Got list of Multiplexes but no Services + issues with tuners?

Added by Brian A over 10 years ago

I have installed tvheadend on Ubuntu server 14.04 using the ubuntu repository binaries. The install seemed to go OK.
I have a USB Satellite and a USB Terrestrial tuner attached.
I have set up tvheadend via 'Add DVB Network by location'. There is a list of Muxes for each tuner but no Services so, of course, 'Map DVB Services to Channels' is greyed out. The 'Status' tab shows the tuners but nothing happening.
I ran:
dmesg | grep dvb
It gave the results below which look good to me.
.................
[ 15.103295] dvb-usb: found a 'Technisat SkyStar USB HD (DVB-S/S2)' in warm state.
[ 15.109092] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
[ 15.116558] dvb-usb: MAC address: 00:08:c9:f0:4b:f7
[ 16.547758] dvb-usb: found a 'Hauppauge Nova-T Stick' in warm state.
[ 16.553279] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
[ 17.749793] dvb-usb: schedule remote query interval to 100 msecs.
[ 17.750327] dvb-usb: Technisat SkyStar USB HD (DVB-S/S2) successfully initialized and connected.

[ 19.127100] dvb-usb: Hauppauge Nova-T Stick successfully initialized and connected.
[ 19.129720] usbcore: registered new interface driver dvb_usb_dib0700
................

Then I ran
service tvheadend stop

and then ran:
w_scan -f s -c GB -x -s "S28E2"

Which resulted in:
..........................
w_scan version 20130331 (compiled for DVB API 5.10)

....................
I got a similar report for the terrestrial tuner.

I know that the tuners work because I have previously used them on MythTV on the same installation.

So, now I am stuck. Can anyone please suggest how I should proceed from here?

Brain dump... doesn't appear to be a tvh issue, though. Have you upgraded your OS since Myth worked?

kernel, firmware, v4l version? (some issues with 3.11 on 14.04, perhaps? also, shouldn't dmesg have firmware messages - 'downloading firmware from file xxxx.fw'?)

Stop tvheadend from even starting to see if that helps (or just ps to ensure it's shut down)

Nothing else running, as the message says?

/dev/dvb/... all present and correct?

Right version of w_scan? Compile from source? (some issues with 32-bit w_scan on 64-bit distros)

Conversely, fixing w_scan is potentially irrelevant as it may be a different problem as the adapters show in tvh. What muxes are being added in tvh by location, and are they correct (post your location and a sample frequency and I'll do some searching for you)? DVB-T and DVB-S?

The log you show is for the kernel loading the drivers, but it is not tvheadend log, we would need tvheadend log to see what is happening there. Which version of tvheadend? (ubuntu repositories contain different versions, is it stable, unstable...?)

Please make sure (inside tvheadend settings) that each adapter is enabled and that you have assigned a network to each of them. Once this happens tvheadend will start automatically scanning and finding services (for this to happen make also sure that muxes have this setting "Initial Scan Complete" unset).

For w_scan to find the cards make sure no other application is using (aka running) them (tvheandend, mythtv...).

Thank you gentlemen for your suggestions. I'll go through all that and report back.
Yes, I did check the terrestrial muxes and they were correct for a standard definition tuner. I didn't check the satellite ones because it appears that I probably have a fault common to both tuners.
