I've finally tested this on my old 4.1 sound card and I've come up
against the same problems. First off I can confirm that I never hear
anything out of the rear speakers using totem-gstreamer. Secondly I
can't get gst-launch-0.10 to do the right thing with a multichannel wav
(compared to the output produced by aplay). I shall spin this second
issue off into a bug of its own so lets focus on the first issue here.

Description of the problem:
Totem-gstreamer doesn't output sound through the rear speakers despite the 
audio output being set to 4-channel/4.1-channel/5.0-channel/5.1-channel .

Steps to reproduce:
(assuming you have a working surround soundcard with 4 or more speakers 
correctly attached)
1. Disconnect your front speakers.
2. Run
speaker-test -Dsurround41 -c 4 -twav
Note that "Rear Right" "Rear Left" are announced through the rear right and 
rear left speakers respectively.
3. Download and extract
ftp://ling.lll.hawaii.edu/pub/greg/Surround-SDL-testfiles.tgz
4. Run
aplay -Dsurround41 Surround-SDL-testfiles/chan-id.wav 
Note how "Rear Left" "Rear Right" are announced through the rear left and rear 
right speakers respectively.
5. Start totem .
6. Go to Edit -> Preferences. Select the Audio tab and change the Audio output 
type to 4.1-channel. Click close.
7. Go to Movie -> Open and select Surround-SDL-testfiles/chan-id.wav . Click 
add.

Expected results:
Audio file to start play. "Rear Left" "Rear Right" are announced through the 
rear left and rear right speakers respectively.

Actual results.
Audio file to starts playing. No sound is heard at all.

How reproducible is the problem?
The problem is reproducible every time.

Additional information:
Soundcard is a 4.1 Creative Labs SB Live! EMU10k1 (rev 07)
gst-launch-0.10  filesrc  location=Surround-SDL-testfiles/chan-id.wav ! 
wavparse ! audioconvert ! audio/x-raw-int, channels=6 ! alsasink 
device=surround41
produces sound but not the correct sound compared to aplay. It announces 
"Centre" from the rear left speaker and "Rear Left/Rear Right" simultaneously 
from the right hand speaker.
