Q: Why do I get an error 'Could not start ASIO' or some such?
A: (Version 1.x) ASIO4ALL requires exclusive access to the audio device. More often than not, starting the driver fails because the audio device is already in use. There are obvious instances, like some other audio application still open, but there are also things to consider that are not so obvious. Such as the "Microsoft GS Software Wavetable Synth", which is enabled as a default MIDI output in some sequencer software. Check the MIDI settings of your host application! For a further explanation on this issue, I recommend this link. Besides, this may also be related to the 44.1 vs. 48kHz issue as explained above. Try to set up a project with 48kHz and see whether this makes a difference. As a last resort, check the "Force 16 Bit Samples" option in the control panel. If it still doesn't work, report!
(Version 2.x) This error should not happen as often anymore. Instead, you simply get no audio, and, if you open the ASIO4ALL control panel, you will find that your audio outputs are flagged with an error symbol. The most likely reason and remedy for this hasn't changed, however.
