ALSA feedback loop
Hello,
I have a Lenovo T480 that has some sort of ALSA misconfiguration.
I determined it is an ALSA issue, as my audio stack was ALSA+PA and after removing PA the issue persisted.
Both the laptop internal microphone, and any headphone i plug in (with the 4 pin TRRS jack) also records the audio output of the system.
This means that any kind of voice call has a great amount of echo (even with headphones) and includes the music I listen to.
Basically my monitor is mixed into my microphone audio.
While this is a great bug for showing off my excellent taste in music, it can become very annoying to the other person in the call.
here's what the playback tab looks like in my alsamixer:

here's the recording tab:

This tab also has a "Digital" slider that is frozen on 50% if PA is uninstalled
The feedback volume can be reduced by reducing the playback volume in any way (e.g. if i mute the audio output, there is no feedback for the other person, but i also cannot hear them)
A friend of mine is wrestling with the exact same issue, also on arch, however i have no details about his hardware.

Re: ALSA feedback loop
Unfortunately this made no difference,
0x1d is the power input according to https://www.alsa-project.org/main/index … A_Analyzer
Am i supposed to do this on a different pin?
Also, the outputs as suggested in the other thread:

Re: ALSA feedback loop
If that isn't it, what happens if you enable the Auto-Mute Mode? It does sound like you are still simply having the audio out of the speaker and that gets picked up.

Re: ALSA feedback loop
Same thing with Auto-Mute enabled. I am 100% sure that the audio is not echoing from the speaker, it happens with headphones also, and the echoed audio is much clearer than what the microphone quality would allow.
I'm sure that the audio is feeding back as if the monitor is mixed with input, but I cannot determine why.

Re: ALSA feedback loop
I have the same issue that @ohgodwhy described.
I'm using headset, and my audio output loops back to my input, which makes other people hear everything which should be only on my audio output.
I have a Lenoveo B50-80, so it could be some kind of Lenovo + arch issue.
