Hi,
I'm trying to diagnose a problem with a mythtv setup based upon a
hauppauge nova td 500. I've had the setup for some months - it seemed to
work reasonably reliably initially, but over the last few weeks I've had
consistent problems with the tuner card entering a state where it is
unable to receive a signal. I was seeing multiple errors via dmesg of
the form:
[27317.617958] DiB0070 I2C write failed
Web trawling suggested that this could be resolved with an updated
driver - I did this yesterday, with the latest version from mercurial,
obtained and built as per the instructions here:
http://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers
I installed this over the top of the 2.6.27-14-generic kernel from the
mythbuntu distribution, and manually installed the 1.20 firmware.
In 24 uptime hours I haven't seen any I2C errors, but unfortunately, it
has still entered some state where I can't received a signal.
Mysteriously, there doesn't appear to be any relevant errors or messages
in dmesg. From the log snippet below, you can see that no signal is
being returned by tzap, but if I unload and reload the modules,
everything comes back to life.
I'd really appreciate any tips or pointers on what might be going wrong
here.
Thanks,
Tim
