|
| 57 |
thank you for your quick response! :)) |
| 58 |
|
| 59 |
short question before starting a new adventure :) |
| 60 |
|
| 61 |
Did specify this in /etc/modprobe.d/alsa.conf or in |
| 62 |
/etc/conf.d/modules (I am asking due to the "option" keyword...) |
| 63 |
|
| 64 |
Do you use udev? |
| 65 |
|
| 66 |
...will start the new audio adventure next morning ... its |
| 67 |
to late to keep my eyes open... |
| 68 |
|

Best regards, |
