ALSA update 0.9.3a

  - PCM - recoded link group locking
  - MPU401 - replaced RX_LOOP and TX_LOOP bits with atomic_t variables
  - ICE17xx - moved ak4xxx routines to separate module (snd-ak4xxx-adda)
  - CS8427 - fixed initialization, added Q-subcode control
  - AC97 - added more patches for Wolfson codecs
  - CMIPCI - added 24-bit sample support for S/PDIF
  - maestro3 - fixes
  - via82xx - workaround for Award BIOS, dxs_support module parameter
  - ymfpci - fixed initialization
  - intel8x0 - code cleanups, recoded inialization of pcm streams
  - sa11xx-uda1341 - removed debug code and other cleanups
  - irqreturn_t cleanups

+    Module for AC'97 motherboards based on VIA 82C686A/686B, 8233,
+    8233A, 8233C, 8235 (south) bridge.
 
     mpu_port	- 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup
+		  [VIA686A/686B only]
     ac97_clock	- AC'97 codec clock base (default 48000Hz)
+    dxs_support	- support DXS channels,
+		  0 = auto (default), 1 = enable, 2 = disable,
+		  3 = 48k only
+		  [VIA8233/C,8235 only]
 
     Module supports autoprobe and multiple bus-master chips (max 8).
+
     Note: on some SMP motherboards like MSI 694D the interrupts might
           not be generated properly.  In such a case, please try to
           set the SMP (or MPS) version on BIOS to 1.1 instead of
           default value 1.4.  Then the interrupt number will be
           assigned under 15. You might also upgrade your BIOS.
     
+    Note: VIA8233/5 (not VIA8233A) can support DXS (direct sound)
+	  channels as the first PCM.  With this device, up to 4
+	  streams can be played at the same time.  If the playback on
+	  this PCM is noisy, try to specify dxs_channels option to 2
+	  or 3.
+
+    Note: for the MPU401 on VIA823x, use snd-mpu401 driver
+	  additonally.
