Public bug reported:
Dear developer(s),
I used a vdr-installation on Debian testing, before. Switched over to Ubuntu
since the release of cosmic because of problems with GPU/steam under Debian.
Now, I have problems to configure vdr because my TV stick doesn't seem to work
with kernel 4.18.
This is what I did: Installed Ubuntu, upgraded via aptitude to the latest
packages, got the firmware "dvb-demod-si2168-b40-01.fw" and
"dvb-tuner-si2158-a20-01.fw" (as it was recommended by *I guess it was*
openelec.org and the modinfo output of si2168 and si2157), tried w_scan and
failed (w_scan *can* find some signals but failes in getting the channels).
That looks like this, f.e.:
[…}
Scanning DVB-T2...
474000: (time: 01:38.796)
482000: (time: 01:43.155)
490000: (time: 01:45.163) signal ok: QAM_AUTO f = 490000 kHz
I999B8C999D999T999G999Y999P0 (0:0:0)
Info: no data from PAT after 2 seconds
deleting (QAM_AUTO f = 490000 kHz I999B8C999D999T999G999Y999P0 (0:0:0))
[…]
Now, I tried an older kernel - 4.15, because it's still in the cosmics'
repository and tried w_scan again: Success, although the TV-Stick
doesn't find all the channels I found with Debian Testing.
So, maybe there's a regression in the latest kernel regarding the TV-
Stick-driver or there is another firmware which will work better with
4.18…?
Would be glad if someone could help to work that out…
Greets!
