hauppauge wintv-dual hd - only see one tuner

Hi,

Thanks for your efforts on this. I'd love to switch to TVHeadEnd, but lack the knowledge of how to apply these patches.

Do you know when libreelec will support both tuners for this device out of the box?

Thanks,

Mark

No. Libreelec will not support both tuners out of the box. You would set up TVHeadEnd under Libreelec. Libreelec with Linux Kernel 4.7 and higher will support one DVB tuner. Libreelec does not support ATSC tuner currently. When this patch ([v3,2/2,media] em28xx: support for Hauppauge WinTV-dualHD 01595 ATSC/QAM - Patchwork) is accepted, Libreelec in a future Linux Kernel will support one ATSC tuner. We have to wait until technical bureaucracy of supporting two WinTV-dualHD tuners to be settled in one of the patches and placed in the future Linux Kernel. Until then, I would recommend the "unofficial" patches to get the two tuners working.

Yes, I got both ATSC tuners working for my Raspberry Pi 3.
I extracted the patch file for kernel 4.2.5 from Dropbox - wintv-dualhd-kernel-4.2.5-2016-08-10.patch.tar.xz
I used the instructions to apply the patch from Kernel building - Raspberry Pi Documentation
Code
sudo apt-get install git bc
git clone --depth 1 -b rpi-4.2.y https://github.com/raspberrypi/linux
cd linux
patch -p1 < ../wintv-dualhd-kernel-4.2.5-2016-08-10.patch

After rebooting with the patched kernel, the two ATSC tuners appeared.

Thanks leading_edjge. Now that I know it's been done, I'll have to dig in and learn how to patch the kernel. cheers.

Can anyone tell me if both of the DVB-C tuners in Hauppauge Wintv-Dual HD work simultaneously with TVHeadend on LibreElec 8?

I've tried looking for info on this everywhere but the information seems conflicting,

I already bought one tuner that only works on Windows (Astrometa DVB T/T2/C) and I don't want to repeat that mistake.

Libreelec/TVHeadend with Linux Kernel 4.7 and higher will support one DVB-C tuner on Hauppauge Wintv-Dual HD currently . You have to build the custom patches listed earlier to get both DVB-C tuners working simultaneously.

I got both ATSC tuners working for my Raspberry Pi 3 with the patch 0001-em28xx-Hauppauge-DualHD-DVB-ATSC-second-tuner-suppor.patch from Ubuntu-media-tree-kernel-builder/patches/ubuntu-zesty-4.10.0/extra at master · b-rad-NDi/Ubuntu-media-tree-kernel-builder · GitHub

I had problems applying the patch with kernel 4.9 and 4.10.

I got it working with kernel 4.11.

I assume that two DVB-C tuners are supported with this patch.

Hopefully this patch will be accepted in the future kernel (4.12 or 4.13?). A future Libreelec with the new kernel should see both tuners on the Hauppauge-DualHD.

sudo apt-get install git bc
git clone --depth 1 -b rpi-4.11.y https://github.com/raspberrypi/linux

patch -p1 < ../0001-em28xx-Hauppauge-DualHD-DVB-ATSC-second-tuner-suppor.patch

Please have a look at current submissions for Linux 4.12 kernel at kernel.org .. if it's not listed it's not been upstreamed.

elliottmc · June 3, 2017 at 8:34 AM

kernel/git/torvalds/linux.git - Linux kernel source tree

Looks like only the first tuner will be supported, so far.

But strangely enough the quadHD tuner support is in 4.11

Thanks for the info guys. I decided try order an Hdhomerun instead. It's pretty expensive but I'm not a Linux guru

sciascia88 · June 6, 2017 at 8:46 PM

I'm not very savvy in this arena, but I cannot even get one tuner listed in Tvheadend. I'm on Generic build LE version 8.0.2 and I read earlier in this topic that kernel 4.7 and up should support at least one tuner, but they won't show for me. Am I missing something?

Edit: I also tried creating a firmware file in storage/.config/ and adding all of the firmware available in this thread, but no dice. Any sort of help would be appreciated.

For the DVB-C tuner version of the Hauppauge Wintv-Dual HD, can you confirm that you have the correct firmware?

Check if /lib/firmware has the file dvb-demod-si2168-b40-01.fw.

If not, here are the instructions to getting the firmware for the DVB-C tuner version of the Hauppauge Wintv-Dual HD and putting in the /lib/firmware.

Hopefully you will able to see the first tuner.

Sorry I only have the ATSC version of the Hauppauge Wintv-Dual HD, so I cannot verify these instructions.

Thanks for replying. I believe mine is ATSC as well, North American broadcast, correct? I also have the firmware in my lib/firmware folder.

Thanks for replying. I believe mine is ATSC as well, North American broadcast, correct? I also have the firmware in my lib/firmware folder.

That firmware is only for the Si2168-B40 demodulator on the DVB-C tuner version of the Hauppauge Wintv-Dual HD. It does nothing for the North American ATSC tuner version since it uses a LGDT3306a for its demodulator.

Sorry but LibreELEC version 8.0.2 with Linux Kernel 4.9.x does not support any ATSC tuner of the Hauppauge Wintv-Dual HD.

The single ATSC tuner support of the Hauppauge Wintv-Dual HD showed up in the newly released Linux Kernel 4.11.x.

You would have to wait for a future version of LibreELEC with a Linux Kernel of 4.11.x or greater to see ATSC tuner support. You would have to wait future version of LibreELEC with a future Linux Kernel to see dual ATSC/DVB-C tuner support.

Re: Fwd: [PATCH] em28xx: add support for Hauppauge WinTV-dualHD DVB tuner — Linux media

The other option is to build a new Linux Kernel 4.11.x to make the single ATSC tuner work. If you select this option, you might as well build the patch to support both ATSC tuners.

**edit4ever** · June 9, 2017 at 2:12 AM

Any chance the work that has been done with this PPA installation could be used to get the LE kernel updated for us to use the WinTV-DualHD on rpi or amlogic boxes?

Using it I was able to get both ATSC tuners running under ubuntu!

sciascia88 · June 9, 2017 at 2:37 AM

Thanks, leading_edjge, I appreciate your help. I noticed that the current Milhouse nightly builds feature the 4.11.x kernel, so I'll probably try that. Thanks again!

woodenduck · June 16, 2017 at 6:53 PM

Did anybody get this working? I'd like to patch the latest build tonight, but I've never done any kernel patching before.

Anyone know when Libreelec would release a build with this support built in?

**edit4ever** · June 16, 2017 at 7:45 PM

The question is what platform you want it working on. Both tuners work on my ubuntu installation (after using the ppa installation) - but only one works on my rpi install running a an LE Leia alpha version.

Nothing for amlogic until someone backports the patch as it is stuck on the old 3.1x kernel.

woodenduck · June 16, 2017 at 9:59 PM

I'm on the RPi3 and running LE v8.0.2
