Bug#867548: Available for Additional Testing

[Mike Fuller]

Also for what it's worth, hw_parms output during playback on the same
device:

On Debian 9 / CentOS 7.5 / Ubuntu 16.04:
	access: MMAP_INTERLEAVED
	format: S16_LE
	subformat: STD
	channels: 2
	rate: 48000 (48000/1)
	period_size: 44096
	buffer_size: 88192

On Ubuntu 18.04:
	access: MMAP_INTERLEAVED
	format: S32_LE
	subformat: STD
	channels: 2
	rate: 48000 (48000/1)
	period_size: 1024
	buffer_size: 16384

I don't know why but...this is the only discernable difference I've been
able to find in all my testing. I've been unable to manually set format,
period_size, or buffer-size parameters in Debian's pulseaudio configuration
files (I am pretty sure its just user error).
