It's more simple than that: if you see the bars movind in the mixer |
128 |
application, some sound should be made. |

Probably with strace or a similar tool; however, let me see first if |
134 |
I'm understanding the problem. This is a laptop? If so, the sound |
135 |
works without headphones? The internal speakers work? |
136 |
|
137 |
Also, can you please post the output of "pactl list"? |
138 |
