Well, I've decided to entirely remove foobar and reinstall it. And now, obviously, it works well, no more errors, whereas, before, error appeared very often (4 times/5).
For the plugin, I have the minimum: _console, _input_std, _ui_std, _read_http, _out_dsound_ex (direct sound 2.0), _vis_manager, and yours.
But for now, no problems, good for me.
Thank you for this nice plugin.
PS:An other question: is there any way to read the dynamic track title of radios ?
