I had to connect the audio from the tuner card to the sound connector to
get mine to work years ago. All my cards now are atsc only.

Tvtime works fine on 2008.1; I use it pretty much constantly with my
Hauppauge Win-TV HVR-1800 card (which is also a hybrid tuner card). I
even occasionally use both tuners on the card at once, like so:

This screenshot shows tvtime displaying the (analog) NBC News broadcast
and mplayer showing the (digital, HD) ABC News one at the same time.
This capability came in very handy just the other day, when my beloved
Red Sox were playing at the same time as my equally-beloved Patriots
were (hey, what can I say - I'm a native Bostonian). ;-)

The thing to know about tvtime is that aside from allowing you to set
which mixer device (and channel on said device) the program's volume
control will operate, the app doesn't really concern itself with where
the sound comes from, and how it gets to your speakers. It was designed
for setups where the sound is patched from the capture card to the
sound card's line-in input, as those have been the most common types of
TV capture cards available up until fairly recently; another design aim
is to work well as an embedded video viewer app for other programs such
as MythTV, where the calling app is expected to handle the audio and
tvtime's responsibilities are therefore limited to video display only.

Should you happen to be using the same model of card as I am, and/or
for the benefit of anyone else trying to get the HVR-1800's analog side
working on MDV 2008.1, a couple of tips:

1) You need to be using a kernel from at least the 2.6.25 series, as
the 2.6.24-x ones supplied in the standard MDV repos do not provide
sufficiently advanced drivers to create the /dev/video device. I use
the "kernel-linus-smp-latest" RPM (which currently gets you 2.6.25-16);
it's available from the Contrib Updates MDV repositories. If you run a
single-core-CPU box, get "kernel-linus-latest" instead.

2) Support for the HVR-1800's onboard MPEG2 encoder, and therefore for
the audio from either the card's analog tuner or from its onboard audio
line inputs, isn't available until the 2.6.26 series of kernels. I use
the composite video input on the card, cabled from the composite output
on my cable box, and have the corresponding audio outs on the cable box
wired to the line-in input on my sound card. I've tried the 2.6.26-2
kernel available from Contrib Backports, and can verify that it creates
both a /dev/video0 and a /dev/video1 node, so the latter one probably
includes audio (but won't work with tvtime, which expects raw video,
not MPEG2); however, despite the fact that I have the right -devel RPM
installed for that kernel, dkms refuses to build working modules for
the three modules that it has no problems building for every other
kernel I've used on here, and since one of them is my NVidia driver, I
haven't been able to test the .26 kernel with X11. I figure I'll just
wait for 2009.0 to be released before monkeying with this again. :-/

HTH!

Your card has two tuners. Most marketing departments would call
that a dual tuner card. Mine has only a single tuner, which I
did not realize until after I had bought it.

Does all of this mean that tvtime can't get the audio over the PCI
bus without a helper application? I have plugged in an extra
audio cable from the tuner card to the motherboard and now have
sound with tvtime. (Kaffeine does not need this extra connection.)

Cooker has 2.6.26-3 series kernels.

That's exactly what it means. It can adjust the volume on a mixer
channel that you specify, but something else (a helper app, a separate
kernel module, or both) must actually make the audio signal available
on that mixer channel. Your patch cord accomplishes this manually, and
no doubt one of the mixer channels of your onboard sound chipset now
carries TV sound; tvtime can be configured to adjust the volume on that
with "+" and "-", once you tell it which mixer and channel it's on.

Kaffeine doesn't need that because it uses the digital side of the
tuner, while tvtime uses the analog side; the digital side presents to
the system as a dvb device, while the analog side presents as a v4l
device. Different interfaces entirely, with differing capabilities.

It works the same way in Windows so no, this is not a bug.
You need to connect the sound card to the audio output of the tuner card
with wire.
