00e076795f audio: split sample conversion and volume mixing 
Refactor the volume mixing, so it can be reused for capturing devices.
Additionally, it removes superfluous multiplications with the nominal
volume within the hardware voice code path.

38cc9b607f issue snd_pcm_start() when capturing audio 
snd_pcm_start() starts the capture process and ensures that the events
are delivered to the poll handler. Without the call, capture can be started
only when there is simultaneous playback running.

22d948a2d9 fix 100% CPU load when idle with ALSA 
Playback control function did not disable polling when playback stops.
Caused busy spinning of the main loop due to unprocessed events.

bdff253c8f audio: internal API change 
pcm_ops.run_out now takes number of live samples (which will be always
greater than zero) as a second argument, every driver was calling
audio_pcm_hw_get_live_out anyway with exception of fmod which used
audio_pcm_hw_get_live_out2 for no good reason.

866358211d alsa: add host suspend/resume support 
Both input and output streams may be in SND_PCM_STATE_SUSPENDED
after the host is suspended and resumed, meaning "Hardware is
suspended".  snd_pcm_readi() and snd_pcm_writei() will return
-ESTRPIPE if called while the stream is in this state.

Call snd_pcm_resume() to enable audio output and capture after
host resume.

2637872ba8 Ignore -Waddress for alsaaudio.c 
/usr/include/alsa/pcm.h contains:

#define snd_pcm_sw_params_alloca(ptr) do { assert(ptr); *ptr = (snd_pcm_sw_params_t *) alloca(snd_pcm_sw_params_sizeof()); memset(*ptr, 0, snd_pcm_sw_params_sizeof()); } while (0)

The assert generates: "error: the address of 'sw_params' will always
evaluate as 'true'" which combined with -Werror prevents alsaaudio.o
from being built with certain versions of GCC.
