Every time the cx8800 module is loaded I hear annoying high-pitched noise until I open tvtime. After closing tvtime there is no sound anymore. Similar case was already reported here: http://video4linux-list.redhat.narkive.com/I1MD0PsM/cx88-white-noise-with-audio-cable-no-sound-with-cx88-alsa But it is very old case (even pre-F16) and seems that it did not get any attention. I have the TV card connected to soundcard’s Line In as I couldn’t get the cx88-alsa to work. Is that so, if I do not see the corresponding "…[Audio Port]…" in lspci, that my card does not support the DMA sound and cx88-alsa won’t work? At boot cx88-alsa is not loaded at all and if I load it by myself there is no log output apart from "cx2388x alsa driver version 0.0.9 loaded". No new audio device is created or anything like that.
