[Solved] Getting hdmi sound output, but no speakers or headphones

[Ulysses]

Hi, I recently switched from win10 to mint on my laptop, and can't claim to have any prior experience with linux based os's.
So far I'm having a couple of issues, and I'm hoping I could find some help here.

I've tried reloading alsa with no result, I'm also getting no sound in the live version when I boot from usb.
I did a sound test in the pc BIOS which worked fine, so I doesn't seem to be a hardware problem.
I've installed PAVC, but only hdmi outputs are displayed as an option.
Let me know if you can help, and if there's anymore info you need from me. I'd love to get this issue resolved so I can get my laptop back to a funcitonal state.

Known issue with your device. Seems to depend on BIOS and kernel version and a few other factors, see here:
https://wiki.archlinux.org/index.php/De ... 343)#Audio

Based on that I'd say before changing anything, first try this in a terminal window:

Code: Select all

sudo modprobe -r snd_hda_intel; sudo modprobe snd_hda_intel index=1,0

You might have to reload alsa again after that as well to see the effect, if any, not sure.

A BIOS update seems like a sensible idea to explore no matter what.

If you want to try the latest 4.18 kernel series, I explained here how to do that at the moment: viewtopic.php?p=1525706#p1525706 - I doubt this will make a difference given how old your hardware is but you never know, might help in particular in combination with the latest BIOS.

There's also this bug report https://bugs.launchpad.net/ubuntu/+sour ... ug/1413446 mentioning this workaround:

A workaround is to pass acpi_os='!Windows 2013' as a kernel parameter, but this is non-optimal since the mode of the touchpad is affected. It also results in an alternate, less used and tested path in the firmware to be used.

Thanks for the quick reply!

I tried the modprobe first, but it didn't really do anything. Then I updated my BIOS to the newest version and now everything works!
Thank you so much, now I can get back to familiarizing myself with linux.

I've marked my post as solved in the title, let me know if there's anything else I need to do on my end.

Nope, you're all good, I just threw everything at you that I had, glad something stuck.
