Your camera's sound card is not shown here (stating the obvious). |
| 24 |
|
| 25 |
Have you tried building it as a module and modprobe -v <driver> to see what |

I would suggest that you build alsa as modules at least for troubleshooting |
| 48 |
purposes. I had to do that in the past to get things working in a box, |
| 49 |
following the recommendation of the devs. |
