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.

Regards,

                Hans
