Michael Walle 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.

Juergen Lock 72ff25e4e9 Workaround for broken OSS_GETVERSION on FreeBSD, part two 
Turns out on those versions of FreeBSD (>= 7.x) that know OSS_GETVERSION
the ioctl doesn't actually work yet (except in the Linuxolator), so if
building on FreeBSD assume the sound drivers are new enough if the ioctl
returns the errno it does currently on FreeBSD.

(Rev 2 after private discussion with malc.)

malc 3d709fe73a oss: fix fragment setting 
Previous patch introduced subtle regression, in cases when
OSS_GETVERSION fails the code wasn't falling back to
SNDCTL_DSP_SETFRAGMENT.

malc 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.

At least on one system zero is returned in either fragsize or
fragstotal (reported by Dave Scott), this results in an audio_calloc
failing the audio_bug check and another ominous error message. Fail
early and blame the system.
