      ALSA: hda: Use LPIB for Sony VPCS11V9E · e96d3127
      Daniel T Chen authored 
      BugLink: https://launchpad.net/bugs/586347



Symptom: On the Sony VPCS11V9E, using GStreamer-based applications with
PulseAudio in Ubuntu 10.04 LTS results in stuttering audio. It appears
to worsen with increased I/O.

Test case: use Rhythmbox under increased I/O pressure. This symptom is
reproducible in the current daily stable alsa-driver snapshots (at least
up until 21 May 2010; later snapshots fail to build from source due to
missing preprocessor directives when compiled against 2.6.32).

Resolution: add SSID for this machine to the position_fix quirk table,
explicitly specifying the LPIB method.

      ALSA: hda_intel: fix handling of non-completion stream interrupts · 9ef04066
      Clemens Ladisch authored 
      

Check that the interrupt raised for a stream is actually a buffer
completion interrupt before handling it as one.  Otherwise, memory
errors or FIFO xruns would be interpreted as a pointer update and could
break the stream timing.

      ALSA: hda: Use LPIB for Toshiba A100-259 · 4e0938db
      Daniel T Chen authored 
      BugLink: https://launchpad.net/bugs/549560



Symptom: on a significant number of hardware, booting from a live cd
results in capture working correctly, but once the distribution is
installed, booting from the install results in capture not working.

Test case: boot from Ubuntu 10.04 LTS live cd; capture works correctly.
Install to HD and reboot; capture does not work. Reproduced with 2.6.32
mainline build (vanilla kernel.org compile)

Resolution: add SSID for Toshiba A100-259 to the position_fix quirk
table, explicitly specifying the LPIB method.

I'll be sending additional patches for these SSIDs as bug reports are
confirmed.

This patch also trivially sorts the quirk table in ascending order by
subsystem vendor.

      ALSA: hda - Add position_fix quirk for Biostar mobo · 8815cd03
      Takashi Iwai authored 
      The Biostar mobo seems to give a wrong DMA position, resulting in
stuttering or skipping sounds on 2.6.34.  Since the commit
7b3a177b

, "ALSA: pcm_lib: fix "something
must be really wrong" condition", makes the position check more strictly,
the DMA position problem is revealed more clearly now.

The fix is to use only LPIB for obtaining the position, i.e. passing
position_fix=1.  This patch adds a static quirk to achieve it as default.

      ALSA: hda - HDMI sticky stream tag support · ef18bede
      Wu Fengguang authored 
      

When we run the following commands in turn (with
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0),

	speaker-test -Dhw:0,3 -c2 -twav  # HDMI
	speaker-test -Dhw:0,0 -c2 -twav  # Analog

The second command will produce sound in the analog lineout _as well as_
HDMI sink. The root cause is, device 0 "reuses" the same stream tag that
was used by device 3, and the "intelhdmi - sticky stream id" patch leaves
the HDMI codec in a functional state. So the HDMI codec happily accepts
the audio samples which reuse its stream tag.

The proposed solution is to remember the last device each azx_dev was
assigned to, and prefer to
1) reuse the azx_dev (and hence the stream tag) the HDMI codec last used
2) or assign a never-used azx_dev for HDMI

With this patch and the above two speaker-test commands,
HDMI codec will use stream tag 8 and Analog codec will use 5.

The stream tag used by HDMI codec won't be reused by others, as long
as we don't run out of the 4 playback azx_dev's. The legacy Analog
codec will continue to use stream tag 5 because its device id is 0
(this is a bit tricky).
