Is there a way to find out which video codecs etc. tvtime is using so I
can duplicate them in mplayer. tvtime -v doesn't tell me (I think) nor
is mplayer -v helpful.
I have tried the sound with PulseAudio installed and removed. No
P.S. I am starting a new thread because a lot of information has

I did a whole bunch of googling about your problem with the sound, and did
find this on the v4l wiki for DVB. See below for link, etc.
I appreciate the your time and effort. I reviewed the site. Thanks.
The suggestion is to load the following module, which affectively will create
another soundcard for capture from the TV card.
Placed it in /etc/rc.d/rc.local for the time being (modules are a
subject for another day)
For me, that also installed the cx88 module, and another bunch of modules
related to v4l. As I don't have your TV card, or any TV card on this machine,
I suspect the only extra modules you will see in lsmod is cx88, and
cx88-alsa. You may now see 2 cards listed from the following command.
]$ lsmod | grep cx88_alsa
cx88_alsa 20488 0
cx88xx 75048 1 cx88_alsa
videobuf_dma_sg 19972 3 cx88_alsa,cx88xx,cx23885

If by some miracle you do, alsamixer as below should access controls for the
alsamixer -D hw:1 (F4 again, if there are any capture controls)
Alas, no miracle.
The wiki link above suggests setting an alias line for cx88-alsa, and an
options line so that on bootup it's set as card1. Some modules create
problems and try to grab card0, which would create a conflict with your
onboard soundcard which is set to use card0.
There is no /etc/modprobe.conf file in F10, and not being sure where to add
lines in /etc/modprobe.d's files, I simply created a modprobe.conf file
in /etc, so that I could place an options line for my usb midi keyboard, and
it appears to work ok. I would suggest that you might do the same, and add
the following lines to it.
alias snd-card-1 cx88-alsa
options cx88-alsa index=1
No point unless a second sound card has been created.
I am now getting some ticking sounds as if mplayer is trying to produce
sound. I will keep tweaking and fiddling.
