My problem

I do not get any sound from any of my analog connectors. HDMI output from the Radeon card is working fine when i select that in pavucontrol.

All jacks are showing (unplugged) in pavucontrol wether cable is plugged in or not.

This is not a fresh install, but i encounter the same problem when booting from a live disk.

My hardware:

• Asus M5A99FX PRO R2.0
• AMD Radeon 7950

I'm running Xubuntu 16.04.

What i've tried

I've tried (among other things):

• All the obvious stuff (headphones are working, alsamixer is not muted, etc)

• Making sure that audio device is enabled in bios

• Toggling front audio in bios between AC97 & HD

• Installing realtek drivers from their site.

• Adding "options snd-hda-intel model=auto" & other models to /etc/modprobe.d/alsa-base.conf

• https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

• Disabling / enabling loopback & automute in alsamixer

• Using multiple built-in audio profiles in pavucontrol

• Using multiple ports in pavucontrol

• Using one of the latest kernels to get new alsa driver

• Reinstalling alsa & pulseaudio

• Killing the pulse daemon and testing sound with:

  aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav

  speaker-test -c 2 -t wav

• Renaming /etc/modprobe.d/alsa-base.conf to make alsa use defaults

• Disabling jack detection with hdajackretask

• Retasking rear green line out to other options with hdajackretask

• Testing sound output from a fresh windows install (which worked…)

Pulse errors

I noticed something that i think is causing this, but i can't find any relevant solutions on the web.

Pulse is logging thousands of messages like this in debug mode.

Nov  1 17:09:44 synapse pulseaudio[2445]: [alsa-source-ALC892 Analog] alsa-source.c: Overrun!
Nov  1 17:09:46 synapse pulseaudio[2445]: message repeated 10 times: [ [alsa-source-ALC892 Analog] alsa-source.c: Overrun!]

I've been debugging this issue for 2 days now. This is the first problem with ubuntu i have not been able to solve by myself.

Any advice would be appreciated. When you need more information about my system, please ask.
