I can confirm this in the way that I had very similar experiences.
Although I do not clearly remember the kernel version I was trying to
use, it was alsa 1.0.15 with a rme pcmcia digiface I.
No sound was audible, and hdspmixer did not show any signal on the
outputs, although (at least in the same configuration with 1.0.14) it
was sent to the device.

I just wanted to get some work done, so I did not delve into the problem
any deeper. But a fix would certainly be nice.
