I've tested sound thoroughly on my ICH3M system (T23) and it works 
exactly the same before and after suspend.  I had a problem about a year 
ago where it would hang and stop delivering interrupts a short time 
after playing music after resume but that was fixed by Warner's pci 
power commit.  I haven't tested the R32 sound after resume but will 
check it.  It's probably similar to your R40 so it may exhibit the same 
problem.  It's my wife's so I have to be able to grab it from her and 
reboot to FreeBSD to test.  :)
