As in the past, I can initialize the card into analog mode after a reboot, and view video feeds from over-the-air analog TV (what little remains anyway), composite video in, and svideo in just fine. Audio for the TV also works fine via the cx88-alsa driver, as usual. However, for some reason, switching to either composite or svideo input does *not* switch the audio input to the two RCA jacks on the harness like it should. Instead, when I switch to composite mode I get the TV audio from the last channel I tuned to, plus a little crackling or static (probably feedback from the VCR I have connected to that input), and plain white noise when I switch to Svideo mode. Just to be sure it wasn't an outdated driver, I cleaned up my kernel configuration, fetched a fresh copy of the v4l-dvb repository, and built/installed it, then rebooted and tried again. Using `xawtv -noxv` for video and sox for the audio stream, as usual for these kinds of tests. I could swear that this used to work some time back, but I can't make even a rough guess as to when it quit working. -- "There are some things in life worth obsessing over.
