No hdmi audio

[mmkw43]

all of a sudden, nothing after never having a problem. I have triple checked everything in setup and config file -- hdmi is being forced everywhere. the monitor plays audio, the connections have all been exercised and zilch.

can't even play a simple script -- even tried aplay and mpg321 -- even made sure amixer is setup right.

shutdown, rebooted you name it.

is there a problem with the PI just losing audio like this?

try no audio period.

no hdmi or analog -- yet every config item was correct for each and everything else on the pi is working flawlessly. i even get a message in terminal that aplay is playing the file but can't hear a thing.

can i reinstall a driver? anything? i've spent hours on this.

just to make this post of value -- my problem was....

amixer volume was zero and how it got that way is beyond me !


sudo amixer set PCM Playback Volume 90% (fixed it -- 90 or whatever you want)

also handy discovery --

sudo amixer set PCM mute (or unmute) (to mute the audio)

Ha ha! Yes. That has caught me out on my PC Debian systems. Boot up, no sound, WTF, spend 5 minutes checking cables, speakers and this and that.

I rarely shut these machines down so I always manage to forget it's just the mixer setting.

Wow. For those that can use MPG321 locally but get no sound from MPG321 when issuing commands from SSH and RDP, this was the fix for me.

Not sure why i got sound when consoled in locally but not through SSH, but setting the volume did the trick. Odd
