Thank you for your help. I turned on the computer, changed options snd |
| 77 |
cards_limit to 2 and ran aplay /usr/share/sound/alsa/*.wav (I have a |
| 78 |
different named wav files). There was a sound. Then I started Firefox |
| 79 |
and opened some youtube videos. The sound was present as well. Then I |
| 80 |
opened alsamixer. Some of the channels were muted and some had no full |
| 81 |
sound. Nevertheless, the sound had been present. I unmuted all the |
| 82 |
channels and set the full sound level on all of them. Then I again |
| 83 |
checked that the sound is present. It was. So, I rebooted the |
| 84 |
computer, ran alsamixer and made sure that all channels are unmuted |
| 85 |
and have full sound level. But this time the sound was absent exactly |
| 86 |
as I expected. Neither aplay nor Firefox produced any sound. I have |
| 87 |
already seen this behavior when I experimented with the kernel |
| 88 |
configuration about 8 months ago: the same kernel options, the same |
| 89 |
configuration files, all alsamixer channels are unmuted but after one |
| 90 |
reboot I have a sound and on another I have no sound. Any thoughts? |
