OK, thanks.

Could the src/include/soundcard.h file also be updated in the next
version? Right now it contains this:

 * Modifications to this file are NOT allowed. This header file controls the
 * OSS API. For compatibility reasons only 4Front Technologies can make changes
 * to the definitions.

It seems the latest version is available in a standard BSD license.
