alsa-lib

Core

- Release v1.2.1.2 - local.h: remove sound/asoundef.h dependency - asoundef.h: add CEA861_AUDIO_INFOFRAME defines

Control API

- control: ctlparse - accept enum values in or ""

PCM API

- pcm_file: fix pipe stall when pclose() is called too early

BugLink: https://github.com/alsa-project/alsa-lib/issues/14

Topology API

- include/sound: sync with the kernel v5.4

Use Case Manager API

- ucm: add support for ControlEnum in ControlExists condition

Condition {
  Type ControlExists
  Control "name='Capture Input'"
  ControlEnum "Headphone Mic"
}

The result is true if the control exists, it is the enumerated
type and has the item with the ControlEnum text (name).

- ucm: conditions - fix the wrong string/substring match - use-case: add priority values from pulseaudio - use-case: improve comment for mixer elements - ucm: rename mixer element identifiers

To my knowledge, no software is using the mixer element identifiers.
Rename them to be more consistent with the mixer API and add
Master element identifier and type.

- ucm: fix the cdev initialization sequence

The default values must be set before the defaults
UCM sequence is executed.

- ucm: remove the new-line for uc_error() calls - ucm: use-case.h - add <alsa/asoundlib.h> include

It is required for snd_ctl_elem_id_t and snd_mixer_selem_id_t.

- ucm: add ${CardDriver} substitution - ucm: implement ${sys:sysfs/path} substitution

Example:

Condition {
        Type String
        String1 "${sys:class/dmi/id/board_vendor}"
        String2 "LENOVO"
}

Kernel Headers

- include/sound/Makefile.am: remove asoundef.h - local.h: remove sound/asoundef.h dependency - include/sound: sync with the kernel v5.4

Utils

- alsa.m4: Fix the detection of topology library availability

The header file alsa/topology.h is mandatory and needs to be checked,
too.
