and fill it up with an example and generic method for module settings.
Close the bug when it's done. Thanks!

Title:
  snd-hda-intel needs machine-specific flags sometimes

Status in Puredyne Documentation:
  Confirmed

Bug description:
  On claude's laptop 'zebimus' booted with 2010-01-11T09:40 -dev.iso:

  lspci:
  00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
          Subsystem: Hewlett-Packard Company Device 306d
          Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
          Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
          Latency: 0, Cache Line Size: 64 bytes
          Interrupt: pin B routed to IRQ 22
          Region 0: Memory at db000000 (64-bit, non-prefetchable) [size=16K]
          Capabilities: <access denied>
          Kernel driver in use: HDA Intel
          Kernel modules: snd-hda-intel

  dmesg:
  [   40.597010] hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x000f0000

  mplayer with alsa output:
  audio is incredibly quiet even with everything turned up in alsamixer
  mplayer freezes at end of playback

  jackd:
  jackd watchdog: timeout - killing jackd (after about 6 seconds from launch)

  there are workarounds with kernel and module settings (boot-time
  flags, no recompilation necessary), but different machines may have
  different workarounds...
