how to output audio over BlueTooth?
|
|
| The PocketTV Team 2005-12-18, 3:57 am |
| i heard that on the new BlueTooth-enabled Pocket PC's each application needs
to do something special to activate output of audio over bluetooth ?
isn't this supposed to be managed globally at the OS level (i.e. as part of
the device Settings)?
but i heard that only WMP can output audio over bluetooth on those devices,
and no other audio application (game, video players etc) can do it (unless
they take some special action in the program).
i'm really surprised that it's not an OS feature, i.e. if you have
bluetooth, and a bluetooth headset, then i would hope that all audio apps,
games, etc, would work with that automatically.
that's looks like really bad...
so, does anyone have any pointer or information regarding how to do output
audio over BlueTooth?
thanks in advance.

| On WM5 there is an IOCTL which can be sent to the audio driver to divert
audio to the headset. Since A2DP isn't currently supported (Due in AKU2 in
early 2006) you'll only get mono "phone" quality audio, so while you can
play media player through a headset it's not that great.
You open a handle to "BAG0:" with CreateFile. Then send IOCTL_AG_OPEN_AUDIO
(0x01) to switch all audio to the headset. To revert back send
IOCTL_AG_CLOSE_AUDIO (0x02). AFAIK no applications do anything special to
support this - when activated all system audio goes through the headset. I
have yet to be able to try this with WM5 Smartphone but it appears to work
on all WM5 Pocket PC devices.

| ok, so the bad news is that it is only mono "phone" quality audio... :(
but since it's so simple to switch audio between bluetooth headset and
normal, howcome there is no small applet in "Settings" to do that ?
strange, really...

bluetooth is not true, correct?

| In AKU 2 there will be the A2DP profile to support stereo headphones, Once
that is implemented I would expect it to become a more useful option in
media player. However my understanding of the support (based on this
preview - http://www.theunwired.net/?itemid=2779) is that audio will be
automatically routed to the headphones once bonded.

What does AKU mean?

| Adaption Kit Update - these are the periodic updates supplied to OEMs. AKU 2
is due out in early 2006 and will feature A2DP profile and the messaging and
security feature pack.
