+ Enabling LE Audio/LC3 in WF-1000XM5
+ https://github.com/thiagokokada/blog/blob/main/posts/2024-10-07/01-enabling-le-audio-lc3-in-wf-1000xm5.md
+ <p>One of things that I hate the most about the fact that we are all using
wireless earbuds instead of wired earphones is the latency: it is bad, getting
up to seconds(!) depending on your particular combination of OS/earbuds/device.</p>
<p>There is a solution though: Bluetooth LE Audio, that is supposed to fix
multiple issues with the original design for Bluetooth Classic Audio, including
a much lower latency, improved efficiency (e.g.: less battery power) and even
multiple streams of audio. LE Audio also includes a new default codec for
improved audio quality, <a href="https://en.wikipedia.org/wiki/LC3_(codec)">LC3</a>, that
replaces the venerable <a href="https://en.wikipedia.org/wiki/SBC_(codec)">SBC</a> codec
for audio.</p>
<p>However, the standard is a mess right now: a few wireless headphones already
support it, but they're generally disabled by default and it is pretty messy to
enable. And even after enabling it, getting it to work can be a pain.</p>
<p>I have pretty much the best setup to use LE Audio right now: a recently
released Pixel 9 Pro with Sony's
<a href="https://www.sony.ie/headphones/products/wf-1000xm5">WF-1000XM5</a> earbuds, and
after lots of tries I got it to work. You can see below the versions of
everything I am using:</p>
<ul>
<li>Android: 14</li>
<li><a href="https://play.google.com/store/apps/details?id=com.sony.songpal.mdr">Sound
Connect</a>:
11.0.1</li>
<li>WM-1000XM5: 4.0.2</li>
</ul>
<p>The first thing you need to do is enable in "Sound Connect" app "LE Audio
Priority" in "Device Settings -> System":</p>
<p><a href="https://github.com/thiagokokada/blog/raw/main/posts/2024-10-07/photo_4909454744305642922_y.jpg"><img src="https://github.com/thiagokokada/blog/raw/main/posts/2024-10-07/photo_4909454744305642922_y.jpg" alt="LE Audio option inside Sound
Connect"></a></p>
<p>After this, you will need to pair your headset with the device again. You can
do this as same as always: press and hold the button in case for a few seconds
until a blue light starts to blink. However, this is where things starts to get
janky: I couldn't get the headset to pair with Android again.</p>
<p>A few of the things that I needed to do (in no specific order):</p>
<ul>
<li>Remove the previous paired headset</li>
<li>Restart the Android</li>
<li>Clean-up "Sound Connect" storage (Long press the app icon -> "App info" ->
"Storage and Cache" -> "Clear storage")</li>
</ul>
<p>If you can get the headset to connect, go to the "Bluetooth" settings in
Android, click in the gear icon for the headset and enable "LE Audio" option:</p>
<p><a href="/posts/2024-10-07/photo_4909454744305642937_y"><img src="https://github.com/thiagokokada/blog/raw/main/posts/2024-10-07/photo_4909454744305642937_y.jpg" alt="LE Audio option Bluetooth
Settings"></a></p>
<p>If you can't, you may want to <a href="https://helpguide.sony.net/mdr/2963/v1/en/contents/TP1000783925.html">restore the headset to factory
settings</a>
and try again from the start (that means pairing your device with "Sound
Connect" again, and you may want to try to clear the storage before doing so).</p>
<p>Yes, the process is extremely janky, but I think this is why both "Sound
Connect" and Android marks this feature as beta/experimental. And I still need
to test the latency, but from my initial testing there are some glitches when
the audio is only used for a short period of time (e.g.: Duolingo only enables
the audio when the character is speaking). So I only recommend this if you want
to test how LE Audio will behave, since it is clear that this needs more
polish.</p>
