Hauppauge WinTV-dualHD USB tuner DVB-T scan no data, failed

invariant · 2 May 2019 19:21

Hi, I installed osmc on a raspberry pi 3 B+ and would like to watch dvb-t TV with my Hauppauge WinTV-dualHD USB tuner which comes with a small portable TV antenna. After booting osmc I installed Tvheadend from MyOSMC App Store. I then entered the web interface and went through the wizard but could not get any services. The Scan result in Configuration->DVB Inputs->Muxes shows FAIL for all muxes. I rebooted the raspberry and deleted the networks created by the wizard and repeadted the following steps manually

Added Network (Type DVB-T) with Pre-defined muxes (I tried with Generic auto-Default and Germany)
Disabled all other devices except one DVB-T tuner.
For Silicon Labs Si2168 #0 : DVB-T #0 I selected the defined Network from the first step.
Force Scan in Configuration-> DVB Inputs->Networks of the created network from step one.

The tv tuner is recognized:

But all scans fail:

Here is the output of uname -a

I also tried to scan using w-scan (installed using sudo apt-get install w-scan) after stopping the Tvheadend service with service tvheadend stop. The command I used to scan w_scan -f t -c DE resulted in the following output

Am I missing some settings in tvheadend or do I need another firmware/driver?
Thanks for your help!

Is the signal strength of -70 dBm enough?

JimKnopf · 2 May 2019 19:44

@sam_nazarko I fear the German DVB-T2 pre-defined muxes are missing with current release.

@invariant Have a look here: [TESTING] DVB improvements for Vero 4K take 2 - #24 by JimKnopf

As long as a correct pre-defined mux template for German DVB-T2 is missing, have a look at this post to get the idea to circumvent it.

invariant · 2 May 2019 19:52

In the dmesg output I saw that firmware version is B 4.0.11. In this post they use firmware verison 4.0.25 from Index of /linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.25.

Would it help if I followed the steps from the post:

sudo -s
cd /lib/firmware
wget http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.25/dvb-demod-si2168-b40-01.fw
reboot

Thanks @JimKnopf for you help. I followed your instructions

Add DVB-T Network:

image1124×1094 98.3 KB
Disabled Initial scan on DVB-T #0 and added the newly created network from step 1.

image1710×1388 338 KB
Selected all new muxes and did the bulk edit you described

image1710×1460 461 KB
Force scan for the network

Unfortunately all scans still fail

@JimKnopf is it possible that these mux settings are not correct for my region Ingolstadt Germany?
On this site I found an online tool to create a config file that contains some frequencies for Germany which I should copy into /usr/share/dvb/dvb-t. However this directory does not exist. Is it save to create this folder and will Tvheadend find this file in the Pre-defined muxes list? Where does Tvheadend look for Pre-defined mux config files?

Here is some content of the file:

JimKnopf · 2 May 2019 21:19

As you can see the items are just mux entries. In theory you only need to meet one mux since all muxes should transmit the NIT (network information table) which includes all other muxes. The public broadcasts provides the most reliable information.
I don’t know your tuner device but give plp_id=1 in your muxes a chance.

invariant · 2 May 2019 21:34

Thanks for the suggestion but using plp_id=1 did not help - the scan still fails. Does it depend on the tuner? And what does this setting even mean? Do you know where I can get the information needed from the public broadcast? Isn’t the tuner device the Silicon Labs Si2168? Sorry if these are stupid question but I am really not sure about all of this. Also what is a mux and how is it related to a network?

JimKnopf · 2 May 2019 21:40

Since TVheadend can see the tuner devices I would first assume all is right with driver stack etc.

Tvheadend looks at folder /usr/share/tvheadend/data/dvb-scan/dvb-t to locate the pre-defined muxes for dvb-t(2).

You can try to create a file ‘de-all’ in that directory with content

which includes all possible mux frequences for DVB-T2 in Germany. If that also does not work, there must some special with your tuner which I don’t know.

JimKnopf · 2 May 2019 21:43

Since w_scan also does not see anything with your tuners either the driver stack or the antenna/receiving condition do not work at all.

invariant · 2 May 2019 21:52

I tried already to add a new Pre-defined muxes file but this does not show up in tvheadend. Any idea why this could happening? Rebooting or start stop of tvh didn’t help either.

invariant · 2 May 2019 21:56

I will try with a DVB-C connection next week to check if there is something wrong with the tuner. Currently I am also not able to test with the original WinTV Software on Windows but I will try that too next week.

However, any help is welcome… Regarding my previous post: would it help if I try to install the latest firmware?

invariant:

In the dmesg output I saw that firmware version is B 4.0.11. In this post they use firmware verison 4.0.25 from Index of /linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.25.

Would it help if I followed the steps from the post:
sudo -s
cd /lib/firmware
wget http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.25/dvb-demod-si2168-b40-01.fw
reboot

JimKnopf · 2 May 2019 22:02

If you have created your network as DVB-T the German mux templates appear as “Germany : …” not “de anything”.

Firmware: Latest/greatest is always a good idea … but I don’t know this piece of hw.

invariant · 2 May 2019 22:13

Ok, I had to reinstall tvheadend to make de-all and aa-All appear in my list.
However, still no success with your list or the one from the online tool.

Now I will try the latest driver.

invariant · 2 May 2019 22:42

Updating the firmware did not work either. According to this page the device is supported in kernel 4.17. As far as I know osmc runs kernel 4.14. Is this correct and could this be the problem?

grahamh · 3 May 2019 12:21

Yes, 4.14. How old is the tuner, though? These things get changed. If you have the Silicon labs tuners showing up in the tvh GUI then you can assume it’s ‘supported’. Problems with scanning could be a wrong firmware issue.

But in your OP you mention a small portable TV antenna. I hope you are not trying to rely on that. They never work unless you can see your transmitter through the window.

invariant · 3 May 2019 12:35

I really don’t know where I can find that information. The page I already posted, mentions these tuners (dvb-c and dvb-t and usb) Silicon Labs Si2157, Silicon Labs Si2168,Empia EM28274

Yes I tried with this small antenna just for now to check if it is even working. I placed the antenna outside but all scans failed. Could be because of the bad weather though.
However, in the long run my goal is to use this tuner via dvb-c. I hope to get time to try this during the weekend.

grahamh · 3 May 2019 13:07

In the screenshot you posted, you have signal strength -76dB. Mine is -32dB on a rooftop aerial. Same chip.

invariant · 4 May 2019 07:03

Thanks for the information @grahamh. I guess the problem lies with the antenna. I tried another w-scan yesterday which resulted in the following for dvb-t2 (no results with dvb-t):

Can someone tell me what this output means?
Scanning with tvheadend does not give me any information about Signal Strength yesterday. I tried with the new firmware and also tried with a fresh install of osmc and tvheadend.

Using the DVB-C tuner works great though
