I was using a somewhat old (~2 yrs now) version of the Audigy2 ZS Platinum Pro card w/external chassis. One thing I never got working was the 7.1 side channels. I was never able to see/turn on Side Ch sliders in AlsaMixer and could never find a playback port(s) to get sound out. These channels just didn't seem supported. Fast-forward to about a month ago and I built another machine and bought another identical Audigy2 ZS Platinum Pro sound card w/chassis and the AlsaMixer sliders for the side channels (driver support?) appeared immediately and I have verified that pcm_playbacks 15 & 16 are the L/R Side channels, respectively. As a test, I swapped the sound cards between two identical machines and the sliders followed the new card. Appearing where they never had before and disappearing from the machine originally hosting the new card. My questions are: 1) Was there an early version(s) of this card where the side channels aren't supported by the ALSA driver? 2) Could this be made to work? 3) If so, what info is needed and who needs it? Additionally, at some point in recent time, there is a minor new problem where upon initial boot (I think, but can't swear this is 100% reproducable) there is low level noise on all outputs. The fix is to unplug/replug the firewire-ish cable that connects the external chassis to the PCI card. This always eliminates the static. Could this be a problem with the card's initialization?
