1. Did you make all the modifications recommended in the Installation Chapter of the Manual?
If not, please do so. Post back here what you find, or if you had made the changes.
2. There are additonal changes recommeded in the Troubleshooting Tips Chapter. Try them also if you are still getting audio drop-outs.
3. How much RAM do you have in the computer? Be sure your Virtual Disc is set as outlined in the Troubleshooting Tips. This can definitely have an effect.
We modified the Thread Priorities in Hoster 2.212 so that audio always had top priority. Thus, I "believe" that Hoster is not at fault here, but your computer environment needs some tweaking.
BTW: Hoster 2.213 is now released. You can come and get it for free.
