Also I have no idea why a sound sequencer > ioctl should work on /dev/pts/0 :) ioctl numbers are not always unique (I haven't checked if this is the case here). But it might be that it's some other ioctl actually. One easy way to check is to install debuginfo and set break points on ioctl in gdb and then look at the sources in the backtrace. -Andi -- ak@linux.intel.com -- Speaking for myself only.
