Hello,
Sorry to bring this up again. However, I cannot use pulseaudio 8.0 +
bluez5.38 to record audio from my Bluetooth's microphone.
- I followed the patch from link below to apply it on top of my embedded's
board which is running 3.14 Linux kernel:
https://lists.freedesktop.org/archives/pulseaudio-discuss/2015-March/023305.html
I can successfully switch to headset_head_unit (HSP) profile. Below is the
output of sinks|sources and how I choose Bluetooth's microphone as the
default audio source:
# *pactl list sources short*
*0 alsa_output.0.analog-stereo.monitor module-alsa-sink.c
s16le 2ch 44100Hz IDLE*
*1 alsa_input.0.analog-stereo module-alsa-source.c s16le 2ch
44100Hz IDLE*
*2 bluez_sink.00_1F_81_34_08_22.monitor module-bluez5-device.c
s16le 1ch 8000Hz IDLE*
*3 bluez_source.00_1F_81_34_08_22 module-bluez5-device.c s16le 1ch
8000Hz IDLE*
# *pactl list sinks short*
*0 alsa_output.0.analog-stereo module-alsa-sink.c s16le 2ch
44100Hz IDLE*
*1 bluez_sink.00_1F_81_34_08_22 module-bluez5-device.c s16le 1ch
8000Hz IDLE*
*# pacmd set-default-source 3*
Using parecord to capture audio from Bluetooth's microphone:
# *parecord -v -r --channels=1 --file-format=wav
--device=bluez_source.00_1F_81_34_08_22 mm.wav*
*Opening a recording stream with sample specification 's16le 1ch 44100Hz'
and channel map 'mono'.*
*Connection established.*
*Stream successfully created.*
*Buffer metrics: maxlength=4194304, fragsize=176400*
*Using sample spec 's16le 1ch 44100Hz', channel map 'mono'.*
*Connected to device bluez_source.00_1F_81_34_08_22 (index: 3, suspended:
no).*
*Time: 0.026 sec; Latency: 25844 usec.*
=> In my case, the result is a mm.wav of zero bytes no matter how long I
record.
The output from pulseaudio's log is:

It would be great if you can give my any advice or suggestion.
