I'm on Debian Jessie stable x64
Code: Select all
uname -a
Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2 (2017-04-30) x86_64 GNU/Linux
The PulseAudio settings panel says "Dummy output".
My soundcard is: Realtek Audio ALC-3234 on the Dell Inspiron 5548 laptop.
snd-hda-intel was installed before, but I can't seem to reinstall that now.
Here are some potential clues, although I must admit I am relatively new to Linux so I'm not entirely sure what I'm doing:
(I'll refrain from entering any more commands I'm not sure about)

"alsa-utils is already the newest version."
I also tried this but it didn't help:
Code: Select all
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2
Thanks.
(As a side note I read that OSS has somewhat better sound than ALSA. Can OSS be installed in Debian 8.8 and is the sound any better? I listen to a lot of music and the sound is noticeably worse in Linux vs in Windows, which is a let down because I would otherwise like to remove Windows entirely... However my priority is of course resetting ALSA so I have some sound.)
