Subject: [ALSA] ice1712 - Fix wrong register value for DMX 6FIRE

I have just discovered I made an error in the register value set in 'Limit
dmx6fire to 6 dacs' patch (bug1472).  The value set should be '2a' not '0a'
as in the original patch, which unintentionally disables the 2nd MPU 401
UART.

+      opl3_port		- OPL3 port # (default: 0x388)
+
+    This module supports multiple cards.
+    The driver requires the firmware loader support on kernel.
+    You need to install the firmware file "riptide.hex" to the standard
+    firmware path (e.g. /lib/firmware).

Subject: [ALSA] Clean up PCM codes (take 2)

- Clean up initialization and destruction of substream instance
  Now snd_pcm_open_substream() alone does most initialization jobs.
  Add pcm_release callback for cleaning up at snd_pcm_release_substream()
- Tidy up PCM oss code

From 060d77b9c04acd7aef60790398a53f731db8c8fe Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Mon, 27 Mar 2006 16:44:52 +0200
Subject: [ALSA] Fix / clean up PCM-OSS setup hooks

- Fix possible race of referring the setup hook from the running PCM
- Fix memory leak in an error path of proc write
- Clean up the setup hook parser

Subject: [ALSA] AdLib FM card driver

Attached you'll find an ALSA driver for AdLib FM cards. An AdLib card is
just an OPL2, which was already supported by sound/drivers/opl3, so only
very minimal bus-glue is needed. The patch applies cleanly to both
2.6.16 and 2.6.16-mm1.

The driver has been tested with an actual ancient 8-bit ISA AdLib card
and works fine. It also works fine for an OPL3 {,emulation} as still
found on many ISA soundcards but given that AdLib cards don't have their
own mixer, upping the volume from 0 might be a problem without the card
driver already loaded and driving the OPL3.

Subject: [ALSA] HDA/Realtek: multiple input mux definitions and pin mode
 additions

The following patch relative to CVS from 20060324 adds the following
features to the Realtek HDA codec.

1) Define two new pin modes: ALC_PIN_DIR_IN_NOMICBIAS and
   ALC_PIN_DIR_INOUT_NOMICBIAS.  These can be used with jack mode switch
   definitions in mixers to prevent the user being offered the mic bias
   options if the hardware doesn't support it.

2) Add the ability to have different input mux definitions for different
   ADCs.  This is needed because the ALC260 chip uses different mux layouts
   for the two onboard ADCs.  A new field (num_mux_defs) was added to the
   alc_spec and alc_config_preset structures to support this.

3) Adjust numerous comments to make them consistent with the above changes.

4) Utilise the new multi-mux definition functionality for the ALC260 fujitsu
   model to allow recording of the mixer output.

5) Utilise the new multi-mux definition functionality for the ALC260 test
   model to make the mux selections a little less confusing.

6) Allow the headphone jack of the ALC260 acer model to be retasked in
   the mixer.

6) Utilise the new multi-mux definition functionality for the ALC260 acer
   model to give access to the mixer output and the retasked headphone
   jack.

At this stage the *_NOMICBIAS modes are not used.  We have reports that the
"Line" jack of at least some Acer models doesn't pass the bias out, and we
also know that NIDs 0x0f and 0x10 don't seem to accept the mic bias requests
at all.  However, I feel we need to collect more evidence on both counts
before committing to the use of *_NOMICBIAS.  In the case of the Acers, it's
not clear whether this issue (probably caused by the inclusion of DC
blocking capacitors) affects all Acer models or just a small number.  With
the issue with NIDs 0x0f and 0x10 it's unclear whether this is a hardware
bug which will be addressed in later chip revisions or if it's an
intentional restriction.  The datasheet makes no mention of the restriction
so at this stage I'm inclined to consider it a hardware bug.  Comments in
the source reflect this reasoning.

On a similar theme, the headphone jack of the Fujitsu S7020 also doesn't
appear to pass mic bias voltage.  I'm still investigating this however.

With the ability to retask the headphone jack, owners of ALC260-based Acer
laptops should now be able to record 4 channels of audio if they desire. The
multiple mux definitions allow this jack to be presented from both ADCs
(since this mux input is one of those which differs between the muxes).

This patch has been tested on a Fujitsu S7020 laptop and appears to behave
itself both for the "test" and "fujitsu" models.  Definitions using only a
single mux specification also work.  Other ALC chips should be fine but I
cannot test these myself.  The "auto" modes should also continue to function
but again I have not verified this.

From 0b2dcd5d6a9a3e27fdd67053e526388f9f2ea33b Mon Sep 17 00:00:00 2001
From: Andreas Mohr <andi@lisas.de>
Date: Tue, 28 Mar 2006 12:56:14 +0200
Subject: [ALSA] maestro3.c: fix BUG, optimization

- fix brown-paper-bag locking bug (lock() / return / unlock())
- improve central function snd_m3_update_ptr()
  (avoid expensive integer divisions)
- add cpu_relax() to busy-wait I/O loop as recommended
  (does this require special macro support in ALSA for older kernels??)
- constify several structs
- spelling updates

Subject: [ALSA] Test volume resolution of usb audio at initialization

Test the volume of usb audio whether actually it works and adjusts
the resolution value according to it.

Some USB audio devices report a lower resolution than it reacts.
The only possible check is to write and read a volume value.

Subject: [ALSA] pcxhr - Fix the crash with REV01 board

On a new board revision for pcxhr boards, the
PCXHR_CHIPSC_GPI_USERI bit is no more supported.
The cards concerned have a REV01 in their PCI ID.

As the current driver tests this bit and does not load the
first Xilinx binary when it's 1, the card will crash on Xilinx
access over PCI. (the PCI will freeze ....)

The fix (fix to version 1.0.11rc4) works for both REV00 and
REV01 cards.

Subject: [ALSA] Add Aux input switch control for Aureon Universe

This patch adds a mixer control which allows the user to switch the Aux
playback between the internal Aux jack, Wavetable, and Rear Line-In on
Aureon Universe cards.

For switching, a PCA9554 (8-line GPIO with I2C interface) and a 74HC4052
(dual 4-way mux/demux) are used.  Output 0 and 1 of the PCA9554 are
connected to the select pins of the 74HC4052. The I2C interface of the
PCA9554 is connected to the card's internal SPI bus which is also used
to control the WM8770 and CS8415. SPI and I2C on the same lines...

To communicate with the PCA9554 the WM8770 and CS8415 are disabled and
an I2C Stop Condition is generated before the Start Condition (needed
for synchronisation because other SPI traffic appear to confuse the
PCA9554). Then a normal I2C data transfer takes place.  Programming must
be done ridiculously slow; in theory, 4.7us is the minimum delay time
for normal-speed I2C according to the datasheet, but even with 10us
switching was unreliable.  The Windows driver from Terratec does the
programming very slowly, too (checked with an oscilloscope).
