I have a fresh install of Fedora 21 with this chipset on an Asrock X58
Extreme6 motherboard. There is sound coming out of the speakers, but it is constantly cutting in
and out. When I look in the audio and video settings under KDE, I can
see the Device Configuration Connector constantly switching back and
forth between Headphones and Line Out at a rate of several times per
second. I recorded this in a .gif file and you can view it here: <a id="yui_3_16_0_1_1424455629878_16766" href="http://makeagif.com/V3fT8p">http://makeagif.com/V3fT8p</a><br></div><div id="yui_3_16_0_1_1424455629878_16751"><br></div><div id="yui_3_16_0_1_1424455629878_16937">The system is dual-boot and the audio hardware works fine under
windows. The same thing happens in both gnome and kde. The sound output I want to use is the analog stereo output on the motherboard which uses a Realtek ALC892. I made an audio recording of what it sounds like when I push the audio test button in a .ogg file here: <a id="yui_3_16_0_1_1424455629878_17052" href="https://filetea.me/t1sW6lUC9ABSciAO5zTMvA1nQ">https://filetea.me/t1sW6lUC9ABSciAO5zTMvA1nQ</a><br></div><div id="yui_3_16_0_1_1424455629878_16937"> </div>

Is there a known workaround or solution for this problem? I believe I
once had a similar or related problem on windows with this motherboard
and found it documented in the realtek documentation. I think it was
something about disabling notifications for audio devices being plugged
and unplugged, but I'm not sure. Perhaps it's a jack detection
issue, but what is the best solution for fedora 21? <br></div><div id="yui_3_16_0_1_1424455629878_14936"><br></div><div id="yui_3_16_0_1_1424455629878_14937" dir="ltr">Another thing I tried was downloading the linux drivers from <a style="" class="" id="yui_3_16_0_1_1424455629878_14973" href="http://www.realtek.com.tw/downloads/" target="_blank">http://www.realtek.com.tw/downloads/</a> but they will not compile without errors on fedora 21.
