Ubuntu – How to install a Gadmei TV Tuner (UTV380)


How do I install a tv tuner Gadmei UTV380 (Hybrid). I've been searching around the internet.

Everytime I run TVTime it always detects my webcam as a Video Source.

If you have more than a video source (which seems to be your case), you must specify which one is going to be used by tvtime in order to get the images.

In order to know which are your video sources you can drop this in a terminal: ls -l /dev/video* and you must have an output like this:

geppettvs@DYLAN:~$ ls -l /dev/video*
crw-rw----+ 1 root video 81, 0 2012-04-17 19:53 /dev/video0
crw-rw----+ 1 root video 81, 1 2012-04-17 19:53 /dev/video1
crw-rw----+ 1 root video 81, 2 2012-04-18 17:54 /dev/video2

Then you must try with each different video source, tvtime usually starts from 0, so you try from /dev/video1 with this command in a terminal tvtime --device=/dev/video1

If everything is ok then you'll see the TV signal in a window. If it drops an error please edit your question with the output of your terminal in order to edit this answer with an advice/solution.

  • Expected issues: Video but no sound. Be warned.

Additionally, if you face sound issues or no-sound while playing the tv station, just try this in a terminal, change the 48000 value for whatever your broadcast can stand for, in certain cases 32000 is good enough but it depends on your tv tuner.

tvtime --device=/dev/video1 | arecord -D hw:1,0 -r 48000 -c 2 -f S16_LE | aplay -

Good luck!
