The daemon is called esd, so if you had nothing named esd running then it is probably not that. This doesn't mean that it is not a problem with the way aviplay uses SDL though, when I do not have esd running aviplay just uses OSS sound output. You should see messages like: <aviplay> : Will try audio renderers in this order: OSS,SDL,noaudio if you run aviplay from an xterm. Even though you don't have esd running you could still have a similar sound daemon running, I think KDE uses one called arts (?) and so aviplay may use SDL for audio if the arts daemon is running. -- Adam [EMAIL PROTECTED] _______________________________________________ Avifile mailing list [EMAIL PROTECTED] http://prak.org/mailman/listinfo/avifile
