Here’s what I did, in order:

1. I installed a clean image of the zynthian gongorna
2. Run apt-get update, upgrade; Upadte-dist; Rpi-update and reboot
3. Update Zynthian
4. Since I’m using an HDMI screen, I followed the steps in [this post](https://discourse.zynthian.org/t/zynthian-with-a-7-display/523)
5. On file /zynthian/zynthian-ui/zynthian.sh changed:

function alsa\_in\_start() {  
Start alsa\_in audio input  
while [1]; do  
/usr/bin/\_alsa\_in -d **hw:0**  
sleep 1  
done  
6) Alsamixer Configuration:

And it worked perfectly!

Here a little set:

For guitar the line input of the audioinjector is not very good, so I’ll have to build a preamp to send a bigger signal.

As soon as i can organize the assembly a bit, I’ll create a post with the step by step and the results

Thanks again!
