HARDWARE HVR 1100

From Gentoo Linux Wiki

[edit] Introduction

The Hauppauge WinTV HVR 1100 is a hybrid tuner card with DVB-T and analog tuner. It also has radio support and a remote.

Hauppauge ships two different types of hardware both labelled HVR 1100: One is based on the Conexant chipset, the other uses a Philips SAA7133/7135 chipset. However, both types of cards work fine with Linux.

This page only documents how to get a Conexant CX88 based HVR 1100 running. If you bought a HVR 1100 and running lspci gives you something like

 00:0d.0 Multimedia controller: Philips Semiconductors SAA7133/SAA7135 
         Video Broadcast Decoder (rev d1)

you should now go to the HOWTO Page for the SAA7134 driver. Additionally, you can take a look at this discussion on the Gentoo forums.

[edit] Conexant CX88 based HVR 1100 cards

I can't get the radio support to work. It appears it's not ready. The kernel diver file says : /* FIXME, add radio support */ But it seems it's coming.

BTW, for those of you having a dual boot system, the card does not work well at all on Windows.

[edit] What you need to make it work

- Kernel >= 2.6.16, - Lirc (optional), - A xine-based or mplayer-based video player.

[edit] Kernel configuration

In the kernel, you have to enable the following options :

CONFIG_DVB=y
CONFIG_DVB_CORE=y
CONFIG_DVB_CX22700=m
CONFIG_DVB_CX22702=y
CONFIG_VIDEO_CX88_VP3054=m
CONFIG_VIDEO_CX88=m
CONFIG_VIDEO_CX88_ALSA=m
CONFIG_VIDEO_CX88_DVB=m
CONFIG_VIDEO_CX88_DVB_ALL_FRONTENDS=y

This sample is from kernel 2.6.17-rc1

IMPORTANT : As you might have noticed, some of the drivers are compiled as modules. They HAVE TO BE compiled as modules. Compiling them in will NOT work

[edit] Alsa module configuration

This particular card uses the PCI interface to broadcast its sound. The Conexant chip that is on it is considered by alsa to be a soundcard (a very simple one!). So, as you might expect, if you have specified snd_card_limit=1, things will break.

You need to edit /etc/modules.d/alsa

snd_card_limit=2

You can now reboot to your new kernel with dvb support.

[edit] What you should have now

If you have coldplug installed, the modules have been loaded automatically at boot, otherwise, you have to ad them to /etc/modules.autoload.d/kernel-2.6.

So, lsmod should show :

cx88_dvb               11548  1
cx8802                  9732  1 cx88_dvb

btcx_risc               4232  4 cx8802,cx88_alsa,cx8800,cx88xx

Your /dev should show two different kind of entries :

/dev/v4l, which is used for analog, should show :

crw-rw----  1 root video 81,  64 avr 24 23:57 radio0
crw-rw----  1 root video 81, 224 avr 24 23:57 vbi0
crw-rw----  1 root video 81,   0 avr 24 23:57 video0

/dev/dvb/adapter0, which is used for DVB-T, should show :

crw-rw---- 1 root video 212, 4 avr 24 23:57 demux0
crw-rw---- 1 root video 212, 5 avr 24 23:57 dvr0
crw-rw---- 1 root video 212, 3 avr 24 23:57 frontend0
crw-rw---- 1 root video 212, 7 avr 24 23:57 net0

[edit] DVB Software configuration

The card should now work. If you are using kaffeine, make sure it is compiled with the 'dvb' useflag. Launch it, it should take care of the rest. If not, you will need to use dvbscan.

dvbscan /usr/share/dvb/dvb-t/[YOURCITY] > channels.conf

To use this, you have to copy it over to the config dir of the app you are using. For mplayer do :

cp channels.conf ~/.mplayer/

The card should now be up and running. To access a specific channel :

mplayer dvb://[NAME OF THE CHANNEL]
kaffeine : dvb://[NAME OF THE CHANNEL]

[edit] Emerge lirc

Contrary to what one might think, one cannot use the hauppauge or hauppauge_dvb driver. You have to use devinput You have to add a variable to make.conf :

echo 'LIRC_OPTS="--with-driver=devinput"' >> /etc/make.conf
emerge lirc

I may be wrong, but I think it's changed since lirc 0.8 and the entry should now be

echo 'LIRC_DEVICES="devinput"' >> /etc/make.conf

<kerneloftruth>: (confirmed)

when

     echo 'LIRC_OPTS="--with-driver=devinput"' >> /etc/make.conf

is used with lirc 0.8 you get the following message:

 LIRC_OPTS is deprecated from lirc-0.8.0-r1 on.
  *
  * Please use LIRC_DEVICES from now on.
  * e.g. LIRC_DEVICES="serial sir"
  * 
  * Flags are now set per use-flags.
  * e.g. transmitter, hardware-carrier
  * These options are no longer allowed to be set
  * with LIRC_OPTS:  --with-driver=devinput

so add the line:

LIRC_DEVICES=

and add the device to your liking

EDIT: It's very important not to set any other LIRC_DEVICES than "devinput", otherwise lirc will not recognize your rc!

[edit] Lirc configuration

[see discussion page for possibly changes regarding the linux input layer and inpultlircd]

You do not need to insmod any kernel module

You will not find any /dev/lircX or /dev/lirc/X node in your /dev. The node is in /dev/input. It's one of the eventX nodes. You just have to figure out which ! To figure this out, do :

cat /dev/input/eventX

Then press buttons on your remote, if some code appears, that's the device. If not, try another one.

Then, over to /etc/conf.d/lircd :

LIRCD_OPTS="-d /dev/input/eventX"

Where X is, of course, the number of the event node you found.

EDIT: You may want to use a udev rule to link your /dev/input/eventX to to e.g. /dev/input/irremote to keep you out of trouble since the /dev/input/eventX could change from boot to boot!

# HVR remote
KERNEL=="event*",ATTRS{name}=="HVR 1110",SYMLINK="input/irremote"

It may also be necessary to change

LIRCD_OPTS="-H dev/input -d /dev/input/eventX"

to get your remote recognized correctly! (use either /dev/input/eventX or /dev/input/irremote if you use udev rules)

EDIT END

This particular remote does not have any config file ready in lirc, you have to generate one yourself or copy mine.

To generate one yourself :

irrecord -d /dev/input/eventX HVR-1100

This will create a config file that you need to copy/paste in /etc/lircd.conf :

cat HVR-1100 >> /etc/lircd.conf

As for my config file, here it is :

[edit] Analog TV

Well, that does not work very well. The problem is that the sound goes through the PCI bus, which is not something Analog TV apps are used to. Here is a very cumbersome workaround, that I found on Da Desintegr Blog (see credits). In fact, you have to reroute the signal to your soundcard :

arecord -D hw:1,0 -c 2 -r 48000 -f S16_LE -t wav | aplay -

You have to execute this in a terminal. You have to re-execute the command every time you switch channel. I am currently trying to find a solution by lookink at .asoundrc dmix and dsnoop. I'll let you know a soon as I find something useful.

Write it in a loop (untested, but should work):

#!/bin/sh
while true
do
  arecord -D hw:1,0 -c 2 -r 48000 -f S16_LE -t wav | aplay -
done
