Routing phone call audio through external audio system - General Questions and Answers

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?

How I integrated my Trinity into my car

Hi all -
I have an older Audi a4 with the factory Concert/Bose radio. I replaced the CD changer input with one of these:
http://www.crutchfield.com/App/Product/Item/Main.aspx?g=50900&i=581DFVW&tp=1672
This allows me to input audio to my car radio using RCA-type connectors. I then got one of these:
http://www.cablestogo.com/product.asp?cat_id=2009&sku=03178
that lets me plug into a 1/8 jack and send the audio to the RCA jacks. I then got:
http://www.ppc4you.com/pages/13635.html
which allows me to pluf the 1/8" plug into my Trinity. I didn't use this exact one, but mine is similar to this one. Don't use the 1/8" converter that is in the form of a single solid piece, only use the ones that have a short length of wire between the two ends. The solid ones do not stay in properly. Also, by using the Y connector, I can both plug my Trinity into my stereo as well as plug in a regular 12v lighter power converter and power it. I then finished it off with the ProClip/Brodit cradle:

Everything works great! Once I have it all hooked in,
1.) I can play MP3's through my car stereo (useful)
2.) TomTom directions also go through my car stereo, and the music is slightly muted making directions easier to follow (very useful)
3.) Best of all, I tried calling my girlfriend (while the Trinity was in the cradle, playing MP3's through my stereo), and a.) her side of the conversation came through my car speakers, with the music muted, and b.) she said she could hear me just fine (but a little loud), which tells me the Trinity continued to use the internal microphone and amplified my voice the same way it would when set on speakerphone!
So, I now have the equivalent of in-dash navigation, integrated cellphone, and MP3 player. And I can take it with me when I leave the car! This is exactly why I bought this phone in the first place. What surprises me is that it actually worked!!! <grin>

Thanks for sharing your setup!
Good on ya!!
I share a similar story.
I drive a Mazda 3.
I installed a chip at the back of the stereo so that it allows an audio auxiliary input into my car stereo.
I then bought a 3-in-1 adaptor, car charger and mic adaptor from ebay.
This is so that I can place my craddle and phone further away, while having the mic externalised and stuck near my dashboard.
So in effect, same deal! GPS navigation + mp3 player while charging, calls get accepted no problem, and make calls via voice speed dial. Absolutely loving it.
Hey guys,
You should check out my set up, I have my Trinity on a GPS holder (suction cup), my trinity is then connected to a device like this:
http://www.oo.com.au/MP3_Player_Car_Modulator_FM_T_P5477C75.cfm
It accepts USB drives to play MP3's through the FM Transmitter, however I used the USB port to power my device, and the 3.5mm port (this allows you to plug in other devices and play through the device via FM) goes to my Bluetooth handsfree (i-Tech Radio Clip).
From here I have an ultimate wireless solution apart from the recharging, however Bluetooth really takes a lot of memory and slows the Trinity, however music plays and Tomtom works! no issues with that, the Radio Clip has remote functions so I can change music while Tomtom is still on, I don't have to minimise Tomtom and go to WMP to change music, I just do it on my Bluetooth device.
However this isn't a perfect solution, as Bluetooth really takes a lot of memory
I looked into using an FM transmitter approach, but there are a lot of FM stations around where I drive, so finding a clear channel gets to be a pain. Also, I'm stupidly picky when it comes to audio quality, which is better using a wired solution rather than the FM solution. Looks like a good apprach though!
hey guys
I bought a £50 car stereo from Lidl
which has a usb port
superb
x
In most cases with FM Transmittors and it depends on the FM Transmittor, it usually dominates the FM Channel, so if you had it on say 104.1 in which in Australia is 104.1 Today FM as long as the Transmittor is nearby and close to your aerial it is all good!
But yeah, I feel that bluetooth and FM Transmission can cause quality lose in Audio, however sometimes I can't tell the difference, I have the USB to 3.5mm converter and I was dumb enough not to find the USB and 3.5mm unit, which was available at that time, but oh well, alls well ends well.
http://cgi.ebay.com/ws/eBayISAPI.dl...item=160180673140&_trksid=p3984.cWON.m313.lVI
I bought this one and works great, it has everything I need, but when I connect it to my stereo, the music has no bass. Still have to figure that one out. Any ideas?
I have a small 2.5mm to 3.5mm adapter, then connect that to one of those tapes with 3.5mm jack. It works great on my PSP, but with my phone the bass is gone. I have 1.23 with GPS and WM5. I have to try different player (Using WMP) and the HTC equalizer & audio manager.
Anyway, I love the setup, everything is together into a cool device.

Hey! Exactly the same setup I had with my old Magician! I had glued the 2,5mm jack to the Brodit holder, so it would connect power and audio at the same time. It was a treat to use!
However, now I have a Sony BT2500 Bluetooth car radio and don't need no connectors (besides USB power) any more.

I have a similar configuration, on my alpine stereo.
Sound quality is great and everything works as you told.. very good but,
when i have a call, i can hear very well from my car speaker but the other side can't hear me my Trinity don't continue to use the internal microphone. I'm quite sure it's a trouble by audio jack to htc usb converter: every post i read i found only Y cables (audio and input power)... mine is 3 way: http://www.gpsforless.co.uk/product_details.php?id=7920
Or maybe a rom trouble? i'm using Bepe's 0.79 WM6...
does exist a cab file witch forces trinity to keep using internal microphone always??
i'm planning to buy a new radio with bluetooth audio streaming capabilities for my Trans Am.
probably this radio:

Raphael use Handset Microphone with Headset plugged in

Hi there,
I've got a simple problem to solve: When in my car, I have my Raphael plugged to the car stereo with a cheap ExtUSB Adapter. The phone recognizes the adapter as a Headset, but I don't have a microphone attached.
When someone calls, I want to use the headset Audio but with the handset microphone.
Is there any easy solution for this? Putting the phone to speaker mode works sometimes, but the phones speaker isn't loud enough for most situations.
thx, h3po
push...
another situation, same problem:
I just bought a cradle for my Raphael which happens to have a built in microphone and a line-out jack, which I do not plan to use. But when I plugin my handset, it goes to headset mode and I cannot hear the ringtone when the phone rings.
I can't believe there's no way to choose the speaker output =/

[Q] Audio to non A2DP headset

Hi,
I'm wondering if there is any way to stream audio music and/or FM radio from Windows Phone 7 (I have the HTC HD7) to a non A2DP Bluetooth headset (I have the Jabra EasyGO).
It seems that I can only make and receive calls with it.
I've searched all over the place (and web) and cannot find a way to do that.
The only way is to get a new Bluetooth headset with A2DP capability?
Is there is a workaround, please let me know.
Thanks.
I don't know of one. As far as I know, the Headset profile is mono-channel only (plus another channel for the mic) anyhow, and probably quite low bandwidth, so it would likely sound awful.
Thanks for your answer GoodDayToDie.
But I don't mind for quality... Actually I'm not interested to listen for audio.
I just want, for example, to hear drive directions when I'm driving using navigation software (Navigon) instead of hearing from the loudspeaker.
Hmm... I thought the phone *would* use Headset profile for driving directions. Weird. I find the WP7 implementation to be so bad that I prefer to keep using a 4-year-old Garmin Nuvi instead, but I could have sworn I tested it and it came over the BT (and my car only has Headset, not A2DP). Maybe poke around in Settings?
Alternatively, if your car has Aux In, you could use a ripping cable (double-ended headphone cord, they're very cheap) and then the phone will play instructions over the cable into the car's stereo. This is also a great way to use the phone's music player, including Zune Pass if you have it, to play music in the car (I do this all the time). It uses less battery than having Bluetooth transmitting constantly would anyhow.

Help with Bluetooth (media streaming vs. in call audio)

I use a USB bluetooth dongle with a 3.5 mm headphone jack in my car in order to stream music from my phone. I plug the dongle into the lighter outlet for power and then connect the dongle to the aux jack in the car's stereo. Everything works great when playing any media. However, it won't connect for call audio. If I were to dial a phone number, the sound from the key touches play through the radio, but as soon as the call connects the audio plays through the phone's earpiece. I am not able to get the in call audio to stream through my bluetooth. When I go to the bluetooth settings, I see an option for media audio and nothing for in call audio. If anyone can help me get this fixed, that would be great. Also, I am on CM 10 RC 1, but this did the exact same thing on stock touchwiz.
Bump
I have the same issue on stock. This thread isn't the same as what you're asking, but he does state that he is trying to find a workaround to the same issue.
http://forum.xda-developers.com/showthread.php?t=1875877
Thanks for the reply. However, my issue is that once a call connects, the audio goes through the phone's earpiece. I can only stream media (youtube, Pandora, music, etc.) through Bluetooth, but calls won't connect to my Bluetooth setup at all.
I really hope someone has a solution to this.

[Q] How to enable Audio output via 2.5mm jack and Bluetooth

Hi All,
After much searching for this simple request, how to enable Audio output to the headphone / 2.5mm audio jack and output to bluetooth speakers at the same time.
This is not a request how to get music to play on bluetooth mono headphones etc.
I am wanting to have my Nexus 5 plugged into the speakers and amp in one room, then also have my UE Boom in the next room playing audio via bluetooth.
As soon as I plug in the speakers via the jack, the bluetooth sound output is muted.
Going into Bluetooth settings and unticking music and then ticking music starts audio playing via bluetooth but stops audio via 2.5mm jack.
Any settings I need to know about? Apps or custom ROMs to do this simple feature.
Think of this as a keep playing to speakers when headphones are plugged in. Possible in Ubuntu, is it possible on Android?
Many Thanks,
Rob.

Just to bump the thread, as I know how fast paced the Nexus 5 forum is, and I have waited 10 days before re-asking.
Anyone with information that could help?
Many Thanks,
Rob.
