Lost sound through speakers

[Metal Mick]

Hi all,

I'm in a spin of MX-KDE with AHS support (provided very helpfully by dolphinoracle) and all has been well until recently when i lost sound output through the speakers in my laptop.

I can still get sound via BT, and in Windows all sound functions are okay.

Someone in another thread lost all sound and video, and a Konsole check that all updates had been properly installed with "sudo dpkg --configure -a
". I have tried this and found no difference.

This is a dump of system info:

I don't often use the sound form the laptop speakers, but I sometimes plug in earbuds.

I'd appreciate any and all help with resolving this issue.

[Huckleberry Finn]

Code: Select all

echo 'options snd-intel-dspcfg dsp_driver=1' | sudo tee /etc/modprobe.d/sound.conf

Code: Select all

echo 'options snd-hda-intel model=dell enable=yes' | sudo tee /etc/modprobe.d/sound2.conf

Reboot.

[Metal Mick]

Thanks for the suggestion. I tried it and sound comes through the speakers that are part of my external monitor. The laptop speakers remain silent, when I disconnect the monitor.

There are times when I am away from my monitor and would like to get some sound. Is there some modification to either of the 2 sound config files that I can make so that I can include the laptop speakers as an output device?

I have found the file pc-speaker.conf. In it there is the entry "blacklist pcspkr" - would commenting that out let me use the laptop speakers for sound?

I'll try it. I did. Nothing worked: I tried all permutations I could think of in pc-speaker.conf to no avail. I have returned the file to it's non-fiddled-with condition.

[Huckleberry Finn]

Have you tried Alsamixer from menu?

After you open it: F6 and select "0 Intel" (rather than "default") then press F5 , now play with the bars. Any item may be even at max, still muted. Under the bars: MM means muted , 00 : unmuted. M from keyboard mutes/unmutes.

[Metal Mick]

Thanks for your further suggestion - I appreciate it. I'm sorry to take so long to reply: time zone difference here in Australia.

I tried Alsamixer several times, and again no success. Checked for muted items - I fell for that on my previous installation (older laptop) and was looking out for it.

I'm sure the laptop speakers were working when I first installed.

EDIT: it's quite likely the speakers didn't work from installI just booted up with my live MX-KDE-AHS thumbdrive, and after installing the drivers, found that the speakers were marked as "unavailable". This didn't stop music coming through my earbuds that I plugged-in.

[Huckleberry Finn]

Code: Select all

rm -r ~/.config/pulse

Reboot (or Logout, Login ) will reset Pulseaudio settings to defaults.

[Metal Mick]

Thanks, I'll try this reset next:

Code: Select all

rm -r ~/.config/pulse

Reboot (or Logout, Login ) will reset Pulseaudio settings to defaults.

[Huckleberry Finn]

Probably that won't work, too, however you can still do it, no harm .

The main problem is that it's the same everywhere with that device: 8086:51c8 (all distros, even the bleeding edge ones). And the weird thing is that sometimes it's ok with (say) kernel 5.15-38 and not with 5.15-43 then ok with 5.19.xx then not with 6.0.x ...

And (actually) the real problem is (as always) driver: sof-audio-pci-intel-tgl

So, what we did with the 1st command was to make it use the (traditional/classic) snd_hda_intel instead.


Whatever... we may be very close to the solution:


Could you just copy-paste here the "Chip" line from Alsamixer ? (Top-left corner)

i.e.

Chip: Realtek ALC298

or

Chip: Realtek ALC1220

or whatever.

[Metal Mick]

Hi, H-F,

the contents of "Chip": PulseAudio
"Card" is also PulseAudio

I was considering moving to Pipewire purely because in my MX-19-KDE on a previous laptop, the audio became somewhat problematic towards the end.

Might this be worth trying, and attempting to fix that if it misbehaves.

Also, I'm on Kernel 6.0; I could always roll back to an earlier kernel if you feel it's worth a try. I take it I just have to uninstall via the Package Manager?

[Huckleberry Finn]

Let's delete the file we created first:

Code: Select all

sudo rm /etc/modprobe.d/sound.conf

Reboot.

(Now it should return to sof driver.)

Does it now show anything different in Alsamixer? (Chip and any others)


You don't have to uninstall the 6.0. You can (if you like) install any kernel (say 5.15) then boot with it via "Advanced Options" on Grub. Furthermore, yours is currently 6.0.0-4, you can even check the 6.0 and install (which will install at the moment linux-image-6.0.0-6mx-amd64-unsigned_6.0.12-1) and try the sound.

In the meantime, it may be solved by the upcoming 6.1 (without requiring workarounds...)

Pipewire ... you can try of course, but it won't take Pulseaudio's place. (At this point @AVLinux may give better info :) ). Also, distros like Fedora, Garuda (and many bleeding edge ones) have both Pipewire and kernel 6.0 ootb, still same problem there with the same card. (You can even try them on live session if you like).

The reason why I asked the Chip no: We used model=dell as the option (which's generic and works on most Dells). This way we can try a more model-specific option.
