From the ALSA wiki
Since January 2000, the latest version of ALSA includes full support for the RME Hammerfall and Hammerfall Light. The RME Hammerfall is the first professional digital audio card which can use its full potential under Linux, all 52 channels and full 24 bit resolution. The efficient driver concept allows an operation on usual PC's at 20 ms latency and full channel usage causing a CPU load between 2 and 5%.
