Thank you for your help. I turned on the computer, changed options snd cards_limit to 2 and ran aplay /usr/share/sound/alsa/*.wav (I have a different named wav files). There was a sound. Then I started Firefox and opened some youtube videos. The sound was present as well. Then I opened alsamixer. Some of the channels were muted and some had no full sound. Nevertheless, the sound had been present. I unmuted all the channels and set the full sound level on all of them. Then I again checked that the sound is present. It was. So, I rebooted the computer, ran alsamixer and made sure that all channels are unmuted and have full sound level. But this time the sound was absent exactly as I expected. Neither aplay nor Firefox produced any sound. I have already seen this behavior when I experimented with the kernel configuration about 8 months ago: the same kernel options, the same configuration files, all alsamixer channels are unmuted but after one reboot I have a sound and on another I have no sound. Any thoughts?
