hint.sbc.0.flags

[Jan Stary]

Hello,

I am using a SoundBlaster AWE64 on FreeBSD 5.4-RELEASE-p6.

The snd_sbc manpage says

	hint.sbc.0.flags="0x15"

	The value of flags specifies the secondary DMA channel.  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.

How do I find out whether my card  "has a secondary DMA channel",
and whether it is "C"? 

	Thanks
		Jan
