Tvheadend

Were there two tuners when you had just one card?
With just one card, were there two frontends?
What is the dmesg output?

When I just had one TV card with two tuners I remember that I could watch a TV channel and record another one at the same time.
I'm not sure, though, if there were two frontends visible.

The (relevant) output of dmesg is attached.

Thanks for your help.

Looks like driver is not matched to your linux kernel. Not sure if that is the problem, but might be a good idea to update drivers. I never played with these cards, but here is a link to someone else's instructions for drivers:[[https://tvheadend.org/boards/5/topics/15440?r=15720#message-15720]]

Thanks for this hint.

I do have the newest drivers installed. And I noticed that the new V7 card is registered, not the old one. Furthermore, when I remove my old V5 card the error messages are gone.
So, I guess it has something to do with the mixed setup of two different types of cards. I contacted the manufacturer.

Hi Gerd,

I have exactly the same Problem.

An DD cine s2 v5.5
An DD cine S2 v6.5

Newest driver an the v6.5 is working, but the 5.5(ngene) gives me the same error.

Did you came further with help from the Manufacturer?

I tried the DKMS drivers an also the drivers build from source.

Here's the recommendation from Digital Devices

Please try to use the media_build_experimental driver that was built by the user mango in the easyVDR forum. It is built for Ubuntu 14.04 (trusty) but should work for 16.04 as well:

https://launchpad.net/~mango-vdr/+archive/ubuntu/my-others

Prior to installation, please remove the dddvb driver and the extra.conf file:

sudo rm -rf /lib/modules/KERNELVERSION/extra
sudo rm /etc/depmod.d/extra.conf

With these drivers, both cards were recognized successfully, tvheadend showed 4 adapters. Everything looked fine, however, signal quality was so low on the new card (V7) that it could not be used. I could only watch TV with the old card.

I went back to the newest driver to be able to use the v7 card, and I'm still waiting for an answer from DD.

You could give this driver a try and let us know if it works for you.

I tried it, but doesnt work for me.

Iam thinking about to change my Kernel to an older one, maybe 3.16, in that case the driver for the 5.5 isnt already in Kernel.
maybe it works. I try it maybe this evening.
