That dreaded error again ... |
41 |
|
42 |
What do you get when you run: |
43 |
|
44 |
alsamixer -D hw:0 |

Try muting this just in case it makes a difference (I seem to recall it used |
53 |
to cause problems many moons ago). |

Hold on! Have you run alsactl at all? |
64 |
|
65 |
Can you please run: |
66 |
|
67 |
alsactl -d init |
68 |
|
69 |
to load the modules, probe the cards and reset all your devices. Then run |
70 |
alsamixer to adjust their settings accordingly. |
71 |
|
72 |
If all this does not help, then all I can think is that something in the sound |
73 |
drivers has changed for the worse (regression bug) and that's why you lost |
74 |
your sound. |
