ALSA: hda: Honor subformat when querying PCMs

2023-11-27T16:24:27+00:00

Update mechanism for querying supported PCMs to allow for granular
format selection when container size is 32 bits. Currently always the
highest bit depth is selected, regardless of how many actual formats
codec in question supports.

ASoC: Intel: Skylake: Use global PCI match macro

2023-07-18T12:22:19+00:00

Instead of using local macro to match PCI device, use global one. As
Apollolake is Broxton-P successor that made it to the market, be precise
and use APL shortcut. IS_CFL() macro is dropped as it is unused.

ALSA: hda: Fix the control element identification for multiple codecs

2023-02-03T16:19:20+00:00

Some motherboards have multiple HDA codecs connected to the serial bus.
The current code may create multiple mixer controls with the almost
identical identification.

The current code use id.device field from the control element structure
to store the codec address to avoid such clashes for multiple codecs.
Unfortunately, the user space do not handle this correctly. For mixer
controls, only name and index are used for the identifiers.

This patch fixes this problem to compose the index using the codec
address as an offset in case, when the control already exists. It is
really unlikely that one codec will create 10 similar controls.

This patch adds new kernel module parameter 'ctl_dev_id' to allow
select the old behaviour, too. The CONFIG_SND_HDA_CTL_DEV_ID Kconfig
option sets the default value.

ALSA: hda/hdmi: fix stream-id config keep-alive for rt suspend

2022-12-09T11:06:15+00:00

When the new style KAE keep-alive implementation is used on compatible
Intel hardware, the clocks are maintained when codec is in D3. The
generic code in hda_cleanup_all_streams() can however interfere with
generation of audio samples in this mode, by setting the stream and
channel ids to zero.

To get full benefit of the keepalive, set the new
no_stream_clean_at_suspend quirk bit on affected Intel hardware. When
this bit is set, stream cleanup is skipped in hda_call_codec_suspend().

Special handling is needed for the case when system goes to suspend. The
stream id programming can be lost in this case. This will also cause
codec->cvt_setups to be out of sync. Handle this by implementing custom
suspend/resume handlers. If keep-alive is active for any converter, set
the quirk flags no_stream_clean_at_suspend and forced_resume. Upon
resume, keepalive programming is restored if needed.

ALSA: hda/hdmi: Use only dynamic PCM device allocation

2022-09-22T11:58:16+00:00

Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM
device mapping is obsolete nowadays. The maximum number of the simultaneously
usable PCM devices is equal to the HDMI codec converters.

Remove the extra PCM devices (beyond the detected converters) and force
the use of the dynamic PCM device allocation. The legacy code is removed.

I believe that all HDMI codecs have the jack sensing feature. Move the check
to the codec probe function and print a warning, if a codec without this
feature is detected.

There are no users for snd_hdac_ext_bus_device_init() and
snd_hdac_ext_bus_device_exit().

While at it, remove hdac_to_hda_priv() too for the exact same reason.

ALSA: hda: Skip event processing for unregistered codecs

2022-07-15T14:26:50+00:00

When codec is unbound but not yet removed, in the eyes of
snd_hdac_bus_process_unsol_events() it is still a valid target to
delegate work to. Such behaviour may lead to use-after-free errors.
Address by verifying if codec is actually registered.

ALSA: hda: Jack detection poll in suspend state

2022-04-12T09:34:17+00:00

HDA Jack detection logic doesn't work when the HDACODEC
in runtime suspended state as unsol event won't be triggered
during D3 state. As pulseaudio server in userspace rely on the
jack mixer control status to show the audio devices in gui and
any display sink device hotplug event during D3 state will never
updates the jack status which will result in no audio device option
available in userspace settings.

The possible option available to resolve this issue is to run Jack
polling worker thread even after codec suspend state. The choice can
be made based on compromise between power saving or Jack detection in
suspend state.

With few changes, snd_hda_codec_register() and its
unregister-counterpart can be re-used by ASoC drivers. While at it,

Due to ALSA-device vs ASoC-component organization differences, new
'snddev_managed' argument is specified allowing for better control over
codec registration process.
