Subject: noise after modprobe cx8800
Date: Sat, 05 Sep 2015 13:28:12 +0200 [thread overview]
Message-ID: <55EAD1CC.1090303@gmail.com> (raw)
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
