We don't need 2 convolvers anymore, we can use the same convolver with
2 outputs with the left and right ir.
Add latency option to the sofa plugin. I believe the latency of the
SOFA filters is by default 0, so use that.
Add support for multiple convolver outputs. This makes things more
efficient because we only need to do the input FFT once to produce the N
outputs.
Add convolver2 that can have multiple outputs.
port_use_buffers and related port methods increment port_id when the
implicit output direction differs from the adapter's primary direction.
port_reuse_buffer only receives a port id but applies to output ports,
so apply the same offset before forwarding to this->target.
Also update videoadapter for the same mapping.
MT7925 fails to setup a SCO connection that results to working LC3-24kHz
audio. Other controllers (Intel etc) appear to work OK.
Add quirk for disabling this codec, and disable it for this Mediatek
controller.
We need to deactivate the graph when the format was cleared on both the
input and output. This means we got suspended and we need to clear. We
can safely do this now because we take the right locks.
SF_FORMAT_WAVEX is not supported to SF_ENDIAN_CPU. Due to that, unable
to record in .wav file (for > 2 channels). Add case for SF_FORMAT_WAVEX
to get assign SF_ENDIAN_FILE.
Fixes#5233
The DSP port type needs to be something else than "other" for it
to become visible. This way we can also remove the IS_VISIBLE check
because we never add invisible ports to the object list.
ACP was re-selecting the “best” port on every port availability event,
even when a port was already explicitly selected by the user. This
differs from PulseAudio’s behavior, where port switching decisions are
left to higher-level policy.
This caused issues on devices where Line Out (speakers) and Headphones
share the same analog interface: when headphones are plugged in, ACP
would immediately switch away from the user-selected Line Out, or end up
in a state where no sound is produced despite selecting speakers explicitly from
clients like pwvucontrol.
Fix this by only re-evaluating and switching ports when:
- no active port is currently selected, or
- the active port has become unavailable
This preserves manual user choices and prevents ACP from fighting client
port selections during route activation.
Additionally, adjust ALSA mixer paths to better separate Line Out and
Headphones behavior:
- Disable Line Out controls in the headphones path
- Add explicit Line Out and Auto-Mute Mode handling in the lineout path
Together, these changes align PipeWire’s behavior more closely with
PulseAudio and fix cases where selecting speakers while headphones are
plugged results in no audio output.

1. The period calls were added to handle timeouts.
2. Handle the case where lock must be unlocked after 60s if the
controller owning the locked does not release it.
Takes an input file, processes it with audioconvert and writes to an
output file. Can be used to test all audioconvert features such as
resample, channelmix, filter-graph, format conversion, dither, etc.

The object, node, client, factory, module, and link IDs are all uint32_t values but were being formatted with %d.
This would produce incorrect negative values if an ID ever exceeded INT_MAX
The CHECK_PORT condition in impl_node_port_reuse_buffer was inverted with a negation operator, causing the function to reject valid output ports and accept invalid ones.
Fixes the logic so that valid ports proceed to buffer recycling and invalid ports are properly rejected.
When a node is inactive but linked to a driver, the only reason it is
not being scheduled is because it is inactive.
We already set up the links and negotiate the format and buffers to
prepare going to RUNNING. This patch now also make the node go to IDLE,
which makes the adapter negotiate a forma and buffers with the internal
node.
This makes things more symetrical, when linking a node, it becomes IDLE,
when activating it becomes RUNNABLE, when inactive it goes back to IDLE.
The switch to RUNNING will also be faster when things are already set up
in the IDLE state.
The main advantage is that it allows us to implement the startup of
corked streams in pulseaudio better. Before this patch we had to set the
stream to active to make it go through the Format and buffer negotiation
and then quickly set it back to inactive, hopefully without skipping a
cycle. After this patch, the corked stream goes all the way to IDLE,
where it then waits to become active.
See #4991
When the port is destroyed we need to remove it from the mix_list or
else the process function will keep trying to use the invalid memory.
This is because the port logic does not want to call any functions on
the port (like clearing the IO or Format) after it emitted the destroy
signal and we need to clean up ourselves.
Fixes#5221

The MD5_hash() function formats password material into a 1024-byte
stack buffer for hashing but never clears it afterward. Similarly,
the Basic auth path in rtsp_add_raop_auth_header() formats
username:password into a stack buffer without clearing it.
These buffers remain on the stack after the functions return, and
could be exposed through memory disclosure vulnerabilities, core
dumps, or memory inspection.
Clear the buffers with explicit_bzero() immediately after they are
no longer needed, consistent with the existing practice of clearing
the password before freeing in impl_destroy().

In netjack2_recv_float(), several values from untrusted network packet
headers are used in arithmetic without overflow protection:
1. active_ports from the network header had no upper bound check. A
very large value causes `active_ports * sub_period_bytes` to
overflow uint32_t, producing a small value that passes the length
check, then the loop iterates out of bounds on the receive buffer.
2. The sub_cycle bounds check `sub_cycle * sub_period_size >
quantum_limit` can overflow, allowing a large sub_cycle to pass
the check and cause an out-of-bounds write when computing the
destination offset.
Fix by capping active_ports to MAX_CHANNELS, casting to size_t for the
length check to prevent overflow, and rewriting the sub_cycle check as
a division to avoid overflow.

Memory Safety: High
In netjack2_recv_midi(), the offset calculation `max_size * sub_cycle`
uses sub_cycle from an untrusted network packet header. A large
sub_cycle value could cause integer overflow, producing a small offset
that passes the subsequent bounds check and leads to an out-of-bounds
write into the MIDI data buffer.
Similarly, the bounds check `offset + len < midi_size` could itself
overflow, and the `used` size calculation from network-controlled
event_count and write_pos fields could overflow to bypass the size
check.
Fix by adding an explicit overflow check before the multiplication,
rewriting the bounds check to use subtraction (which cannot overflow
after the prior check), and adding an underflow check on the `used`
calculation.

In ensure_size(), the check `m->length + size <= m->allocated` could
overflow when both m->length and size are large uint32_t values,
wrapping around to a small number and incorrectly passing the bounds
check. This could allow writing past the end of the allocated buffer.
Rewrite the check as `size <= m->allocated - m->length` which cannot
overflow since we already verified m->length <= m->allocated. Also add
an explicit overflow check for the new allocation size calculation.

In pw_conf_save_state(), the return value of fdopen() was not checked
for NULL. If fdopen() fails, subsequent fprintf() and fclose() calls
would operate on a NULL FILE pointer, causing a crash. Additionally,
the file descriptor would be leaked since fclose() would not be called.
Added a NULL check after fdopen() that closes the raw fd and returns
an error on failure.
