This Haswell related bug sounds very similar and possibly relevant to my
Haswell machine:

I have not tried your patch, but found that intel_iommu=on,igfx_off
snd_hda_intel.align_buffer_size=1 fixes the problem. Should I still
try the patch?..."

Haswell HDMI audio users are affected by a longstanding kernel IOMMU bug:
https://bugzilla.kernel.org/show_bug.cgi?id=60769 . To make sure that your
report is not a duplicate, please add the following kernel command line
option and reboot: intel_iommu=on,igfx_off If that alone doesn't help,
please try: intel_iommu=on,igfx_off snd_hda_intel.align_buffer_size=1
