      ALSA: bebob: improve signal mode detection for clock source · 5a668812
      由 Takashi Sakamoto 提交于 
      With BeBoB version 3, current ALSA BeBoB driver detects the type of
current clock signal source wrongly. This is due to a lack of proper
implementation to parse the information.

This commit renews the parser. As a result, this driver detects
SYT-Match clock signal, thus it can start streams with two modes;
SYT-Match mode and the others. SYT-Match mode will be supported in future
commits.

There's a constrain about detected internal/external clock source.
When detecting external clock source, this driver allows userspace
applications to use current sampling rate only. This is due to consider
abour synchronization to external clock sources such as S/PDIF, ADAT or
word-clock.

According to several information from some devices, I guesss that the
internal clock of most devices synchronize to IEEE 1394 cycle start
packet. In this case, by a usual way, it's detect as 'Sync type
of output Music Sub-Unit' connected to 'Sync type of PCR output Unit
(oPCR)', and this driver judges it as internal clock. Therefore,
userspace applications is allowed to request arbitrary supported sampling
rates.

On the other hand, several devices based on BeBoB version 3 have
additional internal clock. In this case, by a usual way, it's detect as
'Sync/Additional type of External input Unit'. Unfortunately, there's no
way to distinguish this sync type from the other external clock sources
such as word-clock. In this case, this driver handles it as external and
userspace applications is forced to use current sampling rate.

I note that when the source of clock is detected as 'Isochronous stream
type of input PCR[0]', it's under 'SYT-Match' mode. In this mode, the
synchronization clock is generated according to SYT-series in received
packets. In this case, this driver generates the series by myself. I
experienced this mode often make the device silent suddenly during
playbacking. This means that the mode is easy to lost synchronization.

      ALSA: hda - Fix audio crackles on Dell Latitude E7x40 · 8b99aba7
      由 Takashi Iwai 提交于 
      We still got a report that the audio crackles and noises occur with
the recent 4.1 kernels on Dell machines.  These machines seem to need
similar workarounds that have been applied to the recent Dell XPS 13
models.  Since the codec of these machines (Dell Latitute E7240 and
E7440) is different from XPS 13's one, we need a new fixup entry.

Also, it was confirmed that the previous workaround to disable the
widget power-save (commit [219f47e4: ALSA: hda - Disable widget
power-saving for ALC292 & co]) is no longer needed after this fix.
So, this patch includes the partial revert of the commit, too.

      ALSA: hda - adding a DAC/pin preference map for a HP Envy TS machine · 6ab42ff4
      由 Hui Wang 提交于 
      On a HP Envy TouchSmart laptop, there are 2 speakers (main speaker
and subwoofer speaker), 1 headphone and 2 DACs, without this fixup,
the headphone will be assigned to a DAC and the 2 speakers will be
assigned to another DAC, this assignment makes the surround-2.1
channels invalid.

To fix it, here using a DAC/pin preference map to bind the main
speaker to 1 DAC and the subwoofer speaker will be assigned to another
DAC.

      snd_hdac_link_power() has to be called after unregistering the codec

the refcount goes under zero, triggering a warning like:

      Now we have the bus and controller code added to find and initialize
the extended capabilities. Now we need to use them in stream code to
decouple stream, manage links etc

So this patch adds the stream handling code for extended capabilities

      ALSA: hda - Re-add the lost fake mute support · a686ec4c
      由 Takashi Iwai 提交于 
      Yet another regression by the transition to regmap cache; for better
usability, we had the fake mute control using the zero amp value for
Conexant codecs, and this was forgotten in the new hda core code.

Since the bits 4-7 are unused for the amp registers (as we follow the
syntax of AMP_GET verb), the bit 4 is now used to indicate the fake
mute.  For setting this flag, snd_hda_codec_amp_update() becomes a
function from a simple macro.  The bonus is that it gained a proper
function description.

      ALSA: hda - Continue probing even if i915 binding fails · bf06848b
      由 Takashi Iwai 提交于 
      Currently snd-hda-intel driver aborts the probing of Intel HD-audio
controller with i915 power well management when binding with i915
driver via hda_i915_init() fails.  This is no big problem for Haswell
and Broadwell where the HD-audio controllers are dedicated to
HDMI/DP, thus i915 link is mandatory.  However, Skylake, Baytrail and
Braswell have only one controller and both HDMI/DP and analog codecs
share the same bus.  Thus, even if HDMI/DP isn't usable, we should
keep the controller working for other codecs.

For fixing this, this patch simply allows continuing the probing even
if hda_i915_init() call fails.  This may leave stale sound components
for HDMI/DP devices that are unbound with graphics.  We could abort
the probing selectively, but from the code simplicity POV, it's better
to continue in all cases.
