Bug/problem: scanning on DVB-S cx24120 hardware not possible ("scan no data, failed" )

Added by a b over 6 years ago

I have this card: https://www.linuxtv.org/wiki/index.php/TechniSat_SkyStar_S2

and its using this driver: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/log/?id=refs%2Ftags%2Fv4.6.4&qt=grep&q=cx24120

VDR can scan and then i can tune into the channels that have been find.
When i remove VDR and install tvheadend (4.2 or 4.0) i always get while scanning the message: scan no data, failed

I tried kernel 4.6 and 4.4 and both didnt change much. I reinstalled fully the system - no difference.

In irc linuxstb told me to contact perexg but he was not online at the moment.

I dont know what i could do to fix this problem.

Yes. As you can see in the dmesg i am using LibreELEC. The link you post is from LibreELEC.
In the last line of the dmesg its written "[ 10.864158] cx24120: FW version 1.20.58.2"

Without the file as far as i know nothing would work. Also not VDR.

Same problem here.

016-08-15 20:38:57.000 mpegts: 10906V in Astra - scan no data, failed
2016-08-15 20:38:57.000 subscription: 00CD: "scan" unsubscribing

but I try a dvb-fe-tool --femon and the signal is good.

zofiel elzofio, did you tune into Astra 19.2? If yes, could you try this frequency:
DVB-S, Frequenz 11836 MHz, Polarisation H, Symbolrate 27500, FEC 3/4

Set modulation to AUTO.
