Generally ALSA UCM profiles should all work as they're supposed to be
device-specific, so be more noisy when the profile fails to be supported
due to the PCM device failing to open.
Some logging on the probe outcome in failure case also makes
spa-acp-tool etc. log output easier to read.
In SplitPCM mode, Focusrite Scarlett Gen 4 (USB 1235:8218) UCM profile
specifies "CaptureChannels 2" for the Mic1/2 inputs, but
snd_pcm_hw_params_set_channels(2) fails for the HW device.
Fix by not requiring the channel count to be exact for SplitPCM, but
also allow larger numbers of channels than what UCM profile specifies.
HFP/HF/TWC/BV-03-C test, which setup an active and a held calls,
expects to receive AT+CHLD=1 (release and swap calls) instead of
AT+CHUP on active call hang up request.
As this changes the active call to disconnected and held call to
being active, the call states should be managed in hfp_hf_hangup
instead of waiting for +CIEV (callheld=0) event which will drop
the previously held call before AT+CLCC reply can inform this call
is now active.
HFP/HF/TWC/BV-01-C test creates an incoming call as soon as the SLC is
completed, i.e. a +CIEV: <callsetup>,1 event just after AT+CHLD=? reply
has been received. This try to parse the rfcomm->telephony_ag->call_list
which has not yet been created.
This commit move the telephony_ag creation to the SLC completed event.
When the pod to filter is in the target builder memory and reallocation
is needed, make sure we refer to the filter in the reallocated memory
instead of the old freed memory.
Fixes#4445
As AG, set node.rate for output streams that originate from remote
source, so that graph switches rate as needed. This follows what
pipewire-pulse etc. do.
The patch is by Wim.
In this error condition, execution is supposed to return immediately
because rfcomm is no longer valid. However, the code was incorrectly
changed to jump to the done label, which would try to use rfcomm
again to process pending commands.
To be sure that the AG reply correspond to the command sent, this
postpone the new command if previous reply (OK, ERROR or +CME) has
not yet been received.
The postponed command is sent on reception of the reply.
This allows implementing UI mechanisms to transfer the audio of a call
to the HF (pipewire) only when the user explicitly asks/allows it.
Normally, when a call is connected, the phone initiates a SCO connection
and the HF accepts it, transfering audio automatically. In order to
allow for user interaction, this patch enables the UI to set the RejectSCO
property to 'true' in order to automatically reject the SCO connection.
Later on, at the UI's discression, the audio may be reconnected by calling
the Activate() method, which sends AT+BCC to re-initialize the SCO channel.
A configuration file option is also added to configure the default value
of the RejectSCO property. By setting this to 'true' in the config file,
it is possible to implement rejecting the audio of a call that is already
active at the time the Bluetooth connection to the phone initializes.
This is useful for implementations that do hardware offloading of the
SCO audio channel and need to communicate state information to the
hardware (at least).
Start call id at 1 as for the index calls in HFP, and move this id
to spa_bt_telephony_[ag|call] so they can be used by CLCC to retrieve
the related call.
if enhanced call status is supported, send AT+CLCC on +CIEV events to
get the calls information.
The HF should declare the features supported before trying to send
related AT commands.
It should only send AT+CHLD related commands if the remote AG supports
them.
On some phones (at least), sending AT+CHLD=0 while there is no held
call returns an error. Make sure we don't do this to avoid returning
an error on D-Bus when in fact hangup_all actually succeeds.
This commit implements the dial, answer and hangup callbacks to manage
call when connected to HFP AG device.
This adds +CLIP support to be able to get remote party phone number.
