Two HDA controllers are typically for the on-board codec and for the
GPU's HDMI outputs.

snd-hda-intel uses KBUILD_MODNAME for this string, so in theory, it
should not be possible for garbage to appear if the same string for
irq 48 is OK.

Which device is 0:1b.0 (see lspci)? And does the high number of
interrupts indicate that you did play sounds through it?
