34  * A huge thanks goes to Spas Filipov for his friendship, support and his
35  * generous gift - an 'Audiotrak Prodigy HD2' audio card! I also want to
36  * thank Keiichi Iwasaki and his parents, because they helped Spas to get
37  * the card from Japan! Having hardware sample of Prodigy HD2 made adding
38  * support for that great card very easy and real fun and pleasure.
