SPDIF output broken with alsa (Xonar D2 card)

Question

Hi,
since the last time I used the SACD player, foobar2000 under wine, I get no sound from my digital port. The config had been working for a few years by then, and usually foobar gets in the way of other applications using alsa, but when the application gets killed, everything works again.
I can see on my DAC whether it is fed input or not and I checked that the hardware is set up properly through windows (dual boot).
I have tried now everything I can think of and nothing works. I have no .asoundrc since I am the only user on the PC. My /etc/asound.conf looks like:
/etc/asound.conf wrote:
pcm.!default {
    type plug
    slave {
        pcm "hw:0,1"
    rate 96000
    format S24_LE
pcm.headset { # playback only on frontpanel headset
type route
slave.pcm dmixer
slave.channels 2
ttable.0.0 1 # headphones front L
ttable.1.1 1 # headphones front R
defaults.pcm.rate_converter "speexrate_best"

I also checked the modules, nothing is blacklisted there. With this config, I get the error "Slave PCM not usable".
I also installed pulseaudio to check pavucontrol for a change, where it only recognizes the analog 7.1 output from the card (the first one listed above), not however the digital SPDIF.
What can I do ?

Answer 1

Addon:
aplay -D hw:0,1 file.wav
does not give any output either.
If the subdevice is specified, I get:
aplay -D plughw:0,1,1 file.wav wrote:aplay: main:722: audio open error: Device or resource busy
but lsof /dev/snd turns out empty. Pulseaudio is not installed.
I am really at a loss here
