The fix mentioned in https://bugs.kde.org/show_bug.cgi?id=88474 isn't in the new version of arts apparently so the cpu overload problem exists on AMD64. I modified the ebuild to use the the arts-3.4.1-cpu-overload.patch and it applies cleanly and the arts sound server will work with alsa selected. Reproducible: Always Steps to Reproduce: 1.emerge arts-3.4.2 2.restart kde 3. Actual Results: arts cpu overload message is displayed after the system is frozen for 10 seconds or so.
Thanks. Added the patch to the 3.4.2 ebuild. The 3.4.1 ebuild comment incorrectly stated that the patch was applied to the 3.4 branch upstream. Actually it was only applied to trunk (now 3.5).
