Jus a note that you have .10 specifics in your caps. In GStreamer 1.0,
depth and width fields no longer exists and is replaced with format=.
What is likely happening is that alsasrc picks another format, which
then looks like corrupted data. Try the following instead:

gst-launch-1.0 alsasrc device=hw:0,0 num-buffers=1 ! audio/x-raw,rate=48000,channels=6,format=S16LE ! filesink location=/tmp/test.pcm

Note that you could use wavenc before filesink to create a raw file
playable by normal media players.

Nicolas
