no sound after ubuntu upgrade to 16.04 My ALSA information is located at http://www.alsa-project.org/db/?f=c2159b1567c305b77cd51d395d33dad429926dae

uname -r
4.4.0-112-generic

aplay -l
aplay: device_list:268: no soundcards found...

modprobe snd_hda_intel
modprobe: FATAL: Module snd_hda_intel not found in directory /lib/modules/4.4.0-112-generic

After your upgrade to 16.04 assure you issue

sudo apt-get update && sudo apt-get dist-upgrade

to pickup any driver updates ... Now to try to repair your existing OS issue this

rm -r ~/.config/pulse; pulseaudio -k

When you issue the following command

find /lib/modules/$(uname -r) | grep snd

above output should contain over 250 files looking like this

/lib/modules/4.4.0-122-generic/kernel/sound/drivers/snd-virmidi.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/snd-portman2x4.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/snd-serial-u16550.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/snd-mts64.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/opl3/snd-opl3-lib.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/opl3/snd-opl3-synth.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/pcsp/snd-pcsp.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/vx/snd-vx-lib.ko
/lib/modules/4.4.0-122-generic/kernel/sound/drivers/mpu401/snd-mpu401-uart.ko

if not then issue following to seed up your sound drivers

# sudo apt-get install linux-restricted-modules-$(uname -r) linux-generic 

sudo apt-get install linux-generic
sudo apt-get install --reinstall libasound2 linux-sound-base alsa-utils alsa-tools 

if output of above looks smacked then issue this to help get the packages aligned

sudo apt-get -f install

you may need to reboot here ... before you reboot issue below to see if your audio is recognized now

lspci -v | grep -A7 -i "audio"

you should see something like this

00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD] FCH Azalia Controller (rev 01)
 Subsystem: Hewlett-Packard Company FCH Azalia Controller
 Flags: bus master, slow devsel, latency 64, IRQ 16
 Memory at feb40000 (64-bit, non-prefetchable) [size=16K]
 Capabilities: <access denied>
 Kernel driver in use: snd_hda_intel
 Kernel modules: snd_hda_intel

If not then reboot to pickup above drivers ... now audio ? If its fixed please tell us if you needed to reboot or not ?

if not then update your question with your output ... see if your sound card is getting linked to your OS by issuing

cat /proc/asound/cards

you should see something like this

0 [Generic ]: HDA-Intel - HD-Audio Generic
 HD-Audio Generic at 0xfeb40000 irq 16
1 [D1 ]: USB-Audio - Audioengine D1
 2010 REV 1.7 Audioengine D1 at usb-0000:00:12.0-3, full speed

if not update your question with your output ... If still no go then jump into doing this https://wiki.ubuntu.com/PulseAudio/Log

If you are on a laptop/desktop I would boot the machine using a liveCD of ubuntu 16.04 from either a USB stick or DVD ... download the ISO file then burn on to USB stick using unetbootin ... once booted from that known solid OS does sound now work ? If not then its your hardware. If good sound then your above OS is shaky and you may consider to wipe the box with a fresh ubuntu 16.04 instead of the always suspect upgrade from existing prior OS

Are you on something other than laptop/desktop like a System-on-a-Card machine ?
