[SOLVED] Something wrong with sound

from first install and yesterday, sound is working good
i don't know what happen, my sound suddenly not working (not muted in alsamixer)
i just don't know what happen, last night all is fine.
i check my terminal, i didn't change much, just install gparted from pacman (im not sure this is the cause)
i use external speaker for sound. i test speaker on my phone, it's work, so problem is in the laptop

Re: [SOLVED] Something wrong with sound

  Mono: Playback 87 [100%] [0.00dB] [off]

The "[off]" indicates that the Master channel was muted when you ran the `amixer` command (contrary to your statement in the OP).

After running `amixer set -c0 Master unmute`, does the "[off]" in the output of `amixer` change to "[on]"?

If not, please describe your audio set up in more detail.

Re: [SOLVED] Something wrong with sound

i don't know what happen

because sound not work, i want try to use my phone to be my external speaker

i install sound wire (need pulseaudio, and pavucontrol)

then connect to my phone, it's connected but no sound (i guest this sound wire is fake)

i try to open alsamixer again
the interface is different, before i install pulseaudio
there is 4 bar to control volume, master, headphone, microphones etc

but now just 1 volume control "master"
i try to unmute, then it's fine
