Hi!
If you had a register dump from android with mics working, preferably not in speaker mode, perhaps I could try to figure it out?
OK here are four diffs against starting the phone app for regular call, speaker call, and muted versions of them:
http://muru.com/linux/d4/cpcap/
Also, I'm connected over cdma right now, not 3g, but I doubt that makes a difference for the microphone.
Thanks!
When I apply register settings directly, I indeed get working "normal" call working. Good. Diff for illustration is below. Clearly needs some improvements.
And it shows that alsa mixers are expected to be simple and obvious on D4 -- they just do not work.
Current version of phone gui is at https://github.com/pavelmachek/unicsy_demo
- ofono interface should be usable - AT commands need a lot more work, and they'll probably never work nicely in this design. They are just a temporary hack.
(ouch, and it should be rewritten, in Vala or better Rust...) Pavel

Add support for "normal" (not handsfree) call.
