[SOLVED] Audio stopped working on Macbook Pro

The audio mysteriously stopped working on my Macbook Pro.  Audio doesn't seem to work through the speakers, headphones, or HDMI.  I can, however, see the audio meter moving via pavucontrol when I'm playing sound.  If I boot back into Mac the audio works fine.

I'm currently running the linux-macbook 4.8.16-1 kernel.  The sound worked when I first installed the kernel, so I'd doubt it's the cause.

https://aur.archlinux.org/packages/linux-macbook/

Booting into the stock kernel does not resolve the issue.

Things I've Tried

I added the following entry in /etc/modprobe.d/50-sound.conf but that did not resolve the issue either -

options snd_hda_intel model=intel-mac-auto

I've cleared the local pulseaudio tdb files and restarted pulseaudio, that doesn't resolve the issue

% rm ~/.config/pulse/*.tdb
% systemctl --user restart pulseaudio

I've also performed a full system upgrade via `pacman -Syu` to ensure I hadn't broken any package dependencies.

Debug Info

Here are the outputs of various commands as well as what pavucontrol looks like.

`amixer info ; pactl list` (while not playing sound) https://ptpb.pw/yrMc
`pactl list` (while playing sound) https://ptpb.pw/vbdZ
`amixer contents` https://ptpb.pw/wEpa

The problem as that `asoundconf` had generated some bad configs.  Removing the files ~/.asoundrc and ~/.asoundrc.asoundconf then rebooting resolved the issue.  I also reinstalled pulseaudio-alsa to ensure /etc/asound.conf was in its original state.
