I recently bought some upgrades for my computer and after doing a fresh install of F17 I've had sound issue after sound issue. I am using
this motherboard (quite literally the exact mobo) with the onboard realtek ALC892 chipset.
Sound output semi-works; it seems to break randomly and for no apparent reason that I can discern. I thought at first that it would break when multiple applications tried to output sound, but it has also broken when *nothing* was outputting sound. When I say break the speakers still output a sound, but it's a undiscernible and high-ptiched mess of squeals and static. Generally a quick logout and login will return sound to normal once again.
A second problem I am having with sound output is that when it is working correctly it doesn't seem to be outputting through the proper speakers. I am using a 5.1 speaker system (and have the sound settings set up as such), but when doing the speaker test it does the following:
Speaker Test / Actual Sound output:
Front Left / Center
Front Right / Front Right
Center / Front Left
Rear Left / Center
Rear Right / Center
Subwoofer / no output
Finally I am having problems with sound input as well. The mic I am using plugs in directly to the motherboard/chipset, but it seems to either not be detected or the static is so loud that it drowns out the sound being recorded. All it records is just a steady stream of static with random feedback squeals every so often.
-----------------------
I played around with alsamixer, the system sound settings, and installed the pulseaudio volume control and tried playing around with that as well. Nothing, thus far, seems to have fixed the issue. Numerous google searches hasn't found any results either (TBH most of the results were pretty out-dated as well). I've spent at least 4-5 hours trying to figure this out with no success. I've tried Fedora several times now and I've loved it, but sound problems always drives me back to another distro. If there are any logs or the like that I can supply please tell me. I *really* want to figure these issues out.

Just discovered that when the sound 'breaks' the feedback/squeals persist despite my speaker volume being turned off (turn up/down the volume has no control over it though).
Here are the result of some commands:
aplay -l
