Generally, the error means that a particular soundcard cannot be used in ASIO mode as it is already in use with DirectSound/WASAPI, possibly by another application. See here for details: https://www.mairlist.com/dokuwiki/faq#bass_error_3_in_bass_asio_init_during_startup
So are you really aiming to use that card in ASIO? Tell us more about your config.
Sometimes these errors come from audio interfaces which have been removed/unplugged from the system, but the drivers have not been removed yet.
