System requirements:
a. RPI3b+ / OAP 13.2
b. Custom powersupply 12V > 5V 5A
c. Sound card ugreen 30724 : 0d8c:0014 C-Media Electronics, Inc. Audio Adapter (Unitek Y-247A)
d. microphone input : yes connected on ugreen sound card
f. Touchscreen : official Raspberry Pi Touch Display 7" (lcd_rotate=2)
iPhone 13 mini
CPC200-AutoKit with microphone (https://www.amazon.fr/gp/product/B0919JPNLY/)
Firmware 2021.08.30.1821CAY
I was an happy OAP user with wireless AA (https://bluewavestudio.io/community/show...p?tid=2701) but I switched to an iPhone.
So I did buy a wireless carlik kit and the Autobox plugin.
Wireless Carplay works fine with OAP.
The only problem I have is with microphone :
It use the input of the sound card (Not the carlink one, I don't know if it is possible, but it would be less practical), and the stream is jerky and gradually be late.
So that after some times, my voice is very late for the phone caller.
For wireless AndroidAuto, I did change pulseaudio settings to add "tsched=0", so I try to remove it.
Without tsched=0, microphone works great with Carplay/carlink !
But there is no solution to support AA and Carplay with the same setup (for other car drivers with Android devices).
Do OAP14 change the andio handling ?
Finally, the microphone level is very low (wasn't better with AA), I tried to change input level in pulse mixer from 100 to 130% (max) but it does not seems to work.
Is there another solution for input level ?
Thank you,
Julien
