snd_emu10kx from ports now does not support separate /dev/dsp devices
for rear/center/sub channels. It
plays the same sound on front and rear speakers.
The same driver in -HEAD does support "pseudo-multichannel" - you will
have to provide separate stereo
streams for front/rear outputs and separate mono streams for center/sub.
You can't play single 5.1 stream
without demultiplexing it. Your system will see your card as two (4.0),
four (5.1) or five(7.1) separate pcm devices.
snd_emu10kx will not be MFC-ed into RELENG_6. I can update audio/emu10kx
port with "multichannel" driver,
if you want to try it under 6.x.
Please also keep in mind that there are two different sound card
families both labeled 'SB Live':
- old one, with emu10k1 DSP, is supported by snd_emu10kx / snd_emu10k1
drivers, mostly 4.0 sound
- new one, without DSP, usually labeled 'Live 24' or similar. This cards
are not supported by snd_emu10kx or snd_emu10k1
