Hi,

 

I received a Banana Pi M2+ board on which I installed ARMBian.

Their is only one problem for sound.

Audio out is only available on HDMI.

 

As I will use this board with no display, keyboard and mouse connection how may I get this board playing sound ?

 

Two ways but I do not know which one is possible :

     1) does it exist an HDMI to sound 3.5mm jack adapter ?

    

     2) which USB bluetooth dungle works perfectly on ARMBian I may use to pair this board to a portable bluetooth speaker ?

 

Sincerely thanks.

 

Have a nice day.

It's a known bug ... 

 

One walk around is to use USB sound card until problem is fixed ... Regarding USB BT, no idea what to recommend. Perhaps only avoid latest BT products?

     1) does it exist an HDMI to sound 3.5mm jack adapter ?

    

     2) which USB bluetooth dungle works perfectly on ARMBian I may use to pair this board to a portable bluetooth speaker ?

 

 

1) HDMI VGA converters have a jack output (some, not all have it). Beware to verify that they dont need to much power ! Better by a cheap usb DAC as recommended by IGOR or a good one if you will connect to a good sound system.

 

2) I use Logilink BT0015A (ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle) USB 2.0 Bluetooth 4.0 +EDR Micro Class 1 (6 euros)

 

Bluetooth and "Works perfectly" is a good joke ! But I use it for pan service, with a good range and reliable connection with other nodes with class 1 dongles. It should of course work for a2dp "IF" you get a version of bluez where this has not be broken.

 

Tips :

- on my bpi m2+ I had to disable internal BT in script.bin in order to allow bluetoothd to reference the usb dongle correctly.

- internal BT card may work - but not for me with pan service anyway (bluez bug)

- the bt0015 is a class 1 device (100m) : the range should be a little better than with class 2, but your speaker is certainly class 2, so you will be lucky if you get 5m range.
