[icecast] Problem with dual streaming

Perhaps you can move the "sound_device" config option to an
"encoder_stream_set" sub-section? Don't know, though. I imagine the
resulting config would be along the lines of:

ENCODER_STREAM_SET 0
SOUNDCARD
SOUND_DEVICE /dev/dspW0
FULL_DUPLEX
SAMPLE_RATE 22050
BITRATE 16000
MONO
MOUNTPOINT 0
URL http://URL0

ENCODER_STREAM_SET 1
SOUNDCARD
SOUND_DEVICE /dev/dspW1
FULL_DUPLEX
SAMPLE_RATE 22050
BITRATE 16000
MONO
MOUNTPOINT 1
URL http://URL1

But I have no idea if the 2-5th lines of each section are valid
"sub-section" declarations....
