METEORSINPUT sets the audio channel as well. I never noticed that before. it strikes me as curious behaviour, since METEORSINPUT is for setting the video source, and there is a separate ioctl for setting the audio source. maybe I do want to continue with audio from the tuner and switch to audio from the RCA input without a break in the audio ... -- <jakemsr@jakemsr.com>
