I have a Dell XPS 13 (9350) with Manjaro XFCE (Kernel 5.4.72) and I have a static noise on headphones all the time. From pavucontrol, there’s no option to fix that. When I was using Ubuntu, this problem could be easily fixed by increasing the dB of headset to 10 in alsamixer. Nevertheless, in Manjaro changing this option doesn’t make any difference on the sound… Any idea on how to improve the sound and stop this static noise?
I did, but unfortunately it didn’t solve the problem… The weird thing is that modifying stuff in amixer or alsamixer has no effect at all on the sound. I can turn up and down the ‘Headphone Mic Boost’ on the HDA intel PCH, and it doesn’t change anything. Usually I should listen a high pitch sound if turning it up… Only the master volume has an effect on the sound. I suppose it’s because pulseAudio is the default card over this card but still. I don’t really understand.
Additionally, I saw this message on the bottom of the solution you sent me:
Note: Unfortunately, you must make the same modifications every time the PulseAudio package is updated. Additionally, this will entirely disable the internal microphone.
So… if I need to choose, I prefer to have this white noise than disabling the internal microphone
I’ve seen it could be a kernel problem or pulseAudio upgrade (sorry, cannot include links).
I upgraded pulseAudio but this made it worse… haha now I have the problem that when I turn on my computer, pavucontrol is not working, and shows this message:
“Establishing connection to PulseAudio. Please wait …” I solved the problem by launching pulseaudio --D command at startup, although not optimal solution.
Hello digitalone, thanks for the answer. I tried resetting or playing with the headset-gain with alsamixer. The problem is that it doesn’t matter the gain, it doesn’t have any effect on the noise. So doing a script to turn headset-gain to 10dB will not help. For instance amixer -c0 sset 'Headphone Mic Boost' 10dB has no effect at all. That’s the problem… I think my alsa settings are not being used. I thought maybe there’s a problem with the default card or something?
I already reinstalled pulseaudio and pavucontrol. I even tried the new version in AUR, without result.
If it can help, here the output of pacmd dump | grep -v 'module|source':
### Configuration dump generated at Sat Nov 7 15:05:58 2020
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3246 Analog [ALC3246 Analog]
Subdevice #0: subdevice #0
Any other possible explanation? Maybe the solution is to reinstall all Alsa and Pulseaudio and related stuff? Because now it got worse… even the microphone doesn’t work with some apps. One of my apps was using the alsa_input.pci[…] and there was no sound.
For instance, when I change the dB in alsamixer to 10dB; then I check in pacmd list sinks and my base volume is still 0.00dB. I guess that changing the configuration with alsamixer should change the 0.00dB to 10dB. Maybe if I could change the base volume with pactl that could solve the problem, although no idea how to.
