[mythtv-users] ConvertX stopped working after upgrading to 0.24

[Naoyuki Tai]

There is a bit of progress.
After reading some source code, by having "tunechan", it can cause Myth to
try to tune the device with external channel setting.

  mythtv/libs/libmythtv/v4lchannel.cpp, line 499

     // If a tuneToChannel is set make sure we're still on it
     if (!(*it)->tuneToChannel.isEmpty() && (*it)->tuneToChannel != 
"Undefined")
         TuneTo((*it)->tuneToChannel, 0);

     // Tune to proper frequency
     if ((*it)->externalChanger.isEmpty())


If you have a "tuneToChannel" value, regardless of it is externalChanger 
or not,
it tries to tune to the channel. Since ConvertX I have does not have the 
tuner,
it fails. I suspect that failing to tune may be preventing subsequent 
recording.
I'd say this is a minor but certainly a bug.

So, seeing the "Tune" can be a red herring. I set the "tunechan" to NULL 
in the
cardinput table and I get passed that. I can capture with some video.

However, I'm not getting audio. I know it could be input level being too 
low.
I'm looking for a way to see how I can see and set the audio.
