ALSA: Further rework:
* Get rid of non-async (ie tick task) mode due to inherent brokenness * Get rid of nonblock mode; we never write if buffers aren't sufficient * Move driver init into pcm_open() instead of pcm_init() * Much better underrun handling * Better error handling in some situations * Add in recording functionality * Use smaller audio buffers to avoid glitching * Don't start audio buffer with silence * Allow device name to be overridden by target Recording portions based on work done by Lorenzo Miori in g#633 Change-Id: I0197bdc1749c28109eb79def1e6a3e1d62d8cef3
