I am on 24.04 LTS, and since upgrading to it, the system makes a pop sound before producing the sound. It's quite annoying. It's like "POP" before a song plays. I tried:
echo "0" | sudo tee /sys/module/snd_hda_intel/parameters/power_save
ya its the Line out. That command seems to have fixed it. Because I don't know how to make it a permanent change I added the command to startup during boot. Thanks for your help!
