N900 Audio Stuff

N900 uses the TI tlv320aic34 codec, for which a datasheet can be downloaded from here: http://www.ti.com/product/tlv320aic34

ALSA

Routing Graph

This is an incomplete representation, but still useful for writing or understanding configuration files. I'm not sure about the order of the elements and whether the volume elements are analog or digital, because it's hard to figure those things out just by experimenting (I guess the information would be available in the datasheet, but I haven't checked that).

ADC HPF Cut-off

  Capabilities: enum
  Items: 'Disabled' '0.0045xFs' '0.0125xFs' '0.025xFs'
  Item0: 'Disabled'
  Item1: 'Disabled'

Cut-off frequency for the high-pass filters that are applied to the data coming from the ADCs. I guess Item0 is for the left ADC and Item1 is for the right ADC.

On Fremantle, the high-pass filter is enabled for the integrated microphone and disabled for headsets. I don't know why. Anyway, copying that setup shouldn't do much harm.

• microphone: enum = 0.0045xFs
• headset(in): enum = Disabled

AGC

  Playback channels: Front Left - Front Right
  Mono:
  Front Left: Playback [off]

Earpiece Function

  Capabilities: enum
  Items: 'Off' 'On'
  Item0: 'Off'

On Fremantle there's no "Earpiece Function", but there's "Earphone Function", which doesn't exist on Nemo. These probably refer to the same thing. There's also "Earphone" on Fremantle, which is apparently used for earpiece volume control. There's no obvious counterpart on Nemo, but "Mono DAC" seems to work pretty well as the earpiece volume control.

• tvout: enum = Off

HPCOM

  Capabilities: pswitch penum
  Playback channels: Front Left - Front Right
  Mono:
  Front Left: Playback [on]

On Fremantle this element doesn't exist, but unlike on Nemo, "HPCOM DAC" contains a switch. The switch on "HPCOM DAC" may have been moved to a separate element (this one).
