Booted without the option and played some FLACs with mpv via PulseAudio 
and no
error messages appear in dmesg. For the sake of completeness, my kernel 
params
are:

cryptdevice=UUID=xxx root=yyy rootflags=subvol=__active/rootvol
hugepagesz=1G default_hugepagesz=1G hugepages=12
isolcpus=4,5,10,11 nohz_full=4,5,10,11 rcu_nocbs=4,5,10,11
intel_iommu=on pci-stub.ids=10de:13c2,10de:0fbb,8086:8d20
nvidia-drm.modeset=1 quiet ro

% uname -a
Linux lomond 4.12.8-2-ARCH #1 SMP PREEMPT Fri Aug 18 14:08:02 UTC 2017 
x86_64 GNU/Linux

No VMs were running during the test.

Cheers,
