Hi, I've looked at the reported problem of aRts crashing when Noatun is
started, and I believe I know what happens. On my box running Cooker and KDE
CVS HEAD, the crash is apparently caused by the inline asm SSE volume code in
kdemultimedia/noatun/library/noatunarts/StereoVolumeControl_impl.cpp
Since I don't know enough about inline asm to fix it myself, and I don't know
whether the author will get a chance to look at it anytime soon, I think the
best solution may be to disable that SSE code in MDK packages for now, since
minor performance degradation is nowhere near as bad as the whole app not
working. This is what the attached patch (which has been reviewed by Noatun's
maintainer) does. It certainly works for me, but since I am not running MDK
packages, it may be a good idea for someone who has the crashing problem
using them to to aply this to the kdemultimedia packages, and test it out..
Thanks,
Maks Orlovich
