https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D262671 --- Comment #12 from Aleksander Slomka <alex@alexslomka.xyz> --- (In reply to Ed Maste from comment #11) Thank you for the help! The patch indeed solves the issue for me. Now the `ioctl` properly returns `EINVAL`: 31415 test CALL ioctl(0x3,SNDCTL_MIXERINFO,0x8210902e0) 31415 test RET ioctl -1 errno 22 Invalid argument It makes sense that this works, since PCM_REGISTERED is checking if it's argument is equal to NULL, just like my patch did, but I don't understand w= hy the `if` statement didn't work when the condition was in reverse order. --=20 You are receiving this mail because: You are the assignee for the bug.=
