Sound Card not being detected on Ubuntu
 

Recently, I installed Ubuntu onto my brand new desktop, it's worked great so far and I haven't had any problems (crashes and the like) Well that is to say, except for one... There is no sound. I'm not completely sure why, but when I go into sound settings it doesn't detect a sound card. I've tried all the mainstream solutions, and none of them seemed to do anything useful, asking for help here was kind of my last resort.

If theirs anyone who perhaps knows a solution to my problem, and how I can get Ubuntu to recognize my sound card, it would be appreciated. Thanks in advance.

Hi brother (or sister)...

I'm not sure if I can help but my initial guess here is that the driver is either missing (not released yet) or not loading correctly. If you would, please follow the instructions here and either post the results or provide a link to them. Thanks! :)

Regards...

Brother.



Thank you for your response; I followed the steps and got this link: http://www.alsa-project.org/db/?f=2f...8448ad6f4a776f
Again, Thank you, Brother/Sister.

Hi...

It's "brother," as well. :D

From what I've been reading (here and here,) you're not the only one to have this problem, although theirs were primarily with 14.04. While your device is already supposedly included in the kernel for your version of Ubuntu, if I'm reading the information correctly, the only thing I know to suggest at this point, is to follow the instructions on post #8 here or the official Ubuntu instructions here and see if that helps. If not, you can try upgrading to the newest stable kernel. I'm guessing it's this one.

Disclaimer: I can't guarantee any of the above will not cause unwanted changes or damage to your operating system (Ubuntu 16.04,) proceed at your own risk. ;)

You can also wait to see if another member might have a better suggestion.

Try and check which module is used (last line). Try to load that module.

@Axon9000: If you get a result with AwesomeMachine's suggestion, you can try loading it with the modprobe command. :)

According to the paste posted earlier snd_hda_intel is loaded. HDMI sound is enabled. The analog part is not working. There are sub-drivers for snd_hda_intel not shown on lspci -k output. Here is the output from one of my boxes, similar hardware. Linky.
I honestly don't know why there is no analog sound. It seems snd_hda_intel has no sub-driver for chipset in use. Loading a newer kernel or newest out-of-kernel ALSA drivers is probably the solution.

Thanks for that, unfortunately the two tutorials you sent me did not work, I'll be working on upgrading the kernel next.

OK, so I put the command in and got this: 00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)

DeviceName: Onboard Audio
Subsystem: Hewlett-Packard Company Sunrise Point-H HD Audio
Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Interrupt: pin A routed to IRQ 255
Region 0: Memory at df420000 (64-bit, non-prefetchable) [disabled] [size=16K]
Region 4: Memory at df400000 (64-bit, non-prefetchable) [disabled] [size=64K]
Capabilities: <access denied>
Kernel modules: snd_hda_intel
00:1f.4 SMBus: Intel Corporation Sunrise Point-H SMBus (rev 31)
Subsystem: Hewlett-Packard Company Sunrise Point-H SMBus

The interesting thing is that the access appears to be denied on the module; or maybe that's for something else I'm not sure. Anyway, I tried adding it with the modprobe command; however I was denied access.

$ sudo modprobe snd_hda_intel
modprobe: ERROR: could not insert 'snd_hda_intel': Required key not available

I guess the only thing I can try now is to update the kernel. Hopefully I don't break thing worse than they already are. Wish me luck! :)

Hi...

Do any of the suggestions here help?

If you need to go this route, you have my best wishes and prayers. :)

$ cat /proc/asound/cards

It should list your "known" hardware there. Otherwise you're missing some stuff which might just be a package manager away. Also make sure it's not muted (alsamixer). And make sure snd-* modules are loaded (lsmod). And make sure the user is in the audio group (groups / id).

Look at OP's paste in an earlier post, there is no driver loaded for analog sound. Here is similar setup with analog loaded. See the difference?

HDMI audio is not the default. The default being hw:0,0 in terms of alsa naming conventions. HDMI audio is often hw:0,3.

$ egrep -r -i hdmi /proc/asound/*

Where the .../card0/pcm3p/... would be card 0 device 3 aka hw:0,3. Or to over simplify it in a non-pulseaudio world.

FILE:.asoundrc
#----------
defaults.ctl.card 0
defaults.pcm.card 0
defaults.pcm.device 3

In pulseaudio it should be selectable in the pavucontrol program. Assuming that the rest of the bits are as they should be.
