Hi,

 

Board: imx6ULEVK

RF: Murata 1DX combo 

Kernel: 3.14.52-1.1.1

BlueZ: v5.28

 

I want to stream music from board to an external bluetooth speaker (Sony SRS-BTM8). I was able to pair and connect with the speaker using bluetoothctl. I used pulseaudio to attempt a stream but failed. I noticed something which I haven't been able to resolve. When I do a "pactl list sinks short", I got the below:

 

0 alsa_output.platform-sound.14.analog-stereo module-alsa-card.c s16le 2ch 48000Hz SUSPENDED
1 bluez_sink.8C_DE_52_1E_3C_F9 module-bluez5-device.c s16le 1ch 8000Hz SUSPENDED

 

The BIG question is why did my speaker appear as a "1ch 8000Hz" device? I was expecting the description to be something like "2ch 44100Hz".

 

I believed this was the main reason why I failed to stream. 

 

Does it got to do with the fact that my bluetooth speaker also support handsfree? Any advice here? 

 

Regards,

BT
