So, the thing is, I can hear the audio throuh my external amplifier when I'm
running mythfrontend in X11 (a vnc desktop, that's why it doesn't find Xv

It looks like you're watching a channel on the X11 version that sends a
48kHz PCM audio signal (or AC3) and one on the QT/E version that sends a
44.1kHz (or 32kHz) PCM audio signal. Nearly all sound cards require you
to send PCM data at 48KHz to a digital audio output. Since you're
sending the output to the "spdif" device, you're sending it directly to
the hardware. Instead, you should define a device which does the
appropriate conversions before sending the audio to the card.
Take a look at
http://mythtv.info/moin.cgi/DigitalSoundHowTo#head-b318f22131b4a59eef5f28edfac9160204e13719
and try using either the "ALSA:digital" or "ALSA:mixed-digital" devices
(and use either "default" or "ALSA:default" for the mixer device). You
may have to adjust the device numbers for your sound card (as described
in the page).
