Routing phone call audio through external audio system

I’m sure someone has solved this, but searched several ways without success.
I have an HTC device with an USB out for headsets. I want to be able to route the phone conversation through an audio system so folks in the room can hear both sides of the conversation. I tried USB to 3.5mm adapters, but it seems that this scenario is used for listening to the media player, and not for the “phone calls”. Any thoughts on how to do this with adapters/converters?
If this has already been done, a URL referral would be great.
Thanks,

normaly when in headset mode
be it wires using extUSB or bluetooth
all audio that otherwise would be played
by the speaker is played by the extusb or bluetooth headset
at least that how it's been working for me
since xda2
Agreed, but I am having trouble finding adapters. All the USB to 2.5/3.5mm are for "music" and don't seem to work when in "a call". Thoughts?

bluetooth microphone for pc

i've got most everything working over bluetooth
been able to make file transfers, import contacts and sms via bluetooth
but i set out on this project in hopes to have a working microphone for my pc using the phone and/or earbud/mic with oem htc adapter
i do not own a bluetooth headset and my pc is across the room...so figured this is worth a shot
first
my setup:
sprint touch pro on ppcgeeks clean bazzle rom (fairly recent build)
IVT Bluesoleil 6.4.249.0 (PC bt app)
HK-730 usb dongle (pc) (it is bt 2.0 +EDR and yes a2dp capable)
The IVT software seems to function and i am shown via right click the ability to mute advance audio, which is semi working (all i get is static).
The bluetooth sco audio microphone shows in my pc audio recording devices, but when unmuted by IVT all i get is clicks and static
It somewhat responds to my voice...i mean the sound meter grows somewhat correspondingly...
but nothing is coming through...besides strange click sounds and static.
i'm so close i can taste it...
my first thoughts were the sample rate and bitdepth
the pc speaker outputs are selectable...but nothing near the mic recording rate
i may be up the creek as my pc has an inferior realtek audio alc662.
My other thought was some kind of setting on the phone.
Hands free,stereo audio, & com connections are all selected in the bluetooth settings for the connection to my pc.
i figured it was worth a post on the forums for some possible solution
first I would read the info about how to get a normal bluetooth headset working as mic on a pc
http://www.google.com/search?source...set+as+mic+for+pc&aq=f&aqi=&aql=&oq=&gs_rfai=
could very easy just be
1. your pc's bluetooth stack don't support that bluetooth profile
2. your fuse don't support that bluetooth profiles

USB audio

Hey I heard with lollipop we would have USB audio. When I connect my nexus 5 to my car through a USB cable and play some music it doesn't play from the car speakers. Whereas an iPhone was able to play music. Any help on how to make it work would be appreciated.
Probably your car audio needs a software upgrade to work with Android devices/L's USB DAC support.
Your car is looking for a file system, android USB audio is providing stream not a file system so this probably wont work unless the deck can emulate a small sound card or something to accept the input.

GROM USB Audio out works with my Verizon Note 4. Kinda.

So I just purchased a GROM Audio Honda Acura 03+ USB Android iPod Bluetooth AUX adapter( SKU: HON1U3 )
http://www.gromaudio.com/store/usb_...uetooth_adapter_direct_digital_interface.html
With both the Bluetooth and USB AUX adapter it came to a pricey $229.96. What I got for that price is:
Bluetooth media and headphone profiles
USB out via AALinQ Car Music Player
OK Google Hotword still works
Con's:
You have to load your media into the AALinQ application to get it to play via USB, that means no Google Play music over USB, and all system sounds aren't automatically sent to the USB audio like with the Note 3 and previous Galaxy devices.
You don't get track titles etc via Bluetooth at least with my Note 4 on my '08 Acura MDX and the GROM connected to my XM 2 Sat input on the stock head unit.
I'm getting a weird slight crackle when audio stops and starts playing via Bluetooth, I think this is because the Grom adapter is connecting and disconnecting USB audio to the head unit, I got the same crackle when connecting my MHL USB audio connector when the car head unit was on.
Pro's:
The nice thing is that unlike a dedicated MHL USB connector which is the other way to get USB audio out on the Note 4 you aren't blocking your microphone while connected
You are charging. which I hadn't got working with USB to MHL.
Just thought this might be useful to those of us who don't have A2DP built into our car stereo's. GROM is compatible with hundreds and hundreds of vehicles, just use the Browse by auto make selector at http://www.gromaudio.com/index.html
I don't work for GROM, I paid for my unit myself, wanted to share what worked for me in case it helps one of you.
Oh and according to their FAQ the charge you're getting is 1A 5V http://www.gromaudio.com/support/usb-faq.html

[Q] [Android] Auto connecting to higher priority bluetooth device

Hi!
I am searching for some technique/app or something on Android for changing connected bluetooth audio device when a higher priority device wants to connect to phone. What I mean:
1) I have bluetooth headphones which I am using to listen to music and phone calling.
2) I have bluetooth car audio which I am using for phone calling while driving a car
I looking for the option to stay connected to headphones when entering a car. When a car audio wants to connect then phone should disconnect headphones and connect to car audio (car audio have higher priority in this case).
Thanks for any answers pointing me to right direction.
