Dear Francesco, I just did the test on latest Guppy, using a webcam as input microphone. In my case, this is a Creative Socialized HD, seen as hw:HD by alsa. I changed to /usr/libexec/agl/4a-hal/etc.available/hal-4a-rcar-m3kf.json to set it in the capture section: "captures": [ { "uid": "HD", "cardid": "hw:HD", "params": { "rate": 48000 }, "source": { "controls": { "volume": { "name": "Mic Capture Volume" }, "mute": { "name": "Mic Capture Switch" } }, "channels": [ { "uid": "mic-mono", "port": 0 } ] } } , And changed the bluetooth section to use it: "params": { "sco": { "mic": "HD", "zone": "full-stereo", "delayms": 200 }, "a2dp": { "zone": "full-stereo", "delayms": 1000 } }, With this setup, there are no more errors in agl-service-4a. But what I can see (I shoud say, 'hear'), is that only "SCO listen" works, from the remote caller, there are no audible sounds in the speaker, just like the mic was muted. However, what the remote caller says, goes through the m3ulcb speakers. This is something that needs deeper investigation, probably at the bluez-alsa level.
