nope - I use the cubieboard 3 (Cubitruck) with the Debian 8 Wheezy 3.4.106 (March 28, 2015 version)
DE=Xfce4.1, HDMI video ans ound goes to the 3.5mm audio output.
I will go back o the system within the next few days and will post my pavucontrol settings. In the meantime you can play around with various settings and watch the "input" part of pavucontrol. The bar should be moving according sound levels.
beerstein， I have try different setting, it still has same problem.
In A20, i don't use pulseaudio and it can normaly record audio and play audio at the same time.
i have test it just now. i use the new cb2 (wich mic ).
test way is same:
capture audio use the alsa-lib command:
#arecord -vv -t wav -f S16_LE -c 2 -d 10 -r 24000 ./record.wav
at the same time i play audio
#speaker-test -t wav
it seem that the CB4 sound drivers maybe has problem. do yo think?
Still send your pavucontrol settings, i will try it . if you have cb4 board, help to try it .
Thanks a lot.
