If the secondary DMA channel is C, set the flags to (C | 0x10). For a sound card without the secondary DMA channel, the flags should be set to zero. .Sh HARDWARE The .Nm driver supports the following sound cards: .Pp .Bl -bullet -compact .It Avance Asound 110 .It Avance Logic ALS100+ .It Avance Logic ALS120 .It Creative SB16 .It Creative SB32 .It Creative AWE64 .It Creative AWE64 Gold .It Creative ViBRA16C .It Creative ViBRA16X .It ESS ES1681 .It ESS ES1688 .It ESS ES1868 .It ESS ES1869 .It ESS ES1878 .It ESS ES1879 .It ESS ES1888 .El .Sh DIAGNOSTICS .Bl -diag .It sb_dspwr(XX) timed out.
