Ryzom killing my system's sound - Technischer Support

This may be a unique situation. My sound system is part of a recording studio and I'm using a usb audio interface (Presonus Audiobox), the sound is amazing but when playing, the sound stops after a random time. Other games, videos, and other apps do not have this affect.

It requires a reboot to restore the sound.

I have noticed that when this has occurred, video in Facebook and Youtube is also disabled until the system has been rebooted.

If anyone else has had experience with this or can offer some help, it would be greatly appreciated.

Thanks
Lhyrs
