Hello, I installed 9.3 on my Compaq Presario laptop just a couple of days ago. I did a clean install because I had 9.2 and the upgrade was too picky about packages I had installed from apt-get. I have a couple of really esoteric questions which I think only gurus can answer. (1) Per Andreas Yaeger of SuSE, Firefox has been compiled as a 32-bit application (I installed the one that came on the SuSE 9.3 DVD). However, I observed that it can invoke 64-bit plugins (such as Acrobat and MPlayer) just fine! I even used 'strace' to make sure the plugins made calls to 64-bit libraries. How come, then, and a 32-bit Firefox can invoke 64-bit plugins, but a 64-bit plugin cannot invoke 32-bit plugins? (Currently, only a 64-bit konqueror can invoke 32-bit plugins.) (2) aRTS and artsdsp (both presumably 64-bit) seem to handle 64-bit programs fine. However, 32-bit programs like skype (www.skype.com --distributed as a 32-bit binary) and flash player seem to want to monopolize the sound card (skype is still not aRTS-compatible, even on 32-bit systems, but on a 32-bit system 'artsdsp skype' puts a"wrapper" around skype and routes its sound transactions through the aRTS sound server, so it shares the sound card). 64-bit programs seem to work fine in this respect, e.g. I can hear the sound output from my MPlayer (compiled from source as 64-bit) and amarok at the same time. My suspicion is that that artsdsp is 64-bits and cannot handle the 32-bit skype properly for some reason. (If I try to place a call via skype after amarok started playing, I get the error '/dsp/dsp-1: Device or resource busy' and if a fire up amarok after bringing up skype --even via 'artsdsp skype'-- amarok does not play until I shut down skype.) However, artsdsp does not send any error output to the terminal nor does it send any output to '/var/log/messages'. So, is there any way to make aRTS and artsdsp properly handle 32-bit programs? Is there any way to make 32-bit applications share the sound card with 64-bit applications?
