Daniel - Bluewave,
I looked at many posts and asked for help before, but so far I'm stuck. I can't seem to get my microphone working properly in OAP. It works fine in Raspi, but not in OPA.
My hardware:
iPhone 8 Plus
Pi4 8GB
UGREEN USB sound card
Microphone that works in Raspi with UGREEN attached to Pi
Touchscreen
Recommended wired Carlinkit dongle (working)
Wired Bose speaker for testing purposes, plugged into UGREEN sound card - Pandora and others playing fine over it
BT dongle - Kinivo BTD-400
32GB San Disk card - new
Fresh installation of OAP 16 flashed on card with Raspi fully updated
Problem description:
I made sure the microphone works by recording my voice in the console using this command: arecord --format=S16_LE --rate=16000 --file-type=wav out.wav
It recorded fine and played back fine. Based on that I made the assumption that the dongle worked fine - maybe that was wrong of me....
When I go into OAP, with my phone connected to Carlinkit using Carplay, covering my phone with a pillow and speaking directly into the microphone as before, I get nothing. Saying "Hey Siri!" does nothing. I don't know what other phrases OAP uses to communicate, if any, but "Hey Siri" doesn't work.
Found this in the FAQ section:
Q: I use external Bluetooth adapter and successfully paired my Phone with Raspberry PI but callers do not hear me during a call. What is going on?
A: Please double check that you use Bluetooth adapter that is not based on Broadcom chip. Adapters based on Broadcom chips have broken SCO routing and will not work with Hands-Free calling.
I have a Kinivo BTD-400. Under specifications it does not say if it uses a Broadcom Chip, but it does say this:
Broadcom Bluetooth Stack available for Windows 7. Works with Raspbian and Ubuntu on Raspberry Pi.
Can someone verify if this BT adapter is fine or is it one of the problem adapters. From the description it doesn't sound like it has a Broadcom chip installed, but that it can run Broadcom protocol with the Stack.
Edit: Checked on the Kinivo website and now it seems this is one of the adapters with Broadcom chips. Accordingly:
Under Linux Driver Installation:
The Linux kernels after June 2012 have the drivers for the Broadcom Bluetooth chipset.
Let me try another BT adapter.
Sound Blaster WUSB6300 V2 - higher speeds available using USB3, but it wasn't recognized by the Pi. Checked with Tech and for whatever reason they said only Win drivers available??? Did a search and found that Linux 88x2bu drivers should work. I just installed them and am about to boot up...............................................
