clients? 255 clients? How are you going to send ioctls()? How are you going to send lag info? Sync frames? etc. These problems have already been solved in Pulse and MAS, and plug into gstreamer or phonon. > Maybe ... > A paradigsm shift to thick-clients.

By the time you finish buying one one of those, for another $70, you could add a hard drive. The TRICK's gonna be getting it all to work on a 32M or 64M pentium II 233. There's LOTS of those still out there. They should be terminals, and switching to a proper audio stack's the solution to that. Scott -- Scott L.
