Re: [alsa-devel] [PATCH - alsa-lib 1/1] add surround21 for Echo3G devices

Compare these these two conf:

http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/conf/cards/SB-XFi.c...

http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/conf/cards/CA0106.c...

BOTH of them shows that the four "stereo" ports they have exist as "device", but the SB-XFi.conf does not use the multi plugin to bind them to provide a surround PCM like CA0106.conf; instead it can simply use the "front" PCM, apparently.

These two cards are different, emu10k1 have "rear" device, "centerlfe" and "side" devices

but they use multi plugin instead of surroundxx use pcm.front
