About

This gist will show how to setup a generic SBC Debian / Ubuntu install as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

This is forked from another gist specific to the Raspberry Pi on Stretch. A required package isn't in Ubuntu's repos, so in this gist we build it from scratch.

Tested to be working on Armbian/Ubuntu/Debian images of the Orange Pi Zero, ODROID XU4, ODROID N2, and Atomic Pi.

Zoom U-44 PulseAudio Setup

Problem Statement

The Zoom U-44 works out of the box with recent Linux versions.

By default, PulseAudio will register it as a single sink with 4 output channels. As the U-44 is organized to have two stereo pairs for outputs, there are situations where it is more useful to have 2 separate sinks available, each playing back to one of the two stereo pairs.

Recovering deleted files in Ubuntu with ext4 filesystem

Recently, I deleted some files by mistake in a Ubuntu machine with an ext4 fs. These notes document the steps I took to get them back.

Important

• this procedure assumes that the partition that contained the deleted files is different from the root partition, as that was the scenario with which I had to deal (deleted files were in my home dir). The procedure needs that the partition that contained the files is unmounted, so if the deleted files were in the root partition, the process would be a bit different (e.g. storing the fs journal in a USB stick, using a live CD/USB to boot and issue the commands, etc.)
• if something is not clear, you need more information, etc. check the sources below

With that out the way, let's begin.

Note for newcomers:

In the shortcuts below, "C" stands for CTRL and "A" stands for "ALT". This is a convention
used in the Midnight Commander documentation and was kept here.

You can also use "ESC" instead of "ALT", which is useful on Macbooks.
