It seems that this is a general problem for USB tuners on Linux with Plex running inside a docker container. (Plenty of people affected) I did have a look to that page and those instructions but concluded that everything should be available inside the docker container. I double checked if my host/hardware could be causing this issue. i ran a tvheaded docker which worked fine with my USB tuner. Yes, I checked permissions. All looks fine, furthermore as stated before, tuner works in a different container. So a this point - for me - it seems that the Plex container is causing the problem. ---

I’m not expecting a fix this soon but just knowing that someone is working on it would be nice. Many thanks in advance! I don’t have any update Do you have a windows machine you can install a temporary test environment on for Plex Media Server to see if it works ok on windows on the current release 1.21.4.4079-1b7748a7b Are you able to test both dvb-c andn dvb-t and establish if the issue is just dvb-c on linux/docker ? ---

> [@Xiaolom](#): > > This is not only a linux issue. It is a generel problem with usb tuners on DVB-C. I see it on a Synology NAS and Windows and a MacBook. A working USB DVB-C Dongle will not find any station. I´ve seen a lot of posts here having that issue. My guess it has to do with a wrong XMLTV file. But nobody answered my request. Guess I´m quitting after my test-month then I replied to one of your other posts with this: what lineup/guide are you using after entering country and post code ? What post code ? and any tuner channels visible on the setup screen (on left side) Do you have a windows machine you can try Plex Media Server on to see if dvb-c scanning works ? What DVR make / model ? Is it USB or networked? Logs covering setup / scan of the issue on synology and wndows comparison would be useful see [https://support.plex.tv/articles/201643703-reporting-issues-with-plex-media-server/](https://support.plex.tv/articles/201643703-reporting-issues-with-plex-media-server/) [https://support.plex.tv/articles/200250417-plex-media-server-log-files/](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) ---

Hi @sa2000, I found the problem on my side (should have seen it earlier)… Could have sworn the correct firmware file was in the kernel already for the Hauppauge devices but apparently not. I ran e.g. dmesg so many times and never saw the error: ```auto [499707.765054] si2168 10-0064: Direct firmware load for dvb-demod-si2168-02.fw failed with error -2 [499707.765071] si2168 10-0064: Direct firmware load for dvb-demod-si2168-02.fw failed with error -2 [499707.765074] si2168 10-0064: firmware file 'dvb-demod-si2168-02.fw' not found ``` The following post triggered me: > [@HAUPPAUGE WinTV-quadHD Live TV & DVR Setup - No Channels Found](https://forums.plex.tv/t/hauppauge-wintv-quadhd-live-tv-dvr-setup-no-channels-found/213590/12): > > Oh, you are running windows, then it is something else.

Thanks for the feedback. If we are to document firmware update - it would need to be referencing Hauppauge web pages rather than github OpenELEC repo. There are these Happauge web pages [Hauppauge | TV Tuners for Plex](https://www.hauppauge.com/pages/products/data_plex.html) [Hauppauge Support | Linux](https://www.hauppauge.com/pages/support/support_linux.html) Do we need to ask Hauppauge to update these ? There are DVR model specific lnked pages [Next page](https://forums.plex.tv/t/dvr-setup-fails/680640.md?page=2)
