Mmm.. something is not right -- the audio is failing constantly with that change.
Perhaps if I could dump out the registers, we might see what is wrong.
I also tried:
v4l2-dbg -d /dev/video1 -c type=host,chip=1 --list-registers=min=0x800,max=0x9ff
but that fails to read any of the registers (ioctl: VIDIOC_DBG_G_REGISTER failed for 0xXXX).
I think I'll patch the driver to dump them for us.
Thank-you for your work on this. There are many of us here hoping
that we can figure out and fix whatever is wrong with our cards.
Cheers
