Mint v19.3 audio popping

[MrEen]

so I'm using 2 drivers simultaneously

I honestly can't really explain exactly what you're using with any certainty. With snd-hda-intel blacklisted, that stuff I posted above doesn't load, and with realtek in the name, I can sort of understand that. But the aplay output made me think you didn't need snd-hda-intel anymore as everything was preceded with sof. I guess there's still some passing of info between them or something, but I do find it odd.

Usually, the dmesg output would show something similar to this instead of the realtek stuff you showed:

Code: Select all

I seem to have created a new issue... in both dsp_driver=0 and 1, my laptop speakers are working fine... but my onboard mic is not working

In the Sound menu I see 3 different mic devices under the Input section, but all of them have their volume bars greyed out and fixed at zero level

[MrEen]

Did your built-in mic work previously? And are you absolutely sure of that?

Let's see the output of this:

Code: Select all

grep snd-hda-intel /etc/modprobe.d/*

We may have caused this if the mic did work previously, but we can hopefully unwind the change that caused it.

[jalin]

MrEen,

Mic was working yea. I've tried the various dsp_driver numbers but internal mic doesn't seem to work anymore

Code: Select all

/etc/modprobe.d/alsa-base.conf:# options snd-hda-intel power_save=0 power_save_controller=N
/etc/modprobe.d/snd-hda-intel.conf:options snd-hda-intel power_save=0

[MrEen]

Okay, go back to dsp_driver=3.

Then add this to the bottom of /etc/pulse/default.pa:

Code: Select all

load-module module-alsa-source device=hw:0,6

Adding that is done with xed admin:///etc/pulse/default.pa. Save the file and reboot. Run alsamixer after booting up and check volume levels for everything. All the new PGA things should be set to 100%. Hopefully that'll get the mic working, but I can't remember if you had sound or not with that.

[jalin]

dsp_driver=3 gives a continous boombuzz as before

in quite a pickle now... drivers 2, 1, and 0 all now also give no output - as well as no input

[MrEen]

This should get you back to where you started I believe:

Code: Select all

sudo rm /etc/modprobe.d/alsa-fix.conf

Finish with a reboot.

[jalin]

nothing -- no input or output... tried different dsp drivers. Pulseaudio doesn't want to start

[jalin]

so weird... I'm getting sound output from speakers but nothing shows up in Sound menu, and my controls have no ability to control volume

[MrEen]

Let's see this output again:

Code: Select all

dmesg | grep -C1 -E 'ALSA|HDA|sof|HDMI|snd[_-]|sound|hda.codec|hda.intel'

Also, the output of apt policy pulseaudio as well.

With all these changes we've made, I'll bet we confused pulseaudio. Delete the files in /home/YourUserName/.config/pulse then run pulseaudio -k in the terminal. If that produces an error, try pulseaudio --start. Also, you should delete the load-module module-alsa-source device=hw:0,6 line you added to /etc/pulse/default.pa before doing the above.

[jalin]

Quite interesting... so I did exactly as instructed, and inputs and outputs are correct and working in Sound menu (thank you)

However, upon reboot, I get a constant boom buzz, regardless of dsp_driver. I had this issue previously only on 3

*However* upon going into the Sound menu to look at inputs and outputs, the buzz stops (until reboot)

To me, that indicates the power saving feature is faulty. Run this again, and at least the constant noise should stop if I'm correct:

Code: Select all

sudo tee /etc/modprobe.d/snd-hda-intel.conf <<<'options snd-hda-intel power_save=0'

[jalin]

nice read! inputs and outputs working as before -- no constant buzz, just the standard shutdown and startup buzzes

[jalin]

MrEen, do you perchance have any ideas for this issue?

viewtopic.php?p=1840114

[MrEen]

I'm glad we got that one sorted out.

I'm afraid I've never used a laptop with Linux, and barely ever at all! Power management issues I'm not savvy about. I can say, you could try something like TLP (it should be available in the Software Manager) and it might be able to sort things out. I did see someone have success with it in the past few days, but don't remember the issue they were having.

[jalin]

no worries re power mgmt

just had another incident, not sure if this helps -- but when the laptop is unplugged with speakers plugged, can be watching something on VLC. Then once pausing the video, after about 20 seconds with the laptop unplugged, a constant boom/buzz kicks in

[MrEen]

Ahh, more of the same almost. Now that power saving is disabled, try this; In the terminal run xed admin:///etc/pulse/default.pa and when the file opens find this section:

Code: Select all

### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle

Comment out the second line so it looks like this:

Code: Select all

### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle

Save and close the file, ignore any terminal warnings, then run pulseaudio -k to pick up the change, or reboot.
