There are a number of mechanisms, including the userspace accessible
timestamp and buffer availability ioctl()s, which allow us to trigger
a timestamp update on a stream before it has been configured. Since
drivers might rely on stream configuration for reporting of pcm_io_frames,
including potentially doing a division by the number of channels, and
these operations are not meaningful for an unconfigured stream reject
attempts to read timestamps before any configuration is done.

The ISA ES1688 driver still carries a disabled suspend/resume block in
its isa_driver definition, while the same file already provides minimal
power-management handling for the PnP ES968 path.
Add ISA-specific PM callbacks and factor the existing ES1688 suspend and
resume sequence into common card-level helpers shared by both probe
paths. Suspend moves the card to D3hot. Resume reinitializes the chip
with snd_es1688_reset() and restores the card to D0, propagating reset
failures to the caller.
This wires up power-management callbacks for the ISA path and keeps the
PM handling consistent between the ISA and PnP probe paths.

The i2sbus PCM code uses pi->active to constrain the sibling stream to
an already prepared duplex format and rate in i2sbus_pcm_open().
That state is set from i2sbus_pcm_prepare(), but the current code only
clears it on close. As a result, the sibling stream can inherit stale
constraints after the prepared state has been torn down.
Clear pi->active when hw_params() or hw_free() tears down the prepared
state, and set it again only after prepare succeeds.
Replace the stale FIXME in the duplex constraint comment with a description
of the current driver behavior: i2sbus still programs a single shared
transport configuration for both directions, so mixed formats are not
supported in duplex mode.

The Lenovo Yoga Pro 7 14IMH9 (DMI: 83E2) shares PCI SSID 17aa:3847
with the Legion 7 16ACHG6, but has a different codec subsystem ID
(17aa:38cf). The existing SND_PCI_QUIRK for 17aa:3847 applies
ALC287_FIXUP_LEGION_16ACHG6, which attempts to initialize an external
I2C amplifier (CLSA0100) that is not present on the Yoga Pro 7 14IMH9.
As a result, pin 0x17 (bass speakers) is connected to DAC 0x06 which
has no volume control, making hardware volume adjustment completely
non-functional. Audio is either silent or at maximum volume regardless
of the slider position.
Add a HDA_CODEC_QUIRK entry using the codec subsystem ID (17aa:38cf)
to correctly identify the Yoga Pro 7 14IMH9 and apply
ALC287_FIXUP_YOGA9_14IMH9_BASS_SPK_PIN, which redirects pin 0x17 to
DAC 0x02 and restores proper volume control. The existing Legion entry
is preserved unchanged.
This follows the same pattern used for 17aa:386e, where Legion Y9000X
and Yoga Pro 7 14ARP8 share a PCI SSID but are distinguished via
HDA_CODEC_QUIRK.

The recent refactoring of xfi driver changed the assignment of
atc->daios[] at atc_get_resources(); now it loops over all enum
DAIOTYP entries while it looped formerly only a part of them.
The problem is that the last entry, SPDIF1, is a special type that
is used only for hw20k1 CTSB073X model (as a replacement of SPDIFIO),
and there is no corresponding definition for hw20k2. Due to the lack
of the info, it caused a kernel crash on hw20k2, which was already
worked around by the commit b045ab3dff ("ALSA: ctxfi: Fix missing

This patch addresses the root cause of the regression above properly,
simply by skipping the incorrect SPDIF1 type in the parser loop.

The loop creates a whitespace-stripped copy of the card shortname
where `len < sizeof(card->id)` is used for the bounds check. Since
sizeof(card->id) is 16 and the local id buffer is also 16 bytes,
writing 16 non-space characters fills the entire buffer,
overwriting the terminating nullbyte.
When this non-null-terminated string is later passed to
snd_card_set_id() -> copy_valid_id_string(), the function scans
forward with `while (*nid && ...)` and reads past the end of the
stack buffer, reading the contents of the stack.
A USB device with a product name containing many non-ASCII, non-space
characters (e.g. multibyte UTF-8) will reliably trigger this as follows:
BUG: KASAN: stack-out-of-bounds in copy_valid_id_string
sound/core/init.c:696 [inline]
BUG: KASAN: stack-out-of-bounds in snd_card_set_id_no_lock+0x698/0x74c
sound/core/init.c:718
The off-by-one has been present since commit bafeee5b1f ("ALSA:
snd_usb_caiaq: give better shortname") from June 2009 (v2.6.31-rc1),
which first introduced this whitespace-stripping loop. The original
code never accounted for the null terminator when bounding the copy.
Fix this by changing the loop bound to `sizeof(card->id) - 1`,
ensuring at least one byte remains as the null terminator.

Commit ab949d5196 ("ALSA: hda - Fix deadlock of controller device
lock at unbinding") added a temporary device_unlock()/device_lock()
pair around probe-work cancellation to avoid a deadlock between
controller unbind and codec probe.
That deadlock depended on the driver core taking both a device lock and
its parent lock during bind and unbind. Since commit 8c97a46af0
("driver core: hold dev's parent lock when needed") and follow-up
fixes, the parent lock is only taken when bus->need_parent_lock is set.
The HDA bus does not set that flag, so codec binding no longer locks
the controller device as the codec's parent.
Keep cancel_delayed_work_sync(), since the async probe/remove race
still needs to be serialized, but drop the stale unlock/relock
workaround and its outdated FIXME comment. Keeping it around only
opens an unnecessary unlocked window inside azx_remove().

writes past the end of hpi_ctl->name.
The generated control name is used as the ALSA control element key, so
blindly truncating it is not sufficient. Switch the formatting to

snd_pcm_suspend_all() walks all PCM substreams and uses a lockless
runtime check to skip closed streams. It then calls snd_pcm_suspend()
for each remaining substream and finally runs snd_pcm_sync_stop() in a
second pass.
The runtime lifetime is still controlled by pcm->open_mutex in the
open/release path. That means a concurrent close can clear or free
substream->runtime after the initial check in snd_pcm_suspend_all(),
leaving the later suspend or sync-stop path to dereference a stale or
NULL runtime pointer.
Serialize snd_pcm_suspend_all() with pcm->open_mutex so the runtime
pointer stays stable across both loops. This matches the existing PCM
runtime lifetime rule already used by other core paths that access
substream->runtime outside the stream lock.

snd_usbmidi_standard_output() iterates output ports in ascending order
and drains each active port until the URB is full. On interfaces where
multiple USB-MIDI cables share one endpoint, sustained traffic on a
lower-numbered port can consume every refill before higher-numbered
ports are even examined.
That behavior dates back to the original implementation and still
applies with the current multi-URB output path. snd_usbmidi_do_output()
can refill several idle URBs in one pass, but each refill restarts the
scan at port 0, so a busy lower-numbered port can keep higher-numbered
ports from making progress at all.
Use ep->current_port as the starting point of the scan and advance it
after each URB fill. This keeps the existing packet formatting and
per-port state handling intact while preventing persistent starvation of
higher-numbered ports.

snd_pcm_ioctl_sync_ptr_x32() still handles incoming appl_ptr updates
differently from the other SYNC_PTR paths. The native handler and the
32-bit compat handler both pass appl_ptr through pcm_lib_apply_appl_ptr(),
but the x32 handler still writes control->appl_ptr directly.
That direct assignment skips the common appl_ptr validation against
runtime->boundary and also bypasses the substream ack() callback.
This makes the x32 ioctl path behave differently from the native and
compat32 cases, and it can miss the driver notification that explicit
appl_ptr synchronization relies on.
Use pcm_lib_apply_appl_ptr() for x32 too, so appl_ptr updates are
validated consistently and drivers relying on ack() notifications
see the same behavior.

The timer_f.utimer test hard-fails with ASSERT_EQ when
SNDRV_TIMER_IOCTL_CREATE returns -1 on kernels without
CONFIG_SND_UTIMER. This causes the entire alsa kselftest suite to
report a failure rather than skipping the unsupported test.
When CONFIG_SND_UTIMER is not enabled, the ioctl is not recognised and
the kernel returns -ENOTTY. If the timer device or subdevice does not
exist, -ENXIO is returned. Skip the test in both cases, but still fail
on any other unexpected error.

commit 30b3211aa2 ("ALSA: hda/intel: Add MSI X870E Tomahawk
to denylist") was added to silence a warning, but this effectively
reintroduced commit df42ee7e22 ("ALSA: hda: Add ASRock
X670E Taichi to denylist") which was already reported to cause
problems and reverted in commit ee8f161359 ("Revert "ALSA: hda:
Add ASRock X670E Taichi to denylist"")
Revert it yet again.
