The versions before the VCO center frequency patch do not show this issue. I was mislead earlier (into thinking all the versions had the dropouts) as I was just doing an unload and load to move across versions - this does not seem to be clean, the register writes may not be completely reset. If I do a cold boot in between, then with pre-VCO version I am able to see that there are no dropouts. I also checked the patches you submitted to the staging repository and there seem to be no dropouts with this too. Hi Andy, Thanks. Yes, the VCO change was not needed for me to use my card. About the audio, it is not too bad, but it could be made much better if the gain in WM8739 is increased. Currently it does not seem to be using the full scale range of the ADC, and besides, there is attenuation on the board too, so the final output is pretty low. Increasing the WM8739 volume should help to boost the SNR a lot. I can experiment with the settings once you add the WM8739 support. The other issue I am seeing is the Composite input quality which I mentioned sometime back. There are jagged edges in red/yellow and sometimes white edges. Moving text is very jagged too. I think it may have something to do with the internal de-interlacing in the card, but I have no clue. I plan to try some register settings tomorrow. The S-Video input does not seem to have this problem and gives crystal clear picture. Regards Ravi |
