Thanks, I'll be more careful and use paste and copy. Okay, what do I do now?

hi

this is the info they seek

00:1b.0 Audio device: Intel Corporation Cougar Point High Definition Audio Controller (rev 05)
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel

now open a terminal and run

Code:

lsmod | grep snd


(my example)
lsmod | grep snd
snd_hda_codec_idt      44757  1 
snd_hda_intel          21691  1 
snd_hda_codec          58364  2 snd_hda_codec_idt,snd_hda_intel
snd_hwdep              12936  1 snd_hda_codec
snd_pcm                53315  2 snd_hda_intel,snd_hda_codec
snd_seq                39539  0 
snd_timer              22027  2 snd_pcm,snd_seq
snd_seq_device         12985  1 snd_seq
snd                    38562  10 snd_hda_codec_idt,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_seq,snd_timer,snd_seq_device
soundcore              12992  1 snd
snd_page_alloc         12899  2 snd_hda_intel,snd_pcm

(now you run a mixer command if module has loaded)
alsamixer

press m to mute or unmute.....press page up or arrow up to raise volumes etc
if not sure study these images

2) if modules do not load....NOTE you will have a different codec to mine....tell us...because the mixer won't work unless alsa is running correctly

good luck

minimum to unmute is master, pcm and maybe front

Thanks everyone, it's working. I swapped out a different monitor. Not sure what happened to the speakers on the one I was using, they worked not long ago.
