I showing a number of similar errors. I've altered the asla.conf to comment out as many cards as I felt safe.
Here is what I have left and I'd like ideas on how to stop most of these errors.
to be clear I'm on an old Dell optiplex desktop running Ubuntu 24.03 by the grace of God and a new Saplos Radeon 1/2 height video.
Code:
#$ alsactl init 0Found hardware: "HDA-Intel" "Realtek ALC269VB" "HDA:10ec0269,10280577,00100100" "0x1028" "0x0577"Hardware is initialized using a generic methodOnly 2 devices and only one valid as my speaker is actually plugged into the audio out on my box.
