Yes, that is how it behaves.
Policy rules can be changed per product, but there is no way an
application could bring in a new rule.

Thx! Sami .
So as I understand, policy unaware apps don't have to request for resources.
They just have to start using it? And ohmd will cork or uncork the resources as
and when it desires?

Subject: Re: [MeeGo-dev] Audio policy -- Adding one's own resource class
Hi,
Resource policy daemon (ohmd) has an enforcement module in pulseaudio.
A policy-unaware application may play sounds, but the streams are corked
if there are higher priority streams playing.
This means the audio from anroid app is not audible during phone calls,
and the application does not even know this.
The musix player in handset images is policy-unavare. It keeps playing
happily during phone calls and ringtone, although music does not come
out. When ringing or call ends, music is again routed out.
If I recall correctly, recording is not enforced. Application can
record, but nothing guarantees that some sounds are played
simultaneously. "player priority" is just a name, recording is also
possible.
I don't know of any way to prioritize policy-unaware apps/streams.
Instead their audio streams are mixed together. (I think...)
But then, I may remember things wrong.

Thanks Tukka . I have aa few questions about policy unaware apps:
If the apps don't ask for the permission (policy unaware apps), they are
all going to be treated as media players. In this case, how can they
know if they are granted the permission to use a particular resource
set? For instance let's assume a policy-unaware Android app wants to
play audio through the speakers while the speakers are already in use by
a higher priority app. In this case the policy framework denies the
permission; how does the policy unaware app get notified?
Is there a way to give different priorities to policy-unaware apps? For
example, an phone call should have higher priority over the audio player.
What happens if a policy-unaware app wants to record audio? I guess that
is not going to be possible, since all policy unaware apps are treated
as media players by the policy framework.

Hi guys,
I want to add my own resource class and alter the priorities of the
existing ones. Can anyone suggest a starting point or a pointer?

Policy settings are in the package policy-settings-basic-{platform}
package. That package contains policy rules (in prolog) and some
settings files. Looking into settings package for N900 resource classes
appear to be defined in resource_classes.pl.
It would be interesting to see what could be done with policy framework
but unfortunately I haven't quite grasped prolog.
