Hi list,

I have recently set up my RME Multiface I + Cardbus card on a dualboot
Windows XP / Debian laptop (Samsung Q45).

Under Windows, everything is working fine, but under Debian, I am
experiencing some strange behavior of hdspmixer (version 1.6), i.e. the
routing does not seem to correlate to the actual fader positions, and
all faders seem to be dead, i.e. moving them does not seem to affect the
routing in any way.

I am aware that a similar problem has been described by Tim Blechmann et
al. in 2004. However, I am not experiencing any of the distorted
playback they have reported then; all signals seem to be clean.

Here is some info on the CardBus from lspci:
04:09.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev b4)
(I remember reading about trouble with Ricoh / Multiface combinations
but can't remember any details.)

By the way, the hdspmixer's VU meters reflect the messed up routing,
i.e. where there is some output on the VU meter, there is also a signal.

Has anyone experienced similar problems? I would appreciate any hints.
