ALSA: hda - Fix inverted internal mic not indicated on some machines

2013-11-04T12:35:20+00:00

commit ccb041571b73888785ef7828a276e380125891a4 upstream.

The create_bind_cap_vol_ctl does not create any control indicating
that an inverted dmic is present. Therefore, create multiple
capture volumes in this scenario, so we always have some indication
that the internal mic is inverted.

This happens on the Lenovo Ideapad U310 as well as the Lenovo Yoga 13
(both are based on the CX20590 codec), but the fix is generic and
could be needed for other codecs/machines too.

Thanks to Szymon Acedański for the pointer and a draft patch.

ALSA: us122l: Fix pcm_usb_stream mmapping regression

2013-11-04T12:35:20+00:00

commit ac536a848a1643e4b87e8fbd376a63091afc2ccc upstream.

The pcm_usb_stream plugin requires the mremap explicitly for the read
buffer, as it expands itself once after reading the required size.
But the commit [314e51b9: mm: kill vma flag VM_RESERVED and
mm->reserved_vm counter] converted blindly to a combination of
VM_DONTEXPAND | VM_DONTDUMP like other normal drivers, and this
resulted in the failure of mremap().

For fixing this regression, we need to remove VM_DONTEXPAND for the
read-buffer mmap.

ALSA: hda - Fix mono speakers and headset mic on Dell Vostro 5470

2013-10-18T17:54:58+00:00

This is a backport for stable. The original commit SHA is
338cae565c53755de9f87d6a801517940d2d56f7.

On this machine, DAC on node 0x03 seems to give mono output.

Also, it needs additional patches for headset mic support.
It supports CTIA style headsets only.

ALSA: hda - Fix microphone for Sony VAIO Pro 13 (Haswell model)

2013-10-18T17:54:54+00:00

commit 88cfcf86aa3ada84d97195bcad74f4dadb4ae23b upstream.

The external mic showed up with a precense detect of "always present",
essentially disabling the internal mic. Therefore turn off presence
detection for this pin.

Note: The external mic seems not yet working, but an internal mic is
certainly better than no mic at all.

ASUS N56VZ needs a fixup for the bass speaker pin, which was already
provided via model=asus-mode4.

ALSA: hda - hdmi: Fix channel map switch not taking effect

2013-10-18T17:54:53+00:00

commit 39edac70e9aedf451fccaa851b273ace9fcca0bd upstream.

Currently hdmi_setup_audio_infoframe() reprograms the HDA channel
mapping only when the infoframe is not up-to-date or the non-PCM flag
has changed.

However, when just the channel map has been changed, the infoframe may
still be up-to-date and non-PCM flag may not have changed, so the new
channel map is not actually programmed into the HDA codec.

Notably, this failing case is also always triggered when the device is
already in a prepared state and a new channel map is configured while
changing only the channel positions (for example, plain
"speaker-test -c2 -m FR,FL").

Fix that by always programming the channel map in
hdmi_setup_audio_infoframe(). Tested on Intel HDMI.

ALSA: snd-usb-usx2y: remove bogus frame checks

2013-10-18T17:54:53+00:00

commit a9d14bc0b188a822e42787d01e56c06fe9750162 upstream.

The frame check in i_usX2Y_urb_complete() and
i_usX2Y_usbpcm_urb_complete() is bogus and produces false positives as
described in this LAU thread:

  http://linuxaudio.org/mailarchive/lau/2013/5/20/200177

This patch removes the check code entirely.

ALSA: hda - Fix GPIO for Acer Aspire 3830TG

2013-10-14T01:14:31+00:00

commit 4a4370442c996be0fd08234a167c8a127c2488bb upstream.

Acer Aspire 3830TG seems requiring GPIO bit 0 as the primary mute
control.  When a machine is booted after Windows 8, the GPIO pin is
turned off and it results in the silent output.

This patch adds the manual fixup of GPIO bit 0 for this model.
