2018-09-10bluez-alsa: fixed the null device logicThierry Bultel1-2/+1
Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2018-09-07fixed crash upon misconfiguration of capture/playback devicesThierry Bultel6-16/+24
The null pcmplug case was not correctly handled in various places. Also fixed some typos in the log Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2018-09-07dmix: used device when in name of slaveThierry Bultel1-5/+27
When a sound card has multiple devices, it is invalid to set the slave name of the dmix as "hw:cardname" because alsa does not know which device to use. The fix consists in using the device number, when it is given. Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2018-08-31Added bluez sound playback supportThierry Bultel10-42/+254
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>

2018-07-20rework the sound capture & playback modelThierry Bultel4-254/+324
Now uses two threads for in the playing loop The first one reads from the capture device (ie, a phys. capture, or snd_aloop) and writes data to a circular buffer. The second one gets data from the circular buffer and outputs it to the playback. This model solves a lot of correlated timing bugs between read & write tasks. The read tasks only wakes up the write task when the buffer is 80% full. The buffer size big enough to hold 2 seconds of sound. The mute implementation has also been simplified, since it has been found out that it was possible to recover from an interrupted read, by calling snd_pcm_start additionnally to snd_pcm_prepare. Thus, the mute code consists in listening to an extra file descriptor in the read loop. Reading from that descriptor gives the mute or unmute command sent at higher level (in the PCM control event callback). When a 'mute' order is get, the capture sound fd is simply backup and replaced by '-1' in the set of the poll of the read task. When a 'unmute' order is get, the fd is simply restored. The start threshold is only computed for capture, and hardcoded to 1 for playback. This removes most of the remaining EPIPE on playback. The stop threshold has been removed. It had bad side effects on the amount of writeable data returned by snd_pcm_avail_update (was returning too small chunks) Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>

2018-07-17alsa-core-pcm: sets sw start & stop thresholdsThierry Bultel1-12/+90
Uses the same logic as 'aplay' to set the start & stop thresholds. With this fix, there are no more periodic EPIPE errors when writing to playback Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2018-07-11stops the read/write loop when the stream is mutedThierry Bultel8-107/+286
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>

2018-06-22pcm core: fixed spurious XRUN issuesThierry Bultel2-95/+257
This fixes the numerous XRUN issues seen on some cards. The trick is to set the buffer_size & period size in hw parameters. These ones are calculated from an expected maximum latency. Also, the writei is done in a loop to be robust to overruns and partial writes. Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
