Adjust Minimum Sound?

M_W · 04-11-2017, 07:15 PM

Setting my volume to the lowest setting (not muted) produces no sound, but if I increase it up from there it works as expected.

I've opened up the alsamixer, and at volume level 1 the master channel is at 6 with a dB gain of -73.5. If I manually increase the master to 7 or 8, I'm able to hear audio.

Is it possible to set it so that volume level 1 is set to 8 (-65.25 dB gain) instead of 6 (-73.5 dB gain) in the alsamixer?

that is normal and expected behavior.

maybe not in alsamixer, but it is definitely possible to have that sort of fine-grained control.
try amixer.

PS:
if you're using ubuntu, you're probably using pulseaudio, which comes with its own set of audio control tools.
maybe you should use those instead.

This is what I mean by lowest setting (not muted):

write a script that loads upon boot or better yet at login that will make sure it is not muted and then set your volume to whatever you want it to be at.

i know what you mean.
it is still normal and expected behavior - setting a channel's volume to zero is not the same as muting it.

The level shown in the picture is not 0 (it's reported as 6 in alsamixer).

did you look into writing a script that insures that it is NOT muted then set to a level you want it to be when you log in yet, or given it any thought?

it can be done.

"psycho code"

Code:

#!/bin/bash

alsa unmute
alsa set vol = N

it has been my experience and others that default is mute. That is why their is many post saying "why is my sound not working"?

amixer set Master 30%,30%

i'm not sure, these two statements require more explanation i think. partial contradiction?

also i very much urge you to leave alsa things be and look at pulseaudio settings instead.

i assume you are using vanilla ubuntu since you posted in this subforum and have not supplied any additional information.
