Summary:                    Playing surround sound produces 100% CPU load
Description: 
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.

But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.

Please update alsa-utils to the same version of alsa-lib

speaker-test -c 2 -t wav

speaker-test -c 4 -Dsurround40 -t wav

speaker-test -c 6 -Dsurround51 -t wav
