and what stands for snd_hdsp anyway?

is it an ALSA device on its own, which correctly appears under 
/proc/asounds/cards as a PCI sound-card device? because the "snd" 
particle in RTIRQ_NAME_LIST stands only for ALSA PCI devices, USB and FW 
ones don't apply there--the correct procedure is about having "snd_hdsp" 
literally on RTIRQ_NAME_LIST, something you've already come around.

just in case, please `cat /proc/asound/cards` on reply.

hth.
cheers
