Howdy folks,
I've got an idea for a game I'd like to build for my kids. To make it work
like I want I need to have four mono sound channels feeding into four
physical speakers. To make that work it looks like my options are:
1) Use four separate sound cards (PCI or USB)
2) Do some coding to use each channel in a sound card to drive a
separate speaker.
I like option two the best because its cost effective, and I think the newer
Sound Blaster cards will drive four speakers (even if not, two cards is
better then four). Unfortunately I don't
think Linux's OSS can handle either of these options so now I'm looking to
Alsa as a solution. From reading the Alsa manual it looks like I can do what
I want by interleaving the sound buffers in one memory space. Is that the
best approach? Its been a week since I read the manual, so I don't recall if
I can do something like a select() loop to feed data to the sound cards as
needed, but I'm thinking that would be easier if the method is available.
Can anyone give me some guidance on how to proceed? I would appreciate it.
Also, I haven't bought any sound cards yet, so if there is another make that
might be better suited for this application (and is also cheap) please clue
me in.
Thanks,
Christopher
