Changing the buffer size in Asio driver mode
As I understand it, when you use Asio drivers, you must change the buffer size in the sound cards Asio control panel instead of the using the buffer slider. However, when I try to change the buffer size via the Asio panel in my M-Audio ProFire 610 while Sonar is running, the controls (buffer size, sample rate, etc.) are grayed out (non-operational,) Therefore I have to close Sonar then open the ProFire control panel (at which point the controls are accessible) and make the requisite changes and then reopen Sonar. So my question is this: Is that normal? Do other sound cards allow you to change the buffer size while Sonar is running? And for those of you who use the ProFire 610, do you experience the same thing or is this just a problem with my system? I would appreciate any help/feedback because A: I'm trying to learn as much about this kind of stuff as I can, and B: it is quite a hassle having to close and reopen Sonar every time I want to change the buffer size.
And on a similar note, the bit depth control in the options > audio dialog box is also grayed out, and that's not something I can change via my sound cards software control panel (whether Sonar's running or not.) I remember changing it at one point from 16 to 24 bit (where it is currently stuck) but I don't remember how. I guess it wasn't grayed out at the time. Any thoughts on that? I guess I could temporarily switch to another driver mode and see if the control then becomes operational again and if so then change it and then go back to Asio mode. But again this seems like an unnecessary hassle. Again, any help would be much appreciated. Thanks in advance.
