hi this is my first post. i have just built my precise pangolin 12.04 LTS and wanted to use MythTv to watch digital tv however there was no plug & pray and despite running lsusb which shows it is there it is not found

it9015 & 7 firmware is present, v4l media library applied but i still cannot get it to find it

any help gratefully recieved, but please remember i am a newbie to this

ps i know it is not the dvb-t tuner dongle as that works perfectly on windows

many many thanks in advance for your help

Hi and welcome,
By what isn't your device found, only MythTv? The most important part is if a /dev/dvb/ device exists.
Seeing you mention lsusb, posting the relevant output would help a lot. Check the dmesg output for any possible errors.

Serafean.

hi thanks for welcome and response

it is not recognised by anything, have tried metv and a few others. not sure how to check /dev/dvb stupid question but what command do i need

thx again
keef

Hi,

the command neede to check the existence is "ls" just run in a console. But since your device isn't found by anything, I'd guess that it doesn't exist.
Could you post the relevant lsusb output? Google hasn't found anything dvb-related using it9015 as a keyword. Would you mind posting a link to your product?
To explain what I'm trying to do here : I'm trying to get enough information about your device to assert whether it is supported under linux or not. The best case scenario is that there will be a perfect match on this page. If not, an usbid match is usually enough. From that page you can also get information about the kernel version your device became supported in.

Hi I have 2 DVB-T tuners and neither work on Linux PP but both work on windows I must be doing something wrong

it is a mini DVB-T dongle and is pictured on one of the help sites saying it needs firmware it9017

the 2nd is a Yuan HP EC300 express card

this doesn't seem to work either

alas i'm very new to linux so all help gratefully recieved

thx keef

your link list noted above shows it as Markings Mini DVB T

the pic certainly matches, maybe i don't have the correct it9137.fw firmware, where can i get it from?

thx keef

Update

I've given up with the ITE DVB-T tuner and since it seems to recognise the YUAN EC300 DVB-T tuner card i ran w-scan
which resulted in going thru all the channels and ending with this

802000: (time: 15:00)
810000: (time: 15:18)
818000: (time: 15:35)

842000: (time: 16:29)
850000: (time: 16:47)
858000: (time: 17:05)

ERROR: Sorry - i couldn't get any working frequency/transponder
Nothing to scan!!

HELP: please - what am i doing wrong

keef

Hi,

First off : make sure which version of the tuner you have; the page specifies that version 2 of the Zolid tuner is only supported since version 3.4; an update might be needed. If you're not sure about the firmware, and in the case you decide for an update, here is a quick guide for it.

For your second tuner : you mentioned you had windows; does it manage to scan something there? Try connecting it to a better antenna.
FYI : specifying which country you are in will shorten the scan period. (w_scan -c <country_code>).

Serafean

hi many thx

TUNER1
on the Zolid tuner i guess it could be version 2, linux doesn't tell me but i have been back to original packaging which alas also doesn't tell me
i did follow the instructions you mention earlier but the it9137.fw firmware instructions don't work

./get_dvb_firmware it9137
says not recognised so is there anywhere else i can get the firmware from?
can i upgrade to 3.4 with ubuntu i wonder?

TUNER2
swapped aerial and added a booster
tried using w_scan -c GB but it still ends with

834000: (time: 48:34)
834167: (time: 48:52)
833833: (time: 49:16)

ERROR: Sorry - i couldn't get any working frequency/transponder
Nothing to scan!!

???? why i wonder, this tuner works perfectly on windows on the same laptop,
yours puzzled

thx keef

PS it does scan channels and works in windows

Hi,
yes : http://kernel.ubuntu.com/~kernel-ppa/mainline/

yes : http://www.ite.com.tw/uploads/firmwa...usb-it9135.zip
The get_dvb_firmware script is only packaged since kernel 3.3, sorry, I missed that part.

the tuner2 not being able to find anything is really weird. Try looking through logs and the module debug info (if you're up to it) to figure out if there is a problem in the driver.

Serafean

thx will try those all and let you know how i get on
