Mint 19.1 No sound/output devices

Post by DukePookums » Fri Mar 29, 2019 6:42 pm

Hi all,
Just started off with my first linux system, so far it's fine but I cannot get any sound unless I am listening through headphones. From what I've been able to read from other support threads, I think that I'm missing an audio output port. On the 'Output Devices' tab of PAVU, I only have 'Headphones (unplugged)' under options for 'Port'. I could really use some help getting this going!

EDIT: Solution turned out to be a BIOS issue, the audio was set to OFF

What I've tried so far:
Reinstalling Alsa and pulse with

Code: Select all

sudo apt-get remove --purge alsa-base pulseaudio

sudo apt-get install alsa-base pulseaudio

And force reload Alsa again:

sudo alsa force-reload
Deleting the files out of config/pulse

Try this:
Update Manager - panel: View - Linux kernels
Install the latest kernel from the 2.18 4.18 series. Then reboot.

---Edit: changed 2.18 in 4.18 (oops). :P

Hi DukePookums, and welcome to the forum.

I'm suspecting your system needs a special setup for audio based on the lsmod results. I'll need to see the results of aplay -l to determine the correct fix.

Pjotr meant the 4.18 kernel, and that may also fix the issue.

I will try loading Kernel 4.18 tomorrow,4.18.0-16 is the highest available, supported until 8/19. Is that the kernel I should try?

below are the results of aplay -l

Well, I was wrong about the special setup in the way that I was thinking. I was thinking you had a SoC issue because of your lsmod showing this:

Code: Select all

snd_hda_ext_core       24576  1 snd_soc_skl
snd_soc_sst_dsp        32768  1 snd_soc_skl_ipc
snd_soc_sst_ipc        16384  1 snd_soc_skl_ipc
snd_soc_acpi           16384  1 snd_soc_skl
I am not sure why you have soc modules loading. I'm wondering if your BIOS/UEFI is misreporting the available codec slots.

Let's see if dmesg | grep -C1 -E 'ALSA|HDA|HDMI|snd[_-]|sound|hda.codec|hda.intel' gives us something better to go on.

EDIT: If my suspicion is correct about the misreporting, the newer kernel isn't going to help. If the dmesg command returns, among many other lines, snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to single_cmd mode: last cmd=0x208f8100, you'll need to edit a file to correct the situation. Will wait for the output before continuing.

WOW! That is a strange output. I am referring to this part:

Code: Select all

[    5.085745] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC3246: line_outs=1 (0x21/0x0/0x0/0x0/0x0) type:hp

[    5.085752] snd_hda_codec_realtek hdaudioC0D0:    inputs:
Here's what mine looks like with everything working properly:

Code: Select all

[   12.076062] snd_hda_codec_realtek hdaudioC2D0: autoconfig for ALC221: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:line

[   12.076072] snd_hda_codec_realtek hdaudioC2D0:      Line=0x1b
Let's try the easiest potential fix and work up from there.

In the terminal type xed admin:///etc/modprobe.d/alsa-base.conf and when the file opens scroll to the bottom and add this new line:

Code: Select all

options snd-hda-intel model=auto
Save the file and reboot. Check dmesg | grep snd and see if that section has changed. If so, try testing sound stuff. (You don't need the longer dmesg command here.)

If it's still the same, open the file again and CHANGE the line you added to this:

Code: Select all

options snd-hda-intel probe_mask=1
Save, reboot and check again.

We might have to change the probe_mask number if still not working. I'll wait and see if you have any luck with the above first.

I just found a post on StackExchange from a user of Ubuntu that has the same chip that you have. (S)he solved their issue by creating a new user, although they had done quite a few things previously. If that was really all that was needed, then there's a good chance just deleting pulseaudio's config files would've accomplished the same thing.

You could give that a shot. In your File Manager navigate to /home/YourUserName/.config/pulse and delete all the files in the folder. They will get recreated with a fresh set once you restart the sound daemon by running pulseaudio -k in the terminal.

xed admin:///etc/modprobe.d/alsa-base.conf:
returned a couple lines of error:
Latitude-7480:~$ xed admin:///etc/modprobe.d/alsa-base.conf

** (xed:11761): WARNING **: 11:02:14.065: The specified location is not mounted

(xed:11761): Gdk-CRITICAL **: 11:02:14.068: gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed


but did open the alsa-base.conf text editor, options snd-hda-intel model=auto was added to the bottom of the text file.

@MrEen, I believe i've tried that so far, but am rebooting now to try the above fix, will use yours too shortly

EDIT:

Code: Select all

options snd-hda-intel model=auto
and

Code: Select all

options snd-hda-intel probe_mask=1
did not enable any audio.
@MrEen, pulseaudio -k had no effect

The warnings can be ignored. Sorry I didn't mention that.

Try changing the line to:

Code: Select all

options snd-hda-intel probe_mask=0x100
I am more optimistic on this one, as it'll probe slots that the hardware didn't report as available.

If this one doesn't work, go into your BIOS and see if Fast Boot is enabled and try disabling it. You might need to follow that with another reboot.

UPDATE: After booting into my Windows 10 partition, I get no sound from there either, I'll keep trying to correct on that side and see if it fixes issue on Linux parition as well

Sounds good. Check the BIOS. See this post: https://askubuntu.com/questions/874756/ ... untu-16-04

Brought it back to the tech shop since I didn't have a lot of time, turned out it was a BIOS issue, problem now solved!
Thanks for your help, everyone!
