ASoC: intel - fix the card names

2020-06-07T11:18:49+00:00

[ Upstream commit d745cc1ab65945b2d17ec9c5652f38299c054649 ]

Those strings are exposed to the user space as the
card name thus used in the GUIs. The common
standard is to avoid '_' here. The worst case
is 'sof-skl_hda_card' string.

ALSA: usb-audio: Quirks for Gigabyte TRX40 Aorus Master onboard audio

2020-06-03T06:21:24+00:00

[ Upstream commit 7f5ad9c9003425175f46c94df380e8c9e558cfb5 ]

Gigabyte TRX40 Aorus Master is equipped with two USB-audio devices,
a Realtek ALC1220-VB codec (USB ID 0414:a001) and an ESS SABRE9218 DAC
(USB ID 0414:a000).  The latter serves solely for the headphone output
on the front panel while the former serves for the rest I/Os (mostly
for the I/Os in the rear panel but also including the front mic).

Both chips do work more or less with the unmodified USB-audio driver,
but there are a few glitches.  The ALC1220-VB returns an error for an
inquiry to some jacks, as already seen on other TRX40-based mobos.
However this machine has a slightly incompatible configuration, hence
the existing mapping cannot be used as is.

Meanwhile the ESS chip seems working without any quirk.  But since
both audio devices don't provide any specific names, both cards appear
as "USB-Audio", and it's quite confusing for users.

This patch is an attempt to overcome those issues:

- The specific mapping table for ALC1220-VB is provided, reducing the
  non-working nodes and renaming the badly chosen controls.
  The connector map isn't needed here unlike other TRX40 quirks.

- For both USB IDs (0414:a000 and 0414:a001), provide specific card
  name strings, so that user-space can identify more easily; and more
  importantly, UCM profile can be applied to each.

ALSA: usb-audio: mixer: volume quirk for ESS Technology Asus USB DAC

2020-06-03T06:21:23+00:00

[ Upstream commit 4020d1ccbe55bdf67b31d718d2400506eaf4b43f ]

The Asus USB DAC is a USB type-C audio dongle for connecting to
the headset and headphone. The volume minimum value -23040 which
is 0xa600 in hexadecimal with the resolution value 1 indicates
this should be endianness issue caused by the firmware bug. Add
a volume quirk to fix the volume control problem.

Also fixes this warning:
  Warning! Unlikely big volume range (=23040), cval->res is probably wrong.
  [5] FU [Headset Capture Volume] ch = 1, val = -23040/0/1
  Warning! Unlikely big volume range (=23040), cval->res is probably wrong.

ALSA: hda/realtek - Add a model for Thinkpad T570 without DAC workaround

2020-06-03T06:21:23+00:00

[ Upstream commit 399c01aa49e548c82d40f8161915a5941dd3c60e ]

We fixed the regression of the speaker volume for some Thinkpad models
(e.g. T570) by the commit 54947cd64c1b ("ALSA: hda/realtek - Fix
speaker output regression on Thinkpad T570").  Essentially it fixes
the DAC / pin pairing by a static table.  It was confirmed and merged
to stable kernel later.

Now, interestingly, we got another regression report for the very same
model (T570) about the similar problem, and the commit above was the
culprit.  That is, by some reason, there are devices that prefer the
DAC1, and another device DAC2!

Unfortunately those have the same ID and we have no idea what can
differentiate, in this patch, a new fixup model "tpt470-dock-fix" is
provided, so that users with such a machine can apply it manually.
When model=tpt470-dock-fix option is passed to snd-hda-intel module,
it avoids the fixed DAC pairing and the DAC1 is assigned to the
speaker like the earlier versions.

ALSA: hwdep: fix a left shifting 1 by 31 UB bug

2020-06-03T06:21:22+00:00

[ Upstream commit fb8cd6481ffd126f35e9e146a0dcf0c4e8899f2e ]

The "info.index" variable can be 31 in "1 << info.index".
This might trigger an undefined behavior since 1 is signed.

Fix this by casting 1 to 1u just to be sure "1u << 31" is defined.

ALSA: usb-audio: add mapping for ASRock TRX40 Creator

2020-06-03T06:21:09+00:00

[ Upstream commit da7a8f1a8fc3e14c6dcc52b4098bddb8f20390be ]

This is another TRX40 based motherboard with ALC1220-VB USB-audio
that requires a static mapping table.

This motherboard also has a PCI device which advertises no codecs.  The
PCI ID is 1022:1487 and PCI SSID is 1022:d102.  As this is using the AMD
vendor ID, don't blacklist for now in case other boards have a working
audio device with the same ssid.

The Gigabyte X570 Aorus Xtreme motherboard with ALC1220 codec
requires a similar workaround for Clevo laptops to enforce the
DAC/mixer connection path. Set up a quirk entry for that.

ALSA: pcm: fix incorrect hw_base increase

2020-05-27T15:46:39+00:00

commit e7513c5786f8b33f0c107b3759e433bc6cbb2efa upstream.

There is a corner case that ALSA keeps increasing the hw_ptr but DMA
already stop working/updating the position for a long time.

In following log we can see the position returned from DMA driver does
not move at all but the hw_ptr got increased at some point of time so
snd_pcm_avail() will return a large number which seems to be a buffer
underrun event from user space program point of view. The program
thinks there is space in the buffer and fill more data.

[  418.510086] sound pcmC0D5p: pos 96 hw_ptr 96 appl_ptr 4096 avail 12368
[  418.510149] sound pcmC0D5p: pos 96 hw_ptr 96 appl_ptr 6910 avail 9554
...
[  418.681052] sound pcmC0D5p: pos 96 hw_ptr 96 appl_ptr 15102 avail 1362
[  418.681130] sound pcmC0D5p: pos 96 hw_ptr 96 appl_ptr 16464 avail 0
[  418.726515] sound pcmC0D5p: pos 96 hw_ptr 16464 appl_ptr 16464 avail 16368

This is because the hw_base will be increased by runtime->buffer_size
frames unconditionally if the hw_ptr is not updated for over half of
buffer time. As the hw_base increases, so does the hw_ptr increased
by the same number.

The avail value returned from snd_pcm_avail() could exceed the limit
(buffer_size) easily becase the hw_ptr itself got increased by same
buffer_size samples when the corner case happens. In following log,
the buffer_size is 16368 samples but the avail is 21810 samples so
CRAS server complains about it.

[  418.851755] sound pcmC0D5p: pos 96 hw_ptr 16464 appl_ptr 27390 avail 5442
[  418.926491] sound pcmC0D5p: pos 96 hw_ptr 32832 appl_ptr 27390 avail 21810

cras_server[1907]: pcm_avail returned frames larger than buf_size:
sof-glkda7219max: :0,5: 21810 > 16368

By updating runtime->hw_ptr_jiffies each time the HWSYNC is called,
the hw_base will keep the same when buffer stall happens at long as
the interval between each HWSYNC call is shorter than half of buffer
time.

Following is a log captured by a patched kernel. The hw_base/hw_ptr
value is fixed in this corner case and user space program should be
aware of the buffer stall and handle it.
