vektor:
oops... stupid me...

now I take another look, the problem is that I incorrectly
assume that the snapshot/bttv tarball already contains the
v4l code, but in fact it doesn't. 
 
So I guess the solution is to patch the kernel in addition
to the video4linux snapshot.

djaara: 
Please forget about changing VIDIOC_S_CTRL. If you have not
apply the kernel patches like I did, try it.

leeal: What driver is this from?

>From what I remember, the entry for S_CTRL changed, but Gerd
Knorr also added a compatibility thing in the driver to
handle programs that are linked.  The kernel API cannot
change once it is released.

Can you find out what version of the kernel made this
change, or what drivers may be broken?

vektor: I think djaara is the original poster.

anyways, I had a similar problem (no sound when using v4l2)
and the cause seems to be that some macros in videodev2.h
(in the driver) has changed and does not match the one in
tvtime's version of the include file.
i.e.,
  in tvtime's videodev2.h:
  #define VIDIOC_S_CTRL       _IOW  ('V', 28, struct
v4l2_control)

  in current v4l2's videodev2.h:
  #define VIDIOC_S_CTRL       _IOWR ('V', 28, struct
v4l2_control)

In my case, I got sound again after I change this macro so
that the one in tvtime matches the one in the driver.

leeal: Where is that source code change from ???  What's
going on here?

If you can't mute your card I bet there is a bug in the
driver.  I won't be able to look into this until next month
though. :(

Try edit src/videodev2.h and change VIDIOC_S_CTRL from:
   #define VIDIOC_S_CTRL       _IOW  ('V', 28, struct
v4l2_control)
to:
   #define VIDIOC_S_CTRL       _IOWR ('V', 28, struct
v4l2_control)
