sorry for chiming in here with the truly thoroug job you are doing. I have found that to use hmdi sound output in pavucontrol you have to turn of the built in audio setting in pavucontrol and it works every time.
Dont be sorry. I actually appreciate the help. The more people involved, the better and the quicker a resolution to this.
@MatteP I have a few options that could be exercised. One of them would be to install linux-lts which is a different kernel that might provide better performance, etc. But that is another action if all does not go well.
The other one is removing what you have now and installing OSS (mentioned earlier). Again, if all does not go well following continuing procedures, we can try those. Not give up yet.
The next thing we will do is open
alsamixer again, and unmute the devices. You can do this with
M You have to make sure that each column says
00 under each.
Or you can do that with the following
alsamixer -c 0
From the Arch Wiki:
Note: alsamixer will not tell you which output device is set as the default. One possible cause of no sound after install is that PulseAudio detects the wrong output device as a default. Install pavucontrol and check if there is any output on the pavucontrol panel when playing a .wav file.
You must do that. You should play a
.wav file. The Arch Wiki is a superb resource and tool. It is thorough and well written. I suggest to become friends with it.
Question #1: The application that you are using to play files with. What application is it? Do you have the obvious engaged? That is, do you have volume up? Is volume muted or low? Ensure volume levels.
Next thing if the above does not work is to start up your application for playing music and do the following:
pacmd list-sink-inputs Also, play a video from Youtube. This is also an application that may or may not have output in the above command.
Post the full output here. This is being done to rule out other things and to investigate other avenues.
Also, post the full output of
amixer -c 0 contents
Question#2: Have you tried to see if you have sound through your headphones plugged into you headphone jack? Do you have sound available via that route? State the answer here.
Post the full output of each command here.
