hi all, new to these boards (and new to diy audio in general) so please be gentle 
and mods if i have put this thread in the wrong category, please feel free to move:
looking to use a single raspberry pi running pure data for multichannel audio with a high channel count, somewhere in the 30 channel range. i know of at least 2 8 channel cards and/or kits (suptronics x6000 and the audio injector octo), but i don't believe you can daisy chain these to a single rPi... or can you? in a paradigm where i need, say, 32 channels of audio, it seems silly to run 4 rPis but perhaps this is necessary. for this particular project, as long as there's no buzzing, the audio quality does not need to be hifi at all: i'm just running some sine tones to very cheap speaker cones. but i do want each speaker to have an independent channel.
apart from this probably sounding nuts to all but a niche group of you, is this possible to do? am i looking at the wrong products?
mea culpa if this is a dumb question or i'm in the wrong place - i'm very very new to this arena and looking forward to learning.

Regular inexpensive USB soundcards run at fullspeed (12Mbps). That is about enough for a single 7.1 (48kHz 16bit 8ch = 6.1Mbps, plus USB overhead).
For connecting multiple fullspeed 7.1 soundcards to 480Mbps USB2 port a hub with multiple transaction translators (MTT) is needed. I would assume that is a standard nowadays but please check first.
