e69d567d9e Bring consistency to pcm implementation and samplerate handling. Less low-level duplication. A small test_sampr fix so it works on coldfire again.

0d49141637 Since several S/PDIF sources do not set the valnogood bit properly, valnogood shouldn't be considered as an error.

af395f4db6 Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled).

8a6291dd63 More iAudio M3 work. Target build compiles, but same problem regarding plugins as the simulator. Boots to the menu, but it can't be used yet because only main & remote Play button work. USB works.

6077e5b7c8 Unify PCM interface just above the hardware driver level for all targets including the sims. Perform lockout of audio callback when changing states. Weird new playback or recording trouble? Check before and after this revision first though things seem quite sound.

2d48d0ffa6 Straighten out some audio path APIs and misc. audio stuff. Having recording is not a prerequisite to having input/output source selection which is probably most useful when adding a audio input features like FM to a new port without forcing recording to be implemented first.

8f659ae8d3 Use bitmasks to define which inputs are available. Makes it easier to remove old assumptions of which are available. Inspired by e200 being unique in having FM Radio and Mic but no Line. Doesn't remove the assumption that Mic is available or that one of Mic and/or Line is available just to avoid excessive #ifdef'ing until needed.

6c8772d6db x5/M5: Finally get rid of filter selection aberrations when switching to 88.2kHz sampling rate which affected both the DAC and ADC. Turning off the DAC and ADC before changing the internal codec frequency seems to cure the remaining glitch of the filters not being correctly selected by the TLV320. Some FIFO reset changes that help keep it stable as well. Supporting 88.2KHz on iAudio has been a tricky ordeal. Also made sure to ok the HW tone controls on iRiver. :)

abf41e3481 H100 Series: Fix FS#6810 - Distortion on Bass/Treble usage. Coldfire PCM needed a refinement in the init sequence for the UDA1380 after audio init changes. Apparently it doesn't like its registers altered before the Coldfire I2S is properly initialized.

c2d2106fd7 Audio Init: Just can't stand that heirarchy. Add one level of abstraction. Might come in handy anyhow. Use sound.h instead of the conditional includes for audio hardware headers. If someone doesn't like that, yell at my evil twin. :)

5d63776a24 Reenable aynchronous audio init stage. Really just single stage with aynchronous enabling of outputs. Keeps audio_init last so prior init steps can use the audiobuffer in any desired way. Audio will be fully initialized by the time the UI is entered. Playback of voice or audio will be delayed properly until audio hardware is ready.

633f388002 Coldfire targets: Shuffle IRQ levels around to have all interaction between low level audio function calls and DMA be atomic. Make recording and playback independently startable and stoppable so one can be running and not interfere with the other. All tests I can do at the moment check out ok (play, record, play+record, FM radio on iRivers, S/PDIF on H120 (w/running optical on/off), and on-the-fly samplerate changes). Recording tested for well over an hour run and no problems.

8867d00141 More catching up on old work. Refine audio interface setup on Coldfire. Stop the funky glitching on the iAudio stuff when starting recording esp. at 88.2kHz. (probably due to the bidi interface). iRivers don't seem to care what you do. TLV320 still seems to have a little trouble selecting it's filters correctly for 88.2kHz or it could be some odd phasing effect. Get rid of the horrible reset parameter in pcm_apply_settings as it can decide for itself.

51189b4cb4 Small change to PCM recording API for low latency effects. Latency can be as low as 14 samples from input to output including the FIFOs (ColdFire) but 16 is more reasonable an expectation if only tranferring one sample per interrupt (\!). May convert PCM playback to use the same method as it can still be used in the old manner with some slight mods but has the potential to enable new features since it is more flexible.

7d00f97460 PCM: A few tiny changes. 1) Recording a) Flush all pending files if filename queue is full or else perpetual flushing of 1 will occur at low bitrates and short split times. b) #ifdef out currently unused bits and save little less than 1/2K 2) Cleanup some declarations.
