TBS5520 switch between dvb-s and dvb-c

It's important to keep your driver and software updated.

Could you please post the kernel version and the distro you use to test your repo?


Main development PC with Kubuntu 14.04 x86_64, installed two years ago. Now updated to 4.2 LTS kernel.
Also have some old PC with Athlon 64 3200+ and 1.5Gb DDR RAM, Kubuntu 12.04 with 3.13 LTS kernel.

I've just compiled and install the open source drivers. Now I can see in 'lsmod' the DVB-S driver and the DVB-T driver:

$ lsmod | grep tbs
dvb_usb_tbs5520 20480 4
dvb_usb 32768 1 dvb_usb_tbs5520
dvb_core 131072 2 dvb_usb,dvb_usb_tbs5520
$ lsmod | grep av
avl6882 143360 1

I work with Kaffeine and Me TV for tune and watch channels. For example, Kaffeine only detects and works with the "Availink AVL6882" (before "TurboSight TBS 5520FE DVBS/S2 frontend"). But Kaffeine nor Me TV can tune channels. These are the errors in syslog when both scan for DVB-T channels:

Tuner Locked.
i2c i2c-8: avl6882: failed to enter DVBTx mode

Furthermore how can I switch between both TV systems?

Thanks.

Hi,
With Ubuntu 16.04 x64 and Crazycat drivers inside qemu...

to change modes I've used dvb-fe-tool...

Thanks a lot Crazycat

With 3.x x64 kernel I've run fine on VLC tunning both DVB-S and DVB-T without need 'dvb-fe-tool' with Crazycat drivers. But in 4.x x64 kernel I'm unable to tune DVB-T, only DVB-S. Has anybody got the same issue than me?

TBS official drivers are still useless since they cannot tune DVB-T in Linux, only DVB-S.
