First post, so forgive any faux pas!

I've had this problem since Mint 18.x, and putzed around every so often, but need to fix it so it doesn't interrupt my workflow as much.

When going to sleep or at bootup, my built-in soundcard does not show. Rather, it goes to via HDMI2 to a second monitor. On "Sound Settings" the "Built-in Analog Stereo" will disappear, leaving only HDMI/DisplayPort2

pulseaudio -k will tend to activate it, although I just use pavucontrol and choose "Configuration" and choose "Audio Stereo Output" and then everything works perfectly fine.

I've tried a few solutions online that were mostly Ubuntu, but none of them seemed to fix it permanently. The sound was incredibly loud on install, but I did find an online solution for that.

Hi dismasop, and welcome to the forum.

On the Configuration tab of pavucontrol, is there a separate HDMI Profile you can set to Off? Or are all settings under one Profile?

Your inxi results lead me to believe it's the latter. If it's the former, set the HDMI Profile to Off and you should be good. If it's the latter we have a little more work to do.

In the terminal enter pacmd list-sinks | grep -e 'name:' -e 'index:'. Here's my output for reference:

Code: Select all

scott@scott-HP ~ $ pacmd list-sinks | grep -e 'name:' -e 'index:'
  * index: 0
	name: <alsa_output.pci-0000_00_14.2.analog-stereo>
    index: 1
	name: <alsa_output.platform-snd_aloop.0.analog-stereo>
    index: 2
	name: <alsa_output.pci-0000_00_01.1.hdmi-stereo>
scott@scott-HP ~ $ 

Yours should have a line similar to alsa_output.pci-0000_00_1f.3.analog-stereo. Then in the terminal enter xed admin:///etc/pulse/default.pa. It'll ask for your password which may not show anything as you type, just type it and hit Enter.

Once the file opens, scroll to the bottom and change this line:

Code: Select all

#set-default-sink output

to this:

Code: Select all

set-default-sink alsa_output.pci-0000_00_1f.3.analog-stereo

making sure you used what your line showed if my example wasn't 100% the same.

Now save the file, run pulseaudio -k in the terminal so pulseaudio reloads the config and your issue should be gone.

Good luck.

That seems to have done the trick, thank you!

I just also noticed that if I went to pavucontrol and chose the HDMI before I applied the fix, the Built-in Audio disappeared from the Sound Settings entirely. Interesting.

You're welcome. Glad you're fixed.
