  • LibreELEC with updated dvb drivers

    Thank you for your answers.

    The sticks are:

    1) Astrometa T2 Hybrid DvbT/T2/C/Analog/FM Stick (15f4:0135): works with updatelee drivers.

    Had problems with normal kernel drivers and with media build drivers. It doesn't work in Libreelec 8.2.5 and 9.0

    2) Geniatech HDStar Dvb-S2 v 3.0 (14fd:3000) (old version, not with m88ds3103b): works with updatelee drivers

    It doesn't work in Libreelec 9.0 but works in 8.2.5

  • Does this dvb s2 tuner work?

    I can only say that I've compiled kernel from updatelee / v4l-updatelee — Bitbucket and it works perfectly.

    Also my Astrometa T2 Hybrid (Dvb-t/t2/c) works with that drivers.

    Had problems with normal kernel drivers and with media build drivers (tvheadend coudn't scan or tune any channel).

    Didn't make a diff to the sources to see what's different though.

    By the way, it could be very useful to insert updatelee / v4l-updatelee — Bitbucket drivers as an option in the milhouse builds.

    Milhouse, do you think it could be possible?

    Thank you,

  • Does this dvb s2 tuner work?

    Thank you CvH

    from LinuxTV

    Geniatech HdStar (2.0 and 3.0) : Cypress CY7C68013
    Terratec Cinergy: Cypress CY7C68013A

    Dvbsky S960: Cypress CY68013

    Technotrend TT-connect S2-4600: Cypress CY7C68013A (saw on another site)

    Remember to have read somewhere a while ago that they were all quite the same box with different names (in fact bought Geniatech at € 34 because costs less).

    Maybe the final "A" makes difference?

    Sometimes they change components without changing names.

    Anyway, there a problem in the latest Milhouse builds (standard drivers), because the box works perfectly in 8.2.3.

    Bye,

  • Does this dvb s2 tuner work?

    Don't know if it can be useful for this topic, but I own a Geniatech Hdstar Dvb-s2 box, which should be a twin of Technotrend (and also of Terratec cinergy dvb-s2).

    Same Tuner Montage 2022 and demod Montage M88DS310

    Noticed that in my config the box is always recognized, but tuner fails (no signal in the latest Milhouse builds). It works perfectly in Libreelec 8.2.3.

    So tried also in Ubuntu and these are the results:

    A) Ubuntu 17.10 with media_build drivers compiled from git://http://linuxtv.org/media_build.git

    No signal

    B) Ubuntu 17.10 with drivers compiled from updatelee / v4l-updatelee — Bitbucket

    works

    C) Libreelec 8.2.3

    works

    D) Libreelec 9.0 Default

    no signal

    E) Libreelec 9.0 Crazycat

    works

    F) Libreelec 9.0 Hauppauge

    no signal

    If it is useful can post dmesg.

    Thank you

  • Astrometa T2Hybrid

    Thank you very much crazycat for your time.

    Maybe it's something firmware related?

    Can't verify in Libreelec (can't change firmware), but in Ubuntu the firmware that works (dvb-demod-mn88473-01.fw) is 2,2k from Palosaari site.

    Bye,

  • Astrometa T2Hybrid

    Thank you crazycat for your answer.

    Tested the stick extensively, only related to dvb-t part (interested in fm also, but it seems to me no one coded drivers), and can tell that it works perfectly:

    1) with updatelee drivers;

    2) With Libreelec 9.0 default and Hauppauge drivers.

    Is it possible for you to look at that code and verify if there are differences with your drivers?

    This way with your drivers I could use all the three stick.

    Remember this is T2Hybrid (conexant 0135) and not the Realtek 0131 one.

    Thank you

  • Astrometa T2Hybrid

    A little bump on this thread.

    Tried latest milhouse nightlies with all drivers combos.

    I have three usb dvb sticks:

    1) Astrometa T2 Hybrid DvbT/T2/C/Analog/FM Stick (15f4:0135);

    2) Dexatek/Logilink/MSI rtl2832 DVBT Stick (1d19:1101);

    3) Geniatech HDStar Dvb-S2 v 3.0 (14fd:3000).

    My results:

    A) Ubuntu 17.10 with media_build drivers compiled from git://http://linuxtv.org/media_build.git

    - All three stick recognized by TvHeadend

    - Astrometa and Hdstar no signal. Only Rtl2832 works

    B) Ubuntu 17.10 with drivers compiled from updatelee / v4l-updatelee — Bitbucket

    - All three stick recognized by TvHeadend and working

    C) Libreelec 8.2.3

    - All three stick recognized by TvHeadend

    - Astrometa no signal

    D) Libreelec 9.0 Default

    - All three stick recognized by TvHeadend

    - Hdstar no signal

    E) Libreelec 9.0 Crazycat

    - All three stick recognized by TvHeadend

    - Astrometa no signal

    F) Libreelec 9.0 Hauppauge

    - All three stick recognized by TvHeadend

    - Hdstar no signal

    Now my question. There's the possibility to join together these drivers and make all my sticks work in Libreelec?

    For example, Geniatech Hdstar 3.0 works perfectly in Librelec 8.2.3 but not in LE 9.0 with default drivers? Why? There has been a regression?

    Anyway, there's the possibility to reorder this "little mess"?

    Thank you,

  • Astrometa T2Hybrid

    It works!

    The problem is that my (latest) version of T2hybrid (conexant chipset) has 88473 demod, while the firmware extracted from Index of /linux/v4l-dvb/firmware was 88472 for the T2Hybrid, and 88473 for the fm/dab (realtek chipset).

    I needed 88473 for T2hybrid.

    Just to help anyone who wants to buy this stick, will tell what I've done.

    1) Downloaded Windows driver from Astrometa site (latest version) and unzipped it, and found the .sys file.

    2) I saw from README that the firmware was extracted (i suppose with the help of an usb sniffer) this way:

    Code
    dd if=AMDVBT2BDA.sys ibs=1 skip=169296 count=2271 of=dvb-demod-mn88473-01.fw

    3) so tried to do the same for my drivers, hoping the firmware was in the same place (in the .sys windows driver), and did

    Code
    dd if=AMDVBT2Hybrid.sys ibs=1 skip=169296 count=2271 of=dvb-demod-mn88473-01.fw

    4) copied the resulting .fw file to /lib/firmware, overwriting the older, and rebooted

    Now it works (in Ubuntu).

    Didn't test extensively, but now tuning works.

    The only thing is that can't use the new firmware in LibreElec (I copied it in /storage/.config/firmware), but it seems that the old .fw is used.

    There is a solution?

    Thank you,

    How about this suggestion ?

    USB DVB-T2 HDTV Digital TV Stick Remote Receiver DVB-C DV ESY1 FM DAB - US$22.99

    Yes, I knew that.

    They're all hybrid 2832u realtek usb sticks.

    The difference is that I needed analog fm support.

    In Libreelec ther's no fm support (apart from rtl-sdr etc.).

    Also in windows these rtl2832u sticks aren't directshow compatible, as they don't expose an fm tuner dshow filter.

    Realtek has made available only a dll, so there are only few software that can use fm (and dab part).

    That is why I bought the Astrometa T2Hybrid, that has a directshow classic filter (and also analog in).

    you can try MN88472 here Index of /linux/v4l-dvb/firmware

    or try to extract yourself at AstroMeta_integrated solution (choose hybrid driver)

    Thank you so much. Didn't know that there was a specific firmware already extracted from Astrometa drivers (was thinking doing it myself). I was using 88472.fw extracted from other sticks. Maybe that is the culprit.

    Will try and report.

  • Astrometa T2Hybrid

    I've recently bought an Usb Dvb-t/t2/c analog/fm stick. I knew there was no support in linux/libreelec but in windows works very well.

    The stick is better described here: tv tuner-lte,wifi router,mifi,mobile signal booster,tv tuner,Shenzhen NewSky Co., Ltd.. It has R828D+MN88473+CX23102.

    Recently saw this: [media] cx231xx: Initial support Astrometa T2hybrid - Patchwork, and so had little hope in linux support.

    Googling i've found this: howto: ubuntu 16.04 Tvheadend DVB-C/S(2)/T & non-DVB (ipcam/DV) rotate recording, and noticed that it could be more than a hope.

    In LibreElec 8.2.3 and latest milhouse builds, both dvb-t and dvb-c are recognized, but the stick can't tune or scan any services (in tvheadend).

    DMesg reveals a tuner frequency out of range error.

    Saw in howto: ubuntu 16.04 Tvheadend DVB-C/S(2)/T & non-DVB (ipcam/DV) rotate recording that "Still compared to the Microsoft Windows driver of the Astometa DVB T2, one issue remains with the current linux tuner driver which is an issue with tuning/scanning high frequencies/muxes leading to no channels or high error rates. This is however fixable by building you're own linux kernel module from the V4L2 media_build on linux kernel version 4.10.x and applying the r820t tuner patch suggested by Эдуард Мяги."

    Tried to build in Ubuntu media_build drivers and applied the patch suggested in howto: ubuntu 16.04 Tvheadend DVB-C/S(2)/T & non-DVB (ipcam/DV) rotate recording, that is

    Code
    sed -i '0,/air_cable1_in = 0x60;/s//air_cable1_in = 0x00;/' ../media/drivers/media/tuners/r820t.c

    This way my Astrometa T2Hybrid can tune some channels, scanning still doesn't work, but better than nothing.

    Can anyone help me to make it work in Libreelec? It's a very good usb stick and costs only 22 Euro.

    Thank you

  • LibreELEC TBS 5520 SE

    Sorry to bump old thread. Was considering to buy a TBS 5520 SE. Anyone can tell me if now it works with Libreelec? Wanted to know also if in Tvheadend there are two tuners (dvb-t and dvb-s) that are switched on the fly, or if we have to switch by sotftware the tuners before using them (as in windows).

    Thnak you,

    sdf
