well I just learned something new: |
| 34 |
|
| 35 |
nick@media:/var/log$ ivtvctl -Y |
| 36 |
ioctl: VIDIOC_QUERYCTRL |
| 37 |
Brightness = 383 |
| 38 |
Contrast = 63 |
| 39 |
Saturation = 63 |
| 40 |
Hue = 0 |
| 41 |
Volume = 58880 |
| 42 |
Mute = 0 |
| 43 |
|
| 44 |
|
| 45 |
So there are volume and mute controls that are configurable from ivtvctl, like this: |
| 46 |
|
| 47 |
ivtvctl -y mute=1 (will mute the output - set -0 to unmute) |
| 48 |
ivtvctl -y volume=integer. |
| 49 |
|
| 50 |
The volume allegedly has a range of 0-65535 |
| 51 |
|
| 52 |
Check them out, the vol may be zeroed, or the mute set. |
