alsactl store/restore works for most parameters (e.g., clock rate, clock
source, SPDIF-flags etc), but not for the matrix mixer of the hdsp
cards. The reason is probably that the mixer element "numid=5" is a
complex mixer with three arguments, where the first two define the
address of the mixer element in the hardware mixer, and the third one
its value. Thus, all hardware mixer elements are accessed through a
single ALSA mixer element (the hdsp cards have up to 2*26^2=1352 mixer
elements). The read command of numid=5 always returns the triplet 0,0,0.
