Running Ubuntu 16.04 on a Dell Inspiron 15 7579
I have tried several things to have sound in my laptop with no success, below is a list of the most relevant attempts.
Sound Output Troubleshooting https://help.ubuntu.com/community/SoundTroubleshooting.
Upgrading the kernel module to 4.6 as mentioned in Sound card not detected (16.04)
and following the referred instructions in
After trying 2. above I know the following:
The system does not recognizes my sound card.
sudo aplay -l gives
aplay: device_list:268: no soundcards found...
I do have the sound modules installed
find /lib/modules/uname -r
| grep snd shows a large list of items.
The sound card is recognized by my hardware.
lspci -v | grep -A7 -i "audio" outputs
00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21) (prog-if 80) Subsystem: Dell Device 0743 Flags: fast devsel, IRQ 255 Memory at d1128000 (64-bit, non-prefetchable) [disabled] [size=16K] Memory at d1100000 (64-bit, non-prefetchable) [disabled] [size=64K] Capabilities: <access denied> 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21)
I wanted to try the manual installation mentioned in that Sound Troubleshooting link but I don't know the name of my sound card driver in order to run
sudo modprobe snd-[NAME OF YOUR SOUNDCARD'S DRIVER].
This is what my sound configuration panel looks like, always trying to play sound through that dummy object.
Any ideas on how to solve this problem?
