      ALSA: hda - iMac 9,1 sound patch. · 4b7e1803
      由 Justin P. Mattock 提交于 
      This is an updated patch for the Apple iMac 9,1 model to add sound.
Original patch posted here:
http://article.gmane.org/gmane.linux.alsa.devel/61361/match=

I have been using this patch for a while now
and have to say it works vary well, except for a few minor 
things:

	With the iMac 24-inch 3.06GHz Intel Core 2 Duo
	everything seems to be working as it should,
        although I have not looked into the microphone
	(never really use one, nor have any apps to test,
	my guess is it doesn't work, or I never figured out how
	to get it to work).

	With the iMac 24-inch 2.66GHz Intel Core 2 Duo
	everything is the same as with the above machine 
	except I'm hearing a light scratchy/distortion noise
	come out of the speakers when using headphones(above machine
	does not do this).

Other than that the sound level is great(especially with good Dj headphones).

      ALSA: snd-pcsp: add nopcm mode · bcc2c6b7
      由 Stas Sergeev 提交于 
      Currently, if the high-res timers are unavailable, snd-pcsp does not
initialize. People who choose it over pcspkr, loose their console beeps
in that case and get annoyed.
With this patch, the console beeps remain regardless of the high-res
timers. Additionally, the "nopcm" modparam is added to forcibly
disable the PCM capabilities of the driver.

      ALSA: dummy - Fake buffer allocations · a68c4d11
      由 Takashi Iwai 提交于 
      Instead of allocating the real buffers, use a fake buffer and ignore
read/write in the dummy driver so that we can save the resources.
For mmap, a single page (unique to the direction, though) is reused
to all buffers.

When the app requires to read/write the real buffers, pass fake_buffer=0
module option at loading time.  This will get back to the old behavior.

      ALSA: Add debug module option · 36ce99c1
      由 Takashi Iwai 提交于 
      Add debug module option to snd core.
This controls the debug print level.  When CONFIG_SND_DEBUG_VERBOSE
is set, you can suppress the debug messages by giving or changing this
parameter to a lower value.  debug=0 means no debug messsages.
As default, it's set to the verbose level 2.

Since this option can be changed dynamically via sysfs file, you can
suppress the verbose debug messages on the fly, which wasn't possible
before.

      ALSA: hda - Acer Aspire 8930G support · 3b315d70
      由 Hector Martin 提交于 
      Short story: this laptop has 5.1 built-in speakers which you *really*
want to use (the not-so-"sub" woofer is what makes the audio above
average for a laptop), so 6-channel support is important (plus a decent
asound.conf to upmix stereo). It also has the 3 typical jacks that ought
to have a selectable mode. And it's based on ALC889, which sucks.

Rationale/explanations:

The const_channel_count stuff was added because, for a laptop like this,
you always have 6 channels available (internal speakers) but still need
to set the mode for the 3 external jacks. Therefore, the device always
needs to be in 6-channel mode but there still needs to be a mixer
control for the jack mode. You could use line/mic-in at the same time as
the 6 internal speakers, for example. You might be tempted to make it
even smarter by dynamically switching the max channel count when
headphones are plugged in (therefore muting the internal speakers and
reducing the physical channel count to the jack channel mode), but as a
user I consider this to be harmful because I want the audio to blow up
to 6 channels / upmixed as soon as I unplug the headphones, and having
opened the device while in 2-channel mode would prevent this from
working (and always making 6-channel mode available doesn't do any harm).

The hardware needs EAPD turned on and the DACs routed to the internal
speaker pins, so the patch adds those verbs.

The ALC889 CLFE and subsequent (side/aux, here unused) DACs do NOT work
by default, at least here. I wasted much time trying to talk to
Realtek/pshou about this, but they just kept sending me useless updates
to patch_realtek.c that did nothing relevant. In the end I gave up and
brute forced the issue by trying to flip every bit in the proprietary
coefficient registers, and eventually found the two magic registers that
need to be cleared to enable all DACs. I have only heard Acer users
complain, but that might be because ALC889 is pretty new and using 5.1
(and noticing the missing center/lfe channels) might not be that common.
If this is a generalized issue with all ALC889 systems then those verbs
should probably be moved to a common verb array.

The internal mic is untested and probably doesn't work.

These settings will probably work for other Acer Gemstone laptops with
the same 5.1 speaker config. When identified, those should be added to
the PCI subsystem ID list.

      ALSA: Enable PCM hw_ptr_jiffies check only in xrun_debug mode · c87d9732
      由 Takashi Iwai 提交于 
      The PCM hw_ptr jiffies check results sometimes in problems when a
hardware doesn't give smooth hw_ptr updates.  So far, au88x0 and some
other drivers appear not working due to this strict check.
However, this check is a nice debug tool, and the capability should be
still kept.

Hence, we disable this check now as default unless the user enables it
by setting the xrun_debug mode to the specific stream via a proc file.
