No signal on DVB-C with MyGica T230A #269
Comments
|
try mainline media_build or latest kernel 5.15+ |
|
I'm using Debian 5.15.5-2 kernel. |
|
T230A not supported in 5.15 kernel ? |
|
T230A is supported in 5.15 |
|
Why is it closed? |
|
I think LNA before tuner IC prevent DVB-C receiving. Check in windows |
|
Checked in Windows and found channels. |
|
myGica was always weird on DVB-C. For my original T230, I need to "hotstart" it with progDVB before using DVBviewer, or it won't get signal also. Maybe something similiar is happening here? |
|
Same issue here. |
|
Same issue with T230C under 5.15.0-56-generic |
My T230A worked at 6.1.13 and 6.x series kernels. However few weeks ago I get no signal at all. |
Hi,
I have MyGica T230A usb tuner, kernel has recognized it, but there's no signal on DVB-C.
Also, I have T230C tuner too and it's working perfectly.
Maybe this commit is not enough for T230A to work correctly with cable?
