@DEFAULT_MONITOR@ finds the default sink but returns is_monitor true.
Always lookup the device based on the name and index. This transform
the special device names like @DEFAULT_XXX@ to the default device.
Always use the found device name as the target. Make sure to set the
CAPTURE_SINK property when dealing with a monitor.
Fixes#3284
On musl, `pthread_t` is a pointer type, so printing it
as a long generates warnings. So cast it to `void *`
and print it with "%p" since it is actually a pointer
even on glibc (nptl) (at least at the time of writing...).
Make NTP timestamps based on CLOCK_REALTIME.
Handle socket errors.
Some devices want at least 1 second of latency between RTP and NTP
timestamps or they stay silent. A a raop.latency.ms property for this
purpose that defaults to 1 second.
It is said that all devices seem to add 250ms of extra playback delay,
so include that into the delay reporting.
Fixes#3247
Use snd_pcm_htimestamp to get both the available space and the timestamp
when this was calculated. We can then use this to get a better estimate
of the delay in the device against the graph start and get a more
reliable delay between capture and playback.
Use separate values for the number of available samples in the
ringbuffer and the delay in the device.
When using htimestamp we can use the tstamp to get a more accurate delay
value against the graph start time.
Let the driver keep announcing.
Keep track of when a message was received in the driver. If we don't
receive anything for a while, reconnect.
Don't connect twide in the manager.
`pw_reallocarray()` leaves the newly allocated storage (if any)
uninitialized, so fill the bytes of the new `spa_param_info` objects
with zeros in `pw_{node,port,device}_info_merge()` to avoid handing
out pointers to uninitialized storage.
The module advertizes itself on multicast and will trigger a new client
in the netjack2 manager. Tested with jack2 and 'jack_load netmanager'.
The driver will receive and send data (no midi yet) from and to the
manager in sync with the manager, without resampling and with a fixed
latency.
