No sound, sound card not detected but shows up in lspci, everything worked fine last week
Hi,
I'm new to this so please let me know if I should be making this post differently.
I'm running Ubuntu 16.04 LTS on a Dell XPS 13 (pre-installed). Everything was fine a week or two ago. Then the sound got glitchy (changing the volume through audio settings sometimes wouldn't change anything) and then disappeared altogether. I went through applicable portions of https:/
What I'm seeing:
- There is no drumming sound on startup (there used to be)
- There is no sound playing from any other application (aplay, chrome, etc)
- Nothing is muted
- Neither laptop speakers nor headphones produce any sound
- Previously when I plugged in headphones, there would be a dialogue asking if I plugged in headphones or a headset. Now when I plug in headphones, no dialogue pops up. The rest of the diagnostics are for when there aren't headphones plugged in.
- A sound card shows up in lspci:
00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21) (prog-if 80)
Subsystem: Dell Device 075b
Flags: bus master, fast devsel, latency 32, IRQ 134
Memory at dc428000 (64-bit, non-prefetchable) [size=16K]

Kernel driver in use: snd_hda_intel

- "cat /proc/asound/cards" outputs "--- no soundcards ---"
- output from alsa-info.sh from step 3 of troubleshooting guide:
