Subject: how to make a2dp device works after chroot?

Hi:
I met a problem about chroot.
After connect the computer with my bluetooth earphone, I can hear the
music from a2dp bluetooth earphone, but when I chroot to /root-A, and
use "aply" command to play some sounds, I can't hear anything from the
earphone.

My question is:
how can I use the a2dp device after chroot?


Thanks

Regards
Bourne

No, now are to looking to the new modes specified by the Core
Specification Addendum: The Enhanced Retransmission mode and the
Streaming mode. I'm working on the implementation of both modes,
helped by Marcel. Enhanced Retransmission and Streaming mode will be
available soon.

Thanks Gustavo. What about "RFCOMM support for sending RLS (receiving works=
)".
Is this feature available?

Have you tried pulseaudio? It should do this for you.

Subject: make all sounds forwards to a2dp device

Hi,
when I connected to a2dp device, I can play music with mplay and
received from my a2dp earphone, but the other application such as
recoder, firefox flash, can not sounds from the earphone, but still
sounds from the speaker on the computer.

so, my question is, can I make the sounds force output to a2dp
device while there is a a2dp bluetooth device connected? and how to do it?

Bourne

Probably this is not related to BlueZ, but to something missing from
your chroot, the following should do the job:

mount -o rbind /dev /root-A/dev
mount -o bind /sys /root-A/sys
mount -t proc none /root-A/proc

(the rbind option and mounting /proc are to be on the safe side)
