That's for the SI. by the looks of it.

Unfortunately, PulseAudio is known to have problems with OpenAL Soft versions 
before 1.11 (or 1.10 with Pulse versions 0.9.20 or earlier). By default, 
OpenAL Soft 1.8 will try to use ALSA, which will be forwarded to PulseAudio. 
You can try disabling ALSA's mmap, which could improve compatibility. You can 
do that by adding this to ~/.alsoftrc:

[alsa]
mmap = off

If that doesn't work, you can try updating OpenAL Soft, or uninstall 
PulseAudio.
