udev may be having adverse impacts on abilities to play sounds from certain
cards after reboot. Anyone interested may find sound devices in black
listed category they don't want to have black listed. Correcting such
black listing for now is beyond my capability since I haven't done enough
with udev to be safe working with ityet.
Sorry, now I see you have multiple sound cards.
My fault I should have mentioned it, sorry: That's it!
Since 2015-12-11 my /etc/modprobe/alsa-base.conf ist:
# PCH
options snd-hda-intel index=0 model=auto vid=8086 pid=9c20
# HDMI
options snd-hda-intel index=1 model=auto vid=8086 pid=0a0c
this is (if I remember correctly) from Arch wiki and should
provide a numbering of sound devices such that the analog device
becomes default (first one). Since then I could hear music, hear
sound from movies but only till a week ago.
If I delete this file and reboot, the numbering of devices is:
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 0: ALC3232 Analog [ALC3232 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
Now mplayer -ao alsa:device=hw=1.0 works but aplay wav still does
not, mplayer does not without the command line switch and
interestingly mpd still works.
How to tell linux that the analog device is the default device?
(I'll come back to this mailing list when I actually want to hear
sound through the HDMI device).
Thanks a lot! This at least gives an explanation!

3 Options:
1.
from http://alsa.opensrc.org/MultipleCards:
...
The newer "slots=" method
Alternatively, you can use the slot option instead of the index options:
options snd slots=snd-interwave,snd-ens1371
Then, the first slot (#0) is reserved for snd-interwave driver, and the
second (#1) for snd-ens1371. You can omit index option in each driver if
slots option is used (although you can still have them at the same time as
long as they don't conflict).
...
2.
Move the unwanted soundcard to an empty seat:
find your card location with:
$ loginctl seat-status seat0
[long list]
...
/sys/devices/pci0000:00/0000:00:1b.0/sound/card0
...
[long list]
Attach the card to an other seat:
sudo loginctl attach seat1 /sys/devices/pci0000:00/0000:00:1b.0/sound/card0
Now you can only use the card when you login on seat1, but as long as you
don't
attach a monitor, mouse and keyboard, the seat won't work. Note root can
still
access the card as all users in the audio group can. (That why I asked you to
remove yourself from the audio group)
3.
Blacklist the module, so nobody can access the card.
