Notes on WinTV-quadHD install problems....

General Discussions Plex Features

Reporting this here in case it helps anyone else trying to install one of these on a 16.04 Ubuntu system.

So, I got a new WinTV-quadHD ATSC board (Hauppauge model 165100, rev B4I6) and installed it, followed the directions here:

http://www.hauppauge.com/site/support/linux.html

I get a kernel panic on boot.

I followed some Ubuntu pages and found that there is apparently some problem with the 4.4.0.83 kernel on some hardware that is causing this, and it seems that is what their most recent kernel is based on (4.4.0-83201707011420). In fact, even the Ubuntu kernel of that version crashes and I had to roll it back to the 4.4.0.81 version.

Here was a bug report I followed on Ubuntu:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1703091

In fact, I followed through the posts there, looking at trying the latest upstream kernel, which was v4.4.79 at this point, and it worked as well, but the video driver does not yet recognize the quadHD card.

My hardware:

DMI: System manufacturer System Product Name/P6T, BIOS 1408 09/21/2010

Since I was running a 4.4.0.81 kernel before this, I thought I would try the Hauppauge version based on that… 4.4.0-81201706200620. That does not kernel panic on boot, but it seems to be crashing when trying to initialize a (networking?) module. It isn’t a fatal crash, as the system boots, but I see them in the system log:

Wanting things to work right, I thought I would regress one step further, looking at the next oldest listed in the Hauppauge repo… So, I rolled it back to their version based on 4.4.0-78201705311620 and it seems to finally be working and no errors like the above in the system log.

Interesting. I have 16.04 Ubuntu Server with Kernel 4.4.0-83201707011420 and the DVB version of the WinTV-quadHD, and didn’t have this specific problem, but getting it to work was difficult.
I needed firmware from here:
palosaari.fi/linux/v4l-dvb/firmware/Si2168/
… and then made the install using the instructions provided on the Hauppauge site. Driver details are:
$ modinfo cx23885 filename: /lib/modules/4.4.0-83201707011420-generic/kernel/drivers/media/pci/cx23885/cx23885.ko license: GPL author: Steven Toth <stoth@linuxtv.org> description: v4l2 driver module for cx23885 based TV cards version: 0.0.4 license: GPL author: Steven Toth <stoth@linuxtv.org> description: Driver for cx23885 based TV cards firmware: v4l-cx23885-enc.fw
The card was found:
$ dmesg | grep -i dvb [ 8.521093] cx23885: CORE cx23885[0]: subsystem: 0070:6a28, board: Hauppauge WinTV-QuadHD-DVB [card=56,autodetected]
The card would be recongnised in Plex DVR but would not find any channels during scan. The “fix” was to put the card in debug mode by adding the following line to /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="cx23885.debug=8"
… which was a solution that came from here:
mail-archive.com/linux-media@vger.kernel.org/msg113541.html

I have the ATSC version, so that may be the difference. Also, for what it is worth, Hauppauage released an updated PPA release based on the 4.4.0.89 kernel and it doesn’t have the issues on my hardware. Yay! :slight_smile:

I did note these pages, which show no firmware needed for the ATSC version, but needed for the DVB version.
