Hi,

thank you for the feedback. Unfortunately the microphone is not
supported yet. If you put profile "auto" into the .asoundrc you get

# arecord -D bths1 -f S16_LE | aplay -D bths1 -f S16_LE
ALSA lib pcm_bluetooth.c:1619:(bluetooth_init) BT_GETCAPABILITIES
failed : Unknown error 240(240) arecord: main:590: audio open error:
Unknown error 240 aplay: playback:2208: read error

and you see that the alsa is not able to open the bluetooth input
device. I use my bluetooth headset and notebook with built-in
microphone to use Skype with the configuration as described here [1].

As of the PulseAudio (PA). The 0.9.12 version does not provide you with
microphone support either, even if you succeed to set it up. The PA
receives/sends the sound via module-alsa-source/module-alsa-sink
from/to alsa again. wait for the PA 0.9.13. There will be PA native
bluetooth support.
