Ubuntu does not work with rtl2832u-dvb-t-chip

[criticalmess]

Binary package hint: udev

Ok, installing the driver of this chip wasn't that easy but following several "finnish"-howtos i managed to succesfully build v4l-dvb driver for the rtl2832u-chiped MSI Digivox mini II V3.0.

lsusb:

scan /usr/share/dvb/dvb-t/de-Nordrhein-Westfalen delivers all channels that i know off.

kaffeine scans all channels properly too and i can watch everything probably if i tune my antenna up to 18db, but kaffeine is kde based and i would like to have gnome/gtk based me-tv.

Me-TV cannot find ANY channels (0) when i use internal scan:
example output:

08.11.2009 15:15:43: Tuning to transponder at 538000000 Hz
08.11.2009 15:15:43: Auf Signalsperre warten … (translation: waiting for signal lock)

08.11.2009 15:15:58: Failed to tune to transponder at 538000000 Hz

So i tried to import the channels.conf-output that i generated with scan.
Me-Tv seems to work, adds all channels, but stucks heavily and cannot show tv properly due to weak signal...

After that the stick is properly found, registered and is working with kaffeine. But me-tv claims bad signal.

Howdy Michael, could you please expand on what you mean that you can not replicate?

A) you don't have the hardware to reproduce the issue

-or-

B) you have the hardware and it works fine

criticalmess, is this still a problem? If so, what is the output of "apt-cache policy me-tv"?

I cannot replicate it again, because i have no more access to the
rtl2832u-dvb-t-chip and im very sorry that i lost the link to the
finnish-manual and driver.

Please just close it if anybody claims a rtl2832u-dvb-t-chip working
with me-tv.
All new MSI Digivox mini II V3.0 seem to got those chips; the stick
itself is very cheap.
So if you really wanted so reproduce then you need to buy that stick or
look for people with hardware equiped to troubleshoot functionality.

What i can tell you is that same system with same model-brand named
usb-stick - but different chip (the af9015, which is mine) - worked
without the noted locking errors and that the driver has properly
isntalled and firmware was properly in place, because kaffeine orked on
BOTH chips.

It is possible that it has been fixed at all since a long time, i really
cant tell anymore, sry.

[Michael Lamothe (lamothe-deactivatedaccount-deactivatedaccount)]

Hi Marc, thanks for trying :) The answer was A.

[MHB (mhb-monomania)]

I have the same cheap MSI DIGI VOX mini Deluxe DVB-T stick (rtl2832u-dvb-t) as shown above. In Karmic I had similar experiences: working DVB-T for all channels in de-Niedersachsen in VLC and mplayer, but no possibility to scan or import in me-tv. Now in Lucid, again with v4l modules build as above, in Me-TV 1.1.2, scanning picks up all channels available. The only odd thing so far is that the Meters window shows a signal strength or 3% with 0% S/N ratio. Seems a little low to me, but that is probably the module rather than me-tv.

[Michael Lamothe (lamothe-deactivatedaccount-deactivatedaccount)]

So I'm assuming all is good now.

This card is not at all supported by the v4l team.

There was a working version which was not up to coding standards, but ran up / including Ubuntu's last LTS release (Lucid).
After that, the v4l version control and build system has been changed, and the driver does not compile anymore.

I have decided AGAINST making it runnable on newer kernels, as there are some people working right now on a new release.

Once the status becomes more clear, I'll update

@jan

Do you know if there's something new?
I've got the 1f4d:b803 G-Tek Electronics Group Lifeview LV5TDLX DVB-T [RTL2832U]. I tried to compile different drivers but none work. I tried them under Natty and under Oneiric and the result was the same.
You wrote that there was a driver that works with Lucid. Can you explain which is and how to compile/install it properly? By now I'm really confused, I'm trying lots of things but nothing work.
Thanks

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Frédéric Côté (frederic-cote)]

If your device work with Kaffeine, it will work with me-tv. The best way to
scan your channel is to create a "channels.conf" file with the command
w_scan in command line (you can also try "scan") then your import it in
me-tv.

What about newer version of ubuntu. The device is recognise by lsusb but it doesn't work. There's no driver rtl2832u found.

[York Wu (yorkwoo)]

I have tried Ubuntu 11.10 and Mint12. Both work successfully.
My device is UPMOST DVB190, which has device ID as 1d19:1102.

I followed steps written on the following page:
https://github.com/ambrosa/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0

After installed the compiled module, it detected my device and works with me-tv perfectly.
But I still don't get how to make VLC work.
I think it should work for all distributions based on kernel 3.0 or above.

[penalvch (penalvch)]

criticalmess, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Currently, there is a reasonable workaround:
Follow the steps under
"How to build the v4l-dvb kernel modules from the backport tree"
at http://linuxtv.org/repo/

Drivers for many rtl2832u cards are supported in the current development version.
Inclusion in a main-line kernel will follow later.

[robb990099 (rebrown)]

rtl2832u is still a problem on older kernels. Works fine otb for 3.11 e.g on Ubuntu 13.10 but I am trying to get this module compiled for any kernel that will work on sun4i i.e. armv7 such as 3.10.25 which is good on raspberry pi. The source files for the module are not available on kernel 3.4 at sunxi and neither 3.10-reference nor experimental/sunxi-3.10 will boot. Is 3.13 from Hans de Goede likely to be a better prospect?
Thanks for any pointers.

[Sinisa Radalj (sinisa1hr)]

just to mark there is no more issue on this and close this topic ,as dvbt based cards on this chip works with mod of Ambrosa mentioned above ,and that workaround is so wide tested on ubuntu international ,and my local ubuntu forum, and even is orginally made to work with kernels for 64bit machine,with add of headers can work on kernel for 32bit, as i personally test on both and on wide range NOT ONLY TV branded usb and pci cards, only on some cards extra feature of digital radio on some of them can not be enabled with just this solution.. one more thanks to mr. ambrosa and all those what he mentioned (inside).and list of vids and pids which can and work with his or sligtlly modded his solution is much more wider.Just as long as this chip is inside.

[Sinisa Radalj (sinisa1hr)]

And solution based on mr Ambrosa solution, worked with kernel started with number 2, more then two years ago.. so sure can work even now!
