PCTV 292e Stick fails DVB-C

Merlin Steuer

Hey Guys,

I installed tvheadend 3.9.2514. I plugged in my brand-new PCTV 292e stick, which is supported from Kernel 3.16 and above.

The Problem I have is, that TVH detects it as an DVB-T Stick, but I want to watch my DVB-C cable TV. Manually editing the config files does not work, since TVH resets this setting on every save. (And - even if not saved and modified - it does not load the 'Select Networks...' Dropdown...).

Can someone help? Another post in the Forum suggests that from TVH 3.9 on you should be able to set the interface type. I cannot find such option.

Thank you very much and best regards,

Merlin

your probably missing the firmware

type


dmesg | grep firmware

If you get a error stating a .fw file failed to load, theres your problem.

I think these are the correct files required for a 292e


sudo wget http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/dvb-demod-si2168-02.fw -O /lib/firmware/dvb-demod-si2168-02.fw
sudo wget http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/d8da7ff67cd56cd8aa4e101aea45e052/dvb-demod-si2168-b40-01.fw -O /lib/firmware/dvb-demod-si2168-b40-01.fw

Thanks for your reply.

The only message I get is:

[ 35.803706] si2168 1-0064: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'

firmware files are present in /lib/firmware.
DVB-T works fine as well, it just can not see the 292e as DVB-C-Frontend.

stolen from an openelec forum thread I tried the following for an Astrometa DVB-C/T/T2 stick and it did work for me

rm -f /dev/dvb/adapter0/frontend0

ln -s /dev/dvb/adapter0/frontend1 /dev/dvb/adapter0/frontend0

Change adapter0 to your needs and restart tvh. It seems that tvh uses just frontend0 to determin the transport

Hi,

I have the very same problem with the same PCTV card and TVHeadend. However I have noticed, that if prior to running TVH you would run w_scan setting system to DVB-C then TVH would recognize the card as DVB-C (!) Very weird! There must be something fundamentally wrong here. However showing DVB-C does not solve anything as still scanning frequencies which have tv channels on (w_scan detected) shows nothing in TVH!!

I've checked VDR on the same platform and it properly decodes and shows everything.

My platform is: Linux raspberrypi 3.18.7+ #755 PREEMPT Thu Feb 12 17:14:31 GMT 2015 armv6l GNU/Linux

use Jaroslavs patch from here: https://tvheadend.org/issues/2711#note-10

or wait till it's included in git, this should fix your problems (at least working fine for me now)

Sadly, this does not work for me since I cannot compile TVHeadend after

git apply a.patch

OK Was told the Problem is my old DVB API 5.4...

How can I update this API to 5.5 or newer?

Not answering the specific comment above, just providing additional info. This is tvh 4.0.5-50.1 and the "grep firmware" will not yield anything:

[ 570.360330] si2168 7-0064: si2168: found a 'Silicon Labs Si2168' in cold state
[ 570.360364] si2168 7-0064: si2168: firmare file 'dvb-demod-si2168-02.fw' not found

As "firmware" is mis-spelt. Grab that fw from http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/

With that I get as far as finding channels. Thanks again Antti (Kiitos paljon). Are the checksum errors anything to worry about?
