Hi,

I'm trying to get my electric guitar connected to
my sound card.
Keeping the card's input gain low keeps away the noise, but
produces a very low signal. I can put Jamin right after that and crank
up the input gain, but there's a maximum to it and I'm not sure whether
that's the right approach.
Jamin is not the right tool for playing live through it. It has a builtin
delay of >10ms which adds to jackd's latency. Use jack-rack for the effects
you want.
Turning up the card's input volume increases the
gain, of course, but it
delivers a lot of very ugly noise as well. If I connect a microphone to
the port, I get a high-gain signal without noise.
The card's an SB Live! Platinum, and the mic port seems to be the only
capture port usable by Jack. The cabling for the guitar is all new.
1) There is an electrical difference between mic- and line-inputs/-signals. It
is _no_ wonder it sounds strange and distorted. You have to use a line-input
or even better an instrument input. And the SBLive has line-ins as well and
they are usable with jack. And with a LiveDrive you get even more...
2) The mic-input on the SBLive might be better than a mic-input on
onboard-cards but it is still crap.
3) Guitars do output a lot of noise. That is way the combo-speakers have a
limited frequency-range. :-)
The best bet is to use some external (guitar-)effect that has instrument-in
and line-out and connect that line-out to the line-in of the soundcard.
And if you use hw:0,3 for playback and hw:0,2 for record in jack you get 16
ins and outs and you only have to find the right ones (with meterbridge for
example).
Hope that helps,
Arnold
