EDIT: I've raised a brainstorm for this now: http://maemo.org/community/brainstor...dio_priorities

I've raised a wishlist bug - please vote on it: "Bug 6560"

Below is what I've put in the bug - any further suggestions or improvements?

EXACT STEPS LEADING TO PROBLEM:
Example senarios:

1) I'm in the car with bluetooth stereo and bluetooth headset - I want A2DP audio to go to the stereo for music and phone calls to go to the headset and all other "system" sounds to go the device and the headset - not the stereo.

2) I'm at home, have Bluetooth speakers that support A2DP and various other profiles but have no microphone - I want to be able to tell N900 to never try and use audio in for this device - and preferably never to use this device for a call.

EXPECTED OUTCOME:

The solution I want is both (or at least one) of

a) I want priority list for each service type such as "Music", "Phone calls", "System alerts", "Ring tones", "Alarm tones" I set which devices to use in order, or not at all - including the system speaker/headphones!

so can have:
"phone calls":
1) Jabra BT530
2) Jawbone Prime
3) Sony Stereo xxx
4) Wired headset
5) Internal
-) Blackbox Mini

(The blackbox has no mic so out of the list)

"Music"
1) Sony Stereo xxx
2) Blackbox mini
3) Jabra BT530
4) Wired headset
5) Internal
-) Jawbone Prime

(Although you _can_ play music on the prime - its crap, and I'd rather it go to the speakers even when I have the prime in my ear, on and connected)

b) in the Paired devices list to be able to set "controls" on every device - ie be able to set options for each device like:

- type = music / phone calls / any
- phone
- ring_tones = yes / no / exclusive
- alarm_tones = yes / no / excluseive
- system_tones = yes / no / exclusive

where exclusive means to not send to other devices lower in the priority order or internal speakers.
