Maybe it something trivial but I cannot found that I should change
I can play sound on DisplayPort when set card and device parameters, e. g. for aplay
aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav
But default device is analog output. So I can hear sound only with headphones.
Wiki article "Advanced Linux Sound Architecture, Select the default PCM via environment variable" says to set ALSA_CARD. But all my devices have the same name PCH.
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC887-VD Analog [ALC887-VD Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

I've tried another tip, with .asoundrc
.asoundrc
pcm.!default {
type hw
card 0
device 3
}
and it works partially: now sound plays on DisplayPort but headphones don't work anymore.
As far as I understand I need to configure auto-switch DisplayPort <-> analog when headphones are (dis)connected. How can I do it?
Update
I guess it the same question as [SOLVED] Automute speakers on plugging in headphones? But I don't install PulseAudio and auto-switch doesn't work.

I think that someone should detect that headphones' jack is (dis)connected.
I've watched with dmesg --follow and journalctl --follow - no any messages when I connect or disconnect it.
And looks like Cubi doesn't support the detection of headphones jack.

As far as I know, on a device setup like this, analog and digital outs are mutually exclusive, you can only use one at a time, this is a driver/hardware limitation
