I have also noticed a problem with my Virus ti Snow since updating to the latest beta OS. The USB audio stream is not synced properly. I am getting a waring message when starting up the Virus VSTi in Cubase 5.5.3 (32bit) which says:
ZitatVirus TI has discovered a setup problem. The host is using an odd audio interface buffer size which causes communication problems. Please adjust the buffer size to any of the following sample values instead: 64, 128, 256, 512.
This message has only appeared after installing 4.5.1.15. NO previous version of the OS displayed this error.
I have a problem though because my audio interface is an Edirol UA-1000 USB interface and It does not display buffer sizes in samples. I have no way of knowing what the buffer size is in samples. Cubase reports the buffer size in milliseconds, which is currently 10.907ms.
How can i solve this without having to:
A. buy a new audio interface
B. rolling back my Virus OS.
