ALSA: pcxhr: Fix missing mutex unlock

2016-04-21T15:37:54+00:00

The commit [9bef72bdb26e: ALSA: pcxhr: Use nonatomic PCM ops]
converted to non-atomic PCM ops, but shamelessly with an unbalanced
mutex locking, which leads to the hangup easily.  Fix it.

ALSA: hda - Keep powering up ADCs on Cirrus codecs

2016-04-19T20:07:50+00:00

Although one weird behavior about the input path (inconsistent D0/D3
switch) on Cirrus CS420x codecs was fixed in the previous commit,
there is still an issue on some Mac machines: the capture stream
stalls when switching the ADCs on the fly.  More badly, this keeps
stuck until the next reboot.

The dynamic ADC switching is already a bit fragile and assuming
optimistically that the chip accepts the frequent power changes.  On
Cirrus codecs, this doesn't seem applicable.

As a quick workaround, we pin down the ADCs to keep up in D0 when
spec->dyn_adc_switch is set.  In this way, the ADCs are kept up only
for the system that were confirmed to be broken.

ALSA: hda/realtek - Add ALC3234 headset mode for Optiplex 9020m

2016-04-18T09:39:40+00:00

The Optiplex 9020m with Haswell-DT processor needs a quirk for the
headset jack at the front of the machine to be able to use microphones.

A quirk for this model was originally added in 3127899, but c77900e
removed it in favour of a more generic version.

Unfortunately, pin configurations can changed based on firmware/BIOS
versions, and the generic version doesn't have any effect on newer
versions of the machine/firmware anymore.

ALSA: hda - Don't trust the reported actual power state

2016-04-17T07:39:41+00:00

We've got a regression report that the recording on Mac with a cirrus
codec doesn't work any longer.  This turned out to be the missing
power up to D0 by power_save_node enablement.

After analyzing the traces, we found out that the culprit is that the
codec advertises the "actual" power state of a few nodes to be D0
while the "target" power state is D3.  This inconsistency is usually
OK, as it implies the power transition.  But in the case of cirrus
codec, this seems to be stuck to D3 while it's not actually D0.

This patch addresses the issue by checking the power state difference
more strictly.  It sends the power-state change verb unless both the
target and the actual power states show the given value.

We may introduce yet another flag indicating the possible broken
hardware power state, but it's anyway safer to set the proper power
state even in a transition (at least it's harmless as long as the
target state is same).  So this simpler change was applied now.

ALSA: hda - Fix inconsistent monitor_present state until repoll

2016-04-13T07:53:46+00:00

While the previous commit fixed the missing monitor_present flag
update, it may be still in an inconsistent state while the driver
repolls: the flag itself is updated, but the eld_valid flag and the
contents don't follow until the repoll finishes (and may be repeated
for a few times).

The basic problem is that pin_eld->monitor_present is updated in the
caller side.  This should have been updated only in update_eld().  So,
the proper fix is to avoid accessing pin_eld but only spec->temp_eld.

ALSA: hda - Fix regression of monitor_present flag in eld proc file

2016-04-13T07:52:26+00:00

The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI
monitor_present update] covered the missing update of monitor_present
flag, but this caused a regression for devices without the i915 eld
notifier.  Since the old code supposed that pin_eld->monitor_present
was updated by the caller side, the hdmi_present_sense_via_verbs()
doesn't update the temporary eld->monitor_present but only
pin_eld->monitor_present, which is now overridden in update_eld().

The fix is to update pin_eld->monitor_present as well before calling
update_eld().

Note that this may still leave monitor_present flag in an inconsistent
state when the driver repolls, but this is at least the old behavior.
More proper fix will follow in the later patch.
