The net/speakfreely 7.2 package per default is configured with half duplex.
Yet the kernel tells me the old sb16 sound card I plugged into it supports

sb0 at isapnp0 port 0x220/16,0x330/2,0x388/4 irq 5 drq 1,5
sb0: Creative ViBRA16S PnP Audio: dsp v4.13
audio0 at sb0: full duplex, mmap, independent

So I configured speakfreely with full duplex instead by using


and ran it.  Now sfspeaker complained about not being able to open the
audio device upon receipt of audio samples to play and after a short
while, the machine froze solid to a point that I had to power-cycle it.

Get some i386 pc with a sb16 card installed, install the speakfreely
package with full duplex configured, start sfspeaker and let sfmike
connect to localhost and then play around with it a bit.
