can't get line in to come out thru speakers (Cinnimon 21.3)

[russbro]

I am attempting to put a guitar amp emulator thru my line in so I can hear it come out thru the speakers - when I plug the device in I am clearly getting line-in input from the built-in audio - I see the meter and input register when I strum the guitar.

But for the life of me I can't get the a mixer that takes both the PC audio and line-in and mixes them on the way out. (I use the Line Out built in audio on my motherboard as well) -

This is an older motherboard - I'll try and run some of the commands given here but I"m not seeing any errors - just what seems to be an internal mixer that isn't routing the line in to the line out for output - I do have an HDMI output but I keep that turned down and muted as I want what is in the speakers to come from the motherboard/monitors.

thanks for any assistance

side note I've also tried Alsamixer and I see a line setting which I craned - a headphone setting which I tried, and a line input but there's no meter on it -

I have a screenshot I can try to upload if need be - it apperas I have to load it to an image sharing site and can't just paste it in

[russbro]

pretty sure if I can figure out how to map this to output I'll be good

tried pactl load-module module-loopback but it's not mapping the line - some sort of buzz but not my line
