Hi!
After some testing and retrieving the output of aplay -l and aplay -L, I
get a functional configuration. My .asoundrc (if somebody needs it in
the future):
pcm.!default {
type plug
slave.pcm "hdmi"
}
ctl.!default {
type hw
card 1
}
pcm.!hdmi {
type hw
card 1
device 7
}
ctl.!hdmi {
type hw
card 1
device 7
}
