No, it is broken since the linux_mmap changes (since some months).

I would like to see this problem solved without the need to change a
sysctl.

Ariff, what does this do? It seems it only changes the sound part, and
not any other linux mmapped region. So what is the impact of allowing
this by default and removing the sysctl?

Bye,
Alexander.
