Okay, well starting from the very beginning... - I want 5.1 channel output from my sound card. All the time. - This means that when I play stereo sound I want it routed to the front two speakers as well as the rear two speakers. I also want the low frequencies from both input channels routed to the subwoofer channel. - When I play mono sound, I want it routed to in the same way as stereo - front and rear speakers, and subwoofer. - When I play 5.1 sound, I want it routed to each correct channel (i.e. I don't want the front speakers duplicated out the back, which the 'duplicate front' mixer control does.) This is relatively simple, but the difficulty arises because I also want every single channel routed via a single LADSPA plugin before it gets to the speakers. This is an equaliser plugin, which boosts specific frequencies that my external amplifier seems to lack. I used to have this working with stereo, but I was having some trouble getting the routing correct with my old ALSA version (1.0rc2 or something.) I upgraded to 1.0.11rc1, however the routing then went haywire - which I then discovered was because the LADSPA plugin converted everything to mono (or rather stereo with the same signal in both channels.) My intent was to get LADSPA going again with stereo, which would allow me to resume my quest to get 5.1 sound working too. Hopefully this gives you some idea where I'm coming from!
