bf65676226 Removed muting from pcm buffer during starts, stops and pauses for tlv320 and uda1380. Far less in the way of pops now. Voice during FM radio playback keeps radio steady. If it is determined that other audio codecs don't benefit from this remove the muting code and defines altogether. Saving the state and not resetting more than needed seems to prevent popping more effectively than muting at DMA starts and stops. Voice can click a little if truncating a clip (not annoyingly though) but that should be handled by a DSP fade out over a few ms instead-- a side benefit would be a general DSP fade rather than using volume control.

5dd0775924 Calculation was wrong in pcmbuf_is_same_size such that is would almost certainly return false.

0f5cb94aa4 Big Patch adds primarily: Samplerate and format selection to recording for SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs.

a85044bf9e New scheduler, with priorities for swcodec platforms. Frequent task 
switching should be more efficient and tasks are stored in linked
lists to eliminate unnecessary task switching to improve performance.
Audio should no longer skip on swcodec targets caused by too CPU
hungry UI thread or background threads.

413da2a3d9 Rework PCM buffer 
* Linked list instead of static array buffer pointers
* Variable sized chunks
* Improved mix handling
* Reduction in duplicated code
* Reduced IRAM usage w/o sacrificing performance
* Converted to almost entirely unsigned math
* Add pause function to reduce pcm_* exposure to playback.

This WILL break playback on the iPod until linuxstb makes a followup commit.
