ALSA: hda - Fix GPIO for Acer Aspire 3830TG

2013-10-13T23:08:34+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.

ASoC: ab8500-codec: info leak in anc_status_control_put()

commit d63733aed90b432e5cc489ddfa28e342f91b4652 upstream.

If the user passes an invalid value it leads to an info leak when we
print the error message or it could oops.  This is called with user
supplied data from snd_ctl_elem_write().

ALSA: hda - Add Toshiba Satellite C870 to MSI blacklist

2013-09-27T00:18:14+00:00

commit 83f72151352791836a1b9c1542614cc9bf71ac61 upstream.

Toshiba Satellite C870 shows interrupt problems occasionally when
certain mixer controls like "Mic Switch" is toggled.  This seems
worked around by not using MSI.

ALSA: hda - hdmi: Fallback to ALSA allocation when selecting CA

2013-09-27T00:18:14+00:00

commit 18e391862cceaf43ddb8eb5cca05e1a83abdebaa upstream.

hdmi_channel_allocation() tries to find a HDMI channel allocation that
matches the number channels in the playback stream and contains only
speakers that the HDMI sink has reported as available via EDID. If no
such allocation is found, 0 (stereo audio) is used.

Using CA 0 causes the audio causes the sink to discard everything except
the first two channels (front left and front right).

However, the sink may be capable of receiving more channels than it has
speakers (and then perform downmix or discard the extra channels), in
which case it is preferable to use a CA that contains extra channels
than to use CA 0 which discards all the non-stereo channels.

Additionally, it seems that HBR (HD) passthrough output does not work on
Intel HDMI codecs when CA is set to 0 (possibly the codec zeroes
channels not present in CA). This happens with all receivers that report
a 5.1 speaker mask since a HBR stream is carried on 8 channels to the
codec.

Add a fallback in the CA selection so that the CA channel count at least
matches the stream channel count, even if the stream contains channels
not present in the sink speaker descriptor.

Thanks to GrimGriefer at OpenELEC forums for discovering that changing
the sink speaker mask allowed HBR output.

ALSA: hda - Re-setup HDMI pin and audio infoframe on stream switches

2013-09-27T00:18:14+00:00

commit b054087dbacee30a9dddaef2c9a96312146be04e upstream.

When the transcoder:port mapping on Haswell HDMI/DP audio is changed
during the stream playback, the sound gets lost.  Typically this
problem is seen when the user switches the graphics mode from eDP+DP
to DP-only configuration, where CRTC 1 is used for DP in the former
while CRTC 0 is used for the latter.

The graphics controller notifies the change via the normal ELD update
procedure, so we get the intrinsic event.  For enabling the sound
again, the HDMI audio driver needs to reset the pin and set up the
audio infoframe again.

This patch achieves it by:
- keep the current status of channels and info frame setup in per_pin
  struct,
- check the reconnection in the intrinsic event handler,
- reset the pin and the re-invoke hdmi_setup_audio_infoframe()
  accordingly.

The hdmi_setup_audio_infoframe() function has been changed, too, so
that it can be invoked without passing the substream instance.

The patch is mostly based on the work by Mengdong Lin.

ASoC: mc13783: add spi errata fix

2013-09-27T00:18:13+00:00

commit 9f6f0afbb9fdabf6dcac642dfec457f28981e3f8 upstream.

The MC13783 Chip Errata, Rev. 4 says, that depending on SPI clock
and main audio clock speed, the Audio Codec or Stereo DAC do sometimes
not start when programmed to do so. This is due to an internal clock
timing issue related to the loading of the SPI bits into the audio block.

On an i.MX27 based system, this issue lead to switched audio channels under
certain circumstances: RTC + Touch + Audio are used and loaded at startup.

The mentioned workaround of writing registers 40 and 41 two times is implemented
here.
