Below is the detail of my software SDK:
Kernel version : 3.10.17
Build tool : Yocto
Processor : i.MX6 Sololite
Pulseaudio version : 5.0
Bluez version : 4.101
I want to play music from my phone to the linux box running the above
described setup.
When i play song from the mobile, I am seeing the ACL data through
hcidump. but it is not playing on the headphone.
In the pulseaudio logs, i am seeing the errors.
Below are my changes, for pulseaudio and bluetooth.
/etc/pulse/daemon.conf
resample-method = trivial
enable-remixing = no
enable-lfe-remixing = no
default-sample-format = s16le
default-sample-rate = 48000
alternate-sample-rate = 24000
default-sample-channels = 2
/etc/pulse/system.pa
.ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy
.endif
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif
Below are my steps to connect to mobile.
pulseaudio --system --realtime -vvvvv --log-time=1 --log-target=file:pulse.log &
ADAPTER=`dbus-send --print-reply --system --dest=org.bluez /

in, "pactl modules list short"
I am seeing,

this is the logs, i am getting.
