Even with the USB power management fix the problem of losing the second tuner still persisted albeit less often. Curiously, the power supply in my machine failed (a Dell OptiPlex 520 - Small Form Factor) and I connected the machine up to a bigger power supply from another machine. The second tuner has been fine for 4 weeks now without a single reboot. |

Revision as of 23:29, 7 September 2012
A dual tuner DVB-T PCI card from Leadtek.
Currently supported by recent V4L-DVB (as at Sep 2010) The card is not working out of the box, however there is a solution (patch to V4L really).
Your mileage may vary. There are still some issues in using this card; please read on.

Making it work in Ubuntu
Updated 24 June 2012
I made a simple GUI which installs Leadtek DTV2000DS, configures the remote control for Mythtv and fixes the missing second tuner.
https://github.com/map7/tvconfig
Updated 29 October 2011 by Mrgrrr
Running Mythbuntu 11.10 the card works on this kernel but need the firmware bellow sudo apt-get install linux-firmware-nonfree
In Brisbane I have had odd results with channel 9, first time showing this station fails to lock but after checking other channels it then works.
Enjoy
Updated 14 May 2011 by BenWise.
Two channel tuning on this card (at least) now works out of the box on kernel 2.6.38 (taken from Ubuntu PPA).
I use Mythbuntu 10.04.
To upgrade Mythbuntu 10.04 to use 2.6.38 kernel:
# get the firmware version 4.95
sudo apt-get install linux-firmware-nonfree
# upgrade kernel to 2.6.38
sudo add-apt-repository ppa:kernel-ppa/ppa
sudo apt-get update
sudo apt-get install linux-headers-2.6.38-1-generic linux-image-2.6.38-1-generic
Then shut down your computer (important if you've been trying to load this card already, as the correct firmware will be loaded) and turn it on again... You should have the card operating correctly now.
I expect this means the card is supported out of the box on 11.04 (as it uses 2.6.38 kernel) but haven't tested this yet.
Updated 20 Nov 2010 by AMX.
Here is a simple HOWTO/Workaround to get this card working . This is based on debian flavours. Although there are some people that have come up with shell scrips and patches to get something similar, it is better that everyone knows how things are done, and also hopefully this will be incorporated into the new releases of V4L. Until then we all have to sweat it a bit!!
The real solution is based on the bug found in http://www.xpmediacentre.com.au/community/tuners/41937-leadtek-dtv2000ds-4.html . There is another issue that better get fixed and it is to do with I2C byte write numbers.
Please leave comments in the discussion session or put comments in http://www.xpmediacentre.com.au/community/tuners/41937-leadtek-dtv2000ds-4.html so that we keep this updated.
1- Starting from a clean install of 10.04 or 10.10, perform the initial steps to install V4L drivers
sudo apt-get install mercurial linux-headers-$(uname -r) build-essential
2- go to http://linuxtv.org/hg/v4l-dvb/rev/abd3aac6644e and click on the "bz2" link and download the file.
Note: Here I am referring to a specific tag of the repository, i.e. abd3aac6644e. If you have recent kernels such as 2.6.36, you may need to grab the latest source rather than this particular tag. The rest of the process is still the same.
3- run
bzcat v4l-dvb-abd3aac6644e.tar.bz2 | tar xv
cd v4l-dvb-abd3aac6644e
This should create a directory called v4l-dvb-abd3aac6644e
4- Do the following modifications
4.1- The small_i2c fix: This fix is from discussions here http://www.spinics.net/lists/linux-usb/msg37741.html .
Edit the file linux/drivers/media/dvb/dvb-usb/af9015.c and replace
static struct tda18271_config af9015_tda18271_config = {
.gate = TDA18271_GATE_DIGITAL,
.small_i2c = 1,
};
with
static struct tda18271_config af9015_tda18271_config = {
.gate = TDA18271_GATE_DIGITAL,
.small_i2c = TDA18271_16_BYTE_CHUNK_INIT,
};
Then edit the file linux/drivers/media/common/tuners/tda18271.h
and replace
enum tda18271_small_i2c {
TDA18271_39_BYTE_CHUNK_INIT = 0,
TDA18271_16_BYTE_CHUNK_INIT = 1,
TDA18271_08_BYTE_CHUNK_INIT = 2,
};
with
enum tda18271_small_i2c {
TDA18271_39_BYTE_CHUNK_INIT = 0,
TDA18271_16_BYTE_CHUNK_INIT = 16,
TDA18271_08_BYTE_CHUNK_INIT = 8,
TDA18271_03_BYTE_CHUNK_INIT = 3,
};
4.2- The main and the nasty bug i.e. the if_sample_freq bug: This fix is from http://www.xpmediacentre.com.au/community/tuners/41937-leadtek-dtv2000ds-4.html .
If you have a quick look inside the file (just out of interest), you will notice that how this bug was messing up all the tuner frequency calculations. The frequencies are given in Table 41 in the datasheet (http://www.nxp.com/documents/data_sheet/TDA18211HD.pdf)
Anyway
edit the file linux/drivers/media/dvb/frontends/af9013.c
and replace
/* TDA18271 uses different sampling freq for every bw */
if (state->config.tuner == AF9013_TUNER_TDA18271) {
switch (bw) {
case BANDWIDTH_6_MHZ:
if_sample_freq = 3300000; /* 3.3 MHz */
break;
case BANDWIDTH_7_MHZ:
if_sample_freq = 3800000; /* 3.8 MHz */
break;
case BANDWIDTH_8_MHZ:
default:
if_sample_freq = 4300000; /* 4.3 MHz */
break;
}
}
with
/* TDA18271 uses different sampling freq for every bw */
if (state->config.tuner == AF9013_TUNER_TDA18271) {
switch (bw) {
case BANDWIDTH_6_MHZ:
if_sample_freq = 3300000; /* 3.3 MHz */
break;
case BANDWIDTH_7_MHZ:
if_sample_freq = 3500000; /* 3.5 MHz */
break;
case BANDWIDTH_8_MHZ:
default:
if_sample_freq = 4000000; /* 4.0 MHz */
break;
}
}
5- Compile and install the drivers
make sure you are back in the v4l-dvb-abd3aac6644e directory
make config
sed -i -e "s/FIREDTV=m/FIREDTV=n/" v4l/.config
make
sudo make install
wget http://palosaari.fi/linux/v4l-dvb/firmware/af9015/5.1.0.0/dvb-usb-af9015.fw
sudo cp dvb-usb-af9015.fw /lib/firmware
6- Shutdown (you have to shutdown)
7- Startup
8- Hopefully now your tuner is recognized and works happily. If not, double check the process, check for errors that might have been missed, and if it all fails, post to a forum.
Fix for the 5.1 Firmware
[Comments added by Ross] As per the notes added by Cloggy below the 5.1 firmware causes issues if you just follow the guide above. However there is a patch missing which enables support :) This is based on the following commit: http://linuxtv.org/hg/~anttip/af9015/rev/6904cb7bd11d
Replace linux/drivers/media/dvb/frontends/af9013_priv.h with the following file:
Frequent lockups during live TV and recording of TV shows
[Comments added by Cloggy - based on Mythbuntu 10.10] Using the firmware mentioned above (5.1.0.0) on my system resulted in frequent lockups during recording or watching live TV. Mythbackend.log has entries "Poll giving up", "Device error detected" and "Stream handler died unexpectedly". The previous firmware version is more stable. To use the previous version replace the "wget" line in step 5 with:
wget http://palosaari.fi/linux/v4l-dvb/firmware/af9015/4.95.0.0/dvb-usb-af9015.fw
Remember to do a cold boot afterwards to activate this firmware, /var/log/messages should show "af9013: firmware version:4.95.0"
[Comments added by Cloggy - 14 Mar 2011 - based on Mythbuntu 10.10 / Myth 0.24]
Firmware 5.1.0.0 works fine after using fix mentioned by Ross. Still only 1 tuner working. Second tuner only works on rare occassions.
Losing 1 tuner
[Comments added by Cloggy - 30 Jun 2011 - based on Mythbuntu 11.04] I noticed that the second tuner would only work after a cold boot. After a while it would lose that tuner and the only way to get it to work again was to cold boot. This seems to be caused by power management on the USB bus. Even though it's a PCI card, it actually contains a VIA USB chip that the AF901* are connected to. Disabling the power management on the USB bus fixed this problem. Similar problem is described here for a Haupage card: http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-500#Losing_one_tuner.3F
I fixed mine by adding this to /etc/init.d/rc.local:
# Turn off USB power management to keep both DVB tuners running
echo -n -1 > /sys/module/usbcore/parameters/autosuspend
[Comments added by Cloggy - 08 Sep 2012 - based on Mythbuntu 11.04] Even with the USB power management fix the problem of losing the second tuner still persisted albeit less often. Curiously, the power supply in my machine failed (a Dell OptiPlex 520 - Small Form Factor) and I connected the machine up to a bigger power supply from another machine. The second tuner has been fine for 4 weeks now without a single reboot.
Cold Boots
ATX power supplies when switched off still supply 5V to the motherboard which will keep various components and USB devices powered up so that functions like Wake on LAN can work. The 2000DS is a USB based device with a pair of USB tuners connected to the VIA USB->PCI bus interface chip. Power cycling by using the power button isn't enough in some cases to bring the malfunctioning 2000DS to a true cold boot state. To do a true cold boot (to replicate the act of pulling out a USB device) make sure the mains power cord is removed - some PSUs have a rocker switch that will do the same job - and wait about 10-20 seconds for the 5V bus to shut down completely before reapplying power. This was the only way I could get a pair of recently unresponsive 2000DS cards to start working again - the ATX power button cycling wasn't enough.
Remote Control Support
I (Gregoryo) have had no success with the remote, but there is hope from dmesg:
[ 22.263721] input: IR-receiver inside an USB DVB receiver as /devices/pci0000:00/0000:00:0e.0/0000:02:0a.2/usb2/2-1/input/input5

So I've been using /dev/input/event5 in my tests. I have tried using evtest, mode2, and irw to no avail. I get no indication of any signal coming from the remote. Am I missing a kernel driver module?
Remote Control Support (2)
[Comments added by Cloggy - 23 May 2011 - update based on Mythbuntu 11.04 / Myth 0.24] The tuner card itself works fine out of the box, you just have to copy the firmware file to the correct directory:
cd /lib/firmware sudo wget http://palosaari.fi/linux/v4l-dvb/firmware/af9015/5.1.0.0/dvb-usb-af9015.fw
However, I spent two weeks trying to get the remote control (Y04G0051) to work with the new kernel 2.6.38 and it's been a frustrating experience. The remote control emulates a keyboard but it very often generates more keypresses than what was put in. For example, you press CANCEL twice but the driver recognises three key presses so you end up in menu screens you didn't intend. Playing around with the delay and repeat settings didn't make any difference. I've also experimented with inputlirc but this didn't resolve my problem. A friend donated a Chinese made MCE remote control (what used to be sold in Australia as a Jaycar MCE remote control) and it's been fantastic! It emulates a keyboard so no LIRC required. Only problem with it is that some keys generate Shift+<some key> codes and MythTV doesn't differentiate between upper and lower case so you just have to remap some keys. All is described here:
http://www.mythtv.org/wiki/Generic_HID_%22MCE%22_Remotes
To get you started, here my ~/.Xmodmap
keycode 22 = Escape Escape Escape Escape keycode 27 = R R R R keycode 39 = S S S S keycode 33 = p P P F13 keycode 56 = B F14 B F14 keycode 41 = F F15 F F15 keycode 28 = t T t F16 keycode 58 = F17 F17 F17 F17 keycode 52 = Z Z Z Z keycode 38 = A A A A
[Comments added by Cloggy - 14 Mar 2011 - based on Mythbuntu 10.10 / Myth 0.24] Here my config files to get the remote control (part number y04g0051) working:
