You have to post the pulseaudio verbose log when you playing stereo using
4.0 profile
surround40 of emu10k1 is using multi plugin with two slaves front and rear
EMU10K1.pcm.surround40.0 {
@args [ CARD ]
@args.CARD {
type string
}
type multi
slaves [
{
pcm {
@func concat
strings [
"cards.EMU10K1.pcm.front.0:CARD=" $CARD
]
}
channels 2
}
{
pcm {
@func concat
strings [
"cards.EMU10K1.pcm.rear.0:CARD=" $CARD
]
}
channels 2
}
]
bindings [
{ slave 0 channel 0 }
{ slave 0 channel 1 }
{ slave 1 channel 0 }
{ slave 1 channel 1 }
]
}

Did you get any sound from rear jack?
speaker-test -c2 -t wav -D rear:0
You need to use gnome alsa-mixer to find out which mixer controls affect
front, rear jacks by playing stereo or mono audio to front, rear and
hw:0,0 devices
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/SB-Live-mixer.txt
The master volume only control ac97 analog mixer which is connected to
front jack and won't affect rear jack
I2S DAC connect to rear jack has no volume control, you need to use those
DSP volume controls and add those "Wave xxx volume" to those pulseaudio
conf files
