Detailed changelog between 1.2.15.2 and 1.2.15.3 releases

Changelog between 1.2.15.2 and 1.2.15.3 releases

alsa-lib

Core

- Release v1.2.15.3

Sequencer API

- seq: return back old snd_seq_drain_output behaviour for -EAGAIN 

It seems that many applications did not follow the documentation
including pyalsa sequencer module, thus return the previous
behaviour and correct documentation.

Closes: https://github.com/alsa-project/alsa-lib/issues/493

Configuration

- HDA-analog: Fix the phantom jack detection if block 

The hpvol assignment should depend on speaker/line out detection.

- HDA-analog: Use phantom jacks to determine the device for single output 

Improve previous commit (change) to determine the output type (device).

- HDA-analog: Add output when only 'Master Playback' control exists 

There is a case when only one output is present (e.g. internal
speakers or hp output). In this case, the driver offers only
master volume controls.

Add also more related cleanups for the line out and SOF HDA configs.

- sof-hda-dsp: remove some debug lines 

Since 1.2.15, there is a better way to see the variable traces, e.g.:

  LIBASOUND_DEBUG=trace alsaucm -c hw:sofhdadsp dump text

- sof-hda-dsp: Headphone output is optional 

Align changes with commit c8b5541.

- ucm2: HDA: Fix headphone detection 

It appears that there are devices with just switches (no
volume controls). Test presence of 'Headphone Playback Switch'
control.
