| Notaris | Anyone around who could help me debug why a TechnoTrend TT-TVStick CT2-4400 is not working on my linux box? I am running Debian wheezy with backported kernel 3.16.0-0.bpo.4-amd64 and compiled the media_build driver
The kernel messages look ok to my (blind?) eye: http://pastebin.com/6b398fds | [20:03] |
| TrSqr | let me see | [20:04] |
| Notaris | Ok. Just tell me what additional info you might need. | [20:05] |
| TrSqr | yep, looks good, loads the correct firmwares
how does it not work? I mean, what are the symptoms you are experiencing? | [20:05] |
| Notaris | Hardware should be ok, as I tested it once on my work laptop. I got a channels.conf and had it working with vlc on the laptop. Now if I use this same channels.conf on my desktop with vlc, I do not get a picture. vlc (started from terminal) is not very verbose, just says [0x1ab3108] main libvlc: VLC wird mit dem Standard-Interface ausgefu:hrt. Benutzen Sie 'cvlc', um VLC ohne Interface zu verwenden.
[0x1cdd898] main playlist: stopping playback [0x2345128] main stream error: cannot pre fill buffer ...and does not start playing TV. I am not bound to use vlc for watching TV, any working alternative would be ok. Just don't know where to look for an error. | [20:07] |
| TrSqr | I'm unfortunately rather vlc illiterate. can just make a simple channel scan using w_scan or dvbv5-scan to see what it says?
is this DVB-T or DVB-C? | [20:10] |
| Notaris | It has a DVB-T, DVB-T2 and DVB-C tuner and/or demodulator built in.
http://www.linuxtv.org/wiki/index.php/TechnoTrend_TT-TVStick_CT2-4400 | [20:11] |
| TrSqr | yes, I know, I've written that page :)
but what are you trying to receive? | [20:11] |
| Notaris | ok. Sorry, misunderstood the question. I am trying to get the DVB-C signal
...and sure, I can do a w_scan or anything else. I had done a w_scan (some weeks ago, when I bought the stick) before. Tuned through the frequencies for some 15 minutes without finding a single channel. In contrast, when hooked to my work laptop to the same antenna cable, I found all channels which are now residing in the channels.conf. | [20:12] |
| TrSqr | the thing is, if the application does not support multiple standards for one adapter, you need to change the mode before trying to use it
quite many applications do not still do that dvb-fe-tool -a 0 -d DVBC/ANNEX_A | [20:14] |
| Notaris | What also might be important to know, I first had tried the binary driver from Technotrend which was no success either before switching to the media_build driver. Might there be some old closed source stuff interfearing? | [20:14] |
| TrSqr | that should change the delivery system to DVB-C
based on the dmesg output you should be ok but if you have a recent w_scan (the one that comes with your distro could be age old), it should handle multiple delivery systems per adapter ok | [20:15] |
| Notaris | I first had tried directly vlc with no success, than had switched with dvb-fe-tool -d DVBC/ANNEX_A and tried again. No improvement. your suggestion with -a 0 on top also did not help | [20:17] |
| TrSqr | ok :/
and w_scan -fc does not find anything either? | [20:17] |
| Notaris | wscan seems to be from 2012: Package: w-scan (20120605-1)
http://pastebin.com/ra9wmReF Just started a w_scan run (see beginning in link above). If it is the same as last time, it will take some 15 minutes and not find any channel. Bear with me.... | [20:19] |
| TrSqr | ok.. 2012 is age old :) but maybe it should still work | [20:22] |
| Notaris | Come on, jessie release is still some weeks ahead and w_scan will seemingly only get updated to a version from end march 2013 :( | [20:24] |
| TrSqr | proper DVB-T2 support came in the July 2014 release...
but I guess DVB-C should be ok | [20:26] |
| Notaris | DVB-T2 is not yet broadcasted in Germany. Might come in a few years. Probably even enough for Debian to catch up with......
On my work laptop, I am running Ubuntu 14.04 which comes with w-scan (20130331-1), likely the same version that will only come with Debian Jessie in a few weeks. That could explain the non-successful scanning on my desktop. However, does this also explain why playback of TV is not working? I would assume w-scan is _only_ needed for building the channels.conf?!? BTW, 11 minutes and counting of w_scan and no channel yet 850000: sr6900 (time: 12:45) sr6875 (time: 12:48) 858000: sr6900 (time: 12:50) sr6875 (time: 12:53) ERROR: Sorry - i couldn't get any working frequency/transponder Nothing to scan!! So, no channels found... :( | [20:27] |
| TrSqr | but the laptop using the same driver works, or did that have the closed source driver? | [20:34] |
| Notaris | Complete console output: http://pastebin.com/AHBRP55t
No, on the laptop I only used the open source driver without messing before with the closed source TechnoTrend driver | [20:34] |
| Any other idea what to do? Anyhow, thanks already now for taking time and trying to help out! | [20:47] | |
| .... (idle for 18mn) | ||
| TrSqr | I'm quite short on ideas, unfortunately. I'd try compiling a recent w_scan still, but maybe that won't make any difference.
everything looks good, but you just don't get a lock (which you do using the same driver and device on a different PC) oh, this is the problem: 44. [ 5015.713245] si2168 6-0064: downloading firmware from file 'dvb-demod-si2168-b40-01.fw' [ 5024.543938] si2168 6-0064: firmware version: something's wrong with the demod you should see it print the firmware version | [21:05] |
| Notaris | ok, that means to download the firmware file again from OpenELEC dvb-firmware collection? | [21:08] |
| TrSqr | http://trsqr.net/olli/dvb-demod-si2168-b40-01.fw
take that, it's a bit newer.. | [21:09] |
| Notaris | Then unplug and replug the DVB-Stick? | [21:11] |
| TrSqr | we'll update the firmware in OE later when we have a kernel in OE that supports the new firmware format, but so far there's still the "old" one
Notaris, that should do it.. or just remove the module and modprobe it again | [21:11] |
| Notaris | Whow! That was quite an experience. Unplugging and replugging almost seemed to crash the computer: http://pastebin.com/vM8pVdWu
Also the "old" kernel problem?!? | [21:14] |
| TrSqr | hmm.. no idea really. | [21:16] |
| Notaris | I could do a reboot to start from a clean state... does that sound reasonable? | [21:17] |
| TrSqr | yep, definitely :) | [21:17] |
| Notaris | Ok, I'll be back ;) Thanks for all the help, give me a minute or two..... | [21:17] |
| *** | Notaris has quit IRC (Quit: Notaris) | [21:18] |
| Notaris | Now the first part looks good: http://pastebin.com/awNfVRt3
What do I do to make it load the firmware: Start w_scan again? | [21:27] |
| TrSqr | yep. anything that tries to use the tuner | [21:27] |
| Notaris | Looks great!
http://pastebin.com/PJa7cZzs :) Firmware version 4.0.11 | [21:28] |
| TrSqr | yes, much better now
so, does it work? | [21:28] |
| Notaris | w_scan output is different from last time. No channel found yet (that was also some 10+ minutes into the scan on the laptop), but I am quite hopeful! I'll let you know as soon as w_scan is through!
Now there is also the little green LED light working on the stick, which was not the case before on the desktop! :) | [21:30] |
| TrSqr | yep, I use the same tuner in my living room for dvb-t and dvb-t2 | [21:33] |
| Notaris | w_scan is finding channels. :) That looks excellent. DVB-T is not a real alternative, the signal is coming from an antenna only 3,3 km away, but I never received all available channels, no matter which hardware I tried.... :( | [21:41] |
| TrSqr | allright, sounds good then!
anyways, time to get some sleep - if it still doesn't work it has to wait until tomorrow. but it will, no worries :) | [21:44] |
| Notaris | Ok. Thank you very much for your help!!!!
I am quite confident that it will work! | [21:46] |
| TrSqr | yep. not a problem! | [21:47] |
| Notaris | Good night!
It works! Seems that it was indeed the firmware file (corrupted during download?!?!) | [21:47] |
