You could also see if disabling Auto-Mute Mode has any effect. Once on that column, press the up or down arrow to change it.

And I don't know if we tried this exactly before, but mute the Surround, Side, Center and LFE columns. When on those columns, pressing the m key will mute them so the OO changes to MM. I know we covered something similar previously. Those columns are presently not muted, but the jack detection says they are off:

Code: Select all

numid=47,iface=CARD,name='Front Headphone Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=off
numid=40,iface=CARD,name='Front Mic Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=off
numid=42,iface=CARD,name='Line Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=off
numid=45,iface=CARD,name='Line Out CLFE Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=off
numid=43,iface=CARD,name='Line Out Front Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=on
numid=46,iface=CARD,name='Line Out Side Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=off
numid=44,iface=CARD,name='Line Out Surround Jack'
  ; type=BOOLEAN,access=r-------,values=1
Only Line Out Front Jack says on.

And, on a hunch, see if this gets the Line Out working. Reboot after running this then test the sound:

Code: Select all

sudo tee /etc/modprobe.d/front-hp-fix.conf <<<'options snd-hda-intel model=no-front-hp'
The only purpose of that is to disable the pin for the front headphone port. It doesn't tell us why that might be wanted, so just guessing that it may help in your case. If that works, we can try retasking another pin for the headphone port.

If it doesn't help, run this to undo the change:

Code: Select all

sudo rm /etc/modprobe.d/front-hp-fix.conf

Sadly none of the suggestions fixed it :(

I'm thinking it might be time for a hardware upgrade. The part thats strange is the first time I tried Mint 19.3 from a live USB the sound worked. Now I cannot get it to work at at all.

On the back there is 6 sound jacks, Do you think there is any value in trying the others? I have it plug into the line out (green) jack at the moment. I tried all 6 on Mint 20 with no luck.

What you say all makes sense about the jacks. As I showed, your output saw one thing plugged in, and to the proper port.

Did you check once again that sudo fuser -v /dev/snd/* only shows lines with your username and pulseaudio in them? Also try deleting the files in /home/YouruserName/.config/pulse then run pulseaudio -k in the terminal again.

I'll see what else I can think of.

The command

Code: Select all

sudo fuser -v /dev/snd/*

looks good and shows:

Code: Select all

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  john       1740 F.... pulseaudio
/dev/snd/controlC1:  john       1740 F.... pulseaudio
Here is the interesting part. When I try "sudo pulseaudio -k" I get the follow warnings:
E: [pulseaudio] core-util.c: Home directory not accessible: Permission denied
E: [pulseaudio] main.c: Failed to kill daemon: No such file or directory

I'm afraid that's what it should show. PulseAudio is running as a user service, not system service, so that output was perfectly normal.

I'm struggling to figure out how this could be. You've done everything correctly that could be done, and yet the issue persists.

Does the computer offer a UEFI boot option? If so, does booting a Live USB in that mode allow the sound to work? I've never known of Legacy/UEFI changes having any impact on sound, but I can't think of what else this might be.

It does have both Bios and UEFI modes, I have tried the USB in both modes and still no luck

I'm thinking of calling it a hardware incompatibility issue. Ill stick with windows for the short term and upgrade some time in the next 6 months.

Thank you so much for your help MrEen! I really appreciate it.

You're most welcome.

You might want to consider something like this. At least that should give you a headphone and mic option. USB audio is it's own sound card, bypassing the internal audio, so it should work for you.
