Please test and see if things are better or worse. .. 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.
