Testing the setup

Cable TV

Tested with Ziggo Cable Television (Location Leiden) as input which uses this frequenties. As FM Antenna I used a Old S-Video Cable.

$ sudo apt-get install tvtime scantv
$ sudo tvtime-scanner
$ sudo scantv -C /dev/vbi0 -n PAL -f europe-west -o results.ini
$ head -20 results.txt
rvdzwet@sky:~$ head -15 results.ini 
[global]
freqtab = europe-west

[defaults]
input = Television
norm = PAL

[Nederland 1]
channel = 22

[Nederland 2]
channel = 25

[Nederland 3]
channel = 26

FM Radio (The Netherlands)

My antenna is not very good so I had to allow low-quality radio signals (-t 30)

$ sudo apt-get install fmtools
$ sudo fmscan -t 30

Experiences

Both tvtime and XavTV shows me perfect/clear moving images. To setup sound I had to enable a pulseaudio loopback device as instructed at ubuntuforums.org.

The tuner on the radio seems a bit slow takes like 2 seconds to get to the right channel, but works perfectly.

$ fm -T forever 102.7

The IR get detected at /dev/input/event5, but I cannot test it as I cannot find the remote.

Misc

Q: if feasible "eeprom" output (from bttv tools)
A: I am not sure how-to retrieve this information. The bttv tools does not seems to apply to this chipset. But just [info@rickvanderzwet.nl let me know] and I be happy to retrieve it.

Q: How to get it configured under Ubuntu 10.10
A: Make sure to set the modprobe options right and the pulseaudio config

$ echo 'options saa7134 card=63 tuner=43' | sudo tee /etc/modprobe.d/saa7134-tuner.conf
$ CARDID=`lspci | awk '/SAA/ {print $1}' | tr ':' '_' `; 
$ SOURCE=`pactl list | awk '/Name: alsa_input/ {print $2}' | grep $CARDID`
$ echo "load-module module-loopback source=$SOURCE" | sudo tee -a /etc/pulse/default.pa
