Sound card stopped working all of a sudden

Hi everyone,

Yesterday I was playing a bit with a Tails install on a USB stick, and then back to my Arch install I realized the sound was not working anymore: PulseAudio only shows a "Dummy output". Investigating a bit I realized that, now, there's no audio device at all when I do lspci Here's the output of lspci -nnk

Looking at journalctl, there used to be mentions to snd_hda_intel and snd_hda_codec_realtek, but since yesterday they disappeared completely. I haven't changed the kernel nor anything like that, but just to be sure, I have tried the LTS kernel and there too I have the same issue.

All of this happened in a ASUS UX330UA. I can still have normal audio output if I connect my Bluetooth headphones to the laptop.

Is my sound card really fried? Is there some way to test it, besides installing Windows?
Also, could the Tails USB stick have anything to do with it? It's a weird coincidence...

Many thanks!

Re: Sound card stopped working all of a sudden

Well, as mysteriously as it stopped working, it started working again... I've rebooted from the LTS kernel to the LTS kernel again and the sound card showed up. Not really sure what happened here...
