Robert,
What commands have you had success with, to get sound working? If I use arecord and aplay I get a 2 second lag, so the lip sync is out. If I use
sox I get pitch shifting and other resampling problems (the frame was in the right place but obviously the out wasn't getting the same amount of data
as the in).
Something along the lines of (from memory)
arecord -D hw:1,0 -f S16_LE -c 2 -r 48000 | aplay
I did originally have the problem that the audio was initially in sync,
but very quickly drifted out of sync with the picture I was watching in
xawtv. But last time I tried it this was fine.

P.S. I'm in a position now to try a few things rebooting this machine repeatedly. Where did you find out about cx88xx module options? I'll try a
number of things and see what success I get.
I simply used 'modinfo cx88xx' and guessed at some values.
I've also seen suggested that 'options tuner port2=-1' might help, but
it never seemed to do me any good, and I can't begin to guess at what it
might do so I don't have that set at the minute.

Until I've got that, the tuner doesn't work properly. I also have the
following in my modules.conf:
options cx88xx i2c_scan=1
I'm not sure if it makes any difference of not. But it might be worth a
try.
Great, I tried that and eventually it worked.
I I created a file (cx88) in /etc/modules.d with the options line in it,
rmmoded tuner followed by modprobing it back and nothing,
So I unloaded a load of modules (trying to work back to unload cx88xx, but
not getting that far) and ran this:-
rmmod tuner; sleep 5; modprobe tuner; dmesg |grep tda
And magically after 5 seconds:-
[17201706.416000] tda9887 2-0043: tda988[5/6/7] found @ 0x43 (tuner)
Interesting. I'll have to try that in my startup script. I have that
rmmod && modprobe twice in there, but it still doesn't always work.
Then I managed to run scantv and pick up everything I expected to, great.
Looking back I had unloaded tuner cx88xx cx8802 and cx8800
That rings a bell. I think I usually need to unload cx88_alsa and
cx88_dvb as well.
I'll reboot in a bit and try again without your modules file and see if
that in important or not.
You'll have to report back the results. I know the HVR3000 developer
Steve Toth follows this list. I'm sure I've tried in the past messing
around with module options, but it still seemed random to me whether it
detected the tuner or not.
Robert.
