Hi!
Hmm well I got audio call hacked to work as a proof of concept hack, see below. Maybe it can be used to verify some of the assumptions above.
Then.. To split the work a bit, can you guys maybe try to decode the cpcap register values and try to do a proper ASoC driver patch?
This is not proper patch yet, but it should be a step in that direction...
Cool :) Microphone still does not work for me.. I tried tweaking the alsamixer settings but no mic. This is with cold boot with droid4-kexecboot if that might make a difference, we may have some register uninitialized somewhere. Any ideas?
Ok, I was focusing on the speaker side.
alsamixer, tab to go to capture settings, set it to 37 37 Mic2 Mic1 should work, according to my notes, but not recently tested and not tested against real human.
In alsamixer after setting the second "Speaker" to "Voice" and "Mode" to "Call" and "Left" to "Mic 2" and "Right" to "Mic 1" and doing a test call the mic does not work, speaker works though.
After the call in alsamixer, setting the second "Speaker" to "HiFi", and "Mode" to "Normal" mode, I can record a wav file and play it back just fine. But this only works for me after reloading snd-soc-cpcap.ko after the voice call.
I'll attempt to test it, but something in my userland shuts down system just after boot 60% of time, which is rather annoying.
Hmm battery voltage too low? We have cpcap_battery_irq_thread() call orderly_poweroff() on lowbpl interrupt.
FYI, I got one of the remaining n_gsm issues tracked down yesterday, at least one more bug to go. Things only work with n_gsm debug enabled right now for some reason..
I don't know why I need n_gsm, but I have my fingers crossed. :-).
More features it seems :) But sounds like you're all set for now with USB access.
Regards,
Tony
