Sound card not working

[io587]

The volume adjuster on the menu bar does not allow me to adjust volume. I tried running amixer but it outputted

Code: Select all

amixer: Mixer attach default error: No such file or directory

I then tried alsactl init and some other sound-related commands but the output was

Code: Select all

alsactl: init:1758: No soundcards found...

Any clue as to how I could fix this? raspi-config doesn't allow me to adjust audio options now, either.

Which model of the raspberry pi are you using?
Which sound card are you trying to use? The raspberry's or some external adapter? (usb, i2s,...)
Which version of which OS are you using?

If using raspbian, locate the file /boot/config.txt and edit it to contain this line:

Code: Select all

audio=on

Had the same error after I accidentally deleted the config.txt file and started with a blank file. The line needed was "dtparam=audio=on"
