Unhappy hdmi audio only working once (per boot) after upgrading from 256.53 to 260.19.29


just today i finally upgraded my nvidia drivers from 256.53 to 260.19.29. before the upgrade, hdmi audio was working just fine, including ac3 pass-through.
now, though, audio over hdmi is only working the very first time i start x, after that i have to reboot to regain sound. this is a very weird issue, and after browsing through several threads, changing module options (enable_msi and probe_mask), asound.conf and trying most of the other suggestions, i resorted to recompiling the 256-series module for the new kernel.
this might be a workaround for now, but i ultimately want to be able to upgrade to newer nvidia drivers

here's my aplay -l and -L output:

speaker-test works the first time after x is started, on subsequent tries it appears to be playing, although no sound is audible, also the usual "click" (my receiver switching inputs) can't be heard, so i'm sure it's not just muted.

i'm on an asus m3n78-em, with a mcp78 chipset and a geforce 8300 igp, running archlinux, kernel 2.6.36.
any help or suggestions would be greatly appreciated!
