Hi Team

I decided to reinstall Debian today as i wanted a minimal KDE setup on my T14 gen 1. I fixed my usual dummy audio by doing this:

sudo nano /etc/modprobe.d/inteldsp.conf

Copy into file: options snd-intel-dspcfg dsp_driver=1

Save & Reboot

However the Mic whilst being detected and im able to turn on/off is not working and doesn’t pic up any sound.
