[Bluez-users] A2DPD fails to init with a2dp_make_listen_socket: (errno=13:Permission denied)Cannot bind socket

[TJ]

Hi (Third attempt to reach the list),

While I have got headsetd working fine, but I can't get a2dpd to run.
It gives the following messages:

This is from CVS on 2007-04-17, I did an update today (2007-04-19) but there
doesn't seem to be any changes.

Using libsbc 0.0cvs20070327-1 (Debian testing package)

This is on Debian testing with bluez-utils 3.7-1, linux kernel 2.6.20.

I should say that I installed plugz into my home directory and I run all the
daemons as my user not root. I have PATH, LD_*, etc setup and I created
symlinks in /usr/lib/alsa-lib to the files in the alsa-lib under my home
dir, since I didn't know how else to tell ALSA where to look.


On a more positive note here is an asoundrc to give you a headset volume
control in the alsa mixer:

pcm.!default {
        type softvol
        slave {
                pcm "headset"
        }

        control {
                name "Bluetooth Headset"
                card 0
                count 1
        }
}

Add this to the asoundrc shipped with plugz, you don't have to call
it !default. You can now use any alsa mixer app to control volume (and so
create key bindings). Obviously this means you can disable soft mixer in
xmms and tell it to use "Bluetooth Headset".

Make sure that the control name (here "Bluetooth Headset") doesn't already
exist in your mixer as a real (hw) control.

Thanks for any help.

Thorben.

Hi,
thank you for the softvol trick.
It looks like you already have a2dpd running.
maybe killall a2dpd before could help

No, it's definitely not already running. Its not listed in ps -Af, and I
have even rebooted. headsetd is not running either.

It appears to run OK as root (from my homedir):

Surely it must be possible to run as a normal users? don't the docs say
_not_ to run a2pdp as root. While running as root I can play anything from
my user, only if the playing app is running as root, which is not at all
ideal.

I would assume this is a permissions issue. Obviously my user can write
to /tmp, and headsetd runs fine as my user to bluetooth/alsa comms must be
ok?

So what is causing this?
