I am new to BT audio, but I have come across something very strange. I have a new Motorola S9 BT headset and a Cingular 8525. I have been able to make and receive calls, pause and skip songs in Media Player 10, but I had an awful time trying to make stereo play on the headset. It delivers system beeps, alerts, and ActiveSync tones to the headset. After some hard-resets, and some troubleshooting, I found this combination does indeed deliver very nice sound quality (without the A2DPfix). The problem is that it doesn't send AAC (.m4a) songs to the BT headset. I realize that there is only limited support for AAC, (WMP doesn't recognize the META data from them) but it does play them thru the phone speaker.
Why would WMP play some formats thru the BT headset and others thru the speaker?
not sure but you can use tcpmp with aac plugin

ok, so i can use WMP and listen to mp3's and all other system sounds etc through my BT stereo headset... however today i tried to play a movie in mp4 format and sound WOULD NOT redirect through my stereo headset, would only play through the speakerphone...
Hi,
I have never owned a BT headset before, so I have some questions if you are willing to help me.
If I read some specifications (for example from Jabra BT8010), a BT headset could have 2 modes :
- Phone mode (mono)
- Music mode (stereo)
What is exactly the music mode? Does it mean that it controls Windows Media Player?
Or it has its own media player?
How if I want to play VIDEO (using Tcpmp for example), can I use the Music mode?
Mostly I will use the BT to watch movie and play games ....
PS: Do you use Jabra BT8010 with Kaiser? How is it?
Thanks,
since i know how frustrating it can be not to get an answer..maybe you prefer a soso answer to no answer...;-):
i used to have a stereo headset nokia hs-12 or so...but this is already some time ago...
so the way it basically works: upon pairing it will say that it supports music and phone.
depending on the layout of the headset (and the achieved compatibility with the handheld device) you will be able to control some to most features of the media players in the device. like play, pause vol up vol down, FF, RWD.. my headset worked well with windows media player, also with resco radio..tcpmp i did not have at that time yet.
hope this gives you an idea.

I think the difference is that the Phone Mode or Mono mode means that there is only ONE audio channel... suitable for making and receiving calls while the Music mode or Stereo mode means that it has TWO channels which is suitable for headphones because they have to channels.
Phone Mode BT devices can play your music but only out of one channel and in all cases Phone Mode BT devices only have one ear plug.
Music Mode BT devices can play your music or any sound for that matter out of both channels which is why they are in headphone form with two ear plugs.
MONO=1
STEREO=2
This is my take on this but please correct me if I am wrong as I would too like to get to the bottom of this.
actually that is not correct.
the so called A2DP profile is AFAIK only supported by stereo BT headsets/headphones. a mono headset will NOT get any audio sound under normal circumstances. However one can tweak the registry -and there is also software that does it - in order to direct the audio output to the headset.the price for this being, that as long as this function is active, voice dialling from the headset will not work, since this is the function that is being used to switch the audio gate.
Now, in the case of the 8010 this should be different, since it is basically a stereo headset with a detachable 2nd earpice. this one should therefore always work in A2DP mode and therefore enable audio throughput without any further tweaks.
I just picked up a BT8010 yesterday -- my local Fry's had them half-price. Stereo performance is pretty good, but there's a bit of skipping (i.e. momentary dropouts of the audio). There's a firmware update available from Jabra -- that may help.
Haven't had the chance to use the BT8010 as a phone headset yet, so I can't address that.
Can I redirect the Audio player audio stream to a handsfree device? I have a blueant interphone which works great as a normal handsfree device, but as its not 'wireless audio' it means that it wont treat it as a normal headset type device.
If I press the connect button whilst playing MP3's, I hear the music in the headset for about a second before the voice dialler kicks in... so I know it can do it.. its just a matter of getting it to redirect the audio stream somehow on a permanent basis.
Does anyone know of a plugin or other hack that I could possibly use/run to turn a Handsfree device in a Audio device ?
Those who tried it before, give this another chance.
I have made a modified .cab file (Go to the BOTTOM)
- No 30 seconds limit
- Remote control works ( AVRCP)
- No skipping (Convert all MP3 to 192kbps or less)
NOW ONTO SERIOUS BUSINESS
Normal A2DP causes some hissing, sound deterioration (depending of your bitpool capacity) and hogs the phone's resources making it nearly unusable without having to pause the playback to be able to accomplish something like send a SMS.
Blueplayer has NO DETERIORATION – It uses it’s own special codec / technology
###I wish to know WHAT codec/technology is used by Blueplayer?! :O###
PROOF that Blueplayer uses a “SPECIAL” technology instead of normal A2DP
- INDEPENDENT from WM5 / WM6 A2DP drivers.
#To use Blueplayer, you need to DISCONNECT /UNCHECK the “Wireless stereo” from the phone’s Bluetooth settings (paired devices).
- NOT ALL STEREO HEADSETS CAN BE USED! ( i.Tech R35 for headphones)
WM6 A2DP stream to Laptop PC : WORKS
WM6 A2DP stream to Stereo BT Headphones : WORKS
Blueplayer stream to Laptop PC : DOES NOT WORK
Blueplayer stream to Stereo BT Headphones : WORKS
So, only special hardwares can decode whatever is the technology used by Blueplayer. It's not normal A2DP.
- AUDIO QUALITY TEST
WM6 A2DP stream to Laptop PC : Hissing
(Insanely high BitPool has no effect, and wont do skipping)
Laptop Widcomm BT A2DP to Stereo BT Headphones : Same Hissing
(BitPool can't be changed)
Blueplayer stream to Stereo BT Headphones : AWESOME!!
(skips if above 192kbps, so quality has an impact)
Blueplayer stream to Laptop : DOESNT WORK
BACK TO THE POINT !!!
I wish to know what's that technology.
Why?
Blueplayer is a HORRIBLE HORRIBLE MP3 player. All I care for is the CODEC.
The Blueplayer ITSELF is very difficult to manage.
- To pick a NEW track, you cant just click/tap it. You got to press STOP, then select the track, then press PLAY. (Or use NEXT/PREVIOUS over and over to navigate to it)
- The buttons can only be TAPPED, not clicked, and they are SO TINY that you cant just press them while walking around. You literally got to AIM your fingernail on the button, or use the stylus.
- You cant browse folders by clicking, you got to tap on a TINY TINY (+) to expand folders
- Cant select all subfolders, you got to add each folders individually to the playlist.
- No ID3 support, only a raw file list
etc etc, it's an ugly GUI.
But I want the sweet codec that makes the music sound so great.
OK HERE'S THE FILE!!!
Follow these steps to Pair your BT Headphones with Blueplayer
1 - Delete BT Headphones from your paired devices list in Bluetooth settings
2 - Set your BT headphones in discoverable/pairing mode.
3 - Launch Blueplayer
4 - Tap on "SelectDevice" at the bottom left of the screen
5 - Click on "Refresh" at the bottom middle of the screen
6 - Select your device and press the "ok"
7 - It will ask you to Pair/Add the device (WM6 Bluetooth settings does that)
8 - Once paired, UNCHECK "Wireless Stereo" from the services
9 - In Blueplaye, click on the folder icon near the top/right
10 - Browse for a folder containing directly some MP3 (it will show in the bottom list if it sees the MP3, no sub-folders allowed)
11 - Got to click the "ok" at the bottom left.
12 - Press the tiny tiny tiny "play" button and enjoy.
If you get driver errors, or the music doesnt play in your headphones and the software crashes, you dont have the hardware required to use Blueplayer.
Othewise, ENJOY THE FABULOUS QUALITY STREAMING and the CRAPPY GUI
A2DP supports several CODECs that can be used to transfer the audio over the Bluetooth link.
There is only ONE mandatory codec to support -SBC.
For SBC, normally the sound processing goes like this:
MP3 (source) --WMPlayer--> "decoded WAV" --A2DP--> SBC --wireless--> WAV (Headset)(earphones)
There is another commonly supported codec - MP3. MP3 is a much better codec for sound quality than SBC, but its much more CPU intensive to encode and decode MP3. Most A2DP headsets dont support the MP3 codec, but some (like the i.Tech) do.
My guess is Blueplayer is able to use the MP3 codec for A2DP, if your A2DP headset supports it.
Blueplayer probably does this:
MP3 (source) --Blueplayer A2DP--> MP3 without re-encoding --wireless--> WAV (Headset)
(Sorry to post in a new post - the edit post doesnt work for me using Firefox 3.)
One thing about using the MP3 codec in A2DP is that the player probably cannot do changes to the sound (no volume control, equalizer/bass boost, etc.) without having a huge impact on CPU load.
So essentially what you get is almost the raw MP3 file being streamed wirelessly using A2DP to the headset to decode. Which is a very good way to preserve the sound quality of the MP3 file.
Good find though, I'm glad to see a WM MP3 player that actually supports the MP3 codec for A2DP.
My issue is that blueplayer has a horrible GUI. While it is a great concept to stream the MP3 without reencoding, it's just... horrible.
I've always wondered why a lot of A2DP headsets can decode MP3 directly, yet there are NO software players that take advantage of it other than blueplayer.
does it work on wm smartphone
Hey guys, thanks in advance. I've done some searching and haven't been able to find anything that addresses a small oversight.
So I have an A2DP audio receiver connected to the auxiliary input in my car. It works great for music, Pandora, and what not, but none of the mono-channel phone audio gets played through my car speakers. I realize it's due to the different profiles, that A2DP was designed for music and the hands-free profiles were designed for phone calls. However, I've been able to find Music --> Mono software that allows me to play music through mono-channel non-A2DP headsets.
Is there anything out there that can help me divert the mono phone audio stream through to A2DP?
Thanks.
