Besides upgrade (sudo apt upgrade) and reboot I didn't change anything. Before upgrade everything was ok.
Help?
Looks fine. The green light turning off is just fine, it simply show that nothing is playing.
What exactly are you doing to play test tones?
I tested with vlc, ffplay and web browser. Green light doesn't go on and there is no sound.

Please use sox and post the output:

No green light, no sound

One more detail: After reboot RPI4 the green light goes on for a few seconds then it goes off.
That's perfectly fine. That shows that some process already used the sound card. If it does not go on when playing via sox, this shows that sox isn't using the sound card. Might be a broken /etc/asound.conf.
There is no /etc/asound.conf.
That's might be one problem. I also see that you're card is number 2 which means that there is probably other stuff configured (e.g. onboard sound). You will either need to disable this or make sure that output goes to card 2.

Thanks - this is very strange - before this upgrade to 5.4.79 (it was 5.4.74) everything worked well...
With a new file /etc/asound.conf there is no change - still no sound.
What's the full output of
aplay -l
(I guess you have removed something as the card is listed as card2)

Disable onboard sound
Hi, I have the same problem. No sound, unable to play youtube videos.
The music player turns on the green light, but the sound does not play.

Is was working until you did an update?
Please do not say "I have the same problem" if you don't. This is about an upgrade. Please create a new topic, otherwise this will be very confusing to other users.
I found a config.txt option to turn off onboard sound with:
force_pwm_open=0
and this did the job - the sound is back again!
Thank you.
That's strange and interesting ;-)
It should be
dtparam=audio=on
I've never heard about the force_pwm_open option. Not sure, if this is something that has just been introduced.
Checked your option as well and this is working, too - sound is on.
But the strange thing why these changes are necessary when upgrading kernel from 5.4.74 to 5.4.79 will be unsolved I guess..
It might not have been caused by the kernel, but by PulseAudio:

Oh, I missed that – you are certainly right ;-)
Pulseaudio doesn't care about /etc/asound.conf
