I don't think so. I think that the Suse RPMs are ok.

I agree with you, it is why there is a sound that is played on incoming
calls... Btw Im not sure sawfish is using the Gnome subsystem to play
sounds. You should try under gnome, and see if it works or not.

That is what happens if you are using ESD...
I think it is technically hard to add support for both ESD and ARTSD at
the same time in PWLIB. The solution would be to support one or another.
But if I support ESD only, KDE users will complain, and if I support
artsd, Gnome users will complain. So my current policy is to wait for a
common sound daemon for both desktop environnments and to not support
any of them. Moreover, supporting such daemons can introduce latency,
and as I told you, ESD, for example, only support one device at a time.

You could also code me the functions that shut down artsd and reenable
it. That way I could do like for ESD (the behavior that you describe).
I don't have artsd myself, so if you could code that (probably only 3 or
4 lines of code), I would be very happy. The trick is to suspend the
sound daemon only during calls and to reenable it after the call. Im
doing it for ESD, provide me the code for artsd, and it will be the
behavior for artsd too.

no, it should always work. Except if ESD is not working.
But I really think there was a bug in Gnome 1.x regarding that. I had
the same problem (sound not played) for GnomeICU too at some stage.

Yes. What happens is that ESD is suspended during calls, but as soon as
the call ends, ESD is reenabled.

Now if you want to tweak things, and only want to use one soundcard, you
can also compile PWLib with ESD support, and in that case, all ESD
programs will continue to work during calls. Last time I tried, it
didn't work well but I think it was fixed.

The only problem with this approach is that if you have a webcam
microhphone, it is unusable.
