Does anyone know how to cure the occasional crackling sound which seems to exist with HDA audio cards? This occurs with other OSs (e.g. Ubuntu and Fedora) but not with others and seems to relate to power saving options. Many thanks

Can you post
readout from terminal so we can see your sound card and also the readout of
also.

Thanks. The details are:-

What is the make of your computer.

You might have to edit /etc/modprobe.d/modprobe.conf (I am not on my AntiX box to see if it has this file at the moment)

And add to the end of the file
If a Hewlitt Packcard a guy did

I added:
options snd-hda-intel model=ref

To:
/etc/modprobe.d/alsa-base.conf

Be sure to backup /etc/modprobe.d/modprobe.conf before making any changes.
I keep a new folder called backups in /home that I move my backups to. For stuff like this because I have had to edit /etc/fstab and ~/.conky and other stuff. Happy Trails, Rok

Just so you know. I am Just a Linux using Biker. I have to experiment with my installs sometimes and edit files and such to get my gear working properly. I am by no means a Linux expert. I have to search a lot to find answers to my problems. So if my suggestions don't work. Sorry

Very many thanks. My laptop is a HP Compaq - I will try altering the etc/modprobe as the other guy did and see if this works. Nonetheless Antix is a great OS - far better for my slightly ageing laptop than better known OSs

Have you upgraded antiX since install? There is a new xorg that may fix the problem.
