Hi everyone

I’m using ubuntu12.04 on Beaglebone Black

Sound just doesn’t work!!! :frowning:

It’s not mute!

I have installed audio codecs on ubuntu, music will paly, but no sound from monitor!!!

What is the “Dummy Output”?

How can I use a correct sound driver for my BBB?

Is it because of the audio is over HDMI?

I was using debian and lxde ui, sound was working correctly!

Can anyone help me?

Thank you

I heard 14.04 is more laggy than 12.04 on BBB, is it right?
Sound works fine in 14.04?

ubuntu@ubuntu-armhf:~$ uname -r
3.14.4.1-bone-armhf.com

Not sure what you've been smoking...

Sound works fine in 14.04?

It works with the default 3.8.x and 3.14.x-ti kernels.

ubuntu@ubuntu-armhf:~$ uname -r
3.14.4.1-bone-armhf.com

So, you recommend to use 14.04, ha?

I do recall someone cough saying about a year or more ago. That Ubuntu 12.04 was a pain in the backside to maintain, and hence would likely be unsupported in the future . . .

One guess whom I remember saying that ?

Nah, it's ubuntu... it's hard to recommend them..

Use the default image..
