If changing the .asoundrc required a reboot there'd be no way for two different users to have two different versions of it.

I renamed my fancy .asoundrc to something else and rebooted and the SPDIF still works. I must say I wasn't expecting that - what an easy config that is!

You should be able to set it to auto-detect the sound format, which will allow you to use PCM and AC-3 and ...

If you are sure the receiver is working correctly, you might want to
try replacing the device number in this statement:
# Alias for digital (S/PDIF) output on the Audigy (hw:0,0)
# Do not use this directly--it requires specific rate,
# channels, and format
pcm.digital-hw {
type hw
card 0
device 4
}
I would try each number 0-4. Requires a reboot, but well worth it if
you get the right one. The SPDIF on my board (Asus A7N8X-E Dlx)
onboard coax digital out is 0,1. I have an optical header that I
haven't used yet but I would think that cycling through those numbers
would help. Good luck! Also, instead of creating the file .asound in
HOME I created the file /etc/asound.conf and it works for all users,
root etc.

[mythtv-users] Can't get S/PDIF sound working
I've just bought a S/PDIF header for my Gigabyte mobo and am having
trouble getting any sound out of it.
I've taken the Jarod's .asoundrc which in turn was taken from the
DigitalSoundHowTo at
http://www.mythtv.info/moin.cgi/DigitalSoundHowTo. Jarod said that he
only had to change 4 lines to get his working. The main thing seemed
to be getting the device number right. The output of "aplay -l" gives
me:
[elm|~]$ aplay -l
List of PLAYBACK Hardware Devices
card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 0: Intel ICH [Intel
82801DB-ICH4]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 4: Intel ICH -
IEC958 [Intel 82801DB-ICH4 - IEC958]
Subdevices: 1/1
Subdevice #0: subdevice #0
So I assume my S/PDIF device is number 4 - is that correct?
My .asoundrc looks like this:
