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=20 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,=20 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 Yuriy.
