2019-02-10Add support for AVIRTMark Farrugia1-8/+17
Leverage the new AVIRT driver for a more secure, more dynamically configurable loopback sound driver. To use, replace the file smixer-4a-default.json with smixer-4a-avirt.json, at /usr/libexec/agl/smixer/etc The existing snd-aloop configuration is not broken by this change. The submodule libavirt is temporary, and will be transformed into a library. Change-Id: I827636656c109a7393ad77997e05069a2462ea46 Signed-off-by: Mark Farrugia <mark.farrugia@fiberdyne.com.au>

2018-12-22Implemented the bug cleanup at application exitStephane Desneux1-9/+15
Fixes most memory leaks in softmixer. The concept of 'transaction' for dynamic streams has been generalized to the objects created at startup. The cleanup is done via a handle set through a atexit() call. Also added a missing strdup in alsa-api-loop, that fixes a double free. Warning, the bluez-alsa PCM are not closed in this version. This is intentional due to a BUG in the bluealsa ioplug PCM, that crashes upon close (pthread_cancel is used to terminate the io_thread and things get very bad. I have a pending fix for that, relying on a cancellation pipe, but deeper testing must be done). As an effect, only one phone call can be made, else 4a needs to be restarted Change-Id: Idb84cafe15f17c0ef02fcc70296d541dc55a2dcf Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh> Signed-off-by: Stephane Desneux <stephane.desneux@iot.bzh>
2018-12-19Add support for bluetooth telephonyguppy_6.99.3guppy/6.99.36.99.3Thierry Bultel1-75/+250
This adds support for bluetooth telephony. A big rework in the softmixer internals has been mandatory, in order to support dynamic streams creation and deletions. Bluetooth telephony relies on the recent evolutions of bluez-alsa, the most important one being the support of HFP over Ofono. The softmixer opens PCM ioplugs provided by bluez-alsa. Bluetooth SCO needs 2 streams, one for listening and the other for talking. These streams are created upon requests sent by the hal-manager. The hal manager subscribes for bluez-alsa events and request the list of availalble transports. For each "attach" transaction verb, the softmixer maintains a list of the all created objects (sources, sinks, zones, ramps, streams, and more) Additionnally, it creates a new verb when the attach succeeds, that verb is typically something like "sco_XX:XX:XX:XX:XX:XX", and the only supported action at the present time is {"action":"remove"}, that performs all the cleanup of the registered objects.

2018-08-31Added bluez sound playback supportThierry Bultel1-5/+23
This adds sound playback for incoming sound from connected bluetooth devices. In this version, the softmixer relies on a modified bluez-alsa version (https://github.com/iotbzh/bluez-alsa), that provides an ioplug PCM bluezalsa connection proxy. The softmixer api has a new verb to dynamically set the device to listen to: afb-client-demo ws://localhost:1234/api?token=\uuid=123 smixer bluezalsa_dev '{"interface":"hci0", "device":"F6:32:15:2A:80:70", "profile":"a2dp"}' In this way it is possible to switch from a bluezalsa audio source to another without any further configuration. For now, only interface hci0 is supported. This commit also migrates the softmixer binding to API v3 Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2018-07-11stops the read/write loop when the stream is mutedThierry Bultel1-4/+8
when the stream is muted (due to the configuration, or due to a HAL request), the read/write loop is stopped. The benefit is that muting will work with capture devices that do not implement the mute in their driver. The inconvenient of stopping the read loop is that it has made appear an unexpected side-effect: the poll on capture does not trig for further incoming frames. The workaround is to completely close, then reopen and configure the capture PCM. Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
