2019-02-18intel-upsquared: fixed the bluetooth SCO with an optional micsandbox/jsmoeller/testsandboxThierry Bultel1-11/+23
Fixed the bogus capture setup, HDMI cannot be used for that. See comments about changes of the minnow board for more details. Change-Id: Ia845437aade06d5994e7b86e3f73dca1ac0c197a Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2019-02-18intel-minnow: fixes the bluetooth SCO with a optional mic.Thierry Bultel1-13/+26
This commit introduces several things. The original need was to fix the bluetooth SCO that was not working on the minnow board. The reason was that this board only has audio output through HDMI, but no input, thus the "talk to bluetooth" stream could not be created. So: 1) Introduces support for an optional USB mono microphone When the mic is not detected, only the "listen" stream is created (so that it is possible for the user to listen to his/her audio messages). So in the "capture" section, a new boolean "optional" parameter is added. 2) mono to stereo conversion is not something straightforward It requires the usage of a dedicated zone, so that mono channel is duplicated to both the right and left channel. This is why a 'front-seats-mono' zone is added to the json file. 3) CPU load and write 'quirk' After having faced problems of heavy CPU load and write errors on the playback device, the way sound output is done in the softmixer has been reworked, to conform to ALSA examples. It relies on a classic "'poll" followed by a call to "snd_pcm_poll_descriptors_revents" that demangles the events. On the minnow board, that does not work. Spurious null events, that should be ignored, -must- be taken in account on the minnow PCH device, else next writes often issue an EPIPE error, leading to clipped sound. Thus here a quirk section is added to the json file, and the only quirk is QUIRK_BOGUS_POLL_REVENTS_DEMANGLING. In the softmixer, when that quirk is set on a device, null events are no longer ignored. This commit must be taken together with: - The fix for PCM ioplug in bluez-alsa - The needed changes in softmixer Change-Id: Ide1605e5480d773e2681ff762e3ecf4c84718fde Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>

HAL Manager is now more picky and refuses to load unknown controls. In the specific case of minnowboard, the declared control for master volume is wrong. This patch removes the master volume control from halmap section.

2018-12-20bluetooth audio: uses the new bluealsa pluginguppy_6.99.3guppy/6.99.36.99.3Thierry Bultel12-81/+157
Updated all the HALs to use the new bluealsa plugin, that dynamically creates and deletes audio streams upon bluetooth connections from mobile phones. The plugin parameters consists in 2 sections. The "sco" section is the place for voice calls. It is where to specify which microphone to use (this one must be declared in the captures devices), and to what zone to do the playback (that zone must be defined, too) The "a2dp" is for music playback. The only needed paramter is a playback zone. It can be different fromt the one used by SCO. Additionnally, both SCO and A2DP have a "delayms" parameter which is the size in milliseconds of the copy buffer for the audio stream. The values set in this commit are good enough for a demo, but can we optimized in the future.
