I haven't seen any similar reports in the archives, but my Hauppauge
HVR1600 does not produce usable output with mplayer or VLC in Ubuntu
Linux (9.04 beta/2.6.28-11 amd64) until after I have used the card in a
Windows XP session with Hauppague's WinTV software.
Booting straight to Linux from a power off state results in a black
screen and no audio from both players. ivti-tune and v4l2-ctl
set--frequency both produce normal output and indicate the card has been
set to the proper channel/frequency (3/61.125)
DMSG and the kernel logs appear to be nominal. I don't see any obvious
errors.
lsmod indicates all of the required modules are loaded.
The only anomaly I see is that v4l2-ctl --all indicates signal strength
is 0, which is consistent with what I see from mplayer.
If I command a system restart and boot into Windows XP, or boot directly
into XP from a power off condition, the card works fine with the
Hauppauge WinTV software. After I do that, I can command a system
restart and boot into Linux and the card then works as expected.
v4l2-ctl --all indicates signal strength of 100%.
It seems that Ubuntu isn't initializing something on startup, but once
whatever it is gets set it persists through a warm reboot.
I'm really trying to avoid XP as much as possible and would appreciate
any suggestions on how I might make the card work when I boot straight
to Ubuntu.
As a follow-up I've determined that the sequence of commands:
sudo modprobe -r cx18
sudo modprobe cx18
will enable the card, after which it will perform normally until the
machine is powered off. Should this be necessary?
