noise after modprobe cx8800

noise after modprobe cx8800

[Paweł Kiełkowski]

Hello,

I have also another issue after switching from Fedora 16 to Fedora 22.
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.

Fedora 16 kernel: 3.6.11-4.fc16.i686.PAE
Fedora 22 kernel: 4.1.6-200.fc22.x86_64
TV card: 01:09.0 Multimedia video controller [0400]: Conexant Systems,

Line In is not muted in Fedora 16. I use following options:
