Dug a little deeper,
Changing the one line in the cx25840-driver.c fixed it. Not a
permanent solution, but should help in issolating.
Looks like cardtype is NEVER set in the driver itself. You moved it to
the cx25840_command subroutine, but
it is never called, at least not I can see.
I changed line 59 to specify a default of cardtype=1. It worked??
static int cardtype = 1;
So, I think all the mods we made based on "cardtype", are not called as
cardtype stays 0.

Hans,
I have the Diamond PVR-550 card, and we worked together on the
0.3.7g release, and finally got a
patch that worked. Problem was cardtype=1 gave video only, until we
patched, then sound came with it.
I tested 0.3.7k and it failed miserably. No audio or video on the
Tuner input (1).
I tested 0.3.7k with your patch... still fails...
Just like 0.3.7i that I reported, and you thought it was due to me
specifying a cardtype on the modprobe.conf.
It appears the module does just ignore this option, and still loads
by the way, I tried without it, and
it still fails. No video or audio. But, in 0.3.7i, I know Composite
and Svideo worked, just no Tuner input.
Since a patched 0.3.7g worked, I stepped up in revisions to see
where it broke.
Well, the very next release, 0.3.7h, I install without any patches,
and removed the cardtype def in modprobe.conf.
This should have, as in the previous release, given me video, without
sound.
Instead this gives nothing. No sound and No video.
So something significant changed in this release, and probably in
the auto-detection algorithms you put in...
Maybe we turned something on inadvertently....?
I don't have time to dig deeper right now, but the Tuner input of
the card seem to have stopped working as of 0.3.7h.
Hopefully that gives some clues..

It solves a problem with missing sound when using the tuner. However,
I am
not sure if this patch might break the sound for others who now have
good
sound. Please let me know if it succeeds or not!
Without feedback during the next week I'll just put the patch in and
hope
for the best.
