Hi Rui,

the HDSP is a HDSPe, IOW a PCIe card, an ALSA device.

[rocketmouse at archlinux ~]$ cat /proc/asound/cards
 0 [HDSPMx579bcc   ]: HDSPM - RME AIO_579bcc
                      RME AIO S/N 0x579bcc at 0xfdff0000, irq 18
 1 [EWX2496        ]: ICE1712 - TerraTec EWX24/96
                      TerraTec EWX24/96 at 0xbf00, irq 20
 2 [EWX2496_1      ]: ICE1712 - TerraTec EWX24/96
                      TerraTec EWX24/96 at 0xbb00, irq 21
