3 problems: sound, switch to tv, failure to quit
Hi, I'm using an oct 26 snapshot of the cvs, RH8. I finally got
everything compiled, installed, and now I have a couple of issues to
work out. I'm getting pretty excited, everything looks really slick,
polished and I think the gui is going to be great.

1) sound issues: I'm having some sound sync issues, the sound far
ahead of video problem mentioned in the faq. The faq instructs me to
mute the line in etc etc. Now I have no sound. It occurs to me that in
the myth command line setup routine, the default video device was
called /dev/video, where mine was really /dev/video0 which I discovered
via xawtv. Is it possible that the default sound device is also not
appropriate for me? Would the setup program complain if I had the wrong
sound device chosen? How do I figure out what my device name my sound
card is actually using? ps, the sound card is working for other apps.


2)if I run the command line app mythtv I successfully can watch tv,
pause, ff, rewind etc, all perfectly except for the sound issue
mentioned above. Similarly mythfrontend seems to be working ok too. I
can schedule shows, resolve conflicts etc, but I can't switch to
watching live tv. I've tried it a few times and it either just pretends
that I haven't pushed the live tv button, or once, switched to a
picture of the blue background. No tv in site though. As a side note, I
assume the "setup" button doesn't do anything yet? Not on mine anyway.


3)finally, mythtv and mythfrontend seem to have a bit of a life of
their own. Mythtv takes over the screen, obscuring other apps, and if I
try to select other running apps via the control strip at the bottom,
or perhaps switch to a different virtual desktop, mythtv refuses to
give up. The only way I can quit it is to use a contextual menu on the
mythtv icon in my control strip, the blindly grope (or use a key combo)
for the "close" option, because mythtv obscures any menus I manage to
open. mythfrontend is even worse. It completely hides my desktop (which
is good until I want to quit), doesn't let me select another app, hides
the control strip, and does not respond to the esc key, control-c or
anything else I can think of. I end op having to kill x11 in order to
quit the darn thing.


oh, is there a comprehensive list of key strokes and commands that the
mythapps use that I've missed somewhere?



Great job Isaac! You have a tivo killer on your hands with just a
little more work!

You need line in muted AND your sound card needs to be set to record from
line in. Remember when Mythtv is "playing live tv" it is really recording
live tv and playing back that recording a few seconds later. Most linux
sound drivers default to record from mic so you'll need to change that with
your favorite mixer app.

I've run into a bit of wierdness there too, what happens if you go into
"watch live tv", change to a channel, then go back to the guide? Does it
seem to work right then?

thanks. I do have both the mute and record from line in set. Is there a
way I can concretely determine what device name my sound card is using?

actually I can't do what you suggested. Though I can watch live tv if I
type "mythtv" from the command line I can't watch it at all trying from
the mythfrontend app.



thanks

Did you try hitting the "c" key to change the input being used by mythtv?
By default, I get a green screen and then cycle through, TV, composite in
etc.
