Hi all.
I am using WL1831 bluetooth module on a custom board, whose main processor has to send audio to heasets through bluetooth. The board I am working on has just UART connection, since the main processor lacks PCM controller. So, I want audio to go through HCI.
My setup is the following:
- bluez 5.31
- pulseaudio 6.0 with bluez5 module support
- ti wl18xx driver and firmware 8.5R, TIInit_11.8.32.bts file
I am able to pair and connect to headsets, so I think driver + bluetooth stack is fine. After connection, pulseaudio creates bluetooth source (thorugh module-bluez5-device), but no sink device, the one I need for my streaming application.
* Question: why isn't pulseaudio creating sink device and how can I create it manually (i.e. thorugh pactl or pacmd)?
Please consider module-udev-detect is not loaded (only module-detect) because my linux distributions lacks udev support. So no hoytplug support is present.
