Is This Possible?

adamgolding

i'm almost certain this was possible with the creative drivers, but i haven't been able to find a way to do it with kx--here's what i want to do:

1. record from mic in (in stereo, or mono if that's all that's possible)
2. pass line in to spdif out (this part must be stereo)
3. but NOT pass mic in to spidf out

in the creative drivers you could use the windows mixer to select 'mic' under the recording control, and mute the mic in playback control (without muting the line in)...

i've been through the routing guides and dowloaded the ProFX update so i can separate the line in and mic in as mono, but i'm hoping what i describe above is possible...

if you have an audigy or audigy 2 card yes this is possible

adamgolding

ah, no i have an original sblive. (and with this card it *was* possible with CL drivers, which is why i was thinking i would find a way to do it with kx--how do the CL drivers achieve it, and why can't kX do this?)

thank you for your quick response!

dj_stick

ok now i see how you mean

try muting the microphone in the AC97 window, yet set it as the record source
then have the ac97 fader unmuted and levelled in the rec and i/o windows - see if that works

adamgolding

yeah, you'd think that would work, but it doesn't--as soon as i select something as the 'record source' all of the other controls do nothing--the selected source feeds into both record and playback, none of the other sources are audible, and the mute/unmute buttons do nothing.

only 'stereomix' or 'monomix' make those sliders do anything, and in this case, you can't control what you hear and what you record separately...

You want to do something similar, except that you want to pass line in to spdif out. Maybe this will help you.

adamgolding

many thanks for your response--however that is exactly what i have tried many times, and it has never worked:

1. in my case, i turned off the swap, and unchecked digital output only. i have no analog speakers connected so i watched the peak in the standard dsp setup to see what was going to front analog

2. did an AC97 reset just to be sure

3. line in is selected as recording source by default, and its slider is MUTED, yet i can hear it through digital, and see it on peak

4. unmute line in, *nothing changes*

5. select mic as recording source--now i can't hear line or see it on peak, but i hear and see the mic instead

6. set ac97 record level to 0. still hear mic insted of line.

(the ac97 level in 'ins n outs' was at 0 all this time--if i mute it, i never hear anything from ac97, line OR mic)

also, when i leave the recording page and come back, the ac97 record level has jumped to -1--this happens every time i set it to 0...

now, digital out and analog front get their data from the same place in the router, so if the quoted method works for analog, it should work for digital. this makes me thing that something buggy is going on, or it is dependent on the model of the card--mine is an original sblive.

Tril

I read the help from the drivers and the method I suggested will only work for analog mode. I don't know if what you are trying to do is possible.

adamgolding

Tril--thanks for your further help--can you tell me where you found that in the help file?

also--what would cause this to only work in analog? i can't see what would do it in the DSP window--is there something behind the scenes going on?

Tril

It's in Appendix A, kX Signal Flow Diagram.

The diagram at the top shows it too. The volume sliders in the AC97 section of the mixer are probably the 'Vol' you see in white squares. The diagram shows that the output from there goes directly to the front speakers.

adamgolding

aha--well that *almost* makes sense--except where is the digital out on this diagram? the 'front output' is the same box in the digital output only diagram--makes it look like the box refers to either/both outputs????
