Did you check with alsamixer to see if Main or PCM or anything else has been |
58 |
muted? |

PS. I seem to recall on a dell machine where the sound would be muted |
61 |
inexplicably (I believe due to some hardware setting) that dual booting into |
62 |
MSWindows would fix it (i.e. unmute it). As the alsa drivers were developed |
63 |
further this problem disappeared a few months later. |
