       •  apci97_latency=<NNN>  Certain  models  of the ES1371 sound devices will sound distorted playing stereo
          audio and setting the PCI latency fixes the problem

       •  apci_spdif=0|1 Certain models like the SB 4.1D/SB PCI128D have SPDIF output  jacks  and  this  setting
          enables the output device.
