Geoffrey D. Bennett 265d1a90e4 ALSA: usb-audio: scarlett2: Improve driver startup messages
Add separate init function to call the existing controls_create
function so a custom error can be displayed if initialisation fails.

Use info level instead of error for notifications.

Display the VID/PID so device_setup is targeted to the right device.

Display "enabled" message to easily confirm that the driver is loaded.

Takashi Iwai 05ca447630 ALSA: line6: Fix racy initialization of LINE6 MIDI
The initialization of MIDI devices that are found on some LINE6
drivers are currently done in a racy way; namely, the MIDI buffer
instance is allocated and initialized in each private_init callback
while the communication with the interface is already started via
line6_init_cap_control() call before that point.  This may lead to
Oops in line6_data_received() when a spurious event is received, as
reported by syzkaller.

This patch moves the MIDI initialization to line6_init_cap_control()
as well instead of the too-lately-called private_init for avoiding the
race.  Also this reduces slightly more lines, so it's a win-win
change.

Takashi Iwai 988cc17552 ALSA: usb-audio: Fix implicit sync clearance at stopping stream
The recent endpoint management change for implicit feedback mode added
a clearance of ep->sync_sink (formerly ep->sync_slave) pointer at
snd_usb_endpoint_stop() to assure no leftover for the feedback from
the already stopped capture stream.  This turned out to cause a
regression, however, when full-duplex streams were running and only a
capture was stopped.  Because of the above clearance of ep->sync_sink
pointer, no more feedback is done, hence the playback will stall.

This patch fixes the ep->sync_sink clearance to be done only after all
endpoints are released, for addressing the regression.

Takashi Iwai 316791b556 ALSA: usb-audio: Generic application of implicit fb to Roland/BOSS devices
Through the examinations and experiments with lots of Roland and BOSS
USB-audio devices, we found out that the recently introduced
full-duplex operations with the implicit feedback mode work fine for
quite a few devices, while the others need only the capture-side quirk
to enforce the full-duplex mode.  The recent commit d86f43b17e
("ALSA: usb-audio: Add support for many Roland devices' implicit
feedback quirks") tried to add such quirk entries manually in the
lists, but this turned out to be too many and error-prone, hence it
was reverted again.

This patch is another attempt to cover those missing Roland/BOSS
devices but in a more generic way.  It matches the devices with the
vendor ID 0x0582, and checks whether they are with both ASYNC sync
types or ASYNC is only for capture device.  In the former case, it's
the device with the implicit feedback mode, and applies accordingly.
In both cases, the capture stream requires always the full-duplex
mode, and we apply the known capture quirk for that, too.

Basically the already existing BOSS device quirk entries become
redundant after this generic matching, so those are removed.  Although
the capture_implicit_fb_quirks[] table became empty and superfluous, I
keep it for now, so that people can put a special device easily at any
time later again.

This reverts commit d86f43b17e ("ALSA: usb-audio: Add support for

It turned out that many quirk entries there don't contain the proper
EP values and/or the quirk types, which lead to the broken
operations.

As we're going to cover all Roland/BOSS devices in a more generic way
rather the explicit lists, let's revert the previous additions at
first.

Takashi Iwai fd9db1058c ALSA: usb-audio: Re-apply implicit feedback mode to Pioneer devices
Pioneer devices are supposed to be working with the implicit feedback
mode, but so far the attempt to apply the implicit feedback caused
issues, hence we explicitly skipped the implicit feedback mode for
them.  Recently, Geraldo discovered that the device actually works if
you skip the generic matching of the sync EPs for the capture stream.
That is, we should apply the implicit feedback setup for the playback
like other similar devices, while we need to return 1 from
audioformat_capture_quirk() so that no further matching will be done.

And, later on, Olivia reported later that the fiddling with the
capture quirk alone doesn't suffice for the test with speaker-test
program.  This seems to be a similar case like the recently fixed BOSS
devices.  Indeed, the problem could be addressed by setting
playback_first flag, which indicates that the playback URBs have to be
sent out at first even in the implicit feedback mode.

This patch implements the application of the implicit feedback to
Pioneer devices as described in the above.  The former
skip_pioneer_sync_ep() was dropped, and instead we provide
is_pioneer_implicit_fb() to check the Pioneer devices that need the
implicit feedback.  In the audioformat_implicit_fb_quirk(), simply
apply the implicit fb for playback and set chip->playback_first flag
if matching, and in audioformat_capture_quirk()(), it returns 1 for
skipping the generic EP sync handling.

Takashi Iwai ebe8dc5afb ALSA: usb-audio: Apply implicit feedback mode for BOSS devices
During the recent rewrite of the implicit feedback support, we've
tested to apply the implicit fb on BOSS devices, but it failed, as the
capture stream didn't start without the playback.  As the end result,
it got another type of quirk for tying both streams but starts
playback always (commit 6234fdc1ce "ALSA: usb-audio: Quirk for BOSS
GT-001").

Meanwhile, Mike Oliphant has tested the real implicit feedback mode
for the playback again with the latest code, and found out that it
actually works if the initial feedback sync is skipped; that is, on
those BOSS devices, the playback stream has to be started at first
without waiting for the capture URB completions.  Otherwise it gets
stuck.  In the rest operations after the capture stream processed, we
can take them as the implicit feedback source.

This patch is an attempt to improve the support for BOSS devices with
the implicit feedback mode in the way described above.  It adds a new
flag to snd_usb_audio, playback_first, indicating that the playback
stream starts without sync with the initial capture completion.  This
flag is set in the quirk table with the new IMPLICIT_FB_BOTH type.

Takashi Iwai d2e8f64125 ALSA: usb-audio: Explicitly set up the clock selector
In the current code, we have some assumption that the audio clock
selector has been set up implicitly and don't want to touch it unless
it's really needed for the fallback autoclock setup.  This works for
most devices but some seem having a problem.  Partially this was
covered for the devices with a single connector at the initialization
phase (commit 086b957cc1 "ALSA: usb-audio: Skip the clock selector
inquiry for single connections"), but also there are cases where the
wrong clock set up is kept silently.  The latter seems to be the cause
of the noises on Behringer devices.

In this patch, we explicitly set up the audio clock selector whenever
the appropriate node is found.

Takashi Iwai 5b1ed7df01 ALSA: control - add generic LED API
This patchset tries to resolve the diversity in the audio LED
 control among the ALSA drivers. A new control layer registration
 is introduced which allows to run additional operations on
 top of the elementary ALSA sound controls.
 
 A new control access group (three bits in the access flags)
 was introduced to carry the LED group information for
 the sound controls. The low-level sound drivers can just
 mark those controls using this access group. This information
 is not exported to the user space, but user space can
 manage the LED sound control associations through sysfs
 (last patch) per Mark's request. It makes things fully
 configurable in the kernel and user space (UCM).
 
 The actual state ('route') evaluation is really easy
 (the minimal value check for all channels / controls / cards).
 If there's more complicated logic for a given hardware,
 the card driver may eventually export a new read-only
 sound control for the LED group and do the logic itself.
 
 The new LED trigger control code is completely separated
 and possibly optional (there's no symbol dependency).
 The full code separation allows eventually to move this
 LED trigger control to the user space in future.
 Actually it replaces the already present functionality
 in the kernel space (HDA drivers) and allows a quick adoption
 for the recent hardware (ASoC codecs including SoundWire).
 
 snd_ctl_led            24576  0
 
 The sound driver implementation is really easy:
 
 1) call snd_ctl_led_request() when control LED layer should be
    automatically activated
    / it calls module_request("snd-ctl-led") on demand /
 2) mark all related kcontrols with
         SNDRV_CTL_ELEM_ACCESS_SPK_LED or
         SNDRV_CTL_ELEM_ACCESS_MIC_LED

sound control for the LED group and do the logic itself.

The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).

snd_ctl_led            24576  0

The sound driver implementation is really easy:

1) call snd_ctl_led_request() when control LED layer should be
   automatically activated
   / it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
        SNDRV_CTL_ELEM_ACCESS_SPK_LED or
        SNDRV_CTL_ELEM_ACCESS_MIC_LED

Ikjoon Jang 625bd5a616 ALSA: usb-audio: Apply sample rate quirk to Logitech Connect
Logitech ConferenceCam Connect is a compound USB device with UVC and
UAC. Not 100% reproducible but sometimes it keeps responding STALL to
every control transfer once it receives get_freq request.

This patch adds 046d:0x084c to a snd_usb_get_sample_rate_quirk list.

Kai-Heng Feng 44609fc01f ALSA: usb-audio: Check connector value on resume
Rear Mic on Lenovo P620 cannot record after S3, despite that there's no
error and the other two functions of the USB audio, Line In and Line
Out, work just fine.

The mic starts to work again after running userspace app like "alsactl
store". Following the lead, the evidence shows that as soon as connector
status is queried, the mic can work again.

So also check connector value on resume to "wake up" the USB audio to
make it functional.

This can be device specific, however I think this generic approach may
benefit more than one device.

Now the resume callback checks connector, and a new callback,
reset_resume, to also restore switches and volumes.

The shifting of the u8 integer device by 24 bits to the left will
be promoted to a 32 bit signed int and then sign-extended to a
64 bit unsigned long. In the event that the top bit of device is
set then all then all the upper 32 bits of the unsigned long will
end up as also being set because of the sign-extension. Fix this
by casting device to an unsigned long before the shift.

Other Plantronics headset models seem requiring the same workaround as

Note that the problem didn't surface before 5.11 just with luck.
Since 5.11 got a big code rewrite about the stream handling, the
parameter setup procedure has changed, and this seemed triggering the
problem more often.

I overlooked the issue because when I was working on the said commit,
only the front audio is tested. Apology for that.

Changing supports_autosuspend in driver is too late for disabling
autosuspend, because it was already used by USB probe routine, so it can
break the balance on the following code that depends on
supports_autosuspend.

Fix it by using usb_disable_autosuspend() helper, and balance the
suspend count in disconnect callback.

Takashi Iwai 5f5e6a3e8b ALSA: usb-audio: Allow modifying parameters with succeeding hw_params calls
The recent fix for the hw constraints for implicit feedback streams
via commit e4ea77f8e5 ("ALSA: usb-audio: Always apply the hw
constraints for implicit fb sync") added the check of the matching
endpoints and whether those EPs are already opened.  This is needed
and correct, per se, even for the normal streams without the implicit
feedback, as the endpoint setup is exclusive.

However, it's reported that there seem applications that behave in
unexpected ways to update the hw_params without clearing the previous
setup via hw_free, and those hit a problem now: then hw_params is
called with still the previous EP setup kept, hence it's restricted
with the previous own setup.  Although the obvious fix is to call
snd_pcm_hw_free() API in the application side, it's a kind of
unwelcome change.

This patch tries to ease the situation: in the endpoint check, we add
a couple of more conditions and now skip the endpoint that is being
used only by the stream in question itself.  That is, in addition to
the presence check of ep (ep->cur_audiofmt is non-NULL), when the
following conditions are met, we skip such an ep:
- ep->opened == 1, and
- ep->cur_audiofmt == subs->cur_audiofmt.

subs->cur_audiofmt is non-NULL only if it's a re-setup of hw_params,
and ep->cur_audiofmt points to the currently set up parameters.  So if
those match, it must be this stream itself.

Takashi Iwai 21cba9c535 ALSA: usb-audio: Drop bogus dB range in too low level
Some USB audio firmware seem to report broken dB values for the volume
controls, and this screws up applications like PulseAudio who blindly
trusts the given data.  For example, Edifier G2000 reports a PCM
volume from -128dB to -127dB, and this results in barely inaudible
sound.

This patch adds a sort of sanity check at parsing the dB values in
USB-audio driver and disables the dB reporting if the range looks
bogus.  Here, we assume -96dB as the bottom line of the max dB.

Note that, if one can figure out that proper dB range later, it can be
patched in the mixer maps.

Takashi Iwai dcf269b3f7 ALSA: usb-audio: Don't abort even if the clock rate differs
The commit 93db51d06b ("ALSA: usb-audio: Check valid altsetting at
parsing rates for UAC2/3") changed the behavior of the function
set_sample_rate_v2v3() slightly to treat the inconsistent sample rate
as an error.  It was done by assumption that the sample rate
validation should have been done at the parser phase as implemented in
that patch.  But the validation is later selectively enabled only for
certain devices as it causes a regression (the commit fe773b8711
"ALSA: usb-audio: workaround for iface reset issue"), and now the
inconsistency surfaced as a fatal error while it worked in the past as
is, as reported for FiiO M3K DAC.

For recovering from the regression, change set_sample_rate_v2v3()
again to ignore the sample rate difference as non-error.

Takashi Iwai 257d2d7e9e ALSA: usb-audio: Don't avoid stopping the stream at disconnection
In the later patch, we're going to issue the PCM sync_stop calls at
disconnection.  But currently the USB-audio driver can't handle it
because it has a check of shutdown flag for stopping the URBs.  This
is basically superfluous (the stopping URBs are safe at disconnection
state), so let's drop the check.
