Sound not working when Audio Controller is set to "Enabled" in BIOS

[Mina]

Didn't do anything strange but the sound just stopped working for my headphones. Just like that.

I have multiple soundcards. The one affected is CA0132 which is the built-in card of the motherboard. The other card isn't affected (CA0106) and is working fine with external speakers. I also tried with a plug and play usb soundcard (USB PnP Sound Device). also not affected and is working (as expected I guess).

Tried restarting. Tried playing around with alsamixer and pavucontrol. Tried checking for updates and updating to latest. ...Didn't try doing a back-flip tho hehe XD

Had you updated your system that you can remember prior to this problem occurring? If you were to boot 14.04 live media, does the problem exist there? If you have Windows or another distro installed, does the problem occur there?

[Mina (842mono)]

Yes I always stay up to date. I'll try booting into a live usb and give feedback. Currently I have no other installed distros.

now typing through a 16.04 live usb. sound doesn't work. It shows Headphones (unplugged)

...now typing through a 14.04 live usb & still not working. Also showing Headphones (unplugged) I now remember that when I first installed 14.04 it truely wasn't working.

[Luke Yelavich (themuso)]

What if you unplug and re-plug? If that doesn't work, then its likely something may have happened to your hardware. Do you have other outputs you could test?

[Luke Yelavich (themuso)]

Ok, do you have a 16.04 image handy? You may want to consider downloading 16.04, and testing with that. If that works, then maybe its worth considering an upgrade.

[Mina (842mono)]

of course Ii tried that, but after you asked I tried again and again. Doesn't work but the thing is it's totally silent. Not glitching or anything. It seems very unlikely to me to be a hardware thing. It's a desktop. I didn't do anything. I didn't move it at all and it happened after a reboot.

However I'll keep on trying to get sound out of it.

[Mina (842mono)]

Fixed itself somehow. Updates probably

[Mina (842mono)]

Oh no it stopped working again.

But I guess this excludes hardware issues.

[Mina (842mono)]

Okay there's a BIOS setting in the motherboard. Something like "Enable Onboard Audio". I had it on "Enabled". I set it to "Auto" and the sound worked immediately! Ubuntu's drum sound came out. It never ever came out before. Sound used to work after login. Awesome 8)

Just to say, not sure of the exact names of the settings
