This introduces the following changes:
* Using the time at which the command was received
* Preparation for the unsollicited notifications
* New folder holding all the AECP_AEM commands/responses and utils
* Improving the code-reusability by using common handlers
Add feedback and feedforward controls to the delay. This makes it
possible to make comb and allpass filters with the delay to build
custom reverb effects.
built:
* es_builder: create stream with state variables and counters
* acmp: do not use the stream list, go through the descriptor to find
the index
* stream: do not store redundant information such as the index and
descriptor
* internal: removing the stream server and function associated to it
module-avb: internal, stream: removing server_find_stream
The dont-inhibit-auto-suspend flag does not do anything when using
direct-on-input-idx (capturing from a stream) in pulseaudio, so also
make it do nothing on pulse-server.
See #4991
to attach ressource to the descriptors instead of having them splitted.
It is the case for the avb-streams which in a seperated list. Instead they
should be encapsulated within the descriptor itself, as one cannot leave
without the other.
Refactor the IR loading code, Make some generic open/load/close
functions and handle the different filenames in the open call.
This makes it possible to reuse some of the delay and alloc code.
It also makes it easier to add new IRs loading code.
Support /IR:<rate>,<value1>,<value2>,... as an inline IR definition.
The associated cases where IGMP membership is silently dropped may happen
infrequently. But when they do, these log lines can occur at a large
volume. To not spam the logs in such cases, change the log level from
info to debug.

Add a new thread.reset-on-fork property for the thread creator. when set
to false, it will clear the default SCHED_RESET_ON_FORK flag and new RT
threads will be able to fork and inherit the rt policy and priority.
When creating a thread make sure we set SCHED_RESET_ON_FORK when the
thread.reset-on-fork property is not explicitly false;
module-rt needs to preserve the SCHED_RESET_ON_FORK flag when changing
the policy.
Set thread.reset-on-fork=false explicitly for JACK clients to restore
the JACK behaviour where implementations can fork and inherit the RT
policy and priority by default.
Fixes#4966
This reverts commit 3eb011c9d1.
Not a good idea, the internal signals are for scheduling peers and so
some peers are simply not signaled when they don't need to be scheduled,
like for async nodes or upstream nodes.
Forward existing impl-node peer_added and peer_removed signals on the
stream.
Because the stream is not on the server, there is no impl_node in the
node target. Add the node id to the peer_added/removed signal and use
that for the stream event argument. Implementations can then look up the
details on the global.
When a device profile changes (e.g., Bluetooth headset switching from
a2dp-sink to headset-head-unit), the active port information changes
but PulseAudio compatibility layer clients don't receive the expected
PA_SUBSCRIPTION_EVENT_SOURCE or PA_SUBSCRIPTION_EVENT_SINK change events.
Root cause:
The collect_device_info() function updates the active_port index from
SPA_PARAM_Route parameters, but doesn't update the corresponding
active_port_name field. When update_device_info() uses memcmp() to
detect changes in the device_info structure, it compares the entire
structure including active_port_name. If the pointer value doesn't
change (even though the actual port changed), no change is detected,
and the change_mask flag (PW_MANAGER_OBJECT_FLAG_SOURCE/SINK) is not
set, preventing subscription events from being sent.
Solution:
After setting active_port in collect_device_info(), look up the
corresponding port name from SPA_PARAM_EnumRoute parameters by
matching both the port index and direction. Initialize active_port_name
to NULL at the start to ensure it's always recalculated.
This fix applies to all device types (Bluetooth, USB, PCI sound cards)
and all profile switching scenarios, ensuring applications using the
PulseAudio compatibility layer receive proper device change notifications.
Tested with:
- Bluetooth headset profile switching (a2dp-sink ↔ headset-head-unit)
- Applications subscribing to PA_SUBSCRIPTION_MASK_SOURCE/SINK events
- Verified no regression in audio initialization
Add IGMP recovery mechanism that monitors RTP packet reception and
triggers multicast group refresh when no packets are received if
a deadline is reached. The deadline is configurable via a new stream
property "igmp.deadline.sec" (in seconds), with the default value
being 30 seconds (and a minimum of 5 seconds).
A timer checks regularly if the deadline was reached. That timer's
interval is set by the igmp.check.interval.sec property (in seconds),
with the default value being 5 seconds (and a minimum of 1 second).
When the deadline is reached, the mechanism performs IGMP leave/rejoin
operations to refresh multicast group membership. This ensures RTP
data continues to be received when network conditions cause IGMP
membership to expire or become stale due to router timeouts or
network issues.
Add IGMP recovery mechanism that monitors SAP packet reception and
triggers multicast group refresh when no packets are received if
a deadline is reached. The deadline is set to half of the cleanup
interval, with a minimum of 1 second.
When the deadline is reached, the mechanism performs IGMP leave/rejoin
operations to refresh multicast group membership. This ensures SAP
announcements continue to be received when network conditions cause
IGMP membership to expire or become stale due to router timeouts or
network issues.
Keep the samples in the ringbuffer that are needed the next cycle to
avoid discontinuity when the aec blocksize is not equal to or divisible
by quantum.
