a2dp to stereo speakers

[ygator]

One of the bt dongles was recognized on an ubuntu install and I was able to play music to the speakers fine.
So that says the hardware can do it, but there is software and/or configuration issue.

Okay I think I have got this solved. I bet you have a custom kernel that has Bluetooth SCO compiled into it.

I was adding Minix FS support to my custom kernel and thought I would look at what Bluetooth options there were.
Sure enough there was Bluetooth SCO not compiled in.

Do you know if there are any other options you added to your kernel?

My kernel is a bit rare, trimslice custom.
What is yours and what is your plug? Standard kernel26? which is based mainly on https://raw.github.com/archlinuxarm/PKGBUILDs/master/core/kernel26/2.6.39.config

[ygator]

I am on a dockstar and normally use the standard kernel.
However, I have a dockstar I use wireless on and the usb adapter I have is n, but the driver disallows it from doing n.
So I made the patch below. I am now going to recompile a new kernel with this patch, plus minix fs and bt sco support and give that a try.

I am trying to setup an easy way to build a kernel.
I made a shell script to get the kernel files
$this->bbcode_second_pass_code('', '#!/bin/bash
LOC=https://github.com/archlinuxarm/PKGBUILDs/raw/master/core/kernel26/
for f in 2.6.39.config PKGBUILD archlinuxarm.patch kernel26.install kernel26.preset
do
wget ${LOC}$f
done
')

I've added my patch to the PKGBUILD and then did a makepkg --asroot -As
I used to run it with -Acs, but that wipe everything out after it was done.
This works, but I want to leave everything out so it does not take another 4 hours to rebuild.
Does anyone know the command to rebuild and package it up without it trying to reapply the patches and everything else?

You could ask for this to be added in next kernel
This would be easier for me
$this->bbcode_second_pass_code('', 'pacman -S git
git clone https://github.com/archlinuxarm/PKGBUILDs.git
cd PKGBUILDs/core/kernel26')
Un comment make menuconfig, and add your patch and stuff

4 hours, have you considered screen? Anyway, this creates the entire package, Inc your patch and extra modules, no need to fiddle with anything

Getting closer...

Here is what I am now getting when I plug in my bt dongle. This is just after a reboot and I have not start dbus or bluetooth.

Success. I went and re-paired the devices and now it is working (at least with the speakers). I did do some other changes, but it may have just been the re-pairing that did it. At some point I will do a fresh install and make sure.

I am also able to play mp3 files with: mplayer -ao alsa:device=btspeakers music.mp3

[pepedog]

Great.
If you hack the /etc/asound.conf you won't need -ao alsa:device=btspeakers

[ygator]

Hack it how?

I also have never gotten speak to work out a sound device either, but I can make the output of espeak go to a wav file and then play the wav file.
