volume mixer error

Arrafart

I was trying every setting yesterday and gave up. I gave up when it was set to: Default/Master

I logged in to double check and... No more error.

Since the default Mixer control for the default audio card is named Master , this is what you should set as Audio Device. As it turns out, you already found this is the working option.

@mitu thank you for clarifying. If needed on a different device, I now know how to check it and replicate.

@Arrafart i have this issue still and i need help its a black rasp pie 4 4gb running retro pie

@hughp for me it was finding the correct setting. Default/Master
Try to replicate what @mitu said above. I was lucky to reboot with the correct setting by accident.

~~I believe a reboot will be necessary ater each time you check it, but not sure.~~

Again, I was lucky and Mitu was right the day after.

No, a reboot is not necessary.

@mitu what do i need to do to fix my issue

mitu

@hughp Change the Audio settings for Card in EmulationStation to Headphones ?

hughp

@mitu its on headphones

mitu

@hughp No idea then. If the audio works in games, then the default device is set to headphone/analog on the system.

Please run the following commands and post the output:

amixer
aplay -l
