Hack around the lack of a hardware prescaler on a number of WM codecs. Bass and treble controls should work on DAPs using these chips now, but will be prone to distort when boosting bass. Gut out UDA1380 code(!!) and switch to high bass cutoff and low treble cutoff in WM8975 driver.

Added zero crossing check before changing volume to avoid noise during volume changes. Removed extra volume sets. Added delay for vref to settle per app notes to reduce start up clicks.

FS#6096. Recording on PortalPlayer targets (H10, iPod Video, iPod 4g, iPod Color, iPod Nano).

2006-12-18T01:52:21+00:00

* Fix failed compile of enc_config.c when HAVE_MPEG2_SAMPR is not defined.
* Fix bug in AIFF encoder header creation on little endian targets.
* Add recording screen keymaps for H10 and iPod.
* Move pcm_playback PP specific code to target tree.
* Add recording code to wmcodec drivers.
* Add pcm_record code.

Some problems still remain:
* Playback doesn't work after recording until Rockbox is restarted.
* Gain control not implemented.
* Only 16-bit/44KHz for now. The hardware should be capable of up to 24-bit/96KHz.
* Line-in recording not tested on H10.
