My DAW seems to behave a bit different, but maybe it´s the same basic problem? The ASIO connection for me has Always been lost after using Wavelab for a while. Everything is is ok at boot up, but when I lost ASIO Connection it was when switching between different wav:s. Trying to refresh ASIO didn´t help. When I shut down Wavelab and tried a restart, nothing happened, because Wavelab was still running according to the task manager. So I had to shut that process down Before Wavelab started again - and after the reboot, ASIO connection was back!
I checked the wav:s I was working on when this happened (again today), and actually one of the files I was switching between was 48kHz, and the others 44,1kHz. I´m not sure if Wavelab tried to switch samplerate when I´ve lost ASIO Connection, but I wouldn´t rule that out - thus, it may be the same basic problem.
[EDIT: I can now confirm that it is when switching between wav:s with different fs that the ASIO connection is lost]
Nice to see PG responding in the other thread! Hope there is a fix soon.
