Thanks for make that clear.

I expand the command a little and the result is:
# lsof +c0 | egrep 'snd|dsp' | cut -d' ' -f1 | sort | uniq
I changed my pulseaudio to system mode instead of user mode in
/etc/default/pulseaudio. Now I have Built-in audio under system audio
settings and sound is working. In user mode there was no sound.
Permission problem? Do I need some special permission to use audio
device under pulseaudio?
Previously I reboot my system into single user mode and was able to
use speaker-test successfully. So ALSA definitely detect my card.
alsamixer master volume was 0 so I need to change before. Under Gnome
every audio slider is on max even alsamixer one. The output under
single user mode:
Hardware PCM card 0 'HDA Intel' device 0 subdevice 0
Its setup is:
stream : PLAYBACK
access : RW_INTERLEAVED
format : S16_LE
subformat : STD
channels : 2
rate : 48000
exact rate : 48000 (48000/1)
msbits : 16
buffer_size : 16384
period_size : 4096
period_time : 85333
tstamp_mode : NONE
period_step : 1
avail_min : 4096
period_event : 0
start_threshold : 16384
stop_threshold : 16384
silence_size : 0
boundary : 4611686018427387904
appl_ptr : 0
hw_ptr : 0
Playback device is hw:0,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
0 - Front Left
1 - Front Right
In short. Under single user mode I am able to use speaker-test after
setting master volume to non zero value. Under Gnome there is sound in
system mode pulseaudio but no sound in non system mode.
