INTEL EDISON AUDIO LOOPBACK HOW TO

You can also build mpg123 to play mp3 files, I might document how to do this later. I canвЂ™t figure how to add attachments to wordpress but at the bottom of the post copy the contents of вЂњalsa-plugins_1.0.28.bbвЂќ to a file. So this means the capturing of this audio stream has to be done via /dev/snd/pcmC2D1c if you select loopback as the input device for flash, it will use /dev/snd/pcmC2D0c instead ( plugin-co means the plugin container flash is running in): userdesk: lsof grep /dev/snd/pcmC2 pulseaudi 3314 user mem CHR 116,13 556 /dev/snd/pcmC2D0p pulseaudi. If you havenвЂ™t done this itвЂ™s pretty straight forward given an Ubuntu desktop (my machine still has Ubuntu 12.04) and with an SSD and an oldish i7 the initial build takes an hour вЂ“ incremental builds are far quicker. These instructions assume youвЂ™ve already done a build according to IntelвЂ™s BSP Guide for Edison ( ). Instructions are based on the following Edison source/recipe and images IвЂ™m sure the pulseaudio configuration can be cleaned up for example.

Take these instructions with a pinch of salt, IвЂ™m not a Bluetooth / pulseaudio or bitbake expert.

Pair and connect to a Bluetooth audio speaker via A2DP.

Show how to start pulseaudio and hook it up with Bluetooth.

Show how to build the ALSA plugin library to use aplay.

Get you the bluez5 modules that pulseaudio needs.

The gstreamer plugin in the edison release I used is very out of date, and even after getting the latest recipe from yocto and hacking it to configure it for bluez5 I just hit a SIGSEGV in gstreamer. IвЂ™d originally hoped to get the Gstreamer a2dp plugin working, however, this proved a dead-end. This makes life hard because Bluez 5 had introduced various incompatibilities which make Bluez 4 oriented instructions incorrect for Bluez 5 вЂ“ be careful of this when searching for any bluetooth audio guides. There doesnвЂ™t seem to be any consolidated effort to make migration from Bluez 4 to 5 easy for non-experts (like me). The user documentation for Bluez 5 and integration (or lack thereof) with pulseaudio, gstreamer and ALSA is sporadic and inconsistent. If blame was reasonably apportioned the problems surround Bluez 5 (and my own lack of knowledge of course!)

Unfortunately, I ran into problems with the stock image (edison-image-rel1-maint-rel1-ww42-14.zip) available at the time of writing and didnвЂ™t find enough help even in the very useful repository provided here ( ).

Skip the next few paragraphs if you donвЂ™t care about the background of the problems I had. The Edison compute module has integrated Bluetooth so it should be easy right?

INTEL EDISON AUDIO LOOPBACK PORTABLE

I wanted to use a portable bluetooth speaker with IntelвЂ™s edison board to playback audio files. Edit: IвЂ™ve cleaned up some parts of this post, I also posted about this in the Edison community forums:
