Hoary and sound

I have recently upgraded to Hoary.  Sound was working fine under Warty but 
is not under Hoary.

After much fiddling around I now have system sounds but still no sound 
from anything else such as mplayer etc.

I have looked at information on Wiki and this list and have tried the 
following :

1.  I have played with alsamixer and this seemed to get the system sounds 
working.  (Is this meant to look so crude?)

2.  One of the Wiki suggestions was to modify modules.conf which I did.  I 
can't find the suggestion any more but it seemed to have no effect.

3.  On the Restricted Formats Wiki it says : Ubuntu uses a program called 
esd to allow multiple applications to access the sound card at one time. 
However, many third party applications not in Ubuntu main aren't designed 
to use esd to access the card. On some sound cards, this causes these 
applications to not produce sound. To work around this problem, esd must 
be configured to release the sound card when it is not using it. To do 
this, edit /etc/esound/esd.conf and change the line that begins with 
spawn_options to begin with default_options. Finally, change the -as 5 to 
-as 2.  Note: this problem only occurs on the Ubuntu Hoary release and 
newer. Kubuntu and Ubuntu Warty are not affected by this.

I did this and still no improvment.

4.  I installed polpaudio which removed Alsa.  This didn't seem to change 
anything.




The output from aplay -l is as follows

The computer is a Shuttle ST61G4.  The doco says it has Realtek 650F 6 
channel audio.

I was hoping this wouldn't be so complicated.

Any suggestions?

Steven
