Tvheadend

Error -11 is EAGAIN, ie "please try again".

Maybe Tvheadend is starting before the tuner has been fully initialised by the kernel. You could try delaying the startup by a few seconds (or start Tvheadend manually) to see if that fixes the problem.

Drivers must be reinstalled after kernel update because TBS drivers have not been accepted into mainline kernel. If you don't like that then email the maintainer and complain.

Firmware files need to be installed to /lib/firmware. If you deleted them then you must reinstall.

Kernel update does not remove the old kernel. Simply select the old kernel from grub menu when you boot and it should work again if it was working before.

This is not a TVHeadend bug rather a driver bug. Go to https://github.com/tbsdtv/linux_media/issues and file a report.

I have two TBS 6905 cards and since I moved over to using the open source drivers, they have been quite stable. There is the fun of having to rebuild the drivers with kernel updates, but c'est la vie.

Which drivers and firmware are you using?

How are you disabling and enabling the TBS card?

Hello Dave,

I already try to delay the startup of TVHeadend with the same result. I have disable TVHeadend at startup and staring it after 30 minutes with the same result too.

Thanks for your help

Hello Ron,

I effectively don't ask to reinstall drivers after each kernel update but I am not complaining about this, it was just a remark.

After deleting the firmware I downloaded it agin and put in /lib/firmware, but there is no difference after a reboot.

I known this is not a bug in TVHeadend, I have just ask for the knowledge community.

Thanks for your help

Hello Thermionic,

You're right, C'est la vie! I was living with this constraint for about 6 years without any post anywhere!

I'm using the latest version of the open sources TBS Drivers https://github.com/tbsdtv/linux_media/wiki and the firmwares provided by TBS too http://www.tbsdtv.com/download/document/linux/tbs-tuner-firmwares_v1.0.tar.bz2
I have try with a different version of the firmware dvb-tuner-si2158-a20-01.fw fin on tvheadend.org with the same problem.
I have also try with the Luis Alves and CrazyCat drivers, always the same result.

I have to uncheck "Enabled", then click on "Save" and after check "Enabled" and "Save" again, this is working.

Can you tell me which drivers are you using?

Thanks for you help

I use the open source drivers, and have a little script to keep them up to date, no error handling, but it works for me https://pastebin.com/yKWXw5n3

looking at restarts of tvh in dmesg (for a daily backup), I see the below

Thanks for the script, I will try when my problem is solved.

Like I can I see in your log, youu too have some lines "firmware download failed -11" and it's working, I will investigate further.

Thanks you thermionic

Disable power save feature of tuners

Hello Saen,

Power Save is already disabled.

Thanks you

Hello,
i'm experiencing the same problem since a short time with my tvh (HTS Tvheadend 4.3-1952~gb824e237e) and a tbs6205 card.
The interesting thing is, the docker container starts up and all tuners are failing.
But when i disable and enable each of the tuners inside tvh firmware upload works and everything is fine till next start of container.
Power Save is disabled.
Probably tvh does something weired ?

peter

I've got exactly the same problem with my TBS6205 card.
Runing the latest drivers from the TBS wiki and the latest tvheadend compiled from git.
I have to disable and re-enable all 4 tuners one by one after every reboot in order for them to load the firmware correctly.
I've also opened an issue here: https://github.com/tbsdtv/linux_media/issues/259

Somebody found a workaround yet?
