I am running Ubuntu 18.04 LTS. I was having USB audio mutes below 35 % issue. So I followed the instructions at over here to fix it. And it worked. But now internal speakers don't work anymore.
user@hp-elitedesk:~$ pactl list short sinks
0 alsa_output.usb-C-Media_Electronics_Inc._Microsoft_LifeChat_LX-3000-00.analog-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
On the other hand PulseAudio does detect the card:
user@hp-elitedesk:~$ pactl list short cards 0
alsa_card.usb-C-Media_Electronics_Inc._Microsoft_LifeChat_LX-3000-00 module-alsa-card.c 1
alsa_card.pci-0000_00_1f.3 module-alsa-card.c
Doing sudo alsa force-reload didn't work. What can do to get my internal speakers working again?
It seems its not the first time someones internal speakers stopped working after following Chris Jean's post. I found another user on this question for whom the same thing happened. ALSA seems to be detecting the card as well.
UPDATE
I checked the output of pacmd dump and saw this:

### EOF
So clearly the set-card-profile command is the issue because its not loading a profile. So then I hunted for the profile definition in the output of pactl list and then ran:
pacmd set-card-profile alsa_card.pci-0000_00_1f.3 output:analog-stereo+input:analog-stereo
This fixed the problem and brought the sink bank. But I don't want to run this each time after I boot. Is there a work around? I realized something must be going wrong when pulseaudio is loading up. Hence, I ran it from terminal:
user@hp-elitedesk:i3$ pulseaudio
E: [pulseaudio] alsa-mixer.c: [/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common:129] Invalid value for volume-limit
E: [pulseaudio] alsa-mixer.c: [/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common:129] Invalid value for volume-limit
E: [pulseaudio] alsa-mixer.c: [/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common:129] Invalid value for volume-limit
So the suggested edit of adding volume-limit in Chris Jean's post is causing an issue. I removed the line, and then there was no problem. On the other removing that line caused the audio mute below 35% to reappear.
Does anyone know of a fix/workaround? It looks like if I want to fix the audio mute issue, then I will need to add that command to some startup script.
