Hi Andy, Hans, We're still hunting down the audio issues we raised a while back. While we thought we had it beat, we have discovered through testing that over a period of a few days we end up with audio drift (the audio appears to get ahead of a the video slightly). Given this, we're still investigating itwhich is why we haven't reported back.
We are also actively switching between different inputs (Tuner, SVideo, Composite), as well as between NTSC and PAL input sources. We have no yet successfully encoded a PAL signal from a PAL DVD player. Is there any known issue with PAL mode? Does anyone have that working with the latest mainline (1.0.3) driver? A few other observations: The tuner audio does not appear to drift, although I am checking that this weekend (leaving it running for 48 hours straight). Switching from NTSC to PAL format and back for the AV inputs appears to result in an unusualble system and requires a reboot. The transport stream of the tuner feed appears to work properly (no popping audio or issues), whereas the TS of the AV inputs exhibits audio problems. If we apply the changes we shared two weeks ago, the audio problem on the AV inputs goes away but we eventually see the drift where the audio gets ahead of the video. Andy, out of curiosity, is your primary testing againt tuner input or do you often use the AV inputs as well? We are just at the beginning of digging through the data sheet on the cx25840 to start to understand the different pathways and how the AV lock differs between the tuner input and the other inputs and will share any findings or questions. I have a wide range of input types I can test against so if there is anything you want me to try out and report back on, please let me know. -Jeff
