# IMPORTANT: READ THIS BEFORE RUNNING THIS SCRIPT!
# This script only works when the system is configured correctly. Do these things first:
#
# Step 1:
# - If you have an ~/.asoundrc file, rename it to ~/.asoundrc-default. If you don't have one, create an empty file named ~/.asoundrc-default.
# - Create ~/.asoundrc-jack with the contents found here: https://gist.github.com/MaartenBaert/3630a1863969ba344704
# The script will create a symlink from .asoundrc to .asoundrc-jack when started, and from .asoundrc to .asoundrc-default when stopped.

Manually fixing bit flips in BTRFS

Somehow my BTRFS file system became corrupted by what appears to be a single bit flip in a metadata field. Rather than copying all the data and reformatting the file system, which would have required another disk at least as large as the original, I decided to try to fix this manually, which appears to have worked. I've documented the procedure I've used here, in case I need it again or someone else runs into a similar issue and finds it useful.

The first thing you should do is run btrfs check. For me this produced the following output:

Opening filesystem to check...
Checking filesystem on /dev/nvme0n1p1
