I wish I could get Sonar to use the Focusrite's non-ASIO driver, but if I recall there was an issue with inputs only the ASIO driver let me use all the channels on the Scarlett. I'd have to find another app which uses the ASIO driver (suggestions?), and then also test Sonar with something other than the ASIO driver. I could eliminate #a and #b by trying to use the ASIO driver and Sonar independently of each other. c) There is a conflict between Sonar and the ASIO driver something is happening in Sonar which causes the ASIO driver to overload or crash (or vice versa), which results in a drop-out. b) Sonar's audio engine is buggy and dropping out on its own (and the Focusrite ASIO driver is still working fine). I can think of three possibilities: a) The Focusrite ASIO driver is buggy and dropping out on its own (and Sonar is still working fine).

Because the problem only arises when using Sonar (which is the only app I use which uses the Focusrite ASIO driver), the problem seems to be software rather than hardware. until a few minutes later, at which point the sound stops again. If I restart Sonar, the sound works again. I also noticed once that there was CPU activity during the dropout, even if playback was stopped.
When I try to restart playback, I just get crackle. It's almost as if the ASIO driver (or the Sonar audio engine) "crashes", but there are no error messages. Basically, after using Sonar a few minutes, the sound suddenly stops. It's only when using Sonar (which is the only application I have which uses the ASIO driver) that I have encountered the problem. This is because I listen to music on the Scarlett all day long (Foobar, Windows Media Player, VLC, various games, etc.) and have been doing so ever since I got the Scarlett many months ago.
