Bluetooth Audio - Samsung Galaxy Note 9 Questions & Answers

My Nofe 4 was rooted and I'd installed Viper4android and its Bluetooth settings had fixed buzzy audio that I was getting with my Bluetooth connection. Unfortunately I cannot use the app on my Note 9 due to the lack of root available.
This is my setup for my vehicle;
Cassette Adapter to Male 3.5mm plug
Female-to-Female adapter & Line filter
Kinivo BTC450 (Male 3.5 mm plug to Bluetooth device)
I've tried the Bluetooth connection with a stereo receiver. No buzzing what-so-ever. Sound was as perfect as can be (for not being hardwired).
Any thoughts on an app can use?

I have given the OP on this thread a massive makeover. Hopefully, it clears up what I had, currently have and what I'm going for.

XDA Carkit

Does anybody know:
Is it possible to connect my car speakers to the O2 XDA Carkit directly ?

Nah, not enough power. You need your car stereo as an amplifier. Alternatively, you can buy car amlifiers which are only amplifiers, but then make sure you don't end up buying a so-called 'booster', because it is meant to amplify a signal which is already at speaker level even further, for those that have sacrificed all space in their trunks for sub-sub-sub woofers and other tools for terrorizing their fellow humans.
You could try a £10 maplin cassette adapter, http://www.maplin.co.uk spliced onto a o2 xda headphone cable. You can use the nokia adapter version straight from the box, as the connector is the same size, but it is mono. Hence why I adapted a spare xda headset instead, as I thought the button on the mic pod might be useful, not to mention portable between different cars.
However, I have had problems with "transmit" noise using this "lash up" method. So its not perfect, but to be honest if you want music playback or tom tom navigator audio output its excellent.
Does anyone know if the external amp/back input of a hifi would stop the reception of the transmission noise during a call/gprs exchange. I'm using an old crappy car stereo without a seperate input, and the car is probably worth less than the xda as well! hence the cassette adapter method. :wink:
The MP3/Headset Audio Adapter from the other thread may be a solution?
It's a O2 Carkit with 2 outgoing speaker cables.
If i connect it directly to the cables that are coming from my car radio, will that work or will it blow up my xda.

it works through a standard nokia car radio relay kit
it works through the nokia car radio kit that was already in my car with my nokia phone, I simply plugged the radio relay kit intop the speaker socket of the O2 car kit and joined the yellow mute wires together.

Bluetooth -> Aux Audio

Hi all,
is there a (cheap) solution for transmitting a Bluetooth signal (over my HD2) to Aux Audio? That would be great! Oh and I'm not looking for this for my car, but for a stereo music box (hope this is right word in English!)
greats!
Check these out ..... i bought them froom woot for 12$ ...you can connect ur cell phone to it using btooth and then put the aux cable instead of headphones..

And if you still decide to use it also as a handsfree for calling purposes check the sound quality of the mic before buying (call few friends with it and ask them if they hear you). I did not do it and now I have to use my Philips shb7100 just for listening music over a2dp because the mic is crap (or the AD conversion mechanism)
Bluetooth® Home Stereo Adapter DC800 [Motorola]
I use Motorola Bluetooth® Home Stereo Adapter DC800. this was a costly item 5 years back running up to 100 USD...but now a days you will find seconds everywhere on line and even the new one's shouldnt be too costly....
I am very happy with the performance...I connect my HD2 to this by Bluetooth
And DC80 has a output wire to my Home Theater....and it plays wonderfully.
I also have a Input wire into DC800 from my TV headphones jack....this allows me to use my Motorola HT820 headphones to listen privately late night shows when others are asleep....
try to find them in your country,..who know you might get a good deal on ebay/online.....

[Q] Bluetooth streaming guidance requested

Hey everyone, pretty sure there is a better place for this post but not really sure where that would be. I'm looking for a bluetooth device to stream music from my Xperia Z3 Compact to my car stereo.
My stereo has a female usb cable and an aux cable running next to each other into the try below the stereo. What I am looking for is a device similar in construction to a usb stick, ie something that plugs directly into the usb port and is powered there but is relatively small. if it has to play the audio through the aux cable that is fine. I've seen some devices like the:
VicTsing Portable USB Bluetooth Audio Music Streaming Receiver Adapter with 3.5 mm Stereo Output White I found on amazon. (sorry too new to post links)
However, its been a long time since I used bluetooth and I remember my bluetooth 2.0 device being a huge power drain. I know that's supposed to be the big thing with bluetooth 4.0. So I guess all in all I have the following questions:
Is there a good device like this out there with bluetooth 4.0?
does it matter to my phones battery whether or not my Bluetooth 4.0 phone connects to a 4.0 receiver versus a 2.1 receiver?
Is there a better device out there that can transfer meta data to my car stereo as well via bluetooth connected to the usb?
Thanks for any help and Iike i said, if this isn't the place for such a question please redirect me there and I will re-ask it.
Thanks

Neet® - Bluetooth Stereo Music Receiver - High Quality HiFi Audio - Wolfson DAC - Wir

Hi All,
This may be a really stupid questions so apologies in advance, I've just purchased the Neet® - Bluetooth Stereo Music Receiver - in order to connect it to my bit ten d via the toslink optical rather than using RCA cables. .
By adding this unit to my system, would i be able to direct all sound / calls etc from the head unit via blue tooth to the Neet receiver rather than using RCA cables.
Due to the low voltage on these units, the sound quality is terrible.
Tanks
well unfortunately, it doesn't work. It seems to find the neet Bluetooth receiver but doesn't connect.
