Aureal sound cards support

	Hi current-users,

first here are the PCI device IDs for two (quite old) sound
cards from
Aureal.

Apparently there is no driver for them. About the process of
porting one:
- which existing driver would be the most appropriate to
start from?
(Linux OSS or ALSA, other BSD...)
- same question for an equivalent driver in NetBSD.

HTH,

FreeBSD apparently has a driver:

   http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/so
und/pci/ --  
see au88x0.[ch].

NetBSD does not currently support any Aureal hardware.

Cheers,
Jared

Very nice!

You are missing quite a few function callbacks required by
the NetBSD  
audio framework. trigger_output and trigger_input are very
important,  
for example  A kernel
built with the DIAGNOSTIC option would catch  
this. From audio.c:

#ifdef DIAGNOSTIC
	if (hwp == 0 ||
	    hwp->query_encoding == 0 ||
	    hwp->set_params == 0 ||
	    (hwp->start_output == 0 &&
hwp->trigger_output == 0) ||
	    (hwp->start_input == 0 &&
hwp->trigger_input == 0) ||
	    hwp->halt_output == 0 ||
	    hwp->halt_input == 0 ||
	    hwp->getdev == 0 ||
	    hwp->set_port == 0 ||
	    hwp->get_port == 0 ||
	    hwp->query_devinfo == 0 ||
	    hwp->get_props == 0) {
		printf(": missing methodn");
		sc->hw_if = 0;
		return;
	}
#endif

Hope this helps,
Jared
