Hi R,
While skype can
use hardware inputs 1 or 2, if there is audio coming in on inputs 3
and 4, the audio for 3 and 4 is not sent through skype.
I think that's probably because the Linux version of Skype is hard-wired
to use the first two channels available. I don't use Skype personally,
but I suggest you check if it is trying to use the legacy /dev/dsp
interface of OSS (card 0 in ALSA).
You can probably switch your cards around so that the one you want to
use with Skype becomes /dev/dsp using something like the following
method (for 64 Studio or Debian):
As root, add lines like these to the end of your
/etc/modprobe.d/alsa-base file:
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-1 snd-rme9652
options snd-rme9652 index=1
alias snd-card-2 snd-usb-audio
options snd-usb-audio index=2
In this example, a Creative Labs Audigy is set to card 0 for Skype, an
RME Hammerfall is card 1 for jackd, and a USB midi connector is card 2.
Also, would I need a sound server like jackd to
achieve this
functionality?
I don't think JACK is the right solution for your scenario. You might
consider PulseAudio instead, which is more desktop 'consumer' orientated:

By the way, this probably isn't the best list to ask for help on
practical topics. In future, you could try:
